a refrigerant R-22 vapour compression system includes a liquid to suction heat exchanger in the system. The heat exchanger warms saturated vapour coming from evaporator from (-10 °C) to 5 °C with liquid which comes from the condenser at 30°C. the compression are isentropic in both cases below. A - calculate the COP of the system without the heat exchanger but with condensing temperature at 30°C and evaporator temperature of (-10°C)(5.46) b- calculate the COP with the heat exchanger (5.37) c- if the compressor is capable of pumping 12 lit/s measured at the compressor suction, what is the refrigeration capacity of the system without heat exchanger and with heat Crchanger(30 3KW. 29.9kW)
