Question-3As seen in the figure, the stable air conditioner keeps the indoor environment at 21oC while the outdoor environment is 32oC. Since the heat transfer rate from the roof and walls to the house is 31,650 kJ/h, is the 2.2 kW power input to the compressor of the air conditioner sufficient? If sufficient, calculate COP, if not, find the theoretical minimum power in kW
Thank you
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.
