WATER CHILLER
The invention relates to Integral Water Chiller for Ice Making.
The invention relates to Integral Water chiller, more particularly the invention relates to the Integral water Chiller wherein the water is at ambient temperatures and is passed around a columns of tubes in the form of the fine film of water from top to bottom wherein referigerents are passed through out side the tubes so as to transfer the heat and thereby cooling the film of water dropping down to 5-10° C and thereby the effective heat transfers will ultimately help fastering making
The integral Water Chiller is installed in the ice maker in between the refrigeration evaporator and the accumulator so that the refrigerant liquid and vapour discharge pipe will cool the water film inside the minute tubes; so the drop of temperatures results each tube is having one no. of distributor tubes through which the water will flow from top to bottom.
The primary object of this invention is to provide an Integral Water Chiller for faster cooling of water by providing multiplicity of tubes vertically placed through which film of water drops down while refrigerant vapour discharge is flowing around the tubes, thereby cooling water inside the tube to 5-10° C which is discharged at the bottom.
Another object of this invention is to install the said Integral water Chiller in between the freezing surface of the Ice-Maker and the accumulator, thereby making of ice faster.
Accordingly there is provided an Integral Water Chiller comprising plurality of tubes packed in a chamber separated by tube sheets for flowing water of ambient


temperatures from top to bottom wherein each tubes comprises of multiplicity of distributor tubes through which film of water drops, wherein refrigerant vapour discharged is flowing around the tubes; thereby cooling the water inside the tube to 5-10°C which is discharged at the bottom.
The invention will now be described with reference to fig.l to fig.4 in the accompanying drawings.
Fig.l: Is a sectional view of icemaker with Integral Water Chiller.
Fig.2: Is a plan view of ice-maker with integrated water chiller.
Fig.3: Is a sectional elevation of integral water chiller.
Fig.4: Is plan view of the individual tubes.
Referring to fig.l to 4; The Integral Water Chiller (1) comprises of a outer shell (2) accommodating a multiplicity of tubes (3) said tubes are placed vertically separated by tube sheets (4); around which refrigerant vapour discharge (5) is passing for cooling; the water of 30° C. Passes through the inlet (6) of the Integral Water Chiller and drops down at the outlet (7); the said fine tubes (3) having thin film of water about 600 - 1000 millimeters tube length pulls down and discharge at the outlet; there is provided a water receiver (8) at the bottom with overflow vent (9) for removing excess of water.
The above Integral Water Chiller is placed in between the refrigeration surface (10) and the accumulator cover (11) of the ice-maker, so that the formation of ice becomes faster.


Instead of supplying water 30° C the icemaker with Integral Water Chiller will supply now the water at 5-10° C thereby making ice become faster due to pre-cooling.
The ice maker wherein the water is pumped at 30°C to the water chiller and the water emerges through water chiller at 5-10°C is pumped in the Ice-maker for making ice faster. The Integral Water Chiller in Fig.3 comprises of the number of water distribution tubes of 600 - 1000 millimeters in length which are packed side by side, separated by tube sheet. The water is supplied from the top and the water film drops down to the bottom through the refrigerant vapour discharge, thereby cooling the water inside the tube, due to heat transfer. The water at the discharge end is cooled to 5-10°C. According to multiplicity of distributor tubes through which the water will flow arranged in a tube through which refrigerant vapour flows.
1. Water is sprayed on freezing surface with the help of water pipettes on inside the evaporator drum cools water and freezes water to form ice on freezing surface.
2. Mixture of vapour and liquid of evaporated refrigerant emerges out of evaporator jacket and goes to accumulator through VD i.e vapour discharge outlet and passage in water chiller shell side.
3. The vapour and liquid are separated in accumulator and vapour is sucked by compressor.
4. The liquid returns back to evaporator jacket through LI (Liquid Inlet) and liquid passage in water chiller shell side.
5. The refrigerant level in jacket allows refrigerant to develop similar level in water chiller and provide refrigeration to chill water flowing through the tubes.
6. Water is put inside tubes with the help of water distributors. The water film cools and evaporates refrigerant on shell side of chiller and vapour goes along with vapour from ice maker to suction of compressor.

7. Water from ambient temperature cools to required temperatures i.e. between 5-10°C for further cooling in ice maker drum.
8. In effect the cooling area of water chiller prorata increases the capacity of making ice.
This is an embodiment of the invention. Several modifications are possible may be considered within the ambit and spirit of this invention. Since many modifications, variations and changes in detail may be made to the above described embodiments, it is intended that all matters described in the foregoing description as described in the accompanying specification.

I Claim:
1. Integral Water Chiller for Ice making comprising plurality of tubes
packed in a chamber separated by tube sheets for flowing water of ambient temperatures from top to bottom wherein each tube comprises of multiplicity of fine tubes through which film of water drops, wherein refrigerant vapour discharged from Ice maker is flowing around the tubes; thereby cooling the water inside the tube to 5°C to 10°C which is discharged at the bottom and conveyed to the freezing surface of the Ice Making.
