    Abstract: 熱能之存儲對於太陽能應用及隔絕而言,具有舉足輕重的地位。在各種儲能之技術中,潛熱式儲能技術由於具有提供高能量密度及在相變化材料(PCM)之相轉換的固定溫度點工作之能力,而被公認為最有發展潛力。相變化材料在吸收熱能或釋放熱能的時候,本身處於幾近恆溫的狀態,不會有局部溫度驟升或劇降的情況產生。大多數的低成本儲能材料的熔點有其一定範圍。然而,作為潛熱儲熱材料須具備某些條件才能被工業界所使用,亦即必須要能在能源供給和需求之間取得平衡的能力,因此必須探討在溫度變化過程中其熱傳導、熱對流之特性及可能發生的體積變化對於材料熱阻所造成的交互影響。
    所以,本研究擬探討添加陶瓷微粒之相變化材料接觸界面間微熱傳的特性,以提供PCM應用於綠建材等環保領域設計及研發的參考依據。
    Thermal energy storage is very important for solar energy applications where solar radiation (variable nature) is the energy input. Amongst various thermal energy storage techniques, latent heat storage is considered to be most promising due to its ability to provide the high energy density and to store the heat at a constant temperature corresponding to the phase transition temperature of the phase change material (PCMs). PCMs are latent heat storage materials. A large number of PCMs are known to melt with a heat of fusion in any required range. However, for their employment as latent heat storage materials these materials must exhibit certain desirable conditions. Such as heat conduction, heat convection, the variations of volume. Moreover, the PCM to be used in the design of thermal storage systems should pass the above conditions in advance.
    Therefore, this study was to investigate the effect of micro ceramic particle on the micro heat conduction between the contact interfaces for phase change materials.
    The study will be very helpful for the design and development of green building materials in the future.
