Temperature Evolution in Building Wall System with Dynamic Control of Heating Systems

EasyChair Preprint 5892

Abstract

I focus on the dynamic control of heating systems, primarily district heating systems in this study. With the dynamic control of the heating system we can defined the temperature changing in the wall structure. The control of district heating systems is currently static.  We set the primary flow temperature and the circulating hot water volume flow to the heat source with the estimation of the average daily temperature. These values are set empirically. The control of the thermal centre is similarly static. The secondary flow temperature and the circulating secondary hot water volume flow are set according to the estimated heat demand of the building, the control is choked. There is no exact practice currently on how to consider thermal inertia of boundary walls, the amount of heat stored in the walls and the damping effect. In our study, we present models in which we consider the damping and delaying effect of the walls and the heat storage in the walls. The model is of concentrated parameter and describes development over time regarding the air temperature of the habitation and the average wall temperature considering the outside temperature.

Keyphrases: Fourier-equitation, district heating system, instationary, predictive control
