Effect Of Aging On Service Life Of Vacuum Insulation Panels

Vacuum insulation panels (VIPs) represent in their pristine condition a high-tech state-of-the-art thermal insulation solution with thermal conductivities 5 to 10 times lower than traditional thermal insulation. VIPs consist of a solid porous core sealed with an airtight and watertight foil maintaining vacuum in the core.

This work presents an overview of the graphical plots relevant for predicting service life of VIPs with respect to increase in thermal conductivity. The governing equations are given in the full version of the article. Furthermore, the background for and how accelerated ageing of VIPs may be carried out is discussed. Finally, some preliminary accelerated aging experiments are presented.
