A vapor-compression refrigeration system operates on the cycle shown below. The refrigerant is tetrafluoroethane. For the following set of operating conditions, 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 table containing the properties of saturated 1,1,1,2-tetrafluoroethane (R134A) and the PH diagram for tetrafluoroethane (HFC-134a). (Include a minus sign if required.) Vapor-compression refrigeration cycle. Evaporation T=12C Condensation T=26C (compressor) =0.77 Refrigeration rate =400kJ.s1 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
