Co-efficient of Performance (COP) of a refrigerator is the ratio of the ______________________?
Correct answer: B. Refrigeration obtained to the work required
- A. Work required to refrigeration obtained
- B. Refrigeration obtained to the work required
- C. Lower to higher temperature
- D. Higher to lower temperature
Explanation
Refrigerator performance is measured by the cooling effect obtained divided by the work supplied: COP = refrigeration effect / work input. A higher COP means more cooling for each unit of work.
