WebIf we concentrate just on the compressor as a heat pump, we can make some simple assumptions about the COP (coefficient of performance) of the compressor to come up … 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 performance (SCOP) for heat. Seasonal energy efficiency ratio (SEER) is mostly used for air conditioning. SCOP is a new … See more 1. ^ "Archived copy" (PDF). Archived from the original (PDF) on 2013-01-24.
