WebJan 29, 2024 · Air source heat pumps tend to be less efficient, and a COP over 3 is considered good. Comparing different air source heat pumps, it is worth bearing in mind that a heat pump with a higher CoP / SPF will cost more, and the same is true when comparing ground source heat pumps with one another. Difference Between COP and Efficiency. WebAug 14, 2024 · 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. Click to see full answer.
WebA high COP value represents a high efficiency. Most of the electric energy needed to drive the compressor is released to the refrigerant as heat. Therefore more heat is available at the condensor than is extracted at the evaporator of the heat pump. For a heat pump a COP value of 4 means that the addition of 1 kW of electric energy is needed to ...
