Q4. A refrigerator uses fereon-12 as the working fluid operates in a vapor-compression refrigeration cycle between 0.12 and 0.7 MPa. The mass flow rate of the refrigerant is 0.1 kg/s. Show the cycle on T-S diagram. Determine: a. The rate of heat removal from the refrigerated space. b. The power input to the compressor. The rate of heat rejected to the environment. c. The coefficient of performance. Ans: Q.=10.76 Btu/s, W= -2.91 Btu/s, COP=3.69
