A steady-flow Carnot refrigeration cycle uses refrigerant-134a as the working fluid. The refrigerant changes from saturated vapor to saturated liquid at 60°C in the condenser as it rejects heat. The evaporator pressure is 180 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

(c) The net work input.
