The Impact of Barrier Laminates on Thermal Property and Service Life of Vacuum Insulation Panels
As a high-performance thermal insulation method for energy conservation purpose,Vacuum insulation panels (VIPs) have been widely applied in various fields.However,the service life,that is,thermal performance versus time,is an interesting focus for researchers,manufacturers and users.Rarefied gas pressure inside the panel represents the vital influence on thermal insulation performance.The barrier laminate is explored to analyze the aging of service life.The primary objective of this work is to theoretically define the service life of VIPs,and the impact factors are respectively analyzed.The effects of gas & moisture permeation through the barrier laminates,on the effective thermal conductivity of VIPs are studied.Three typical barrier laminates,AF,MF1 and MF2 are introduced and the properties parameters are measured.Taking them as the envelopes,the VIPs are analyzed for the tendency of the effective thermal conductivity changes.The service life is numerical analyzed and predicted.Accelerated ageing tests are taken to support theoretical predication model at70℃ & 80%RH or under 800kPa high exterior air pressure.The comparison of simulation work and the accelerated aging experiments show that the VIPs are durable and high quality for energy conservation purpose.And the optimization methods according to authors research are also given to prolong the service life of VIPs.
