PURPOSE:To improve heat exchanging efficiency by a method wherein heat accumulating material or paraffin is absorbed into particle type solid particles among high-class oil resin of self-swelling type while said particles are filled into a heat accumulating tank. CONSTITUTION:High-temperature hot-water is supplied from an inlet pipe 3 into a heat accumulating tank 1 in a temperature range, in which paraffin P, absorbed into the solid particles 2 of high-oil absorbing resin filled into the heat accumulating tank 1, shows a solid phase. Then, said paraffin P is changed into liquid phase and the temperature of the same is increased whereby heat is accumulated by absorbing the amount of heat corresponding to a melting heat. When low-temperature cold water is supplied through the inlet pipe 3 under this condition, the temperature of the cold water is increased by heat radiated from said paraffin P and becomes hot-water which flows out of an outlet pipe 4. In this case, the paraffin P is changed into small-diametral solid particles and the surface areas of them are increased remarkably whereby heat exchange is effected very efficiently. |
