A refrigerant 22 vapor compression system includes a liquid-to-suction heat exchanger in the system. The heat exchanger cools the saturated liquid from the condenser from 32°C to 21°C with vapor which comes from the evaporator at -10°C. The compressor is capable of pumping 20 L/sec of refrigerant. What is the enthalpy of the refrigerant at the suction of the compressor neglecting the heat exchanger? What is the isenthalpic value of the refrigerant in the system neglecting the heat exchanger? What is the refrigerant's enthalpy after compression? What is the COP of the system neglecting the heat exchanger? What is the enthalpy of the refrigerant before it enters in the expansion valve? What is the approximate enthalpy of the refrigerant at the suction of the compressor? What is the estimated enthalpy of the refrigerant after compression? What is the COP of the system? What is the refrigerating capacity of the system in TOR if: a.) without hex and b.) with hex?
