On the relationship between thermal conductivity and vacuum of vacuum insulation panels

HU Yong-nian

Abstract

The relationship between thermal conductivity and vacuum of vacuum insulation panels with two kinds of core materials was investigated by comparing experimental datas with theoretical calculation results.The gas pressure in the vacuum insulation panels was tested by reverse vacuum method.The fabrication technology and the method to maintain vacuum degree as well as the way to prolong service life were discussed.
