DISPERSION FOR THERMAL STRATIFICATION TYPE HEAT STORAGE TANK

摘要

PROBLEM TO BE SOLVED: To obtain a heat storage material to be packed to a thermal stratification type heat storage tank enabling a large difference in density between inflow and outflow water even if a large difference in temperature is not made hardly causing a disorder of thermal stratification even in occurrence of difference in flow velocity between feeding water and discharging water or in addition of vibration. SOLUTION: The heat storage technology is attained by packing a dispersion of a heat storage material of latent heat to the thermal stratification type heat storage tank, especially by packing a dispersion of fine particles of a heat storage material having 5-500 mPa.s viscosity at 25 deg.C. Preferably the fine particles of the heat storage material are microcapsules containing the heat storage material, the dispersion has pH 4-11 and the heat storage material is an aliphatic hydrocarbon compound.
