10.10 An ideal vapor-compression refrigeration cycle with ammonia as the working fluid has an evaporator temperature of −20°C and a condenser pressure of 12 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
