ABSTRACT
In this paper, we propose equations that allow us to directly determine the change in the thermal power of heat exchangers depending on the temperature of the outside air and the temperature of the network water returned to the heat network. These equations are obtained on the basis of systematic modeling of variable modes of operation of the heat supply system, by previously developed method of the authors. The operational characteristics of the operation of the heating point are taken into account by the coefficients of the equations for the determination of which the calculation formulas are obtained. The equations used are valid for heating points with a two-stage sequential scheme of hot water heaters in maximum water consumption mode. This approach is tested on operational data for a heating station in Moscow. It is shown that the calculation data for the proposed equations are in good agreement with the results of numerical modeling and with operational data.
