Saturated vapor ammonia at -16°C (h = 1442.60 kJ/kg) leaves the evaporator and
enters the compressor at -6°C (h = 1465 kJ/kg). The refrigerant leaves the condenser as
saturated liquid at 40°C (h = 390.6 kJ/kg) and enters the expansion valve at 35°C (h =
366.1 kJ/kg). Heat rejected from the condenser amount to 50 kW. The work to compressor is
208 kJ/kg, while the heat loss from compressor is 33 kJ/kg. If 95 kJ/kg of heat are lost in the
piping between the compressor discharge and condenser inlet, determine the refrigerating
capacity of the system.
