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.
