ENERGY EFFICIENT SYSTEM OF URBAN AUTONOMOUS HEAT SUPPLY BASED ON HEAT PUMP TECHNOLOGY

Abstract

In this article, the essence of the proposals is the introduction on a mass scale of small reversible heat pumps (HP), which are installed in each apartment. At the same time, the connection of the house to the centralized city heating system is carried out not to the "direct" pipe, but to the "reverse" one, in which the water temperature is 40 - 50°C. Heat pumps, cooling this water, pump heat to the room air, the temperature of which is ≈20°C. In this temperature range, the thermal efficiency of HP will have a value of 5-6. The consumption of heat from “return” water makes it possible to connect new heat consumers to overloaded heating mains .
