1. A refrigeration system utilizes R-134a and operates on an ideal refrigeration cycle. The refrigerant enters the compressor at 140 kPa and leaves it at 800 kPa and the refrigeration rate is evaluated to 300 kJ/min. Show the cycle on a T-s diagram with respect to saturation lines, and determine: (a) The refrigerant quality at the throttling outlet (b) The power required in the compressor (e) The coefficient of performance
