In a vapor-compression refrigeration cycle, ammonia exits the evaporator as saturated vapor at -10°C. The refrigerant enters the condenser at 16 bar and 160°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. If the refrigerating capacity is 150 kW, determine (a) the mass flow rate of refrigerant, in kg/s (b) the power input to the compressor, in kw (c) the coefficient of performance (d) the isentropic compressor efficiency Round answers to 3 significant digits. (a) 0,1444 (b) 52.99 (c) 2.83 (d) 88.26
