<p><P>PROBLEM TO BE SOLVED: To expand an effective temperature range of heat insulation performance of a heat insulation panel using a vacuum heat insulation material as compared with a conventional one. <P>SOLUTION: This application relates to this heat insulation panel 22 using the vacuum heat insulation materials 15A and 15B composed by vacuum-sealing core materials 16A and 16B with an airtight film 17. A plurality of kinds of the vacuum heat insulation materials 15A and 15B having different heat insulation characteristics defined by the core materials 16A and 16B are stacked in the panel thickness direction; the insulation material 15A having the heat insulation characteristic with a relatively high effective temperature range is disposed on the side set at a relatively high temperature in the panel thickness direction; and the insulation material 15B having the heat insulation characteristic with a relatively low effective temperature range is disposed on the side set at a relatively low temperature in the panel thickness direction. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
