Question: A steady-flow Carnot refrigeration cycle uses refrigerant-134a as the working fluid. The refrigerant changes from saturated vapor to saturated liquid at 60oC in the condenser

A steady-flow Carnot refrigeration cycle uses refrigerant-134a as the working fluid. The refrigerant changes from saturated vapor to saturated liquid at 60oC in the condenser as it rejects heat. The evaporator pressure is 140 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.
