MODELLING OF THE DECENTRALIZED SOURCE OF THE HEAT SUPPLY AND CHOICE OF OPTIMUM PARAMETERS OF ITS WORK
Abstract
The analysis of collaboration of a real source of the decentralized heat supply, thermal network and four consumers of thermal energy is carried out. On the basis of Kirkhgof's laws the system of the equations describing mathematical model of a hydraulic chain a source - a thermal network - consumers is made. Criterion function of a factor cost on compensation of thermal losses in a thermal network depending on temperature schedule of the heat-carrier and compensation of expenses for heat-carrier transfer is defined. Natural experiment on the basis of which real factors of hydraulic resistance of each site of a hydraulic chain of model are defined is made. By means of a package of the applied MachCAD programs the optimum method of regulation, the temperature schedule and a relative expense on a source at which criterion function of a factor cost reaches a minimum will be defined by methods of mathematical modeling. The economy from introduction of the offered model of a heat supply is defined. Concrete recommendations about transfer of work of a source on an optimum method of regulation of thermal loading are made.Keywords. Regulation of thermal loading. Temperature schedule. Criterion function. Factor cost.
