PURPOSE:To obtain a heat accumulating device capable of generating heat surely when the heat is to be generated by a method wherein a path opening and closing means, communicating the inside of a crystal holding chamber with the inside of a heat accumulating vessel or separating them switchably, is provided in the titled device. CONSTITUTION:The heat of a heater 5 is generated before using a pocket heater to heat accumulating medium 3 or hydrogenated sodium acetate of crystalline phase in heat accumulating vessels 4a, 4b to the melting point (58 deg.C) thereof or higher. The hydrogenated sodium acetate of crystalline phase is gelled gradually and then is gelled perfectly. After the heat accumulating medium in the heat accumulating vessels 4a, 4b is dissolved perfectly, a plug 5b is pulled out of a socket and the heating is stopped. The temperature of the heat accumulating medium 3 in the heat accumulating vessels 4a, 4b is reduced under heat accumulating process, however, super-cooled condition is maintained and heat accumulation is effected under gelled condition. Under heating process, necessitating room heating, the bottom 66b of the spool 66 of a valve 6 is pushed, then, a valve body 63 is pushed up and a space A is communicated with the space B, therefore, the heat accumulating medium under the condition of over-cooled gel in the space A is contacted with the crystal species in the space B whereby latent heat, the heat medium, is crystallized at a stroke and latent heat accompanied by the transition of phase is discharged to effect room heating. |
