A refrigerant 22 vapor compression system includes a liquid-to-suction heat exchanger in the system. The heat exchanger warms saturated vapor coming from the evaporator from -10 to 5 with a liquid which comes from the condenser at 30. The compressions are isentropic in both cases listed below. a. Calculate the coefficient of performance of the system without the heat exchanger but with a condensing temperature at 30 and an evaporating temperature of -10 b. Calculate the COP of the system with the heat exchanger c. If the compressor is capable of pumping 12.0 L/s measured at the compressor suction, what is he refrigeration capacity of the system without the heat exchanger? d. With the same compressor capacity as in (c), what is the refrigeration capacity of the system with the heat exchanger?
