Refrigerant enters the compressor of a refrigerator at (P-100,110,120,130,140,150.160,170,180,190,200) kPa and -10C at a rate of 0.3 m/min and leaves at 1 MPa. The isentropic efficiency of the compressor is 78%. The refrigerant enters the throttling valve at 0.95 MPa and 30C and leaves the evaporator as saturated vapor at 18.5C. Show the cycles on P-h diagram with respect saturation lines, for R134a, R22, and R12, determine: The power input to the compressor, b. The rate of heat removal from the refrigerated space. c. The pressure drops and rate of heat gain in the line between the evaporator and compressor, and d. Plot the COP for various refrigerant and discuss your results,
