How should we define the â€œ*efficiency*â€ of a *refrigerator*? Again the relevant. is W. To avoid confusion with *equation* 4.1, this ratio is called the coefficient of.

The above *equation* is multiplied by 100 to express the *efficiency* as percent. French Engineer Sadi Carnot showed that the ratio of QHighT to QLowT must be

The vapor compression *refrigeration* cycle is a common method for transferring heat from a. number or seasonal adjusted energy *efficiency* ratio. The SEER is

In this mode of operation the cycle works as a *refrigerator* or heat pump.. What is the same whatever the medium is the *efficiency* for all Carnot cycles operating
