Abstract

The paper attempted to show the possibilities of improving the energy efficiency and reliability of heat supply services, as well as the quality of heating and hot water supply, by proposing the transition of heat supply systems to closed consumer connection schemes. The authors analyzed the results of experimental studies of elevator inputs that are not able to provide the required parameters in the heating system in time and schemes for connecting hot water to heating networks that have serious drawbacks, on the “Sergeli” and “Yunus-Obod” districts in Tashkent. As the analysis showed, the elevator connection of heating systems and the classical scheme for connecting open hot water supply systems do not provide stable heating modes and guaranteed water supply to places of water parsing with a temperature in the range of 60-70 °C. It is clear that it is necessary to reconsider decisions on connecting subscribers to the heat networks, to choose the best options that will normalize the supply of heating to consumers. In this regard, in the republic, it is proposed to use closed systems: heating the coolant through the heat exchange device of the house`s heating point from the boiler room.
