LATENT HEAT STORAGE BODY AND LATENT HEAT STORAGE UNIT, AND FIRST TIME MELTING METHOD OF LATENT HEAT STORAGE BODY

摘要

PROBLEM TO BE SOLVED: To provide a latent heat storage body and a latent heat storage unit in which an expensive heater or the like is not needed, the outflow of the latent heat storage body is not caused, and that enable the shortening of the required time of the first melting of the latent heat storage body, and to provide a first time melting method of the latent heat storage body.SOLUTION: The latent heat storage body 2 is composed of a fibrous material, is characterized in that the density after melting is larger than that of a heating medium 3, and by not being dissolved in the heating medium 3, and directly contacts with the heating medium 3 and exchanges heat. It is desirable that the bulk density/true density of the fibrous material is at least 0.001 and at most 0.7, and the fibrous material is a sugar alcohol. The first time melting method of the latent heat storage body 2 is characterized in that the latent heat storage body 2 is charged in a container 4 from an opening 7, then the heating medium 3 in which the temperature is made higher than the melting point of the latent heat storage body 2 is supplied into the container 4 from a heating medium inlet 5.
