Accelerated Aging Test of Vacuum Insulation Panels with Different Barrier Films

摘要：

　　Investigation of the permeation of oxygen and water vapor through barrier films of VIPs is crucial for determining the long-term performance of VIPs.In this work,we investigated and simulated the permeation mechanism of oxygen and water vapor through barrier films.Permeation equations for polymer film with single defective layer and polymer film with double defective layers are obtained by numerical simulation and curve fitting.Both equations take into account the characters of the aluminum layers as well as polymers adjacent.With the equation derived,the acceleration ratios of common acceleration strategy with elevated temperature and pressure difference are calculated.Acceleration strategy with volume reduction is introduced and implemented to provide higher acceleration ratios and avoid unequal acceleration for different permeants due to elevated temperature and pressure difference.
