Coefficient of Performance
The efficiency of a refrigerator or heat pump is given by a parameter called the coefficient of performance (COP).
The COP of a refrigerator is given by the following equation:
- COP = QL/Wnet,in
For an ideal cycle:
- COP = TL/(TH-TL)
The COP of a heat pump is given by the following equation:
- COP = QH/Wnet,in
For an ideal cycle:
- COP = TL/(TL-TH)

Famous quotes containing the word performance:
“True balance requires assigning realistic performance expectations to each of our roles. True balance requires us to acknowledge that our performance in some areas is more important than in others. True balance demands that we determine what accomplishments give us honest satisfaction as well as what failures cause us intolerable grief.”
—Melinda M. Marshall (20th century)
