[0002] Doors are the entrances and exits of buildings, and windows are the main openings for indoor lighting and ventilation. Therefore, doors and windows are an important part of construction projects. The air tightness of doors and windows refers to the ability to block air infiltration when the doors and windows are closed. It is one of the most important properties of doors and windows. For example, the air tightness of doors and windows can affect the thermal insulation, sound insulation, and windproof properties of the building, and then affect the quality of the construction project. Therefore, the air tightness test of doors and windows aims to ensure that the doors and windows have good sealing performance to prevent air infiltration, thereby improving the energy efficiency of the building and enhancing the living comfort.
[0003] In the existing process of air tightness testing of doors and windows, one part is to use wind force to blow directly in a non-enclosed manner, and then use a wind speed sensor to detect the circulating wind force. However, this detection method is easily affected by the natural wind blowing from the outside and the detection result is affected. Another detection method is to seal the doors and windows and then detect the pressure change through a pressure sensor. If gas leakage occurs in this detection method, it will affect the result of the air tightness test. For this reason, we propose a device for testing the air tightness of steel doors and windows.
