Refrigerant-134-a undergoes an actual vapor-compression cycle. The refrigerant enters the compressor at at 140 kPa at -10°C with a volumetric flow rate of 0.75 m³/min and leaves at 900 kPa. The refrigerant enters the throttling value at 0.85 MPa and 32°C and leaves the evaporator at -20°C as a saturated vapor. Assume that the compressor has an isentropic efficiency of 95%.
