With the rapid development of science and technology, people's requirements for the use of fans are getting higher and higher, according to the observation of the air conditioning and refrigeration market, at present, in terms of the development trend of foreign fan technology, it will develop in the direction of increasing fan capacity, high efficiency, high speed miniaturization and low noise.
The capacity of large wind turbines continues to increase. With the increasing scale of various industrial plants, the capacity of various types of fans is also increasing, and large fans will be welcomed in the market in the next few years and become more efficient. In order to improve efficiency, ternary flow impellers have been more and more widely used in ventilators. Other special-purpose fans such as diagonal flow fans will be more marketable.

The capacity of large blowers continues to increase. The increasing scale of various industrial plants objectively requires the capacity of various types of wind turbines, and large machine size fans will be welcomed in the market in the next few years.
Efficient. In order to improve efficiency, ternary flow impellers have been more and more widely used in ventilators. Other special-purpose fans such as diagonal flow fans will be more marketable. High-speed miniaturization. After the three-way flow impeller is used in various fans, the pressure can also be increased while improving the efficiency. Therefore, under the same conditions, the outer diameter of the impeller can be reduced by 10%~30%, so as to achieve the dual effect of reducing volume and weight. Increasing the speed is also one of the important ways to miniaturize the fan.
Reduced noise. Wind turbine noise is one of the most important sources of noise pollution in industrial production. The large size and high speed of wind turbines make noise problems very prominent. For low-frequency noise, the fan mainly improves the structural design of the fan to reduce the noise of the body, and if it does not meet the requirements, measures such as installing a muffler can be taken.
Through the above analysis, it is not difficult for us to find that the development direction of these technologies is not only the future development trend of foreign wind turbines, but also the direction of the domestic fan industry in terms of technology.
