THE METHOD OF OPTIMIZING THE OPERATING COSTS OF THE HEATING SYSTEM OF AUTONOMOUS BUILDINGS
This paper proposes a method of optimizing operating costs during the operation of the heating system of autonomous Earth sensing centers, command posts and other institutions that ensure the functioning of the rocket and space complex of Ukraine due to the optimization of mass consumption of coolant and solid fuel in the presented autonomous structure with a total area of 25 m2. Biofuel in the form of pellets is used as fuel. A heating system was designed for the selected building, for which a target function was defined to minimize operating costs. Expressions for thermal and hydraulic losses during the operation of the heating system were obtained. Heat losses of the building through the walls and ceiling are determined. Calculations of hydraulic losses of the heating system were also carried out. Mathematical models of elements of the heating system (solid fuel boiler and heating battery) were obtained. A mathematical model was built for finding patterns of changes in thermophysical parameters in the elements of our system. Models of radiators, solid fuel boilers and heat losses due to building enclosures are considered. The task of optimizing operating costs during the operation of the heating system was set and solved. The results indicate the possibility of significantly reducing heating costs due to the selection of the optimal mode of operation of the heating system. The obtained results can be used in the optimization of operating costs during the operation of the heating system not only when using biofuel as an energy source in the form of pellets, but also when using traditional types of fuel, such as natural gas and coal.
