  • Page 7: Coefficient Of Perfomance

    2.3. Coefficient of perfomance Heat pump efficiency ratio is measured with coefficient of performance, COP. COP indicates the amount of heat energy transferred into compressor in relation to used electrical energy. COP depends largely on heat source and heating network temperatures. The highest possible heat source temperature and the lowest possible supply water temperature improve efficiency ratio.
