In a vapor-compression refrigeration cycle, 9 kg/min of ammonia exits the evaporator as saturated vapor at-12°C. The refrigerant enters the condenser at 16 bar and 140°C, and saturated liquid exits at 16 bar. There is no significant heat transfer between the compressor and its surroundings, and the refrigerant passes through the evaporator with a negligible change in pressure. Determine the refrigerating capacity, in kW. kW %3D
