<P>PROBLEM TO BE SOLVED: To provide a heat exchanging system and a heat exchanging method using a heat storage material, capable of being stably used at all times by efficiently accumulating and recovering the ordinary temperature exhaust heat dispersively generated for a long period in a compact space of a heat storage tank, and stably utilizing the stored heat as a heat source in a time zone variable from day units to year units. <P>SOLUTION: This heat exchanging system comprises the heat storage tank provided with a heating medium flow channel and retaining the heat storage material molten/solidified by exchanging the heat with a first heating medium circulated and supplied from a high heat source, a heat exchanger mounted in the heating medium flow channel, heating a second heating medium supplied from a low heat source by the first heating medium, and discharging or circulating the same to the low heat source through a heat transfer face, a heating medium supplying means for supplying the first heating medium to the heating medium flow channel and/or a stirring means mounted on the heating medium flow channel and stirring the first heating medium, and a control part for controlling thicknesses of a suspension layer and an emulation layer formed around the heat transfer face, and a concentration of the heat storage material by using the heating medium supplying means and/or the stirring means. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
