A commercial refrigerant that uses R-134a as the refrigerant is used for cooling, to keep the condition at -35o, throws heat into the cooling water that has been in the condenser at 18oC and 0.25kg / s and has been formed since 26o. The refrigerant enters the condenser at 1.2 MPa and 50o ° and exits by cooling 5o C more than the saturation temperature at the same pressure. If the compressor consumes 3.3 kW (Answer: 0.0498 kg / s, 5.07 kW, 1.54, 1.13 kW) a) mass flow rate of refrigerant b) cooling load (amount of usage amount of heat) c) COP d) required for the same cooling load tr detect small compressor power
