Background technique

Housing is the place where people live and live every day, and fresh and clean air is the basis for people's health and quality of life. At present, the ventilation method used in residential buildings is mainly natural ventilation. As the airtightness of building exterior windows continues to improve, natural infiltration ventilation can no longer meet the requirements of indoor air quality; if windows are used for ventilation, not only the ventilation volume and airflow organization are difficult to control, but also noise pollution will be caused. Therefore, mechanical ventilation, or a combination of natural and mechanical ventilation, has become the main means of solving residential indoor air quality.

While improving the indoor air quality, mechanical ventilation also directly and instantaneously affects the indoor thermal and humid environment. The amount of ventilation and the ventilation mode are related to whether the building is energy-efficient. For buildings with better insulation performance of the envelope structure, the loss of heat or cooling due to indoor and outdoor ventilation becomes the main part of the energy consumption of building heating and air conditioning. Therefore, how to ensure good indoor air quality and keep ventilation energy consumption at a low level has become a relatively prominent and urgent problem to be solved at present.
