Аннотация

The effective use of heat power in heat supply systems requires the development of new methods for central and local regulation of heat supply systems, the use of heat supply schemes with associated heat supply. The development of such technologies requires modeling and systematic calculations of variable modes of joint operation of local heat-consuming systems. Currently used methods for calculating such operating modes of heat exchangers usually use constant parameters of heat exchangers. Such methods are not applicable in cases for large changes in temperatures and flow rates. Therefore, the calculation of variable modes of tied heat exchangers is usually performed by the method of successive approximations and is very time-consuming, which complicates the construction of a control system. In the present work, a fairly simple engineering technique is proposed for calculating the operating modes of heating stations of heat supply systems with associated heat supply. The basis of this technique is the use of previously derived analytical formulas that describe the change in the parameters of heat exchangers for various schemes of heating stations and temperature graphs of central regulation. The developed method allows the calculation of variable operating modes of the heat supply system without resorting to the method of successive approximations. The efficiency of the proposed methodology was tested on the operational data of the central heating station in the Kalinin district of Novosibirsk.
