Modelling of processes of regulation in heating systems

Automatic regulators of coolant temperature have found broad application in modern heat supply systems. These systems implement the oscillatory processes of regulation. Changes of the parameters of regulators in accordance with the instructions don’t practically change anything and the instructions don’t include the procedures of manual identification of buildings as the objects of regulation. Attempts of substantial (tenfold) changes in the controller parameters are very dangerous in real thermal systems. In order to obtain a qualitative picture of the influence of the selected parameters on the processes in control systems, it is advisable to use a mathematical model of the thermal system that is adequate to the real thermal system. The article presents a model of the heating system with reference to commercially available controllers flow temperature for heating and hot water developed by the authors. It is shown the adequacy of the model to the real heating system.
