In a standard vapour compression refrigeration cycle, operating between an evaporator temperature of -18°C and a condenser temperature of 36°C, the enthalpy of the refrigerant, Freon-12, at the end of compression is 225 kJ/kg. on T-s plane. Show the cycle diagram in the PV and TS diagram; Calculate: (ii) The C.O.P. of the cycle; (iii) The refrigerating capacity; (iv) The compressor power assuming a refrigerant flow rate of 1 kg/min.
