Estimate some reasonable temperatures to use and find all the fluxes of exergy in the refrigerator in Example 5.2.

Example 5.2

The refrigerator in a kitchen shown in Fig. receives electrical input power of 150 W to drive the system, and it rejects 400 W to the kitchen air. Find the rate of energy taken out of the cold space and the COP of the refrigerator.
