【 Building materials network 】For ventilation and budget saving, how many fans should be opened in a room? For these problems - Suifu doors and windows Explain clearly by combining what you hear, see and hear.

1、 For civil building design, there are standards for opening fan ventilation

1. The building shall be set with outdoor air that directly circulates with indoor air according to the use function and indoor environment requirements window Or hole; When it is impossible to set external windows or openings, additional ventilation facilities shall be provided.

2. For spaces with direct natural ventilation, the effective area of ventilation openings shall meet the following requirements:

(1) The effective area of ventilation openings in living and working rooms shall not be less than 1/20 of the floor area of the room.

(2) The effective area of ventilation openings in the kitchen shall not be less than that of the room floor 1/10 of the area, and not less than 0.6 ㎡.

(3) The air inlet and outlet openings shall not be located in areas with poor ventilation, and short circuit of air flow at the air inlet and outlet openings shall be avoided.

(4) In general, Sliding window Its height is about 0.5m-1.5m, and its width is 0.6-1.0m. The sliding window within this range will be relatively suitable and safer.

(5) Considering the floor safety factors, the sash width of the outward window should be ≤ 650mm, the sash height should be ≤ 1200mm, and the opening weight of the outward window should not exceed 50KG.

2、 The ventilation effect and cost shall be considered for the number of open windows

The ventilation effect of the room is closely related to the window type, window opening position and window opening direction. The window type affects the ventilation, and good window opening position and direction can Other doors The window generates convection to accelerate the flow of wind; In the same case, although more fans can increase the ventilation volume, it is not wise to pursue ventilation volume alone.

The number of open doors and windows should be determined according to the size of the indoor area. When the ratio of vent area to floor area reaches 5%~10%, a better ventilation effect can be achieved in the room. That is to say, one open window in a general room is enough to meet the indoor ventilation demand, while the living room with a slightly larger space only needs two open windows to meet the demand. Too many open fans will also increase the cost of home decoration (and sometimes affect the appearance), which is a waste of money and not good looking. It is obviously thankless for those with insufficient budget.

3、 The ventilation effect is not only related to the opening fan, but also the window type

Outward opening window, sliding window, inward opening inward reversing window, rotating window, outward opening upward Suspended window ... Each window type is suitable for home use, but its ventilation size is different. Generally speaking, the smaller the opening angle, the smaller the effective ventilation area. Therefore, the ventilation effect is quite different in different opening modes: sliding windows Casement window >Open inward and invert inward>top hung window.

If the daily requirements for ventilation are high, Suifu Doors and Windows recommends that you choose the bridge cutoff sliding window series. The sliding window has a large opening area, is easy to open, and is suitable for ordinary families; If it is matched with Broken Bridge Aluminum profile , the thermal insulation effect of the whole window will be improved.

If you want good ventilation in your home, it is not enough to choose the right window type. Whether doors and windows can play their inherent ventilation effect is also related to their location. In addition to the excellent conditions of facing south from north and being transparent from south to north, there should be no obvious obstacles (such as walls, indoor partitions, etc.) between doors, windows, and air inlets and outlets of buildings, or it will hinder natural ventilation from flowing indoors and affect air convection. In addition, the window opening can be done according to the layout of the home. Generally, the window opening position is suggested to be on the side of the bed, sofa, etc.

4、 Mosquito prevention with open fan screen window Coordinate with window opening and ventilation

The common screen mesh is mostly made of high-strength stainless steel wire through heavy precision looms. Its crisscross structure (0.8mm thick wire diameter) not only can prevent mosquitoes from protecting privacy, but also has good anti prying and anti shearing capabilities. But it should be understood that the finer the screen is, the better the privacy, but not the ventilation.

Users who need mosquito prevention, privacy prevention and ventilation can choose folding type gauze nets. Folding and opening can ventilate, and closing can prevent mosquitoes, which is convenient for both.

▲ The picture comes from the network

Suifu doors and windows provide more options for home ventilation. Suifu door and window casement window series not only have single casement mode, but also have opening and closing modes such as inward opening and inward turning, outward opening and outward hanging, micro ventilation, manual folding screen, etc. The window series hardware fittings are imported products, which can be opened smoothly and flexibly; A variety of opening methods are practical and flexible, providing you with more options for frequent window opening and ventilation.

Sound insulation, let people experience; Safe and reassuring; Commitment gives people confidence! Behind every door and window is the persistence and persistence of our Suifu door and window craftsmen, which is also the interpretation of quality life. Choose doors and windows, choose safety and choose brands: With careful door and window brands, Suifu doors and windows will naturally give you peace of mind in choosing, buying and using.
