- Abstract
- The purpose of this study is to suggest the building wall with the PCM which uses high and low emissivity film forimproving the thermal insulation performance during the summer. Each film rotates around the PCM and it used according toits purpose. The low emissivity film reduces the radiant heat from the outer wall to the PCM during the daytime and the highemissivity film helps to discharge the radiant heat from the PCM to the outer wall during the night time. The insulationperformance was estimated by a numerical simulation. The results indicated that the proposed system reduced 62.5% and 44.6%of total heat transfer to indoor from outdoor compared with conventional PCM wall and thermal insulation
