What is a ventilated skylight? 20

Improve the air inside the car.

After opening the sunroof, it can accelerate the air flow in the car, keep the upper air in the car fresh, and keep the driver awake and relaxed throughout the driving process.

Purify the gas inside the car.

The working principle of the car sunroof is negative pressure ventilation, and the air flow on the roof of the vehicle flows rapidly to form negative pressure in the car during driving, and sucks out the dirty air in the car.

Fog can be eliminated.

When driving on the road in the rainy season or in the winter when the temperature difference between indoor and outdoor is large, if the side windows are closed, it is easy for fog to appear in the car and attach to the front windshield, in this case, the fog can be quickly eliminated by opening the sunroof.

Reduce noise distractions.

When driving on the road, the interior of the car is disturbed by the noise of the lane and surrounding vehicles, and if the sunroof is opened, the noise is reduced while ventilating.

Cooling and energy saving. If the vehicle is equipped with a sunroof, you only need to open the sunroof and use negative pressure ventilation to suck out the hot air in the car during driving. This method also saves energy consumption from cooling the air conditioner.

Ventilation skylights are divided into industrial plant skylights, commercial building skylights, residential building skylights and automobile skylights.

The main functions of skylights are ventilation, smoke exhaust, lighting, ventilation, etc.

The one overhead, there's also a panoramic skylight.

Basic Functions:Ventilation, lighting, smoke exhaustIf the plant has a thermal insulation function, an open-closed ventilation skylight can be used.

The ventilation skylight is a streamlined structure, with reasonable layout, smooth air circulation, no dead angle area, and low flow resistance, which can effectively prevent outdoor air backflow and rain and snow penetration.

Advantages of designing roof ventilation skylight: ventilation skylight is a streamlined structure, reasonable layout, smooth air circulation, no dead angle area, small flow resistance, can effectively prevent outdoor air backfill, can effectively prevent rain and snow penetration.

The main thing is the role of ventilation and heat dissipation, which is how I understand it.

Through it, we can eat the most effective effect is ventilation, and there is a feeling that may be more high-end atmosphere.

1. The wind pressure difference formed by the wind force realizes the circulation of air. The windward side of the plant is determined by the building form and wind direction, and usually the dominant wind direction in summer is the windward side. When the wind blows towards the building, the building has a blocking effect on the wind, creating positive pressure on the windward side and negative pressure on all sides of the building, and the pressure difference between the two is the key to achieving ventilation.

2. The thermal pressure difference caused by the difference between indoor and outdoor temperatures helps to achieve natural ventilation of the building. Using the principle of hot air rising, an exhaust outlet is set up in the upper part of the building to discharge the dirty hot air outside, and the outdoor fresh and cold air is inhaled from the air inlet around the building, so as to achieve the purpose of exchanging air and purifying the indoor space. The hot pressure effect is related to the height difference between the exhaust outlet and the air inlet and the temperature difference between indoor and outdoor, and the greater the height difference between the exhaust outlet and the air inlet and the temperature difference between indoor and outdoor, the more obvious the hot pressure effect.

The working principle of the ventilation skylight is actually very simple, that is, heat dissipation, remove moisture and mildew in the plant, keep the factory dry, and the ventilation skylight replaces the effect of the roof heavy-duty fan, and realizes the better ventilation effect of the specific gravity fan, and the dehumidification effect is also very good.

1.The ventilation skylight is mainly composed of peripheral protection plate, skeleton, valve plate, opening and closing mechanism, flashing plate, rain shield and other parts. Installed at the reserved opening on the roof of the building, the reserved opening is consistent with the size of the throat of the ventilation skylight, and the ventilation skylight with a larger throat size or installed at the ridge usually needs to be fixed with a base.

2.The main working principle of ventilation skylight is that the indoor temperature is higher than that of outdoor due to production activities, personnel gathering and other reasons, and the hot air rises to eliminate outdoor ,..

3.The ventilation skylight can be installed at the ridge or along the roof, and can be installed along the slope of the ridge.

"The working principle of ventilation skylights is to ventilate according to the temperature difference between indoor and outdoor. Generally, the indoor is relatively warm, especially in many factories because there are a lot of mechanical equipment running, and there are many factories that use heating equipment, so the temperature difference between them and the outdoors is relatively large. The density of the hot gas is relatively low, so it will continue to rise, and eventually it will be discharged by the ventilation skylight.

So at this time, the air pressure in the room is relatively small, so.

"The working principle of ventilation skylights is to ventilate according to the temperature difference between indoor and outdoor.

In order to make full use of the top floor or attic and make the indoor environment more comfortable, many people will install some skylights on the roof, but many people don't know much about skylights, so what is a skylight? Let's find out with me.

1. What is a skylight?

The so-called skylight actually refers to the installation of a glass window on the roof of the top floor or attic, so that the indoor lighting effect and ventilation effect are improved, and become brighter and spacious. In addition, the dryness of the indoor air can be appropriately improved, so as to create a comfortable living environment for the owners.

Second, what should be paid attention to when installing sunroofs.

1. Lighting and ventilation.

When installing the skylight, be sure to pay attention to the thermal insulation effect of the skylight, because the skylight is located on the roof, so it will generally be directly exposed to the sun, and it will be very hot inside. In order to ensure the comfort of the indoor temperature, we should try to choose materials with good thermal insulation when installing skylights.

