A steady, ideal vapor-compression refrigeration cycle uses R134a as the refrigerant. The evaporator pressure is 200 kPa while the condenser pressure is 2000 kPa. The heat source for the cycle is at a temperature of -90C while the temperature of the heat sink is 27 0C. The rate of heat rejected in the condenser is 18.0 kW. Find the volume flow rate at the compressor inlet [L/s], the power input [kW], the COP, the second-law efficiency and the total exergy destruction rate [kW].
