This study aims to design the PCM radiant floor heating system and to calculate optimal temperature of the PCM. The results of this study is as following. A existing radiant floor heating system have some problems to use a lot of hot water and energy owing to low heat storage performance of autoclaved lightweight concrete and mortar. for this problem, this study suggested the design of PCM radiant floor heating system applied to PCM, which is a heat storage material. The PCM radiant floor system consists of 210 mm concrete slab, 20 mm cushioning material, 15 mm mortar, 10 mm PCM aluminum case, 55 mm mortar, and a finishing material. It was analyzed that the PCM temperature (Melting point) scope for the PCM radiant floor heating system is 32-39 ℃ through the heat transfer model if a finishing material of 5 mm thickness is used. |
