Abstract
Abstract The article is devoted to the use of heat pump installations in heat supply systems with TPP. The technique of the primary assessment of the efficiency of heat pumps in district heating systems is considered, on the basis of which it was concluded that it is possible to get the maximum effect from the introduction of a heat pump in the inter-heating period to compensate for the HPU load when using a heat pump at a consumer and transferring the heat and power plant to the condensation mode from the condenser to the heating system. At the same time, for greater effect, the heating system must be cooled below 20 ° C in order to use the low-temperature potential of the heating network. Based on the findings, a comprehensive heat supply system has been developed that includes TPP and HPU installed at the consumer by the universal compensation system of hot water supply load (UCS-HWSL) scheme. Modernization of the basic heat supply system to the UCS-HWSL system with a lowered temperature schedule will allow improving the technical and economic indicators of the Chita TPP-1.
