DISTRICT HEATING SUPPLY SYSTEM USING HEAT PUMPS
The paper presents a technical solution aimed at improving the efficiency of the district heating system of remote heat consumers through the introduction of heat pump systems. The indexes of thermal efficiency that allow to compare various schemes of application of heat pumps in heating systems(the use of heat pumps as peak sources, the use of heat pumps with the reverse network water as a low-grade heat source, the use of heat pumps for reducing the temperature chart of district heating) are performed.
