Refrigerant R-134a enters the condenser of a steady-flow Carnot refrigerator as a saturated vapor at 100 psia, and it leaves as saturated liquid. The heat absorption from the refrigerated space takes place at a pressure of 30 psia and the mass flow rate is 1 kg/s.
(a) Show the cycle on a T-s diagram relative to saturation lines, determine
(c) The quality at the beginning of the heat-absorption process and
(b) The coefficient of performance (COPR),
(d) The net work input.
