Fan is an effective air purification equipment, which can circulate indoor air. On the one hand, the indoor dirty air is discharged outside, on the other hand, the outdoor fresh air is imported through sterilization, disinfection, filtration and other measures, so as to keep the indoor fresh and clean at all times. The new fan adopts the patented technology of fresh air convection, which makes indoor air convection and replaces indoor air to the maximum extent through independent air supply and air introduction. The new fan has a built-in multifunctional purification system. The new fan is mainly divided into two types: exhaust fan and blower fan, which can be installed in most indoor environments with convenient installation and comfortable use. The new fan is a healthy companion of home life.
The working principle is basically the same as that of a general centrifugal fan. When the impeller rotates at high speed, all the air in the impeller is also driven to rotate together. At this time, the air in the center of the impeller will be thrown to the edge of the impeller because of centrifugal force, forming a vacuum in the center of the impeller. Therefore, under the action of pressure difference, the outside air will continuously flow in to supplement the center of the impeller, so that the fan has the ability to inhale. This is the basic working principle of dust removal fan.
Dust removal fan is a device to improve living environment and air convection. The household dust removal fan can suck away the dust blown in at home, prevent the human body from inhaling, and is beneficial to human health. Therefore, the working principle of dust removal fan is to restore a clean living space for people. No matter what brand of dust removal fan, we must abide by this principle for production.
Because the speed of air leaving the rotating impeller blades is much faster than the speed of air flow in the space around the impeller, some kinetic energy of gas is converted into static pressure energy during the movement. In the process of converting kinetic energy into static pressure energy, the space in the cover of the fan presents positive pressure, which enables the fan to transfer gas into the inlet. During the inlet, part of kinetic energy is converted into static pressure energy, which then flows into the motor, dissipates heat to the motor, and finally is pressed out through the outlet. This is the working principle of dust removal fan.
The dust removal fan adopts pollution-free heat recovery technology to realize the heat exchange between fresh air and exhaust air, reduce the indoor temperature loss caused by ventilation, be warm in winter and cool in summer, and save energy easily. The heat exchange efficiency is 70%~90%. The use of low-resistance filter can reduce the wind resistance to the maximum extent and reduce the burden of the fan, while the use of high-efficiency fan and frequency conversion adjustment technology can greatly reduce the power consumption, so that the power consumption of the fan is reduced by more than 40% compared with that of the conventional fan, which is truly energy-saving and environmentally friendly.
