In order to reduce heat energy demand in residential building, thermal insulation and indoor air tightness become more important. However, in a well-insulated environment, internal heat gain caused by solar radiation, metabolism and losses of home electric appliance (i.e. refrigerator, lamp, television, etc.) can be dominant to home global energy management. To quantify and to modelize the heat gain due to home appliances, we begin experimental measurements in a wellinsulated room. The first step in this work is the identification of the room. In this paper we suggest a 1R1C lumped parameter circuit which presents a building thermal model using thermalelectric analogy. Then, we identify the circuit components (the global thermal resistor and the global thermal capacitor) from the heat balance equation and experimental results. Based on the model and the obtained parameters, we simulate the indoor temperature of the model using Matlab/Simulink. To check its accuracy we compare the measured data and simulation results and calculate their error ratio.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
