<P>PROBLEM TO BE SOLVED: To provide a heat storage sheet capable of keeping a comfortable room temperature for a long time even if a large change is caused in outside air temperature by arranging the heat storage sheet on the inside face of a wall, a ceiling, a floor or the like of a house by sticking the sheet to gradually release the heat previously stored by an air conditioner or a natural energy. <P>SOLUTION: The heat storage sheet is obtained by applying coating of microcapsules encapsulating a heat storage material having 0-40°C melting point on one surface of a sheet-shaped supporter having 0.01-0.1 kcal/m/hr/deg heat conductivity. The amount of the heat of fusion per m<SP>2</SP>heat storage sheet is preferably within the range of 10-600 kJ/m<SP>2</SP>, and hollow particles are preferably coated on the other side of the microcapsule-coated face. The density of the sheet-shaped supporter is preferably 0.01-0.25 g/cm<SP>3</SP>, and a nonflammable sheet, especially a metal sheet is preferably stuck on the microcapsule-coated face. The heat storage sheet is utilized by directing the microcapsule-coated face to the interior side as a wallpaper for interior decoration of a building. <P>COPYRIGHT: (C)2004,JPO |
