A steady-flow Carnot refrigeration cycle uses refrigerant-134a as the working fluid. The refrigerant changes from saturated vapor to saturated liquid at 30oC in the condenser as it rejects heat. The evaporator pressure is 120 kPa.
(a) Show the cycle on a T-s diagram relative to saturation lines, determine
(b) The amount of heat absorbed from the refrigerated space per kg of flow (qC) and
(c) The coefficient of performance (COPR),
(d) The net work input per kg of flow (wnet).
