The 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. Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP … See more According to the first law of thermodynamics, after a full cycle of the process $${\displaystyle Q_{\rm {H}}+Q_{\rm {C}}+W=\Delta _{\rm {cycle}}U=0}$$ and thus See more A realistic indication of energy efficiency over an entire year can be achieved by using seasonal COP or seasonal coefficient of … See more 1. ^ "Archived copy" (PDF).
