Research on Air Purification Wall Based on Heat Exchange Principle

With the acceleration of urban modernization, the use of prefabricated buildings on construction sites is increasing year by year. However, the following problems arise: the environmental quality of construction sites in our country is poor, the living comfort of prefabricated buildings is low, the recycling rate is low, and the indoor air is dirty, affecting the health and comfort of indoor personnel. Therefore, it is of great significance to complete the new wall for indoor air purification. Through the design of the three-layer interlayer, the heat exchange between the inside and outside air and the purification of the indoor air are realized, and a new type of movable plank house wall with low price and simple and ingenious structure is designed, which not only can improve the living comfort inside the plank house, but also can ensure the maximum embodiment of the energy-saving benefits of materials. The experimental results show that the indoor air quality of the air purification wall based on the heat exchange principle is improved by 21.6%, and the indoor temperature change in the air purification process can be effectively avoided.
