Investigation of Vacuum Insulation Panel and its Effective Application to Contribute Retrofitting Insulation for Existing Buildings Part 2 Reduction effect of thermal bridge for multiple layers VIP and its application

摘要

Evacuated insulating is become to apply to architectures which can be a single panel with slim and light to easier to construction with higher insulation performance so called vacuum insulation panels (VIPs). Few high efficiency techniques were installed in existing buildings, hence, apply the slim and multiple layers' VIPs to retrofit the insulation performance is a good way. Thermal bridge as a big negative effect for architectural performance once called cold bridge. In this study, calculation model is made for analyzing the insulation performance of full scale VIPs which solved by computational fluid dynamics (CFD). Finally, the insulation performance of VIPs can be validated by the calculation results.
