In a standard vapour compression refrigeration cycle, operating between an evaporator temperature of 100 C, the enthalpy o the refrigerant. Freon -12 at the end of compression is 220 kG/kg. show the cycle diagram on T-s plane . Calculate (a) the COP of the cycle (b) the refrigerating capacity and the compressor power assuming a refrigerant flow rate of 1 kg/min. You may extract of the Freon – 12 property table given below.
