PURPOSE:To make it possible to accumulate and radiate heat in an efficient manner by a method wherein a heat accumulating agent consisting of a substance capable of receiving and radiating heat according to its phase change from liquid to solid is sealed into a number of micro-capsules which are floated or mixed in a liquid phase medium. CONSTITUTION:The substance capable of receiving and radiating heat according to its phase change from liquid to solid, for example, normal hexadecan, N- tetradecan or the like is sealed into a number of micro-capsules made of aluminum or polyethylene and the capsules containing the substance therein are floated or mixed n the liquid phase medium to thereby provide the heat accumulating agent 1. Then the heat accumulating agent 1 is filled into an adiabatic tank 2 having an outlet provided with a filter 6 adopted to prevent the flowing of the capsules outside the tank 2 so that the capsuled substance reacts against the liquid phase medium. In this case, if water is used as the liquid phase medium, it is possible to circulate the water directly as a heat medium and by so doing, it is possible to accumulate and radiate heat efficiently to a degree about two times the efficiency of the heat accumulation tank utilizing the specific heat of water. |
