Full Text SPECIFICATION
AIR CONDITIONING CONTROL DEVICE
TECHNICAL FIELD
The present invention relates to an air conditioning control device for obtaining and
monitoring operational data related to air conditioners.
BACKGROUND ART
There are conventionally known systems that obtain data such as temperature setting
data, power consumption data, and operating mode data from air conditioners and the like
when monitoring air conditioners. The monitoring system described in Patent Document 1
given below is an example of a system for monitoring abnormal data produced by air
conditioners. In this monitoring system, when an abnormality occurs in the air conditioner,
details of the abnormality, including data on the occurrence of the abnormality and data on
the most recent operating status, are transmitted from a monitoring device that is monitoring
the air conditioner to a remote monitoring device. The details on the abnormality that have
been transmitted are then stored and collected as needed in the database for the operating data
in the remote monitoring device. Onsite service staff members can thereby promptly handle
abnormal occurrences by communicating over the internet using a portable terminal in their
personal possession to extract and receive data on the operating status from the last 30
minutes to the present from among the details of the abnormality in the database for the
operating data. That is, in the process carried out by this monitoring system, data on the
operating status within a certain recent time range is extracted from the data that has been
collected in the database for the operating data.

DISCLOSURE OF THE INVENTION
PROBLEMS THE INVENTION IS INTENDED TO SOLVE
Recently there has been concern over the depletion of primary energy sources such
as fossil fuels, and there is also a need to conserve energy in the interests of cutting down on
CO2 (global-warming gas) emissions, and the like. Research is being done on ways to
reduce power consumption using operating data such as temperature setting data, power
consumption data, and operating mode data of air conditioners and the like in the monitoring
systems of the above technology. In view of the foregoing, an object of the present
invention is to monitor operating data related to power consumption and the like in air
conditioners, and to inform users of the operating status of the air conditioner, leading to

lower power consumption.
MEANS FOR SOLVING THE PROBLEMS
The air conditioning control device according to a first aspect of the invention is an
air conditioning control device for obtaining and controlling data on an air conditioner
including a plurality of indoor units, the device comprising a data retrieval component, a data
collection component, an analysis component, and an analyzed results display component.
The data retrieval component retrieves air conditioner operating data including power
consumption data for each indoor unit. The data collection component collects operating
data at certain periods of time. The analysis component analyzes operating data for each
indoor unit. The analyzed results display component visualizes and displays the analyzed
data that has been analyzed by the analysis component
In the present invention, operating data including air conditioner power consumption
data is retrieved and collected, and analyzed data that has been analyzed based on the
collected operating data is visualized and displayed by an analyzed results display component.
The user can thus ascertain the operating status and can readily implement countermeasures
to reduce power consumption.
The air conditioning control device according to a second aspect of the invention is
the air conditioning control device according to the first aspect, the device further comprising
an power consumption countermeasure table and an extraction component. The power
consumption countermeasure table associates the analyzed data with countermeasures for
reducing power consumption. The power consumption countermeasure table is
countermeasures that allow the power consumption of the air condition as a whole to be
reduced. The extraction component extracts the countermeasures for reducing power
consumption from the power consumption countermeasure table based on the analyzed data.
The analyzed results display component further displays the countermeasures for reducing
power consumption extracted by the extraction component.
In the present invention, pre-determined power consumption countermeasures can be
displayed by the analyzed results display component based on the analyzed results. The
user can thus effectively implement countermeasures to reduce power consumption in
response to the operating status of the air conditioner.
The air conditioning control device according to a third aspect of the invention is the
air conditioning control device according to the second aspect, wherein the operating data
retrieved by the data retrieval component includes air conditioning temperature setting data,
which are the target temperature settings when the indoor units are air conditioning an indoor

area. The data collection component associates the air conditioning temperature setting data
with the power consumption data to collect the data as temperature setting-power
consumption data per indoor unit. The analysis component, based on the temperature
setting-power consumption data, selects a certain number of indoor units in order of the
greatest power consumption from among indoor units in which the target temperature setting
is lower than a first predetermined temperature setting when in cooling operation, and indoor
units in which the target temperature setting is over a second predetermined temperature
setting when in heating operation. The analysis display component visualizes and further
displays the temperature setting-power consumption data of the indoor units selected by the
analysis component.
In the present invention, the power consumption data and air conditioning
temperature setting data retrieved by the data retrieval component are associated and
collected, in the data collection component, as temperature setting-power consumption data
for each indoor unit. Based on the collected temperature setting-power consumption data,
the analysis component selects a certain number of indoor units in order of the greatest power
consumption from among indoor units in which the target temperature setting is lower than a
first predetermined temperature setting when in cooling operation, and selects a certain
number of indoor units in the order of indoor units with the greatest power consumption from
among indoor units in which the target temperature setting is a over second predetermined
temperature setting when in heating operation. The temperature setting-power consumption
data of the certain number of indoor units selected by the analysis component is further
visualized and displayed by the analyzed results display component.
The analysis component can thus select a certain number of indoor units in which
the target temperature settings are a temperature that is so low (during cooling operation) or
that is so high (during heating operation) that such a temperature cannot be recommended,
resulting in a high possibility of wasted energy. The target temperature settings and power
consumption of the selected indoor units can also be visualized to notify the user. The user
can therefore be notified of indoor units which are highly likely to be wasting energy along
with operating data, leading to countermeasures for reducing power consumption.
The air conditioning control device according to a fourth aspect of the invention is
the air conditioning control device according to the third aspect, wherein the extraction
component extracts, from the power consumption countermeasure table, countermeasures for
reducing power consumption that recommend increasing the target temperature settings of
the indoor units selected by the analysis component when in cooling operation. The

extraction component also extracts, from the power consumption countermeasure table,
countermeasures for reducing power consumption that recommend lowering the target
temperature settings of the indoor units selected by the analysis component when in heating
operation. The analyzed results display component further displays the countermeasures for
reducing power consumption that have been extracted by the extraction component.
In the present invention, the user is advised to increase the target temperature
settings of the indoor units selected by the analysis component when in cooling operation and
to lower the target temperature settings when in heating operation.
The user can thus be presented with countermeasures for reducing power
consumption, and not merely shown the operating data of indoor units that are highly likely
to be wasting energy. Effective measures for reducing power consumption can thus be
presented, and the burden on the user can be alleviated.
The air conditioning control device according to a fifth aspect of the invention is the
air conditioning control device according to the second aspect, wherein the operating data
retrieved by the data retrieval component includes power demand data which is the power
consumption data by time range. The data collection component collects the power demand
data as indoor unit power demand data for each indoor unit. The analysis component
analyzes the power demand data to calculate the peak production time during which the
overall peak power demand for the air conditioner as a whole is produced. The analysis
component also selects a certain number of indoor units in order of the greatest indoor unit
power demand per indoor unit in the peak production time. The analyzed results display
component visualizes and further displays the indoor unit power demand data in peak
production time of the indoor units selected by the analysis component.
In the present invention, the power demand data retrieved by the data retrieval
component is collected for each indoor unit in the data collection component. Based on the
collected power demand data, the analysis component calculates the peak production time
during which the overall peak power demand is produced in the air conditioner as a whole,
and selects a certain number of indoor units in order of the greatest indoor unit power demand
per indoor unit in the peak production time. The indoor unit power demand in the peak
production time in the certain number of indoor units selected by the analysis component is
furthermore visualized and displayed by the analyzed results display component.
The analysis component can thus select a certain number of indoor units in which
the indoor unit power demand is greater in the peak production time, and the overall power
demand is highly likely to be significantly affected. The indoor unit power demand of the

