REFRIGERATION ENGINEERING
USE SHAPIRO AND MORAN STEAM TABLES
The refrigeration system of a food production firm is run using the Reversed Carnot Cycle. The temperature of the hot refrigerant supply in the system should be 52°C, while the temperature of the sink should be -14°C. Its capacity is projected to be at least 24 tons. It's important not to disregard losses.

- 3.5 An ammonia refrigeration system operates between saturated suction temperature of -20°C, and saturated discharge temperature of +40°C. Com- pare the COP of the cycle using wet compression with that of the cycle using dry compression. Assume that the vapour leaving the compressor is saturated in the case of wet compression, and the vapour entering the compressor is saturated in the case of dry compression. The refrigerant leaves the condenser as saturated liquid.arrow_forwardExampie Air conditioning unit uses Freon R-22 for conditioned office at 25 C.
