The purpose of this study is to develop the latent heat storage system using erythritol as a latent heat storage material. In this study, the direct contact melting and solidification behaviors of erythritol were visualized in order to investigate the characteristics of direct contact heat storage and release between oil and erythritol. In this direct contact method, if the packed height of erythritol increases, erythritol may be flowed out from a vessel with oil. So to control the packed erythritol height, the effect of a perforated aluminum lattice in the vessel was investigated. The experimental results show that the increase of erythritol bubbles was inhibited by the perforated aluminum lattice. And it is found that the amount of heat release is influenced by the form of perforated aluminum lattices.
