Determine the influence of the evaporator temperature on the heat pump coefficient of performance for an ideal

Question:

Determine the influence of the evaporator temperature on the heat pump coefficient of performance for an ideal vapor-compression cycle. The working fluid is R-22. The pressure is fixed in the condenser at 1.342MPa. Vary the evaporator temperature over a reasonable range that includes Tsat =  0:653MPa), the condition specified in Problem 9.122. Discuss your results.image



Problem 9.22


Determine the heat pump coefficient of performance for an ideal vapor compression refrigeration cycle operating between 0.653 and 1.342 MPa. The working fluid is R-22. Compare your result with that for the real cycle described in Example 9.14.
