Numerical Analysis and Optimization Methods of the Thermal Bridge Effects on Vacuum Insulation Panels

摘要：

　　The big difference between thermal conductivity of gas barriers and that of core materials makes the thermal bridge effect on vacuum insulation panels inevitable The thermal bridge dramatically deteriorates the overall thermal insulation performance of the vacuum insulation panels.Linear thermal transmittance was introduced to numerically model the thermal bridge Combined with the actual installation situation,the main factors that influence the thermal bridge effect on vacuum insulation panels are thickness and thermal conductivity of the core material,thickness and thermal conductivity of the gas barrier envelopes,the size of vacuum insulation panels and the size of the gap between the panels,etc..The corresponding optimization methods and precautions to reduce the thermal bridge effect on VIP were put forward in this paper to improve the technology of manufacturing and develop the thermal system with vacuum insulation panels involved.
