VACUUM HEAT INSULATION STRUCTURE FOR BUILDING

摘要

PROBLEM TO BE SOLVED: To provide a vacuum heat insulation structure for a building economically and finely applicable also to a general housing capable of increasing vacuum by using usual tap water without being required for specially operating a vacuum pump. SOLUTION: The vacuum heat insulation structure for the building is equipped with a vacuum heat insulating panel 21 providing a vacuum space 22 inside thereof and a vacuum suction device 41 connected to the vacuum space 22 of the vacuum heat insulating panel 21 to suck air in the vacuum space, and the vacuum suction device 41 uses an aspirator operated by the tap water. A check valve 45 for preventing the inflow of air into the vacuum space from the vacuum suction device 41 side is provided between the vacuum suction device 41 and the vacuum space . The vacuum space 22 is filled with a permeable reinforcing material 25. COPYRIGHT: (C)2005,JPO&NCIPI
