Abstract

This paper describes a study of the feasibility about the thermal insulation efficiency of porous material on the proposed system. First, the window frame was designed using a porous material such as the packed bed. Then, to verify its thermal insulation efficiency, the temperature contribution of the window frame was evaluated using CFD simulation with different coupled conditions. In addition, to verify the condensation effect, the relative humidity was also calculated. The results show the thermal load was inversely proportional to the indoor/outdoor pressure differences. The condensation in the insulation depends on the outdoor temperature, humidity ratio, and porosity.
