PROBLEM TO BE SOLVED: To prevent phase separation due to a density difference between solid and liquid phases in a heat storage system which dispenses with a heat storage tank as a receiver of a liquid heat storage material, enables effective use of a space and arbitrary design of a shape without being restricted by a form, a place, etc., and also utilizes a phase change between the two phases. SOLUTION: A heat storage device is composed of a piping 4 for heat exchange and a heat storage body 1 provided around the piping, and this heat storage body 1 is constituted of a liquid absorbing material 3 containing a heat storage material 2 of a liquid functioning as a sensible or latent heat storage material. The liquid absorbing material 3 is constituted of a substance having a function of absorbing and holding a liquid and it is formed to be tubular, for instance, and fitted around the piping 4. The heat storage material 2 held in the liquid absorbing material exchanges heat with a medium 5 passing through the piping 4 for heat exchange and stores the heat as a sensible heat or as a latent heat accompanied by a phase change. |
