In a 5 kW cooling capacity refrigeration system operating on a simple vapour compression cycle, the refrigerant enters the evaporator with an enthalpy of 75 kJ/kg and leaves with an enthalpy of 183 kJ/kg. The enthalpy of the refrigerant after compression is 210 kJ/kg. show the cycle on T-s or P-h diagram. Calculate the following:
(a) COP
(b) Power input to compressor and
(c) Rate of heat transfer at the condenser
