Abstract
The proposed calculation takes into account the peculiarities of the operation of the heat pump as part of the surface foundation on permafrost soils, i.e., the heat flow from the heating circuit of the pump to the cooling circuit. Heat transfer reduces the conversion coefficient of low-potential heat into high-potential heat, but, unfortunately, this is ignored in well-known publications. In addition, the calculation shows a significant effect of the freon brand in the evaporation-condensation circuit of the refrigeration machine on the conversion coefficient.
