A vapor-compression refrigeration system operates on the cycle shown below. The refrigerant is water. Given that the evaporation T is 4C, the condensation T is 34C, (compressor) is 0.76 , and the refrigeration rate is 1200kJs1, 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. Use the steam tables. (Include a minus sign if required.) Vapor-compression refrigeration cycle. The circulation rate of the refrigerant is kgs1. The heat-transfer rate in the condenser is kJs1. The power requirement is kW. The coefficient of performance of the cycle is The coefficient of performance of a Carnot refrigeration cycle operating between the same temperature levels is
