The present paper is suggested to reuse waste heat in middle temperature region (100℃〜250℃) from factories. The purpose of this paper is comparing the melting and solidification characteristics of the mixture of mannitol and erythritol (C_M=70mass%, mannitol[70mass%]: erythritol[30mass%]) and mannitol as a PCM in a vessel with pipe heat exchanger. The experimental result was confirmed that the heat storage speed of the C_M=70mass% mixture is faster than that of the mannitol with an average 1.5 times in each flow rate of oil.
