The proposed calculation takes into account specific features of the operation of a heat pump installed on the surface foundation in 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.
Keywords: conversion factor, heat pump, surface foundation, permafrost soils.
