225. In an ammonia refrigeration system, the temperature in the evaporator is -12°C and the

ammonia at the evaporator entry 0.1511 dry while at exit is 0.95 dry. If the rate of ammonia

circulation is 5.64 kg/min, determine the refrigerating capacity of the system. Enthalpy of

saturated liquid and vapor at -12°C is 144.929 kJ/kg and 1447.74 kJ/kg respectively.
