The cold storage is to be maintained between 2C to 4C to preserve the processed fruit products and the cooling cycle of the pasteurization process is also operated between 2C to 4C. It is recommended that a ZB series Scroll type compressor manufactured by Emerson Climate Technologies should be used for the refrigeration system and the compressor has an isentropic efficiency of (75+0.5**x+0.3**Y)%. The meximum compressor delivery pressure should be limited to 1200 kPa (absolute). For this delivery pressure the recommended condenser heat exchanger will have a maximum fluid frictional pressure loss of (22- Y) kPG.(Note: A liquid-cooled plate heat exchanger ia to be used for the condenser). It is recommended to use refrigerant R134a for this system. The refrigerant will be cooled (3.8+0.2**y. C below its saturation temperature by the time it leaves the condenser. The refrigerant leaves the evaporator at a pressure of 240 kPa (absolute) and temperature of (5.8-0.2***x) CC above its saturation temperature. The pressure drop in the evaporator is (18+vvv)kPa. The water demand varies throughout the day and is provided in excel file as a function of x and Y along with the rate of cooling demand for cold storage and pasteurization. x=7,Y=8.
