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