Residential heating system in multi-physical domains

Modelling and simulation are important tools that have novel applications in all engineering disciplines because they combine engineering and technology. Large systems that involve different domains can be modelled and integrated. This approach facilitates modelling and simulation of complex real-world systems. As residential heating systems become electrified, their contribution to the residential load becomes significant. In this paper we investigate multi-physical domain simulation model for residential space heating. An electric heat pump heating system for a detached house is simulated and analysed with thermal and electric domain models. Analyses are performed on the operational cycles of the heat pump based on occupants´ thermal comfort preferences. The potential effects of aggregated number of residential heat pumps on the electricity network are briefly studied.
