[Abstract]:In order to study the effect of membrane permeability on the thermal performance of vacuum insulation plate, the permeability principle and the factors affecting permeability of the membrane were analyzed numerically. The temperature, humidity, dissolution coefficient and diffusion coefficient were analyzed respectively. The relationship between permeability, temperature and relative humidity have great influence on membrane permeability, while relative humidity has little effect on membrane permeability. The water vapor permeability of three kinds of membranes was studied at different temperatures. The results show that the type and temperature of membranes have a great influence on the permeability of membranes, and the permeability of membranes will increase with the increase of temperature. The results are of great significance to the selection of vacuum insulation plate membrane, the optimization of performance and the development of vacuum insulation material.
