Abstract: :With the improvement of people's living standards, the performance of range hoods has gradually improved. The large air volume and large static pressure of the range hood have become the publicity selling points of many manufacturers today. Research on the air volume and static pressure of the double fan range hood through theoretical analysis, simulation analysis and experimental analysis. The research shows that the maximum static pressure of the dual-fan range hood is similar and the maximum air volume is increased. However, under actual working conditions, the ability of the double-fan range hood to resist the resistance of the pipe network is slightly worse, resulting in an inability to effectively increase the air volume.

Key words: Range hood, Fan, Air volume, Static pressure