selected indoor units can also be visualized to alert the user. The user can therefore be
notified of indoor units in which the overall power demand is highly likely to be significantly
affected, along with the operating data, leading to countermeasures for reducing power
consumption.
The air conditioning control device according to a sixth aspect is the air conditioning
control device according to the fifth aspect, wherein the extraction component extracts, from
the power consumption countermeasure table, countermeasures for reducing power
consumption that recommend suppressing and controlling the power demand of the indoor
units selected by the analysis component. The analyzed results display component further
displays the countermeasures for reducing power consumption that have been extracted by
the extraction component.
In the present invention, the user is advised to suppress and control power demand in
indoor units selected by the analysis component.
The user can thus be presented with countermeasures for reducing power
consumption, and not merely shown the operating data of indoor units in which it is highly
likely that overall power demand is significantly affected. Effective measures for reducing
power consumption can thus be presented, and the burden on the user can be alleviated.
The air conditioning control device according to a seventh aspect of the invention is
the air conditioning control device according to the second aspect, wherein the operating data
that has been retrieved by the data retrieval component includes outdoor temperature data.
The data collection component associates the outdoor air data and the power consumption
data to collect the data as power consumption data by outdoor temperature for each indoor
unit. The analysis component analyzes the overall indoor unit trend of the indoor units as a
whole and the indoor unit trends of each of the indoor units based on the power consumption
data by outdoor temperature. The analysis component also selects a certain number of
indoor units in the order of greatest indoor unit trend displacement based on the overall
indoor unit trend. The analyzed results display component visualizes and further displays
the compared data from the comparison of the indoor unit trends and the overall indoor unit
trend of the indoor units which have been selected by the analysis component.
In the present invention, the power consumption data and outdoor temperature data
retrieved by the data retrieval component are associated and are collected in the data
collection component as power consumption data by outdoor temperature for each indoor unit.
Based on the collected power consumption data by outdoor temperature, the analysis
component selects a certain number of indoor units in order of indoor units with the greatest

displacement in an indoor unit trend based on the overall indoor unit trend. The compared
data from the comparison of the indoor unit trends and the overall indoor unit trend of the
certain number of indoor units which have been selected by the analysis component is
furthermore visualized and displayed by the analyzed results display component.
The analysis component can thus select a certain number of indoor units which are
highly likely to be air conditioning indoor areas where there is a substantial external load or
internal load. The compared data from the comparison of the indoor unit trends and the
overall indoor unit trend of the indoor units which have been selected can be visualized to
alert the user. The user can therefore be notified of the indoor units which are highly likely
to be air conditioning indoor areas where there is a substantial external load or internal load,
along with the operating data, leading to countermeasures for reducing power consumption.
The air conditioning control device according to an eighth aspect of the invention is

display component further displays the countermeasures for reducing power consumption
extracted by the extraction component.
In the present invention, the user is advised, for example, to lower blinds to block
externally radiated heat or to lower the level of introduced outdoor air having a substantial
load, so as to suppress the external load on the indoor units selected by the analysis
component.
The user can thus be presented with countermeasures for reducing power
consumption, and not merely shown the operating data of indoor units that are highly likely
to be air conditioning indoor areas where there is a substantial external load. Effective
measures for reducing power consumption can thus be presented, and the burden on the user
can also be alleviated.
In the air conditioning control device according to a ninth aspect of the invention,
the extraction component according to the seventh aspect extracts, from the power
consumption countermeasure table, countermeasures for reducing power consumption that
recommend increasing the level of outdoor air introduced into the indoor area being air
conditioned by the indoor units selected by the analysis component when there is a low air
conditioning load due to the outdoor temperature. The analyzed results display component

further displays the countermeasures for reducing power consumption extracted by the
extraction component.
In the present invention, the user is advised to increase the level of outdoor air
introduced to the indoor units selected by the analysis component.
The user can thus be presented with countermeasures for reducing power
consumption, and not merely shown the operating data of indoor units that are highly likely
to be air conditioning indoor areas where there is a substantial internal load. Effective
measures for reducing power consumption can thus be presented, and the burden on the user
can also be alleviated.
The air conditioning control device according to a tenth aspect of the invention is the
air conditioning control device according to the second aspect, wherein the operating data
retrieved by the data retrieval component includes change frequency data and changed time
range data. The change frequency data is data obtained by counting the number of times the
air conditioning temperature settings, which are the target temperature settings, have changed
when the indoor units are air conditioning an indoor area. The changed time range data is
the time range in which the air conditioning temperature settings have changed. The data
collection component associates the change frequency data and the changed time range data
to collect the data as change frequency data by time range for each indoor unit. The analysis
component selects a certain number of indoor units in the order of greatest overall change
frequency for each of the indoor units based on the change frequency data by time range.
The analyzed results display component visualizes and further displays the change frequency
data by time range for the indoor units that have been selected by the analysis component.
In the present invention, the change data and changed time range data retrieved by
the data retrieval component are associated and collected as change frequency data by time
range in the data collection component for each indoor unit. Based on the collected change
frequency data by time range, the analysis component selects a certain number of indoor units
in the order of indoor units with the most frequent overall change frequency in each indoor
unit. The change frequency data by time range for the certain number of indoor units that
have been selected by the analysis component is further visualized and displayed on the
analyzed results display component.
The analysis component thus can select a certain number of indoor units in which
the sensory temperature and target temperature settings are highly likely to be not matched.
The change frequency data by time range for the indoor units that have been selected can be
visualized to notify the user. The user can therefore be notified of the indoor units in which

the sensory temperature and target temperature settings are highly likely to be not matched,
along with the operating data, leading to countermeasures for reducing power consumption.
The air conditioning control device according to an eleventh aspect of the invention
is the air conditioning control device according to the tenth aspect, wherein the extraction
component extracts, from the power consumption countermeasure table, countermeasures for
reducing power consumption that recommend suppressing the external load on the indoor
area being air conditioned by the indoor units selected by the analysis component. The
analyzed results display component further displays the countermeasures for reducing power
consumption that have been extracted by the extraction component.
In the present invention, the user is advised, for example, to lower blinds to block
externally radiated heat or to lower the level of introduced outdoor air having a substantial
load, so as to suppress the external load on the indoor units selected by the analysis
component.
The user can thus be presented with countermeasures for reducing power
consumption, and not merely shown the operating data of indoor units that are highly likely
to be air conditioning indoor areas where there is a substantial external load. This can
therefore lead to effective countermeasures for reducing power consumption, and can also
alleviate the burden on users.

