Consider a 500 kJ/min refrigeration system that operates on an ideal vapor-compression refrigeration cycle with refrigerant-134a as the working fluid. The refrigerant enters the compressor as saturated vapor at 150 kPa and is compressed to 800 kPa.
(a) Show the cycle on a T-s diagram with respect to saturation lines, and determine
(b) The quality of the refrigerant at the end of the throttling process,
(c) The coefficient of performance (COPR) and
(d) The work input per unit mass of flow (wnet) to the compressor.
