A refrigerant 22 vapor-compression system includes a liquid-to-suction heat exchanger in the system. The heat saturated vapor exchanger warms saturated coming from the evaporator from - 10 degrees * C to 5 degrees * C with liquid which comes from the condenser at 30 degrees * C . The compression is isentropic in both cases listed below. (a) Calculate the coefficient of performance of the system without the heat exchanger but with the condensing temperature at 30 degrees * C and evaporating temperature of - 10 degrees * C . (b) Calculate the coefficient of performance 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 the 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?
