A heat engine is used to run a refrigerator. The thermal efficiency of the machine is 0.30 and the coefficient of operation of the refrigerator is 4. Determine the heat input needed in the machine for each Btu removed from the cold compartment of the refrigerator
Added by Ismael J.
Step 1
The thermal efficiency of a heat engine is given by the formula: thermal efficiency = (work output / heat input) In this case, the thermal efficiency is given as 0.30. Therefore, we can write: 0.30 = (work output / heat input) Show more…

A kitchen refrigerator is to maintain a temperature of -15 °C inside the refrigerator. Temperature in the kitchen is 26 °C. The coefficient of performance for the refrigerator is said to be 40 % of an ideal Carnot refrigerator operating between these temperatures. If the amount of heat that needs to be removed from the refrigerator 10,000 kJ /h to sustain -15 °C inside the refrigerator, calculate the power input to the compressor.

The food compartment of a refrigerator, is maintained at 4°C by removing heat from it at a rate of 360 kJ/min. If the required power input to the refrigerator is 2 kW, determine (a) the coefficient of performance of the refrigerator and (b) the rate of heat rejection to the room that houses the refrigerator.
