Consider a carnot refrigeration cycle with a working fluid, Ask an Expert

Academics

Consider a Carnot Refrigeration cycle with a working fluid of R-134a operating between temperatures of -10^oC and 20^oC. The compressor in the cycle requires 500 W of power.

a) What is the maximum coefficient of performance?

b) What is the rate of heat that is removed from the refrigerated space?

c) What is the rate of heat that is rejected from the cycle?

d) The R-134a enters the evaporator as a saturated mixture with a quality of 0.1. If the R-134a leaves the evaporator as a saturated mixture with a quality of 0.9 what is the flow rate?