retrieved by the data retrieval component includes outdoor temperature data and data on
times when the thermostat is off for each indoor unit. The data collection component
associates the outdoor temperature data and the data on times the thermostat is off, and
collects the data as data on times the thermostat is off by outdoor temperature for each indoor
unit. The analysis component selects a certain number of indoor units in the order of the
longest time for which the thermostat is off by outdoor temperature based on the data on
times the thermostat is off by outdoor temperature. The analyzed results display component
visualizes and further displays the data on times the thermostat is off by outdoor temperature
for the indoor units that have been selected by the analysis component.
In the present invention, the outdoor temperature data and data on times when the
thermostat is off that have been retrieved by the data retrieval component are associated and
accumulated as data on times the thermostat is off by outdoor temperature for each indoor
unit in the data collection component. Based on the collected data on times the thermostat is
off by outdoor temperature, the analysis component selects a certain number of indoor units

in the order of the indoor units with the longest time for which the thermostat is off by
outdoor temperature. The analyzed results display component visualizes and further
displays the data on times the thermostat is off by outdoor temperature for the indoor units
that have been selected by the analysis component.
The analysis component can thus select a certain number of indoor units for which
the thermostat will be off for a long time and air will highly likely be blown wastefully. The
data on times the thermostat is off by outdoor temperature for the indoor units that have been
selected can be visualized to notify the user. The user can therefore be notified of the indoor
units for which the thermostat will be off for a long time and air will highly likely be blown
wastefully, along with the operating data, leading to countermeasures for reducing power
consumption.
The air conditioning control device according to a thirteenth aspect of the invention
is the air conditioning control device according to the twelfth aspect, wherein the extraction
component extracts, from the power consumption countermeasure table, countermeasures for
reducing power consumption that recommend stopping the operation of the indoor units
selected by the analysis component. The analyzed results display component further

the extraction component.
In the present invention, the user is advised to stop the operation of indoor units
selected by the analysis component.
The user can thus be presented with countermeasures for reducing power
consumption, and not merely shown the operating data of indoor units that are highly likely
to be only blowing air wastefully. This can therefore lead to effective countermeasures for
reducing power consumption, and the burden on the user can also be alleviated.
The air conditioning control device according to a fourteenth aspect of the invention

FIG. 4 is a second and third story plan of a building in which the air conditioner
monitor/support system 1 according to this embodiment is set up. The second air
conditioner 5 is an apparatus referred to as a multi-type air conditioner with a plurality of
indoor units 52a through 52f connected to an outdoor unit 51 located on the second and third
floors of the building according to the present embodiment. This is a multi-air conditioner
capable of performing the simultaneous cooling and heating operation in which cooling and
heating are automatically switched therebetween according to temperature settings. The
second air conditioner 5 set up on the third floor is the same structure as on the second floor.
Only the second air conditioner 5 on the second floor will be described here. As illustrated
in FIG. 4, the second floor of the building is only a single large room D RM21 (the third floor
is room E RM31), and six second air conditioners 5 are set up in the room D RM21. The
room D RM21 is divided into three imaginary zones: a north zone Zl on the north side, a
middle zone Z2 in the middle of the room D RM21, and a south zone Z3 on the south side.
As illustrated in FIGS. 1 and 2, the second air conditioner 5 is composed primarily of an
outdoor unit 51, a plurality of indoor units 52a through 52f (six according to the present
embodiment), a plurality of switching units 53a through 53c (three according to the present
embodiment), and a plurality of wired remote controls 34 through 36 (three according to the
present embodiment). The plurality of indoor units 52a through 52f is connected to the
same outdoor unit 51 and is related to the same air conditioning system (second or third floor
air conditioning system). The outdoor unit 51, plurality of indoor units 52a through 52f, and
wired remote controls 34 through 36 are mutually connected through the air conditioning
network 6. Two each of the plurality of indoor units 52a through 52f are located in groups
of two in each of the three divided zones, where indoor units 52a and 52b in the north zone
Zl are stored as group G4, indoor units 52c and 52d in the middle zone Z2 are stored as
group G5, and indoor units 52e and 52f in the south zone Z3 are stored as group G6 in the

grouping data in the memory 22. The three corresponding switching units 53a through 53c
are connected to the groups G4 through G6, respectively, where the switching unit 53a is
connected to the indoor units 52a and 52b of the group G4, the switching unit 53b is
connected to the indoor units 52c and 52d of the group G5, and the switching unit 53c is
connected to the indoor units 52e and 52f of the group G6. The switching units 53a through
53c are also units capable of switching between cooling operation and heating operation in
response to temperature settings set by the user. According to the present embodiment,
moreover, the two indoor units 52a and 52b of group G4 are controlled by the monitor device
2 and the wired remote control 34 set up in the north zone Z1. The two indoor units 52c and
52d in the group G5 are controlled by the monitor device 2 and the wired remote 35 set up in
the middle zone Z2. The two indoor units 52e and 52f in the group G6 are controlled by the
monitor device 2 and the wired remote 36 set up in the south zone Z3.
Monitoring of Air Conditioners
As noted above, the monitor device 2 retrieves air conditioner operating data from
the air conditioners 4 and 5 through the communications component 24. Specifically, the
monitor device 2 retrieves operating data for each of the air conditioners 4 and 5 from the air
conditioners 4 and 5, and stores the data in memory 22. Here, a year of operating data is
retrieved for each of the indoor units 42a through 42f and 52a through 52f of the air
conditioners 4 and 5. The period of time for retrieving operating data here is not limited to
one year and can be set by the user, for example to six months, a year and a half, or two years.
The operating data includes power consumption data, air conditioning temperature setting
data, power demand data, outdoor temperature data, change frequency data, changed time
range data, and data on times when the thermostat is off. What is referred to here as "power
consumption data" is data on the energy consumed by each of the indoor units 42a through
42f and 52a through 52f. What is referred to here as "air conditioning temperature setting
data" is the target temperature setting when indoor areas are being air conditioned by the
indoor units 42a through 42f and 52a through 52f, which the user can set by remote control or
air conditioning control device input component. What is referred to here as "power
demand data" is data on the power demanded by each of the indoor units 42a through 42f and
52a through 52f. What is referred to here as "outdoor temperature data" is data on the
outdoor temperature detected by a temperature sensor located in an outdoor unit or the like.
What is referred to here as "change frequency data" is data obtained by counting the number
of times the air conditioning temperature setting is changed per day for each of the indoor
units 42a through 42f and 52a through 52f. What is referred to as "changed time range data"

