[Abstract]:At present, the situation of air pollution in our country is very serious, which leads to the worrying situation of indoor air pollution in most buildings. In addition, a large number of polluting gases are produced by various decoration materials, household equipment and personnel activities. And now the residential building design is very closed, resulting in a serious deterioration of indoor air quality. With the improvement of people's living standards, people pay more and more attention to the indoor air environment of daily life and work. Based on the study of hydrodynamics, combined with sensor detection technology, signal acquisition technology, liquid crystal display technology and motor fuzzy control technology, this paper combines the national conditions of serious indoor pollution in our country, referring to the relevant control system, and combining with sensor detection technology, signal acquisition technology, liquid crystal display technology and motor fuzzy control technology. A new intelligent fan control system is proposed. In this paper, the research background of ventilation system is introduced, and the development of ventilation system at home and abroad is described. The basic knowledge of mechanical ventilation is introduced in detail, including the calculation of ventilation volume and the basis of turbulence simulation. Then the diffusion of pollutants under different conditions is simulated by Fluent software, which provides support for the design of ventilation system in the future. Next, the hardware design and software design of the control system of fresh air system are introduced, including the design of various sensor acquisition module, human-computer interaction module, driving module, and the design of motor fuzzy control algorithm. Finally, the energy saving effect of the controller is verified by experiments. The intelligent new fan controller studied in this paper can improve the indoor air quality by means of ventilation, in which the integration of air parameter acquisition module of various sensors and the combination of motor control algorithm. The controller has the ability of automatically collecting air quality and automatically adjusting the working mode, and realizes the intelligence of the new fan controller. The main work of this paper provides a reference for the design of indoor air quality controller in the future.
