Consider a steady-flow Carnot refrigeration cycle that uses refrigerant-134a as the working fluid. The maximum and minimum temperatures in the cycle are 30 and -20C, respectively. The quality of the refrigerant is 0.15 at the beginning of the heat absorption process and 0.80 at the end. Show the cycle on a T-s diagram relative to saturation lines, and determine (a) the coefficient of performance, (b) the condenser and evaporator pressures, and (c) the net work input.

Question
Consider a steady-flow Carnot refrigeration cycle
that uses refrigerant-134a as the working fluid. The maximum
and minimum temperatures in the cycle are 30 and -20C,
respectively. The quality of the refrigerant is 0.15 at the beginning
of the heat absorption process and 0.80 at the end. Show
the cycle on a T-s diagram relative to saturation lines, and
determine (a) the coefficient of performance, (b) the condenser
and evaporator pressures, and (c) the net work input.
