Experimental research on thermal performance of shape-stabilized phase change material floor
Experimental study was conducted on the thermal performance and energy saving effect of a room with shape-stabilized phase change material (PCM). The results showed that the mean indoor temperature of the room with PCM floor was about 2 deg C higher than that of the room with normal floor and the indoor temperature swing range narrowed greatly. The results also manifested that by applying shape-stabilized PCM in room suitably, the thermal comfort level could be raised and space heating energy in winter could be saved. Finally, the experimental results enriched the database for the further modeling and simulation research. As the conclusion, from the experiments there were found very attractive characteristics of this novel shape-stabilized PCM which can be great contribution to optimize the indoor climate. Using 70 wt% paraffin as the dispersed PCM, and 15 wt% polyethylene and 15 wt% SBS as the supporting material will form a kind of total new low price and high thermal performing PCM. The swing range of temperature on the floor surface was markedly changed, which was narrowed from around 51 deg C under condition without PCM plates down to less than 35 deg C under condition with shape-stabilized PCM plates, and the temperature distribution on the floor surface is very even everywhere. Congruously, the fluctuation of the indoor air temperature was narrowed from 39 deg C to 31 deg C . All of these directly lifted up the living satisfaction level.
