THE HEAT BALANCE MODEL OF RESIDENTIAL HOUSE

Abstract

This paper deals with the heat balance model of residential house. It is very important to maintain desired comfort in building and reduce heating costs. Heating costs depend on building heat loss factor, air infiltration rate and heat loss in the heat supply system. Values of these parameters may be reduced by improving construction of the building and developing optimal control of heating system. The heat balance model was used for development of a control system, which enables to regulate the heating installation of a building with continuous occupation. The system consists of autonomous water flow controllers in radiators and water temperature controller in boiler. It uses simple control algorithm. The system was developed and tested by simulation. The results obtained showed that the system allows providing high-energy conservation and reliable comfort.
