The HVAC market is constantly updated with new offers. These include bladeless fans. These devices quickly aroused interest among potential buyers, which was accompanied by some doubts. A bladeless fan often surprises with its appearance and functionality. Not surprisingly, consumers have many questions that need to be dealt with.
Some buyers decide on such an acquisition, others are worried that the money will be spent in vain. To get rid of all these doubts, it is necessary to understand the performance of such equipment, to find out its device, the principle of operation and the rules of operation. Only then can concrete conclusions be drawn.
Device structure
The main elements of a bladeless fan include:
- annular diffuser;
- the base of the device;
- high speed turbine;
- engine.
This is quite enough for the device to work effectively. A high-speed turbine was installed in the engine, which in turn is installed in the base of the device. When the fan turns on, the turbine begins to move air. To get rid of excess noise that can be emitted by the engine, a special Hemholtz chamber is used. It will pick up and dissipate noise. As a result, the fan will not disturb the surrounding people.
A sufficient number of holes have been made in the case, which allows air to be sucked in. In the upper part there is an aerodynamic ring with an annular diffuser. The presence of a sufficient number of holes allows you to blow air. Often the ring is used in different forms. It can be a circle, an oval, a rhombus, even a heart. The designers of the manufacturing plant tried to diversify such products using different options.
Features of the bladeless fan
Functioning is in many ways similar to a jet engine. There is a similar turbine with which air is circulated. It is installed in the fan leg and operates silently. During operation, with the help of holes, it is possible to achieve not only cooling for air filtration. The turbine pump is capable of efficiently pumping up to 20 cubic meters of air per second. A conventional fan cannot cope with such a task, which makes the device so popular.
Air masses will pass through the distribution ring, which has an empty cavity where a gap is present. The air speed reaches 90 km /.At these rates, one air flow meets another, which allows it to create air flow compensation. Due to this, the outgoing air will increase several tens of times. When choosing a bladeless fan, you must choose a trusted manufacturer that guarantees the quality of the device. In this case, you can count on long-term operation and the creation of an optimal microclimate in the room.
