Thermal network of coupled building and electrical appliances

As power density of electrical appliances in a building sector grows up, its thermal effect also increases especially within a well-insulated building. In order to investigate the heat gain of these appliances, this paper proposes a dynamic thermal model of electrical appliances which is embedded in a building thermal analysis by using thermal network method. For this, thermal-electrical analogy and a static model and a dynamic model of electrical appliance coupled to a thermal network of a building are presented. As applications, a monitor and a computer are selected and their thermal models are adapted to a building model. Finally, their thermal influence is observed by experimental results and simulation one.
