The environmentally safe refrigerant R-152a is to be evaluated as the working fluid for a heat pump system that will heat a house. It uses an evaporator temperature of –20oC and a condensing temperature of 30oC. Assume all processes are ideal and R-152a has a heat capacity of Cp = 0.996 kJ/kg K. Determine the cycle coefficient of performance.
