Do Problem 8.34 using refrigerant R-134a instead of R-22. Consider a Carnot-cycle heat pump with R-22 as the working fluid. Heat is rejected from the R-22 at 40°C, during which process the R-22 changes from saturated vapor to saturated liquid. The heat is transferred to the R-22 at 0°C.
a. Show the cycle on a T–s diagram.
b. Find the quality of the R-22 at the beginning and end of the isothermal heat addition process at 0°C.
c. Determine the coefficient of performance for the cycle.
