With the deeping of economic development and sustainable development strategic thinking, Natural vent has become more and more widely used in the construction of industrial plants. Natural ventilator plays an important role in improving indoor air quality and improving employee work efficiency, and its technology research and development has also been valued.

China's climatic conditions are complicated.

The current situation of our country's climatic conditions and smoke vent skylights technology is:

1. The research on the influence of meteorological conditions on natural ventilator is insufficient.

2. The effective use of natural ventilation lacks a complete theoretical analysis of the building structure. Many studies are based on scattered experiments and lack practical guidance. In addition, there are few demonstration buildings that make full use of natural ventilation in architectural design. Many new technologies, such as natural cooling at night and sun shading during the day, also have some difficulties in realizing.

3. The control of the air flow inlet is not mature in research and application.

4. The depth and breadth of theoretical analysis and simulation research on natural ventilation are not enough. From the literature in recent years, it can be seen that only the air distribution and energy consumption of some natural ventilation methods have been simulated, but there is a lack of theoretical research and simulation on various natural ventilation methods and their integrated applications.

5. Most of the research results of natural ventilation are empirical, mostly qualitative or semi-quantitative. At present, systematic and quantitative theoretical and applied research results have not yet been formed.
