Building thermal mode control with combinied heating system

Abstract

The way of heating control with air and radiator sources in the heating system of the building is considered in the article. Model predictive control algorithm for optimal thermal control in the building is presented. The algorithm implements thermal control over receding horizon with set temperature diagram. Computing of thermal environment prediction is based on the thermal model of the building. The energy cost function under certain boundaries is used to estimate optimal control strategy over receding horizon. The summarized cost for electrical and thermal energy under set tariffs are taken into account in the cost function over receding horizon. The mathematical thermal model of the building and cost function were defined for air heating system with progressive and relay control scheme of the fan.

Modeling results of predictive control algorithm for thermal control in the building with set temperature diagram and set tariffs for electrical and thermal energy were shown and analyzed.