2. Waterproof. When installing a sunroof, be sure to pay attention to the waterproof effect of the sunroof. Because the skylight is located on the roof, if the waterproof effect of the skylight is not good, once it rains, the rainwater will directly enter the room, causing the owner's economic loss.

In order to avoid these problems, it is necessary to do a good job of waterproofing the skylight, and all the indoor roofs should be waterproofed, along the skylight and there should be no gaps, and at least twice should be waterproofed, so as to ensure that there will be no problems even in bad weather.

3. Design. When installing the skylight, be sure to pay attention to whether the design of the skylight is in line with the decoration style of the attic or the top floor. The skylight should not only provide good ventilation and lighting effect for the interior, but also need to match the interior decoration style.

The above is a detailed introduction to what is a sunroof and what should be paid attention to when installing a sunroof, I hope it can help those friends who need to install a sunroof. Skylights should not only provide good ventilation and lighting for the interior, but also match the interior decoration style.

At present, as an important design of housing construction, skylights have two main uses: one is ventilation; The second is lighting. This article will focus on the knowledge of ventilation skylights and mountain branches through two aspects: classification and form, characteristics and benefits.

Ventilation skylights are divided into two categories: sunken and upward, and their advantages, disadvantages and forms are as follows:

1) Sunken ventilation skylight.

The sunken ventilation skylight makes full use of the space of the roof truss, makes it into a roof with staggered heights, and creates a vertical plane at the drop of the roof for ventilation and lighting. In general, the advantages of this kind of skylight are to reduce the weight of the roof, save indoor space and have a good wind shelter effect, but there are also problems such as easy to produce rain and dust.

If it is divided according to the structure, the sunken ventilation skylight can be divided into the following three forms:

Well-type skylight The well-type skylight is formed by moving the local roof panel down to the lower chord of the roof truss, which has a better ventilation effect, but the drainage and ash cleaning work is more troublesome. Longitudinally sunken sunroof.

This form of skylight is formed by the longitudinal length of the roof panel of the sunken part along the roof and resting on the roof truss, and the ventilation effect is also very good, but in the structure, part of the roof truss is exposed to the outdoors, and the waterproof structure should be dealt with. Horizontal sunken skylight.

The transverse sunken skylight is formed by laying the roof panel of a column foot under the roof truss every one or several column spacing, and once the span is too large or multi-span, the wind shelter performance will be relatively poor.

2) Upward-facing ventilation skylight.

The top-bearing ventilation skylight is to erect skylight frames, wind shield brackets and wind shields and other components on the roof of the factory, and most of the gutters are set up at the top of the skylights, which have the functions of lighting and ventilation. The overall advantage is that it is easy to carry out drainage and ash cleaning operations, but there are also defects of complex structure, increased weight and investment of the roof and easy to leak rain

Rectangular sunroof, M-shaped sunroof.

Both forms of skylights are supported on the roof truss, and the skylight frame is lit and ventilated on both sides of the skylight frame. Serrated sunroof.

On the zigzag sloping roof, skylight glass is mostly installed on the north-facing side.

In addition, there are other forms of ventilation skylights, which will not be listed due to space limitations. Benefits::

Whether it's a public construction project or a private house renovation, ventilated skylights have extremely obvious benefits:

For public buildings:

1) Beautiful appearance, high ventilation efficiency, good rain, snow and wind shelter performance;

2) The structure is light in weight, easy to design, select, and construct and install, especially suitable for the construction of light steel structure;

3) Diversification of varieties, reasonable design and construction, and wide application;

4) The use of new materials, new technologies, new processes, strong professionalism, with high market value.

For private houses:

1) Good ventilation effect, remove indoor humidity, stuffiness and odor and improve air quality;

2) Good lighting ensures the openness of the field of vision, which is conducive to breaking the depression of the confined space;

3) It has both practical value and decorative value: it not only has the function of ventilation, but also has a beautiful and generous design.

<> sunroof is a device installed on the roof of the car, and the sunroof glass can be lifted and opened by manual or motor drive, and has the functions of ventilation and lighting and heat dissipation.

Window on the roof for ventilation and light.

The skylight is lit and the ventilation efficiency is high. There are many kinds of applications in modern architecture, according to their structure, location and relationship with the roof, they can be summarized into three categories: zenith type, convex type and concave type.

In order to support the roof skylight, the structure should be drained to set up beams; roof rainwater, skylight room should be left to the gutter. Zenith effect skylight, uniform and light, flexible in arrangement, simple in structure, but it should be noted that it protects against glare, solar radiation, condensation and falling glass. If non-safety glazing is used, the roof below is located under a metal protective net.

To prevent glare, a grating set consisting of a skylight can be used. To prevent condensation from droplets, here you can set the opening of the water and drain groove.

Typhoon is used in two forms, ventilation, exterior wall windows for lighting, lighting and ventilation using internal openings. Flushing skylights are made up of warm air at the top of the mountain, the shutters, so that the hot air washes off directly; Side-mounted window frames, aided breathing, plus a cover in case of wind and rain. Dried tofu with indoor temperature fluctuations, the temperature sensor drives the hydraulic device, the angle of self-opening, adjusts the amount of ventilation, the rainwater can pass through the rainwater sensor and related facilities, and close the blinds, while opening the side windows, to maintain the necessary ventilation.

The flushing sunroof is light, small in size, flexible, more capable, efficient, and suitable for high temperature and strong radiation in hot and smoking shops.
