Cop for several heat pumps
WebThe Coefficient of Performance - COP - is the ratio of heat output to the amount of energy input for a heat pump. COP can be expressed as. COP = hh / hw (1) where. COP = Coefficient of Performance. hh = heat … 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 usually exceeds 1, especially in heat pumps, because, instead of just converting wor…
