Abstract
This article presents a brief history of the country’s heat supply system development. The types of heat supply systems are considered, their brief characteristics are given. Methods for determining the heat load for household needs (heating and hot water supply) of urban residents are presented. The study of the coolant temperature influence on the air temperature in the room was carried out. The study used an experimental-theoretical research method. As a part of the experimental study, the data of temperature measurements in one of the heating points in Tyumen were requested. Within the framework of a theoretical study, the air temperature in a living room was calculated, depending on the coolant temperature according to the schedule of the CHPP and according to the supply in the supply heat pipe. In carrying out the theoretical study, standard methods were used for carrying out thermal calculations of heat supply systems, statistical research methods, as well as standard computer programs. The need to regulate heat energy is determined and the types of regulation are considered. The analysis of the adopted temperature schedule of the CHPP was carried out and a comparison was made with the calculated temperature schedule. The solution of the equation for determining the air temperature in the room is given. The air temperature in the room depends simultaneously on two factors: the temperature of the heating medium and the temperature of the outside air. As a result of the study, the presence of a discrepancy between the temperatures of the network water supplied to consumers and the created air temperature in residential premises was determined. The intersection point of the calculated temperature schedule and the CHP schedule was determined. The necessity of observing the calculated temperature schedule of the central quality regulation has been substantiated. The necessity of heat supply at a constant flow rate of the heat carrier has also been substantiated.
