Diagonal Flow Duct Fan High Static Pressure Capacity Analysis and Its Application in Air Conditioning Systems

1. Importance of High Static Pressure Capacity
In air conditioning systems, static pressure is a key indicator to measure whether the fan can effectively overcome the resistance of the duct. Factors such as bends, corners, and resistance of vents in the duct will cause air flow obstruction. In order to ensure the smooth operation of the air conditioning system, the fan needs to have sufficient static pressure capacity to push the air through these ducts and equipment with high resistance.

Due to its oblique impeller design, the diagonal flow duct fan not only allows the air flow to flow axially inside the fan, but also generates a certain amount of rotational motion. This design enables the fan to generate higher static pressure in a smaller volume. This makes the diagonal flow duct fan an ideal air flow delivery device in air conditioning systems, especially suitable for air conditioning systems that require long-distance air delivery or high static pressure environments.

2. High static pressure design of diagonal flow duct fans
The high static pressure capacity of diagonal flow duct fans comes from their unique design structure. Unlike traditional centrifugal fans, the impellers of diagonal flow duct fans are arranged at an angle, the airflow rotates on the impeller surface, and a higher static pressure is generated at the fan outlet. This design reduces energy loss in air flow and improves the airflow delivery efficiency of the fan.

Through the fine design of parameters such as impeller angle, number of blades, and blade surface treatment, diagonal flow duct fans can find the balance between small size and high efficiency, thereby providing high air flow while maintaining low noise and low energy consumption. This design makes diagonal flow duct fans particularly suitable for long-distance transportation and high static pressure requirements in air-conditioning systems.

3. Application advantages in air-conditioning systems
In air-conditioning systems, pipeline systems often need to cope with complex design requirements, especially long-distance transportation, multiple air outlet distribution, and high-resistance pipelines. The high static pressure capacity of diagonal flow duct fans enables them to perform well in such complex environments. Specifically, the high static pressure capacity of diagonal flow duct fans gives them obvious advantages in the following applications:

3.1 Overcoming pipeline resistance
In air-conditioning systems, especially central air-conditioning systems in large buildings, air is often transported for a long time and over a large area. Elbows, branches and vents in the duct will cause large air resistance, and traditional fans often find it difficult to effectively overcome these resistances. The high static pressure capacity of the diagonal flow duct fan can easily deal with these problems, ensuring that the airflow can be stably and smoothly transmitted to the air conditioning terminal equipment, avoiding the phenomenon of poor airflow or insufficient air volume.

3.2 Adapt to high-load operation
The diagonal flow duct fan can not only provide high static pressure, but also has strong stability in its design, and can continuously provide stable airflow under high-load operation. This makes the diagonal flow duct fan very suitable for air-conditioning systems with large load fluctuations, especially places such as commercial buildings and industrial plants that require flexible temperature control.

3.3 Adapt to complex pipeline layout
In air-conditioning systems, especially multi-story buildings or places with complex pipeline networks, the pipeline layout is often irregular, and may include complex forms such as multiple bends, branches and diameter changes. The high static pressure capacity of the diagonal flow duct fan enables it to adapt to these complex pipeline layouts and overcome the uneven airflow distribution caused by pipeline resistance, ensuring uniform ventilation of the air-conditioning system.

4. Energy saving and high efficiency
The high static pressure capability not only ensures that the diagonal flow duct fan can meet the performance requirements of the air conditioning system, but also makes it more energy efficient. In applications that require higher static pressure, the diagonal flow duct fan can maintain high air flow and pressure output at low energy consumption. By adopting advanced variable frequency speed regulation technology, the fan can automatically adjust the operating speed according to the real-time needs of the air conditioning system, thereby saving energy when the load is low and still providing sufficient air volume when the load is high.
