WebThe coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [1] [2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.

http://www.physicsbootcamp.org/The-Carnot-Refrigerator.html The merit of a refrigerator or heat pump is given by a parameter called the coefficient of performance (COP). The equation is: where • is the useful heat given off or taken up by the considered system. • is the net work done on the considered system in one cycle.

WebThe effectiveness or coefficient of performance K R of a refrigerator is measured by the heat removed from the cold reservoir divided by the work done by the working substance cycle by cycle: K R = Q c W = Q c Q h − Q c. 4.3.