is data on the time range in which the air conditioning temperature setting has been changed.
What is referred to as "data on times when the thermostat is off' is data in which the
thermostat off status of the indoor units and the outdoor temperature data of the indoor units
42a through 42f and 52a through 52f in which the thermostat was off throughout the day are
associated on a room by room basis. The data processor 20 graphs each type of operating
data stored in the memory 30 in order to be displayed in the power consumption
countermeasure mode described below (there is no actual need for display output, as long as
the data is appropriately processed). The keyboard 25 or mouse 26, which are input devices
of the monitor device 2 or central remote control 3, can also be used for input by the user to
allow power consumption countermeasures from the results analyzed in each power
consumption countermeasure mode (see below) to be displayed based on the power
consumption countermeasure table 22a stored in the memory 22.
Various power consumption countermeasure modes will be described below. The
power consumption countermeasure modes are the seven modes described below. The
seven modes are illustrated in sequence using FIGS. 5 through 20. The seven modes can be
selected from a countermeasure mode selection screen SC1 (see FIG. 5), which is the initial
screen showing the power consumption countermeasure modes. Each button 71 through 77
on the countermeasure mode selection screen SC1 can be selected to move to the screen
showing the seven power consumption countermeasure modes described below.
(1) Wasteful Operation Elimination Mode
In the countermeasure mode selection screen SC1 (see FIG. 5), the wasteful
operation elimination button 71 is selected to switch to a screen SC11 that displays power
consumption classified by temperature setting. In the screen SC11 that displays power
consumption classified by temperature setting, analyzed temperature setting-power
consumption data is visualized as in FIG. 6, and is displayed on the display component 23.
(1-1) Determination of Analysis Target Period
According to the present embodiment, as noted above, the air conditioners 4 and 5
have been operated for a year, and operating data has been previously stored in the memory
22. The temperature setting-power consumption data is analyzed based on the data for the
previous year according to the season for which the wasteful operation elimination button 71
has been selected. The seasons are classified into three patterns: summer (cooling operation
period), winter (heating operation period), and an interim period, where summer is the period
from June to August, winter is the period that spans December, January, and February, and
the interim period is the period from March to May and from September to November. The

user can also change the summer, winter, and interim periods to any period by means of an
input device such as the keyboard 25 or mouse 26.
When, for example, the wasteful operation elimination button 71 is selected on July
20, 2006, since the season is summer, the operating data collected from June 1, 2005 to
August 31, 2005 will be analyzed as part of the previous year of operating data.
(1-2) Automatic Analysis and Display of Analyzed Results
In the analysis of the operating data, a maximum of three indoor units are selected in
order of the greatest power consumption, 42c, 42f, and 52e, from among the indoor units in
which the air conditioning temperature setting of each indoor unit 42a through 42f and 52a
through 52f has been set below 28°C. These are displayed along with a graph, as shown in
FIG. 6. FIG. 6 is a graph in which the air conditioning temperature settings of the indoor
units 42a through 42f and 52a through 52f are shown on the horizontal axis, and the power
consumption is shown on the vertical axis. In the graph, the indoor unit that is highly likely
to be wasting energy can be extracted because the indoor unit 42c with particularly high
power consumption can be selected from among the indoor units in which the highest
temperature setting is below 28°C in cooling operation; that is, the indoor units in which it is
highly likely that the air conditioning temperature setting has been set too low. What is
referred to here as the "highest temperature setting" is the air conditioning temperature setting
that is the highest among the air conditioning temperature settings which have been set by the
user. Here, the indoor unit 42c has been extracted. Although a maximum of three indoor
units which the results of analysis indicate as having significant power consumption are used
here, the user can specify a different number than 3, such as 1, 2, or 4, as needed. In
addition, the example here is of cooling operation, but the analysis is done in the same
manner for heating operation, in which case a maximum of three indoor units with an air
conditioning temperature setting greater than 24°C will be selected in the order of greatest
power consumption.
(1-3) Countermeasure Display
The countermeasure display button 81 in the lower right of the screen SC11 that
displays power consumption classified by temperature setting is pressed to display a wasteful
operation elimination countermeasures screen SC21 for the indoor unit 42c that has been
extracted in the results of analysis (see FIG. 7). Here, the wasteful operation elimination
countermeasures screen SC21 displays the message "The power consumption of the indoor
unit 42c has increased because the temperature setting is low. It is recommended that the
remote control temperature setting be increased." The user can therefore take specific

measures to reduce the power consumption in response to the results of analysis noted above.
Not only may the above measures be taken, but maximum and minimum air conditioning
temperature settings may be established to limit the air conditioning temperature settings so
that no user other than the air conditioning administrator can modify the settings. The menu
button 91 in the lower right of the wasteful operation elimination counter-measures screen
SC21 is pushed to return to the countermeasure mode selection screen SCI.
(2) Peak Power Mode
In the countermeasure mode selection screen SC1, the peak power display button 72
is selected to switch to a peak power screen SC12. In the peak power screen SC12, the
analyzed power demand data is visualized as shown in FIG. 8 and is displayed on the display
component 23.
(2-1) Determination of Analysis Target Period
According to the present embodiment, as noted above, the air conditioners 4 and 5
have been operated for a year, and operating data has been previously stored in the memory
22. The power demand data is analyzed based on the operating data for the previous year.
(2-2) Automatic Analysis and Display of Analyzed Results
In the analysis of the operating data, a time range T (30 minutes) in which power
demand has peaked among the days with the greatest power demand peak for the first air
conditioner 4 and second air conditioner 5 combined (see FIG. 9) is extracted from the
operating data for the previous year. Three indoor units are extracted in the order of greatest
power demand in this time range T.
When, for example, the peak power countermeasure display button is selected for
September 15, 2006, the day with the greatest power demand peak in the operating data in the
previous year from that date is extracted. If the power demand peak was greatest on August
20, 2006, then August 20, 2006 will be extracted. When the time range in which power
demand peaked on August 20, 2006 was between 2:30 PM and 3:00 PM, three indoor units
are extracted in the order of greatest power demand from the time range of 2:30 PM to 3:00
PM on August 20, 2006.
The power demand control is described here. Power demand is controlled for the
indoor units 42a through 42f and 52a through 52f of the air conditioners 4 and 5 which are
determined to be over a maximum power demand, and the air conditioners 4 and 5 are
controlled so that the overall power demand will not be more than the maximum power
demand. That is, when it appears as if the power demand will be over the maximum, the
energy to the air conditioners 4 and 5 is conserved, power consumption is economized, and

