Arefrigerator using refrigerant-134a as the working fluid operates on the vapor compression cycle. the cycle operates between 200 kpa and 1.2 mpa. the refrigerant flows through the cycle at a rate of 0.023 kg/s. the (actual) refrigerator has a compressor with an isentropic efficiency of 87%. the refrigerant enters the compressor slightly superheated by 7.6∘∘c (hint: add this to the saturation temperature). the refrigerant leaves the condenser slightly subcooled by 1°c. a)-what is the rate of heat removal from the refrigerated space for the actual refrigerator in kw? (b)- what is the power supplied to the compressor for the actual refrigerator in kw? c)-what is the cop for the actual refrigerator?
