[Thermo Hw Help] I need some help with this thermo problem EngineeringStudents


The refrigerator operates at steadystate with a coefficient of performance of 5.0 within a kitchen at 23 C. The refrigerator rejects 4.8 kW by heat transfer to its surroundings from metal coils located on its exterior.


Determine (a) the power input, in kW. (b) the lowest theoretical temperature inside the refrigerator, in K.


The answers are, (a). W_dotcycle = 0.8kW (b). The minimum theoretical temperature is 246.7K


Any clues on how to start this?
