Problem 1 Refrigerant 134-a enters the compressor of a refrigerator at 180 kPa and -5 °C at a rate of 0.4 m3/min and is compressed isentropically to 850 kPa. The refrigerant enters the throttling valve at 800 kPa and 30 °C and leaves the evaporator as saturated vapor at -12 °C. Note: Need to determine mass flow rate. Determine: • Power input to the compressor • The rate of heat removal from the refrigerated space • Plot the rate of heat removal against compressor power for flow rates varying from 0.2 m3/min to 1 m3/min under inlet pressures 100,150 and 200 Kpa. • Using EES, plot the P-h diagram for flow rate of 0.4 m3/min.
