Every day there are more and more new devices that are created in order to facilitate human life. One of these is a fanless fan. This unit is an innovative product and relates to climate control devices. It turned out that the appearance of this device on the market was appreciated by customers, because it is safe, economical and easy to use. In this article we will consider how a fan works without blades, its types, advantages and disadvantages.
The principle of operation of the fan without blades
The design of these devices does not give a complete picture of how it works. It looks like a simple design: a ring is attached to the supply through which a powerful air stream passes. Let's look at the principle of operation of a fan without blades.
Air passes through the air intake and exits from the reverse side at high speed. The aerodynamic design creates low pressure for the purpose of rolling air flows at the inlet. The turbine is built in the footboard, at the exit creates a rapid air flow. This unusual design makes it much more efficient than a fan with blades.
This device is safe because there are no rotating elements in it, so you can not be afraid to leave it in a place visible to children. If there are pets at home, then nothing is threatening them either.
At the footboard is a mechanism by which the ring can be rotated 90 degrees to the sides, and the angle of inclination is also changed by 10 degrees. The comfort of using a bladeless fan is increased due to the rotation option by 360 degrees. Due to this, the zone of distribution of cool and fresh air increases. Management simplifies the remote control.
Vaneless fans pass about 500 liters of air per second. At the exit, air is distributed evenly. When creating this device, developers took as an example the operation of a conventional jet engine of an airplane.
