A steady-flow Carnot refrigeration cycle uses refrigerant-

134a as the working fluid. The refrigerant changes from

saturated vapor to saturated liquid at 608C 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, and (c) the net

work input.
