    An ideal vapor-compression refrigeration cycle, with ammonia as the working fluid, has an evaporator temperature of -20c 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:

    - The coefficient of performance
    - The refrigerating capacity, in tons
