A refrigerator uses refrigerant-134a as the working fluid and operates on an ideal vapor-compression cycle between 0.12 and 0.7 MPa. The mass flow rate of the refrigerant is 0.05 kg/s. Show the cycle on a T-s diagram. Determine: a. The rate of heat removal from the refrigerated space. b. The power input to the compressor. c. The rate of heat rejection to the environment. d. The COPR. e. The COPR of a Carnot refrigeration cycle operating between Tsat(0.12MPa) and Tsat(0.7MPa) for R-134a.
