The next four (4) problems apply to a vapor compression refrigeration cycle that utilizes ammonia as the refrigerant. The saturated evaporator temperature is -10F and the saturated condenser temperature is 95F. Saturated vapor exits the evaporator and saturated liquid exits the condenser. The mass flow rate of the refrigerant in the cycle is 300 lbm/hr.
