How to design aluminum doors and Windows to achieve good natural ventilation?
Designing doors and Windows to achieve good natural ventilation requires consideration of a number of factors, including window type selection, window opening location, number and size of doors and Windows, building spacing and layout. Here are some specific design suggestions:
First, window type selection
Windows with different opening methods have different ventilation effects. Generally speaking, the ventilation effect of the sliding window is better than that of the casement window, and the casement window is better than the internal inverted window and the upper suspended window. Casement window If you want better ventilation, you can choose a 180 degree open window sash. Because of its design characteristics, the sliding window can maximize the opening of the vent area, thus providing better ventilation.
Second, window opening position
Staggered position: Let the two doors and Windows located on the opposite wall in a staggered position, so that the ventilation path of the doors and Windows can cover every corner of the room well to achieve better ventilation.
Multiple Windows: If you want fresh air to fill the whole room, you should open more than two Windows and stagger the positions, such as one on the front and the other on the side.
Third, the number and size of doors and Windows
Quantity: Determine the number of window sashes according to the indoor area. Under normal circumstances, when the ratio of the vent area to the floor area is 5% to 10%, the room can obtain better ventilation. For example, it is enough to open one or two Windows in bedrooms and bathrooms, and at least two or more Windows should be opened in large areas such as living rooms.
Size: The size of the window also needs to be reasonably designed according to the size of the room. Larger rooms should be designed with larger Windows to ensure adequate ventilation area.
Fourth, building spacing and layout
Building spacing: In the planning and design of residential areas, appropriate building spacing should be ensured in order to create good natural ventilation conditions. If the building spacing is too small, it will affect the sunshine and ventilation effect.
Overall layout: Reasonably control the overall layout of the building, so that the direction of the building and the summer dominant wind direction to form a certain Angle, conducive to the introduction of natural wind. At the same time, the building depth and the length of the bay also need to be appropriate to reduce the influence of eddy currents on the ventilation effect.
5. Other design points
Window design: The design of Windows should take into account the smoothness of air flow. For example, you can optimize the airflow path by setting up wind deflectors or adjusting how Windows are opened.
Gold gauze mesh: If the window is installed with gold gauze mesh, it should choose a style with moderate mesh and easy disassembly to ensure that it does not affect the ventilation effect and can play a role in insect protection.
To sum up, the design of doors and Windows to achieve good natural ventilation needs to start from many aspects, including window type selection, window opening location, number and size of doors and Windows, building spacing and layout. Through scientific and reasonable design and layout, natural wind resources can be fully utilized to improve indoor air quality and residential comfort.
Natural ventilation environment: When designing doors and Windows, it is also necessary to consider the local natural ventilation environment. For example, in areas where the dominant wind direction is obvious in summer, more natural wind can be used to achieve indoor ventilation and cooling.