the power demand is controlled so as not to be over the maximum power demand in that time
range. During power demand control, the rooms in which an air conditioner is located are
divided into levels by the user according to the level of need for air conditioning.
According to the present embodiment, for example, room A RM11 is level 3, room B RM12
is level 1, room C is level 3, and room D is level 4. The power demand is not controlled in
level 1 indoor units 42d and 42e. When the power demand is controlled in the level 2
indoor units (no applicable indoor units), the air conditioning temperature setting is increased
1°C. When the power demand is controlled in the level 3 indoor units 42a through 42c and
42f, the air conditioning temperature setting is increased 2°C. In the level 4 indoor units
52a through 52f, the air conditioning temperature setting is increased 3°C. When the power
demand is controlled in the level 5 indoor units (no applicable indoor units), the air
conditioning temperature setting is increased 4°C. In the peak power screen SC12, the
results are graphed in order of indoor units with the greatest power demand by level in the
upper portion of the peak screen SC12, and the three indoor units 42c, 52e, and 52f are
extracted in order of the greatest power demand in the bottom portion of the peak screen
SC12.
(2-3) Countermeasure Display
The countermeasure display button 82 in the lower right of the peak power screen
SC12 is pressed to display countermeasures for reducing the power demand in the indoor
units 42c, 52e, and 52f that were extracted in the results of analysis. Here, a peak power
countermeasures screen SC22 displays this message for the indoor unit 42c: "Because the
power demand in the indoor unit 42c is high, it is recommended that the power demand
control level in the room A be increased to level 4"; displays this message for the indoor unit
52e: "Because the power demand in the indoor unit 52e is high, it is recommended that the
power demand control level in room D be increased to level 5"; and displays this message for
the indoor unit 52f: "Because the power demand in the indoor unit 52f is high, it is
recommended that the power demand control level in room D be increased to level 5" (see
FIG. 10). The user can thus take specific measures for reducing the power demand in
response to the results of analysis above. The menu button 92 in the lower right of the peak
power countermeasures screen SC22 is pressed to return to the countermeasure mode
selection screen SC1.
(3) Outdoor Air Load Determination Mode
In countermeasure mode selection screen SC1, the outdoor air load determination
button 73 is selected to switch to the outdoor air load determination screen SC13. In the

outdoor air load determination screen SC13, the analyzed power consumption data by
outdoor temperature is visualized as shown in FIG. 11 and is displayed on the display
component 23.
(3-1) Determination of Analysis Target Period
According to the present embodiment, as noted above, the air conditioners 4 and 5
have been operated for a year, and operating data has been previously stored in the memory
22. The data is analyzed based on the data for the previous year according to the season for
which the outdoor air load determination button 73 has been selected. The seasons are
classified into three patterns: summer (cooling operation period), winter (heating operation
period), and an interim period, where summer is the period from June to August, winter is the
period that spans the three months of December, January, and February, and the interim
period is the period from March to May and from September to November. The outdoor air
load determination mode is also a mode that is limited to summer or winter.
When, for example, the outdoor air load determination button 73 is selected on July
20, 2006, since the season is summer, the operating data collected from June 1, 2005 to
August 31, 2005 among the previous year of data is analyzed.
(3-2) Automatic Analysis and Display of Analyzed Results
In the analysis of the operating data, the outdoor temperature data is associated with
power consumption data for all the indoor units 42a through 42f and 52a through 52f to
prepare a correlation chart such as in FIG. 11. Here, the correlation chart is produced by
indicating the maximum daily temperatures throughout the period among the outdoor
temperature data on the horizontal axis and the power consumption of all the indoor units 42a
through 42f and 52a through 52f on the day corresponding to the highest temperature on that
day on the vertical axis. When, for example, the power consumption on a certain day in the
period is 100 kWh in the indoor unit 42c, and the highest air temperature on that day is 29°C,
this will be plotted as shown by point A in the correlation chart. In this way, the data for all
the indoor units 42a through 42f and 52a through 52f during the period is plotted in the
correlation chart, and an approximate line 1 showing the trend for all the indoor units 42a
through 42f and 52a through 52f is prepared from the correlation chart. A graph of the
displacement in the three indoor units 42c, 42f, and 52e in the order of greatest power
consumption displacement is then displayed based on the approximate line 1 showing the
trend for all the indoor units 42a through 42f and 52a through 52f. Here, three indoor units
for which the results of analysis are displayed were selected in order of the greatest power
consumption, but the user can specify a different number than 3, such as 1, 2, or 4, as needed.

(3-3) Countermeasure Display
The countermeasure display button 83 in the lower right of the outdoor air load
determination screen SC13 is pressed to display an external load countermeasure screen
SC23 for the indoor units 42c, 42f, and 52e that have been extracted in the results of analysis
(see FIG. 12). Here, the external load countermeasure screen SC23 displays the message
"The outdoor load has increased in rooms A, C, and D. It is recommended that the
introduction of outdoor air be controlled or the solar radiation be suppressed." The user can
thus take specific measures to reduce the external load in response to the analyzed results
above. The menu button 93 in the lower right of the external load countermeasure screen
SC23 is pressed to return to the countermeasure mode selection screen SC1.
(4) Comfort Maintenance Mode
In countermeasure mode selection screen SC1, the comfort maintenance button 74 is
selected to switch to a comfort maintenance screen SC14. The analyzed change frequency
data by time range (see below) is visualized on the comfort maintenance screen SC14 as
shown in FIG. 13, and is displayed on the display component 23.
(4-1) Determination of Analysis Target Period
According to the present embodiment, as noted above, the air conditioners 4 and 5
have been operated for a year, and operating data has been previously stored in the memory.
The data is analyzed based on the data for the previous year according to the season for
which the comfort maintenance button 74 has been selected. The seasons are classified into
three patterns: summer (cooling operation period), winter (heating operation period), and an
interim period, where summer is the period from June to August, winter spans the three
months of December, January, and February, and the interim period is the period from March
to May and from September to November.
(4-2) Automatic Analysis and Display of Analyzed Results
In the analysis of the operating data, change frequency data obtained by counting the
number of times the air conditioning temperature settings have been changed and changed
time range data from when the air conditioning temperature settings were changed are
associated to prepare change frequency data by time range. Here, three indoor units 42c,
42f, and 42a are extracted in order of the greatest total number of average change frequency
per day and graphed. The expression "greatest number of average change frequency per
day" indicates a high possibility that the air conditioning temperature settings of the indoor
units 42c, 42f, and 42a have not been set to the optimum temperature. The change
frequency can thus be reduced by changing the air conditioning temperature settings to the

optimum temperature. Here, the change time range involves dividing the day into the three
time ranges of morning, afternoon, and evening. Morning is the time range from 8:00 AM
to 11:00 AM, afternoon is the time range from 11:00 AM to 3:00 PM, and evening is the time
range from 3:00 PM to 5:00 PM. The air conditioning temperature setting of the indoor unit
42c has changed ten times in the morning, three times in the afternoon, and seven times in the
evening. The air conditioning temperature setting of the indoor unit 42f has changed four
times in the morning, 11 times in the afternoon, and three times in the evening. The air
conditioning temperature setting of the indoor unit 42a has changed 14 times in the morning,
and has not changed at all in the afternoon or evening.
(4-3) Countermeasure Display
The countermeasure display button 84 in the lower right of the comfort maintenance
screen SC14 is pressed to display a comfort maintenance countermeasure screen SC24 for the
indoor units 42c, 42f, and 42a extracted in the results of analysis (see FIG. 14). Here, the
comfort maintenance countermeasure screen SC24 shows three patterns: pattern A for a high
frequency of change in the morning and evening, pattern B for a high frequency of change in
the afternoon, and pattern C for a high frequency of change in only the morning. Five or
more changes in each time range are considered frequent. Although five or more changes in
each time range is considered frequent here, the number of changes per time range is not
limited to five or more and may be set, for example, as four or more or six or more. Pattern
A is determined for the indoor unit 42c, and a message is displayed: "The change in
temperature during the morning and evening is considered significant in Room A. It is
recommended that the level of outside air introduced into room A be reduced." Pattern B is
determined for the indoor unit 42f, and a message is displayed: "The outdoor load on Room C
has increased. It is recommended that the level of outside air introduced into room C be
limited or that solar radiation be controlled." Pattern C is determined for the indoor unit 42a,
and a message is displayed: "The air conditioning is working too much at startup in Room A.
It is recommended that the air level at startup be controlled." The display of these
countermeasures allows the user to take specific measures to maintain comfort in response to
the results of analysis above. The menu button 94 in the lower right of the comfort
maintenance countermeasure screen SC24 is pressed to return to the countermeasure mode
selection screen SC1.
(5) Outdoor Air Introduction Determination Mode
In the countermeasure mode selection screen SC1, the outdoor air introduction
determination button 75 is selected to switch to an outdoor air introduction determination

