【 摘 要 】

The subject of research is an efficiency assessment of low-potential ground source heat in heat pump systems under climatic conditions in Russia with regard to energy rates. As a result of the study, zoning of the Russian Federation territory has been presented, with zones classified according to: a) electric and heat energy rates, heat energy rates for domestic hot water supplies, as well as according to electric and heat energy rates ratio; b) ground source heat pump systems efficiency, considering actual climatic conditions of regions and ground temperatures changes over multiannual operation. Furthermore, comprehensive assessment of ground source heat pump systems efficiency has been made, based upon prices of heat energy generated by such systems with account of an actual coefficient of performance, and heat energy from a conventional heat supply source. Corresponding maps have been attached.
