  • House DIY of ventilation
  •   House ventilation is very important, similar as our breathe, reasonable ventilation can make people live more comfortable and energy-efficient. There are many factors to effect the convection: location, housing shape and internal structure, the number of doors and windows, and doors and windows’ size, shape, location. Through comprehensive consideration to reach a reasonable configuration design.

      A brief introduction of several commonly method of ventilation that used in buildings.

    natural ventilation



    nature wind pressure to ventilate

    Wind tunnel test is shown that: when the wind blows to building, windward side of the building will generate a positive pressure, at the same time, each side and back will generate of a negative pressure。 Wind pressure ventilation is used the pressure different between building windward and leeward to effect air convection。 So, at a good clean areas environment, wind pressure ventilation is the main solution to effect air convection。




    natural hot air pressure to ventilate

    The principle is to use the different of up and down thermal pressure at inside the building---usually it is called ‘Stack effect’, drain off the dirty hot air at top of house, absorb clean air from the bottom of the house, in order to air convection.

    It is different from nature wind ventilation, thermal pressure ventilation can more adapt to the poor external environment。

    Ventilate with machine

    In larger buildings, because of the ventilation path is longer, larger flow resistance, not only depends on wind pressure and thermal pressure to ventilate. And there are ​​air and noise pollution in some area, ventilate directly will absorb the dirty air and noiseinto the indoor, that is not conducive to human health.

    In this case ,often using a mechanical-assisted natural ventilation system. the system has a complete air circulation channel, supplemented with air treatment means of ecological concept (such as soil pre-cooling, warm, deep well heat transfer, etc.), and with some mechanical way to speed indoor ventilation.

    Double-maintenance structure


    Double-maintenance structure

    Double-maintenance structure is the advantage technology that widely used in Ecological Building, hailed as “ can breathe skin” . Double-maintenance structure, generally composed of double glazing or triple glazing, between two layers of glass left in a certain width of laminated air gap formation, and is equipped with adjustable dark shutter. In winter, the air blanket and shutter uses of solar heated air to improve the exterior building wall heating; in summer, use the same principle to cool the exterior building wall temperature. It is more suitable for high-rise buildings, it is not only solved the interference of outdoor climate and noise that from the window and can safe ventilation in the nigh.

    Combination of wind pressure and thermal pressure
    Natural ventilation in housing design, combination of wind pressure and thermal pressure is better to achieve the best ventilation。 Usually, using wind pressure to ventilatein the smaller and deep parts of the house; using thermal pressure to ventilatein the bigger parts of the house。