screen SC15. The analyzed data on power consumption by outdoor temperature is
visualized on the outdoor air introduction determination screen SC15 as shown in FIG. 15 and
is displayed on the display component 23.
(5-1) Determination of Analysis Target Period
According to the present embodiment, as noted above, the air conditioners 4 and 5
have been operated for a year, and operating data has been previously stored in the memory
22. The data is analyzed based on the data for the previous year according to the season for
which the outdoor air introduction determination button 75 has been selected. The seasons
are classified into three patterns: summer (cooling operation period), winter (heating
operation period), and an interim period, where summer is the period from June to August,
winter spans the three months of December, January, and February, and the interim period is
the period from March to May (first interim period) and from September to November
(second interim period). The outdoor air introduction determination mode is a mode limited
to the interim periods.
When, for example, the outdoor air introduction determination button is selected on
April 25, 2006, since the season is the first interim period, the operating data collected from
March 1, 2005 to May 31, 2005 among the previous year of operating data is analyzed.
(5-2) Automatic Analysis and Display of Analyzed Results
In the analysis of the operating data, the outdoor temperature data and the power
consumption data for all of the indoor units 42a through 42f and 52a through 52f are
associated to prepare a correlation chart such as in FIG. 15. Here, the correlation chart is
produced by indicating the maximum daily temperatures throughout the period among the
outdoor temperature data on the horizontal axis and the power consumption of all the indoor
units 42a through 42f and 52a through 52f on the day corresponding to the highest
temperature on that day on the vertical axis. When, for example, the power consumption on
a certain day in the period is 100 kWh in the indoor unit A, and the highest air temperature on
that day is 29°C, this will be plotted as shown by point A in the correlation chart. In this
way, the data for all the indoor units 42a through 42f and 52a through 52f during the period is
plotted in the correlation chart, and an approximate line 1 showing the trend for all the indoor
units 42a through 42f and 52a through 52f is prepared from the correlation chart.
Approximate lines ml through ml2 showing the trends for all the indoor units 42a through
42f and 52a through 52f are also prepared in the correlation chart (only m3 is shown). Here,
the approximate lines ml through ml2 are prepared for the number of indoor units 42a
through 42f and 52a through 52f, resulting in the preparation of the 12 approximate lines ml

through ml2 according to the present embodiment. For example, the approximate line m3
for the indoor unit 42c is prepared from the correlation chart in which the power consumption
data for the indoor unit 42c has been plotted. A graph of the displacement in the three
indoor units 42c, 42f, and 52e in the order of greatest displacement is then displayed based on
the approximate line 1 in which the approximate lines ml through ml2 show the trend for all
the indoor units 42a through 42f and 52a through 52f. Here, three indoor units for which the
results of analysis are displayed were selected in order of the greatest power consumption,
but the user can specify a different number than 3, such as 1, 2, or 4, as needed.
(5-3) Countermeasure Display
The countermeasure display button 85 in the lower right of the outdoor air
introduction determination screen SC15 is pressed to display an outdoor air introduction
countermeasure screen SC25 for the indoor units 42c, 42f, and 52e that have been extracted
in the results of analysis (see FIG. 16). Here, a message is displayed by the countermeasure
display. "The internal load on room A, room, C, and room D may have increased. It is
recommended that the outdoor intake level for the rooms be increased." The user can thus
take specific measures to reduce the power consumption in response to the analyzed results
above. The menu button 95 in the low right of the outdoor air introduction countermeasure
screen SC25 is pressed to return to the countermeasure mode selection screen SC1.
(6) Simultaneous Cooling/Heating Operation Energy Conservation Mode
In the countermeasure mode selection screen SC1, the simultaneous cooling/heating
operation optimization button 76 is selected to switch to a simultaneous cooling/heating
optimization screen SC16. The analyzed cooling/heating operation mode data is visualized
on the simultaneous cooling/heating optimization screen SC16 as shown in FIG. 17 and is
displayed on the display component 23.
(6-1) Determination of Analysis Target Period
According to the present embodiment, as noted above, the second air conditioner 5
has been operated for a year, and operating data has been previously stored in the memory 22.
The data is analyzed based on the data for the previous year according to the season for
which the simultaneous cooling/heating operation optimization button has been selected.
The seasons are classified into three patterns: summer (cooling operation period), winter
(heating operation period), and an interim period, where summer is the period from June to
August, winter spans the three months of December, January, and February, and the interim
period is the period from March to May (first interim period) and from September to
November (second interim period). The simultaneous cooling/heating operation energy

conservation mode is a mode limited to the interim periods.
When, for example, the simultaneous cooling/heating operation optimization button
76 is selected on April 25, 2006, since the season is the first interim period, the operating data
collected from March 1, 2005 to May 31, 2005 among the previous year of operating data is
analyzed.
(6-2) Automatic Analysis and Display of Analyzed Results
In the analysis of the operating data, the simultaneous cooling/heating operation data
and the power consumption data for all of the indoor units 52a through 52f of the second air
conditioner 5 in the room D RM21 and all of the indoor units 52a through 52f of the second
air conditioner 5 in the room E RM31 are associated to prepare a table such as in FIG. 17.
In the table in FIG. 17, the group G4 and group G6 in room D RM21 are in cooling operation,
and the group G5 adjacent to the groups G4 and G6 is in heating operation. In the room E,
all of the groups G4 through G6 are in cooling operation. The air conditioning temperature
settings of the second air conditioner 5 in the room D RM21 and the room E RM31 is 24°C.
This is displayed in the graph in the lower part of the table in the order of greatest power
consumption.
(6-3) Countermeasure Display
The countermeasure display button 96 in the lower right of the simultaneous
cooling/heating operation optimization screen SC16 is pressed to display a simultaneous
cooling/heating operation optimization countermeasure screen SC26 for the second air
conditioner 5 in the room D RM21 which has been extracted in the results of analysis and is
over the standard power consumption Wb (see FIG. 18). Here, the simultaneous
cooling/heating operation optimization countermeasure screen SC26 displays the message:
"Cooling and heating are operating simultaneously in room D. It is recommended that the
temperature setting in room D be lowered to make the operation mode consistent with either
cooling or heating." The user can thus take specific measures to reduce power consumption
in response to the analyzed results above. The display returns to the countermeasure mode
selection screen SC1 when the menu button 96 in the lower right of the simultaneous
cooling/heating operation optimization countermeasure screen SC26 is pressed.
(7) Mode for Optimizing Number of Operating Units
In the countermeasure mode selection screen SC1, the button 77 for optimizing the
number of operating units is selected to switch to a screen SC1 7 for optimizing the number of
operating units. The analyzed data on times when the thermostat is off by outdoor
temperature is visualized on the screen SC17 for optimizing the number of operating units as

