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.
