How does the ac forward curved centrifugal fan work?

The AC forward curved centrifugal fan, also known as the AC forward curved blower, operates based on the principle of centrifugal force generated by the rotating impeller.

Here’s a breakdown of how it works:

1. Impeller Design: The AC forward curved centrifugal fan consists of a circular impeller with multiple curved blades that are forward-facing. The impeller is connected to a motor shaft, which drives its rotation.

2. Air Intake: The fan draws in the surrounding air through an inlet or suction opening located at the center of the impeller. As the impeller rotates, the curved blades capture the incoming air and direct it outward.

3. Centrifugal Force: As the air moves radially outward due to the curved blades, it experiences a centrifugal force. This force causes the air to change direction, moving from the axial direction (along the axis of rotation) to the radial direction (perpendicular to the axis).

4. Air Acceleration: The curved blades of the impeller accelerate the air as it moves outward. This acceleration increases the air velocity, resulting in a higher pressure at the outer edge of the impeller.

5. Air Discharge: The high-pressure air is then discharged from the impeller into a scroll or volute-shaped housing surrounding the impeller. The scroll housing gradually expands and allows the air to be directed in a specific direction or into a duct system.

6. Airflow and Pressure: The AC forward curved centrifugal fan generates a relatively high airflow at a relatively low pressure. The forward curved blades are efficient in moving a large volume of air while overcoming the resistance to airflow.

7. Motor Operation: The fan is powered by an AC motor, which provides the necessary rotational energy to drive the impeller. The motor is typically designed to operate at the required voltage and frequency of the AC power supply.

The AC forward curved centrifugal fan is commonly used in HVAC systems, air handling units, ac forward curved centrifugal fan and other applications that require moderate to high airflow with relatively low pressure requirements.
