A Carnot vapor refrigeration cycle uses R-134a as the working fluid. The 2 poin refrigerant enters the condenser as saturated vapor at 28°C and leaves as saturated liquid. The evaporator operates at a temperature of -10°C. For every kg of refrigerant flow, calculate the coefficient of performance of the cycle.