shown in FIG. 19 and is displayed on the display component 23.
(7-1) Determination of Analysis Target Period
According to the present embodiment, as noted above, the air conditioners 4 and 5
have been operated for a year, and operating data has been previously stored in the memory
22. The data is analyzed based on the data for the previous year according to the season for
which the button 77 for optimizing the number of operating units has been selected. The
seasons are classified into three patterns: summer (cooling operation period), winter (heating
operation period), and an interim period, where summer is the period from June to August,
winter spans the three months of December, January, and February, and the interim period is
the period from March to May (first interim period) and from September to November
(second interim period). The mode for optimizing the number of operating units is a mode
limited to the interim periods.
When, for example, the button for optimizing the number of operating units is
selected on April 25, 2006, since the season is the first interim period, the operating data
collected from March 1, 2005 to May 31, 2005 among the previous year of operating data is
analyzed.
(7-2) Automatic Analysis and Display of Analyzed Results
In the analysis of the operating data, the outdoor temperature data and the data on
times when the thermostat is off for the indoor units 42a through 42f and 52a through 52f are
associated to prepare a table such as in FIG. 19. In this table, the number of indoor units for
which the thermostat is off all day is summarized by outdoor temperature for each room.
This is displayed in the order of rooms with the greatest number of stopped units. When, for
example, the outdoor temperature is 19°C as shown in FIG. 19, the thermostat is off in two of
the indoor units 42a through 42c (indoor units 42a and 42b) in room A RM11, and the
thermostat is off in one of the indoor units 42d and 42e in room B RM12. Although not
shown in FIG. 19, the thermostat is off in none of the units in room C RM13, room D RM21,
or room E RM31.
(7-3) Countermeasure Control
When the countermeasure button 87 in the lower right of the screen SCI7 for
optimizing the number of operating units is pressed, the number of operating units is
optimized for the indoor units 42a through 42c in room A RM11 extracted in the results of
analysis, and the number of units is controlled by the control component 27 so that only one
indoor unit (such as indoor unit 42a) is operated in room A RM11. The number of units in
room B RM12 is controlled by the control component 27 in the same manner as room A

RM11 so that only one indoor unit (such as indoor unit 42d) is operated.
Features
(1)
In the present invention, the operating data of the air conditioners 4 and 5, such as
power consumption data, air conditioning temperature setting data, power demand data,
outside temperature data, change frequency data, changed time range data, and data on times
when the thermostat is off, is collected in the memory 22 through the communications
component 24. The collected operating data is analyzed by seven power consumption
countermeasure modes, and the analyzed data is visualized and displayed on the display
component 23. Power consumption countermeasures which have been predetermined on the
basis of the analyzed data are also displayed on the display component. The user can thus
ascertain the operating status and can take specific measures to reduce the power
consumption.
(2)
In the present invention, power consumption data and air conditioning temperature
setting data retrieved via the communications component 24 are associated and collected in
the memory 22 as temperature setting-power consumption data for the indoor units 42a
through 42f and 52a through 52f. Based on the temperature setting-power consumption data
stored in the memory 22, the data processor 21 extracts three indoor units 42c, 42f, and 52e in
the order of greatest power consumption from among the indoor units in which the air
conditioning temperature setting is below 28°C when in cooling operation. The temperature
setting-power consumption data for the three indoor units 42c, 42f, and 52e extracted by the
data processor 21 is also graphed and displayed on the display component 23. The user is
also advised to increase the target temperature settings in the indoor units 42c, 42f, and 52e
extracted by the data processor 21.
The data processor 21 can thus extract the three indoor units 42c, 42f, and 52e in
which the target temperature setting is a temperature that is so low that such a temperature
cannot be recommended, and which are highly likely to be wasting energy. The power
consumption and the target temperature settings of the extracted indoor units can be graphed
to notify the user. The user can therefore be notified of the indoor units which are highly
likely to be wasting energy, along with the operating data, leading to countermeasures for
reducing power consumption. The user can also be presented with countermeasures for
reducing power consumption, and not merely shown the operating data of the indoor units
42c, 42f, and 52e which are highly likely to be wasting energy. This can therefore lead to

effective countermeasures for reducing power consumption, and can also alleviate the burden
on the user.
(3)
In the present invention, power demand data retrieved via the communications
component 24 is collected in the memory 22 for each indoor unit 42a through 42f and 52a
through 52f. Based on the power demand data stored in the memory 22, the data processor
21 calculates the peak production time in which the overall power demand has peaked in the
air conditioners 4 and 5, and extracts the three indoor units 42c, 52e, and 52f in the order of
greatest power demand in the peak production time. The power demand data during the
peak production time for the three indoor units 42c, 52e, and 52f extracted by the data
processor 21 can also be graphed and displayed on the display component 23. The user is
also advised to suppress and control the power demand in the indoor units 42c, 52e, and 52f
extracted by the data processor 21.
The data processor 21 can thus extract the three indoor units 42c, 52e, and 52f which
have substantial indoor unit power demand in the peak production time and which are highly
likely to be have a significant effect on the overall power demand. The power demand data
of the extracted indoor units 42c, 52e, and 52f can also be graphed to notify the user. The
user can therefore be notified of the indoor units 42c, 52e, and 52f which are highly likely to
have a significant effect on the overall power demand, along with the operating data, leading
to countermeasures for reducing power consumption. The user can also be presented with
countermeasures for reducing power consumption, and not merely shown the operating data
of the indoor units 42c, 52e, and 52f which are highly likely to have a significant effect on the
overall power demand. This can therefore lead to effective countermeasures for reducing
power consumption, and can also alleviate the burden on the user.
(4)
In the present invention, power consumption data and outdoor temperature data
retrieved via the communications component 24 are associated and collected in the memory
22 as data on power consumption by outdoor temperature for the indoor units 42a through
42f and 52a through 52f. Based on the power consumption data by outdoor temperature
stored in the memory 22, the data processor 21 extracts three indoor units in order of the
greatest displacement in trends for each of the indoor units 42a through 42f and 52a through
52f based on the trends for all of the indoor units 42a through 42f and 52a through 52f. The
displacement revealed by comparison between, first, the operating data for the three indoor
units 42c, 42f, and 52e extracted by the data processor 21 and, second, the approximate line 1

