An ideal vapor-compression refrigeration cycle with ammonia as the working fluid has an evaporator temperature of -30°C and a condenser pressure of 10 bar. Saturated vapor enters the compressor and saturated liquid exits the condenser. The mass flow rate of the refrigerant is 3 kg/min. Determine: (a) the coefficient of performance. (b) the refrigerating capacity, in tons.
