Description
  • The final idea of the room model development is to simulate thermal response of the building construction into changing boundary conditions. To simplify this very complex task the room model was created and subsequently the thermal analysis was calculated in COMSOL Multiphysics environment. The main idea of this article is to study radiation influence to overall room temperature. Heat transfer by radiation can cause two problems during simulation. Firstly, this phenomenon is strongly non-linear and secondly, precise emissivity value is uncertain. There is discussed an error due to neglecting heat transfer by radiation for internal building conditions and also the possibility to model radiation by means of raising the value of heat transfer coefficient by convection. Temperature course of the simplified model is analysed and compared to the original model output.
