What is the effect of the powerless air cap

Speaking of powerless air cap, I think many people do not know what it is, in fact, many families will now install powerless air cap, because you can through the powerless air cap will be indoor moisture, heat or dirty air and so on discharged to the outdoors, can be quite high indoor air circulation. But many people say that the powerless air cap is a scam, then how effective is the powerless air cap? Powerless air cap is suitable for home use? The following is our answer for you.

What is the effect of the powerless air cap?

Non-powered hood is the use of nature's natural wind speed to drive the fan turbine rotation and indoor and outdoor air convection principle, any parallel direction of air flow, accelerate and change to vertical air flow from the bottom up to improve the effect of indoor ventilation a device, it does not use electricity, no noise, can be a long time to run, to exclude the indoor heat, humidity and foul air.

The main common powerless air cap is divided into several situations, a mushroom-shaped small powerless air cap, a bell-shaped large powerless air cap, and then the "7" shaped guide powerless air cap, of course, there are a number of other different types of powerless air cap, such as umbrella, column and so on.

A small powerless wind cap is characterized by powerless wind cap aperture is smaller, better uniformity, but because of its design spacing is too small and lead to wear and tear phenomenon is more prevalent, coupled with the domestic fluidized bed of coal particle size is generally wide sieve, this wear and tear phenomenon is particularly serious. In addition, the air supply wind pressure will fluctuate in operation, resulting in the phenomenon of the bed material back to the air chamber, and the bed material back to the air chamber after the more will aggravate the wear and tear on the inner cavity of the non-powered air cap and the air outlet holes, the return of the bed material accumulated will also hinder the air supply through the flow, a serious threat to the safe operation of the boiler.

Second, the big powerless air cap is characterized by powerless air cap aperture is larger, to reach the critical fluidization after turbulence intensity is greater, the design of the spacing is larger, so it can effectively avoid the powerless air cap on the blowing caused by the wear and tear, but also because of the general use of labyrinthine design, so there is no basic bed material returned to the wind chamber phenomenon. Generally large powerless air cap service life is relatively long.

Non-power wind cap is a scam?

Non-powered hood is not a scam, but has certain advantages and disadvantages:

Non-powered hood's advantages:

1, no electricity, continuous operation of high efficiency and energy saving, no noise, no sparks, with explosion-proof.

2, wind and rain characteristics: circular blade, each blade and the gap between the blades, the rotation of the blades complement each other to fill the gap, a large amount of rain extended round the section line thrown out, the small is the rain is extended by the leaves and slices of the flow down to the roof, and will not flow into the turbine, and at the same time, rotating turbine so that the air from the blades gap out, blocking the rain to enter.

3, running device: the use of high technology standards of ball bearings, this bearing is completely closed, and always self-lubricating so that it can be less than 32km per hour under the breeze rotation.

4, dust: turbine exhaust fan is 24 hours non-stop rotation, dust is not easy to attach, even if you need to clean is also very convenient.

5, maintenance costs: rotary exhaust exhaust does not require maintenance, there is no need to replace parts to provide absolutely excellent quality, so the choice of no motor turbine fan is the investor's protection.

6, heavy star light: turbine exhaust installed on the roof with the base and count the total weight of about 15Kg / seat, quite light, in the design of the steel structure load, you can not need to consider.

7, lighting: blade and blade gap between the light will thus enter the room, can increase the degree of illumination 5-10% to save electricity.

8, powerless fan service life is long, generally can reach more than 15 years.

Disadvantages of non-powered hood:

1, because of the non-powered hood depends entirely on the natural wind, then some areas of the wind is small, the hood can not run normally, smoke effect is not good.

2, in our country, poor air quality in the region, often haze, so that inside and outside the air exchange of the air cap is easy to suck the polluted air from outside into the room, resulting in secondary pollution.

3, non-powered air cap work for a long time adsorption of a large amount of fumes, there may be rotation problems, hindering normal operation, or a lot of noise, producing heat to heat the air and other adverse effects.

The above is about the powerless hood is a scam details, in fact, the powerless hood is not a scam, because its use is still very good, but there are advantages and disadvantages, so some people will feel that the powerless hood is not suitable for home use, but some people think that the family installation of the powerless hood is still very good, so we still need to be based on the actual situation of their own families to see if they want to install the powerless hood. So we still need to look at the actual situation of their families to see whether to install a powerless hood.
