Do Problem 6.197E using refrigerant R-134a instead of R-410a.
Problem 6.197E
Consider a Carnot-cycle heat pump with R-410a as the working fluid. Heat is rejected from the R-410a at 110 F, during which process the R-410a changes from saturated vapor to saturated liquid. The heat is transferred to the R-410a at 30 F.
a. Show the cycle on a T-s diagram.
b. Find the quality of the R-410a at the beginning and end of the isothermal heat addition process at 30 F.
c. Determine the COP for the cycle.
