<P>PROBLEM TO BE SOLVED: To efficiently accumulate heat and to realize space saving of a device. <P>SOLUTION: This heat storage type heat supply device comprises a heat storage tank 2 storing, in its internal space, erythritol 22 for accumulating heat, and oil 21 exchanging heat by contacting the erythritol 22 and lower in specific gravity than the erythritol 22; a heater 3 provided integrally with the heat storage tank 2 and capable of supplying heat to the taken-in oil 21 and discharging the oil 21 to the lower part of the internal space of the heat storage tank 2; and a heat exchanger 4 provided outside the heat storage tank 2 to take out heat of the taken-in oil 21. The heat storage type heat supply device further comprises a first passage tube forming a first passage for directly supplying the oil 21 in the heat storage tank 2 to the heater 3, a second passage tube forming a second passage for supplying the oil 21 in the heat storage tank 2 to the heater 3 through the heat exchanger 4, and three-way valves 5a, 5b switching the passage of the oil 21 to lead the oil 21 stored in the heat storage tank 2, to the first passage tube or second passage tube. <P>COPYRIGHT: (C)2007,JPO&INPIT |