showing the trends for all the indoor units is also graphed and displayed on the display
component. The user is advised, for example, to lower blinds to block externally radiated
heat or to lower the level of introduced outdoor air having a substantial load, so as to suppress
the external load in room A RM11, room C RM13, and room D RM21 in which the indoor
units 42c, 42f, and 52e extracted by the data processor 21 are set up.
The data processor 21 can thus extract the three indoor units 42c, 42f, and 52e which
are highly likely to be air conditioning rooms subject to substantial external load (room A
RM11, room C RM13, and room D RM21). The displacement revealed by comparison
between, first, the operating data for the extracted indoor units 42c, 42f, and 52e and, second,
the approximate line 1 can also be graphed to notify the user. The user can therefore be
notified of rooms which are highly likely to be subject to substantial external load (room A
RM11, room C RM13, and room D RM21), which can lead to countermeasures for reducing
power consumption. The user can also be presented with countermeasures for reducing
power consumption, and not merely shown the operating data of the indoor units 42c, 42f,
and 52e, which are highly likely to be air conditioning rooms that are subject to considerable
external load. This can therefore lead to effective countermeasures for reducing power
consumption, and can also alleviate the burden on the user.
(5)
In the present invention, power consumption data and outdoor temperature data
retrieved via the communications component 24 are associated and collected in the memory
22 as power consumption data by outdoor temperature for the indoor units 42a through 42f
and 52a through 52f. Based on the power consumption data by outdoor temperature
collected in the memory 22, the data processor 21 extracts three indoor units 42c, 42f, and
52e in order of the greatest displacement in trends for each of the indoor units 42a through
42f and 52a through 52f based on the trends for all of the indoor units 42a through 42f and
52a through 52f. The displacement revealed by comparison between, first, the approximate
lines ml through ml 2 representing the trends of each the three indoor units 42c, 42f, and 52e
extracted by the data processor 21 and, second, the approximate line 1 showing the trends for
all the indoor units is also graphed and displayed on the display component. The user is
advised, for example, to increase the outdoor intake level for room A RM11, room C RM13,
and room D RM21 in which the indoor units 42c, 42f, and 52e extracted by the data
processor 21 are set up.
The data processor 21 can thus extract the three indoor units 42c, 42f, and 52e,
which are highly likely to be air conditioning rooms subject to substantial internal load (room

A RM11, room C RM13, and room D RM21). The displacement revealed by comparison
between, first, the approximate lines mx representing the trends of each the three extracted
indoor units 42c, 42f, and 52e and, second, the approximate line 1 can also be graphed to
notify the user. The user can therefore be notified of rooms which are highly likely to be
subject to substantial internal load (room A RM11, room C RM13, and room D RM21),
which can lead to countermeasures for reducing power consumption. The user can also be
presented with countermeasures for reducing power consumption, and not merely shown the
operating data of the indoor units 42c, 42f, and 52e which are highly likely to be air
conditioning rooms that are subject to considerable internal load. This can therefore lead to
effective countermeasures for reducing power consumption, and can also alleviate the burden
on the user.
(6)
In the present invention, change data and changed time range data retrieved via the
communications component 24 are associated and collected in the memory 22 as change
frequency data by time range for the indoor units 42a through 42f and 52a through 52f.
Based on the change frequency data by time range collected in the memory 22, the data
processor 21 extracts three indoor units 42c, 42f, and 42a in the order of most frequent
overall changes in each of the indoor units 42a through 42f and 52a through 52f. The
change frequency data by time range for the three indoor units 42c, 42f, and 42a extracted by
the data processor 21 is also graphed and displayed on the display component 23. The user
is also advised to, for example, lower blinds to block externally radiated heat or to lower the
level of introduced outdoor air having a substantial load, so as to suppress the external load
on the indoor units 42c, 42f, and 42a extracted by the data processor 21.
The data processor 21 can thus extract the three indoor units 42c, 42f, and 42a in
which the sensory temperature and target temperature settings are highly likely to be not
matched. The change frequency data by time range for the extracted indoor units 42c, 42f,
and 42a can be graphed to notify the user. The user can therefore be notified of the indoor
units in which the sensory temperature and target temperature settings are highly likely to be
not matched, along with the operating data, leading to countermeasures for reducing power
consumption. The user can also be presented with countermeasures for reducing power
consumption. This can therefore lead to effective countermeasures for reducing power
consumption, and can also alleviate the burden on the user.
(7)
In the present invention, data on times when the thermostat is off, and outdoor

temperature data retrieved via the communications component 24, are associated and stored
in the memory 22 as data on times when the thermostat is off by outdoor temperature for each
of the indoor units 42a through 42f and 52a through 52f. Based on the data on times when
the thermostat is off by outdoor temperature stored in the memory 22, the data processor 21
displays the results in the order of rooms with the greatest number of units for which the
thermostat is off by outdoor temperature. The number of indoor units is also automatically
controlled by the control component 27 according to the outdoor temperature.
The data processor 21 can thus extract the indoor units of rooms in which the
thermostat is off for a long time and in which only air is highly likely to be blowing
wastefully. The number of operating indoor units 42a through 42c in the extracted room
(room A RM11) can be controlled and indoor units which are highly likely to be only blowing
air wastefully can be stopped. This can therefore lead to effective countermeasures for
reducing power consumption, and can also alleviate the burden on the user.
Modifications
Embodiments of the present invention were described on the basis of drawings, but
the specific structure is not limited to these embodiments and can be modified within scope
that does not depart from the spirit of the invention.
(1)
In the present embodiment, the air conditioners 4 and 5 were provided in a
three-story building, but buildings in which the air conditioners 4 and 5 may be provided are
not limited to three stories. The air conditioner monitor/support system 1 is also not limited
to three air conditioning systems that can be monitored, but may be used for four systems,
five systems, or the like.
(2) In the wasteful operation elimination mode according to the present embodiment,
the selected objects were the indoor units 42a through 42f and 52a through 52f of
considerable power consumption, in which the air conditioning temperature setting was
below 28°C during cooling operation, but the air conditioning temperature setting is not
limited to a temperature below 28°C, and may, for example, be a temperature below 27°C or
below 29°C.
(3)
In the mode for optimizing the number of operating units according to the present
embodiment, the countermeasure button 87 in the lower right of the screen SC17 for
optimizing the number of operating units is pressed to optimize the number of operating
indoor units of rooms that have been extracted in the results of analysis, but the invention is

not limited to this option alone, and the countermeasure button 87 in the lower right of the
screen SC17 for optimizing the number of operating units may be pressed to display a
countermeasure screen SC27 for optimizing the number of operating units (see FIG. 20).
Here, the countermeasure screen SC27 for optimizing the number of operating units
displays a message: "The number of thermostats that are off in room A has increased. It is
recommended that the operation of the indoor units in room A be stopped." This will allow
the user to take specific measures to reduce power consumption in response to the above
results of analysis. The menu button 97 in the lower right of the countermeasure screen
SC27 for optimizing the number of operating units is pressed to return to the countermeasure
mode selection screen SC1.
