Consider a 300 kJ/min refrigeration system that operates on an ideal vapor-compression refrigeration cycle with R-134a as the working fluid. The refrigerant enters the compressor as saturated vapor at 140 kPa and is compressed to 800 kPa. Show the cycle on a T-s diagram with respect to saturation lines and determine (a) the quality of the refrigerant at the end of the throttling process, (b) coefficient of performance, (c) the power input to the compressor , (d) Generation of entropy for the entire cycle.
