Розрахунок теплового пункту з підмішувальними помпами формалізованими методами

Abstract

Traditionally, the heat points are calculated from pressure at the input without influence of neighboring consumers. This cause errors in the analysis of modes of consumers and does not instrument for improvement modes of heating system as a whole. To eliminate these defects can use formalized methods for the analysis of the theory of hydraulic circuits. The object of research was the development of mathematical model of heating points with mixing pumps and methods of setting up by formalized methods. In these heat points also install the heat flow regulator for automatic control mode. This regulator is an active element. Its hydraulic resistance varies depending on the heat take-off from the network. Calculation of flux-distribution for these heating points must perform two nested iterative procedure. In the inner loop calculate flux-distribution with fixed hydraulic resistance brunches. External process for the algorithm given in this paper corrects resistance regulators to minimize the difference between the current and desired heat-carrying agent. Developed a mathematical model and algorithm are instruments for identifying and providing energy saving modes of heat points and heat supply system as whole.
