What is the use of the ball on the roof?

The ball on the roof of the building has the effect of purifying the air, and the appearance design of the ball is very reasonable, similar to a ball.

The ball on the roof is blown by the natural wind to continuously replace the indoor and outdoor air to achieve the effect of purifying the air.

I think it can be lightning protection, because if there is thunder and lightning, then the building can be prevented from being electrified.

He uses the blowing of the natural wind to promote the power of the fuselage itself, so that the indoor and outdoor air can be replaced, so as to achieve the effect of purifying the air.

The full name of the metal ball rotating on the roof of the building is "unpowered ventilator", and in the south, it is also called "hood of wind signal". Its main function is to replace the air, that is, to discharge the indoor heat, oil smoke, moisture and other gases to achieve the effect of improving the indoor air.

The surface of the non-powered ventilator is made of stainless steel, so it is not easy to be corroded, and it also has the effect of preventing snow and ice dew, even if some foreign objects fly, it is not easy to fall in. What's even more amazing is that the unpowered ventilator does not need to be electrically driven, and can operate automatically through air circulation. During the working process, no noise is generated.

And the installation is very simple, and it is not easy to break down during use. In addition to this, the unpowered ventilator has a protective function. If the home is **, or the corridor is **, the non-powered ventilator can speed up the air flow, so that the indoor smoke can be quickly discharged, giving people trapped in the house more opportunities to escape.

What is the use of the "ball" on the roof?

In everyday life, there are some things that we are very common, but we don't know what they do. For example, we often see metal balls in factories or high-rise buildings, do you know what this thing is for? Today, let's unveil the mystery of this little thing and read the long knowledge!

Now the roof of the factory will be installed on a round hat device, but also will rotate, this little thing is called a non-powered hood, everyone is used to calling it a ventilation ball, as the name suggests, this thing is for ventilation. This ventilated ball does not need to be plugged in, nor does it need to burn oil, and it mainly rotates by the wind. Its function is the same as that of the expensive fresh air system, which is to ensure the ventilation of the building, and constantly replace the hot air inside and the fresh air outside from the gap between the blades of the metal ball.

This kind of ventilation ball has a simple structure and low cost, so it is popularized by the public. It consumes very little energy and is neither plugged in nor burned with oil, so it can be said to be zero cost for daily use. We often see these metal balls in some factories or farms, rotating on the roof one by one, in order to effectively solve the problem of poor air circulation.

Some careful friends found that the whole body of this metal ball is basically a hole, so there is a question of a closed mind high, will it leak when it rains on the roof? I would like to tell you with great certainty that the answer is that it does not leak. The surface blades of the ventilator are very dense, the material is very smooth, and the openings are designed so that rainwater does not flow into the crevices.

Whenever it rains, the rainwater is drained to the roof by the smooth surface and then flows downward.

It can be seen that such a good thing is simple and inexpensive, no wonder it is loved and widely used by everyone. When you see this thing on the road, you'll know what it's for.

The ball on the roof of the high-rise building is made of stainless steel, which uses the blowing of the natural wind to push the turbine of the fan itself to rotate, so that the indoor and outdoor air can be replaced, and the effect of air purification is achieved. The ball is not a closed ball, it is composed of a fan blade, the blade is arc-shaped, and the gap between the blades can be covered when blown by the wind. <

Rainwater and dust will not fall into the "ball", and it is easy to maintain the cleaning effect itself, and it is more convenient to clean up.
