In a 15 TR ammonia refrigeration plant, the condensing temperature is 25°C and evaporating temperature -10°C. The refrigerant ammonia is sub cooled by 5°C before entering through the throttle valve. The vapor leaving the evaporator is 0.97 dry. Using P-h Chart, Determine: (a) Refrigerating effect (b) COP (c) Power required C 0.97 dry Condenser 25°C Sub cooled by 5°C Evaporator 15TR, -10°C EV In a 15 TR ammonia refrigeration plant, the condensing temperature is 25°C and evaporating temperature -10°C.
