Building energy saving is an important theme in the development of construction industry. It has important significance to achieve wall heat insulation. MATLAB software was utilized to model the heat transfer coefficient and obtain the main factors influencing airflow reverse osmosis principle based on the research of airflow reverse osmosis principle. The influence of seepage layer thickness and seepage velocity on thermal performance of airflow reverse seepage principle was determined and the optimal value was obtained through ANSYS simulation. An energy-saving plate was designed to build a removable house, and the heat conduction characteristics of air reverse osmosis principle were verified by experiments. The simulation results showed that heat conduction characteristics of the heat insulation wall based on airflow reverse osmosis principle were optimal when the thickness of the seepage layer is 40mm and the seepage velocity is 0.008m/s. The experimental results showed that the heat-shielding performance of the wall based on the airflow reverse osmosis principle was improved by 18.56%, and the thermal insulation performance was improved by 24.15% compared with that of the ordinary wall, and heat insulation wall based on airflow reverse osmosis principle had excellent heat conduction characteristics.
