In a 14 TR ammonia refrigeration plant, the condensing temperature is 250C and evaporating temperature -100C. The refrigerant ammonia is sub-cooled by 5 0C before passing through the throttle valve. The vapor leaving the evaporator is 0.97 dry. Find: 1. Coefficient of performance: and 2. Power required. Use refrigerant table for properties of ammonia at 250C and -100C.
