Application Analysis of the Wall Insulation Construction Technology in Energy-saving of Building

Wall insulation material can save a lot of wall materials, improve the performance of the wall insulation, save resources, and reduce environmental pollution, which is a new material for interior and exterior wall insulation. In order to study the insulation performance of insulation material, according to the construction process of insulation material, we design the multi-layer insulation wall structure. In order to verify the insulation effect of energy saving, we use the FLUENT software to do numerical simulation on the wall insulation effect, and establish the heat transfer equation of the radiation and solid. We use the CAD software to design large building model, and use GAMBIT to carry on the grid division, finally get the 2D and 3D temperature distribution by means of numerical calculation. Through the finding of thermal efficiency and energy-saving efficiency, insulation wall can significantly improve the energy performance of buildings, which provides technical support to study the energy saving and environmental protection of building.
