A Carnot-cycle refrigerator rejects heat at the pressure of 1000kPa during which the working fluid R -134a changes from saturatedvapor to saturated liquid. The heat is added to the cycle at thepressure of 320 kPa. Show the cycle in a T-s diagram and determinethe coefficient of performance of the cycle using a) the first lawof thermodynamics b) the Carnot cycle efficiency equation and c)the T-s diagram.
