A vapor-compression refrigeration system operates on the cycle of Fig. 9.1. The refrigerant is water. Given that the evaporation T/t = 277.15 W 4"C, the condensation T/t = 307.15 K/34"C, (compressor) = 0.76, and the refrigeration rate = 1200 kW, determine the circulation rate of the refrigerant, the heat-transfer rate in the condenser, the power requirement, the coefficient of performance of the cycle, and the coefficient of performance of a Carnot refrigeration cycle operating between the same temperature levels.
