AC fans are the most widely used products of home electric appliances. The W4D400-DP12-40 AC fan is an energy-saving product and has wide applications. This paper will discuss its application field and working principle.

Application Field: The W4D400-DP12-40 AC fan is mainly used in residential air-conditioning systems, food refrigeration systems, car air-conditioning systems, commercial refrigeration systems and other environments which require ventilation. With its superior energy-saving feature, it is especially suitable for small and medium-sized refrigeration systems. In addition, due to its excellent performance and long service life, it is also used in some noise-sensitive environment.

Working Principle: The W4D400-DP12-40 AC fan is driven by an AC voltage of 220v-415v. When power is supplied, the dielectric in the fan is magnetized, generating a rotating magnetic field. The fan cone is installed with permanent magnets, and the rotating magnetic field interacts with the permanent magnet. Thus, a centrifugal force is generated to drive the fan cone to rotate. The air flow generated by the centrifugal force is pumped out of the fan and delivered to the environment.

The fan is designed with adjustable blade angles to increase its performance and energy efficiency. When the fan is running, the blade angle of the fan could be adjusted for different air volume requirements. For higher air volume requirement, the blade angle is adjusted to a smaller size, and vice versa. The W4D400-DP12-40 AC fan also features with an adjustable rotation speed and an anti-electromagnetic interference design. Therefore, it is capable of producing high air volume with lower noise emission.

In conclusion, the W4D400-DP12-40 AC fan is a reliable and energy efficient product. It can be applied to various environments which require ventilation and air conditioning. Furthermore, the adjustable blade angle and rotation speed make the fan capable of producing different air volumes with minimum noise emission. Therefore, it is an ideal solution for small and medium-sized residential, commercial and car air conditioning systems.
