A steady-flow Carnot refrigeration cycle uses refrigerant-134a as the working fluid.
The refrigerant changes from saturated vapor to saturated liquid at 30°C in the condenser as it
rejects heat. The evaporator pressure is 160 kPa. Show the cycle on a T-s diagram relative to
saturation lines, and determine (a) the coefficient of performance, (b) the amount of heat
absorbed from the refrigerated space, and (c) the net work input.
