Analysis and modelling of influence non-stationary exterior temperature in interior temperature and thermal heater capacity

Task of this paper is to be analyzed and modeled the dynamics of thermal power by the heater located inside a closed environment, and the interior temperature in conditions when the heat exchange through walls is stationary and the exterior ambient temperature varies periodically. Modeling of interior temperature is based in thermal balance between thermal capacity of the heater, air heat accumulation and the heat losses through walls. So, in analytical and graphical way are presented the changes for interior temperature, accumulation heat and transmission heat. By means of corresponding diagrams there are presented the important results which show the practical side and possibilities to optimize the heater thermal capacity respectively the optimal time manipulation with the heater.
