Do you know anything about the automatic ventilator for windows?

1) Ventilation and lighting, killing two birds with one stone.

The roof ventilator integrates ventilation and indoor lighting.

2) Save electricity.

It adopts non-powered design and uses the principle of aerodynamics to achieve the purpose of lighting and ventilation. Energy costs can be significantly reduced.

3) Strong waterproofing.

Reasonable waterproof design can prevent rainwater leakage while ensuring ventilation, lighting, smoke exhaust and noise reduction functions. Thin ventilators, such as the MCW1 ventilator, are widely used in practical cases and also make the ventilation and exhaust functions of the plant smoother.

4) Good wind pressure resistance.

In areas with strong winds, streamlined ventilators or thin ventilators can be used to reduce wind resistance and enhance the wind pressure resistance of the ventilator.

5) Anti-radiation performance.

In the hot summer, strong ultraviolet radiation can produce three hazards:

a. If the ultraviolet rays are too strong, the possibility of damage to the production line products increases;

b. Long-term exposure to ultraviolet rays endangers workers' health;

c. Exposed to sunlight for a long time, the temperature of the plant rises, which is not conducive to product production and can easily lead to mental fatigue of workers. However, roof ventilators can reduce these hazards.

6) Good environmental performance.

Due to changes in the environment, we propose to build a green society.

Whether it's natural ventilation or not, it's a chimney.

Originally, they were all cranks.

Now it's all electric.

Lifting glass. Or now many cars can do it: remove the key, close the door, lock the car, and if the window is not closed, it will automatically close.

What a car.

The simple one is the door glass regulator.

The complexity is a control unit, for example, if the door glass is not closed when the remote control car is locked, the control unit will automatically close the glass.

The automatic window riser is very simple, it is an intelligent electric device that automatically closes the glass window.

a. Application

After the car is turned off, when the owner leaves the car, it is controlled by the ECU of the automatic window raising (closing) device, and the window is automatically raised, which can prevent the owner from forgetting to close the window, and the second is to prevent theft.

b、mode

The automatic window lift (close) of the vehicle takes effect only after the car turns off the key and turns off the engine, and the operation is done once. There are three modes:

One isAfter the car key is turned off, the key is removed and the window is automatically closed;

The second isRemove the car key after the car key is turned off, close the driver's door, and automatically start to close the window;

The third isAfter the car key is turned off, and after the car door is closed, the window will automatically start to close when the remote control is pressed.

c、Basic Actions:

The driver's window, the passenger window, the passenger rear seat window, and the driver's rear seat window are closed sequentially.

The owner can freely choose according to his own requirements, and adjust the control line of each door of the window raising (closing) device in order.

d、Type:

, software control type

Program control type, generally due to the resistance of the door lifter, mud groove interference, etc., caused by misoperation, such as door A is not raised (closed), door B will be activated.

Intelligent

It is mainly controlled by the electronic module, and the detection function is completed by using the curing program in the host chip, so that the window closing step can be completed smoothly.

Integrated time and software control type

To prevent wrong operation, the lifting (closing) time of the previous door is appropriately extended, so as to achieve the complete lifting (closing) of the next door, and then carry out the lifting (closing) action of the next door. It is designed to prevent the motor from heating up and sticking for a long time, and the simultaneous operation of another motor to increase the load.

That is, you close the car door and press the key on the lock car building, if the glass is not closed, it can be automatically closed

Yes, it comes with insurance, which is harmless to the car, and friends in need in Beijing can go to see **-earn car dealership. Door-to-door installation.

It's convenient, and I don't know if it's harmful to the car.

I really don't know the cost, because the window closer at the time was included in the boutique when I bought the car. As for the folding key, if the landlord buys the luxury version, it is not recommended that the landlord change it, because the 10 luxury version has added an anti-theft chip, and it is more troublesome to change the folding key to destroy an original key, and some insurance companies must have two original keys when making a claim for part of the insurance.

Can be installed, just a hassle! It's not a good deal!!

It can be installed by simply scratching out a piece of glass to give the ventilator position. But the premise is that before the glass is installed, if it is a window that is already good, it will be more troublesome.

Hello, like the family side generally said that the installation of vacuum soundproof windows can achieve a good effect, vacuum soundproof windows are 900 yuan a square, four flat is 3600 yuan, plus a ventilator 800 yuan, wall-mounted ventilator is 1600 yuan. It can be installed within 15 days after the installation is completed.

Let's change the laminated soundproof glass windows. Hanks soundproof windows are currently available at a discount for individual households.

4 square meters, about the total cost of less than 3,000 yuan.

Make sure that your indoor noise is controlled below 40 decibels. Pay after installation, don't pay if you're not satisfied.

Install ventilators??? The installation of a ventilator will affect the sound insulation effect, how much does it cost to 4 square meters.

It depends on which soundproof window you install.

The difference is only a few hundred square meters.

Good more than a thousand a square.

This depends on what plan you choose, and it is different depending on the plan.

According to my personal experience, authentic American brands or American-spec cars only have one key to descend and no one to rise. This kind of thing that you changed later is easy to have problems after you change it, so you still have to think twice.

I bought it for more than 100 points, which is very easy to use, and it is in-line and does not need to be moved.

There is no need to plug in directly.
