Description

In this paper, the authors report on the thermal storage amount of a PCM window shade having different melting points, an examination of its use as an external sun shade. When the window shade filled with gelled PCM was installed in a window, the authors confirmed that the maximum surface temperature of PCM window shade reduced by up to 4-7K. In addition, the solar heat transmission could be reduced by about 12% when the blind was installed. In addition, the effect of PCM window shade could be applied to the granular PCM as new material in order to solve the problem of workability in the same manner. The workability of granular PCM could be easily adjusted with filled mixing even for different melting points. When mixing PCM of different melting points, the thermal storage amount showed the intermediate characteristics of both. The solar transmittance of the window shade was improved to 0.9 by filling with the granular PCM. Finally, the solar radiation shielding performance of the PCM blind filled by mixing granular PCM of 50℃and 32℃ melting point was almost as same as that of the gelled PCM of 25℃.
