The present study is investigated the direct contact solidification behavior between latent heat storage material and heat transfer oil. Purpose of this study is development of a latent heat storage system which is suggested using waste heat of temperature region (100〜200℃) as heat source from factories. Mixture of mannitol and erythritol was adopted as phase change material (PCM). To examine detailed heat exchange behavior, test section was constituted glass tube and the number of nozzle hole for injecting heat transfer oil is one. By this study, the following matters became clear. Size of injected oil droplets rise with the increasing flow of oil. Flow path is different depending on the height direction.
