A refrigerator using R-410a is powered by a small natural gas-fired heat engine with a thermal efficiency
Question:
A refrigerator using R-410a is powered by a small natural gas-fired heat engine with a thermal efficiency of 25%, as shown in Fig. P9.110. The R-410a condenses at 40◦C and evaporates at −20◦C, and the cycle is standard. Find the two specific heat transfers in the refrigeration cycle. What is the overall COP as QL/Q1?
