About Features of Derivation of the Regulation Equations for District Heating Systems

Abstract

A detailed "transcript" entry procedures and validation of algorithms proposed by E.Y Sokolov to regulate district heating both the heating load (weather control) and on the combined load of heating and hot water is given. The features of this approach to the problem of regulation, its advantages and disadvantages are analysed. It is shown that the algorithms are more common than ones of the E.Y. Sokolov, as they allow to calculate the required value of the coolant temperature at any value index heaters installed in the building. It is noted that centralized regulation is quite rude, not taking into account the specific thermal insulation properties of the building and its thermal performance of the heating system. In this regard individual weather regulation for each building is more preferable, it is realized or at the independent scheme of connection of its system of heating to thermal networks, or in the presence on input of adjustable knot of mixture. The algorithm of the individual weather control and a block diagram of the developed adaptive thermal management system of the building, realizing a combined management principle to the setting of the weather compensator for operational data are given. It is noted that the implementation of a nominal weather graphics for buildings with elevator heating system is also available, but only for that you need to apply a method of controlling a pulse.
