Saturated vapor Freon 12 refrigerant at 219.12 kPa leaves the evaporator and enters the compressor at -5 °C. The refrigerant leaves the condenser as saturated liquid at 25°C and enters the ex pansion valve at 22°C. Heat rejected from the condenser amount to 75 kW. The work to the compressor is 55.5 kJ/kg, while the heat lost from the compressor is 4.2 kJ/kg. If 1.15 kJ/kg of heat are lost in the piping between the compressor and condenser, cal culate the refrigeration capacity in tons.
