When the fan system operates, the motor drives the fan blades to rotate to form negative pressure regions (relative to atmospheric pressure) on the front side and the rear side of the fan blades, and due to the existence of pressure difference, airflow enters an air duct channel which is formed by combining the volute casing and the volute casing cover and is used for discharging air from the upper portion and the lower portion, and then is conveyed indoors. The additional air inlet area formed by the installation part 2 is designed according to the structural form, so that the air quantity difference of a single-fan system relative to a multi-fan system can be effectively made up, and meanwhile, the utilization efficiency of the fan system is effectively improved.

When the single-suction centrifugal fan blade is adopted, airflow directly flows into the air channel from the flow guide ring on one side after passing through the heat exchanger, and the air beams at the inlet are concentrated; after the double-suction centrifugal fan blade is adopted, a part of air flow is additionally blown forward from the rear direction by the cavity near the volute, enters the front end of the double-suction centrifugal fan blade through the hollow-out area and the front side runner part of the mounting part 2, and then enters the air channel to flow indoors, namely, the principle of increasing the air volume is realized by adopting the combined form of the double-suction centrifugal fan blade and the hollow-out mounting part 2. Meanwhile, after the double-suction centrifugal fan blade is adopted, the purpose that the front side and the rear side are air inlet areas is achieved, the phenomena that the air inlet area is single and air flow is concentrated in the single-suction centrifugal fan blade are avoided, the uniformity of the air speed of the air inlet air flow can be effectively improved, and the efficiency of a fan system is improved.
