Automatic ventilator adopting corridor wind energy

Abstract

The invention discloses an automatic ventilator adopting corridor wind energy. The automatic ventilator comprises a fan blade, a rotating shaft, a fan blade outer frame device and a limiting device for limiting the maximum swinging angle of the fan blade; the rotating shaft is arranged on one side of the central axis of the fan blade and is mounted inside the fan blade outer frame device; and thefan blade is mounted inside the fan blade outer frame device by the aid of the rotating shaft. By the aid of the automatic ventilator adopting the corridor wind energy, a room can be ventilated efficiently and actively by the aid of the corridor wind energy only, corridor wind can enter the room efficiently regardless of the wind direction, no electric energy or chemical energy is consumed in thewhole process, and all the required energy is the wind energy in the nature.

Description

technical field [0001] The invention relates to the field of building ventilation, in particular to a corridor wind energy automatic ventilating fan for efficiently and actively ventilating a room by utilizing the corridor wind energy. Background technique [0002] Corridor air is a general term for moving air that flows between two buildings or in a corridor. At present, in order to enhance the ventilation effect of the building, its outer contour will not be a flat plane, and a certain groove is often built as an air duct. On the one hand, the Brownian motion of the air in the groove can be used to assist indoor ventilation. On the other hand, the pressure generated by the corridor wind on the air in the groove is used to assist indoor ventilation. The actual effect of this method of assisting indoor air exchange by utilizing the air channel formed by the groove and by means of the flow of natural air is very poor. And in most cases, the angle between the wind direction ...

AI Technical Summary

Problems solved by technology

The actual effect of this method of using the air duct formed by the groove and using the flow of natural air to assist the indoor ventilation is very poor

And in most cases, the angle between the wind direction of the corridor wind and the plane where the window wall is located is not large, even 0 (that is, parallel). The angle between the plane and the plane where the window wall is located is close to 0 (approximately parallel). At this time, pushing the window door can not change the air flow into the room; Although the windows and doors can be opened to a certain direction to draw the wind into the room, the purpose cannot be achieved when the wind direction changes, unless the direction of opening the windows and doors is manually changed; therefore, it is not easy for the corridor wind to enter the room automatically from the windows of the current buildings

Since the indoor ventilation flow is not large in the natural state, it is often necessary to turn on the exhaust ventilation fan, but this will increase the power consumption, which is not conducive to energy conservation and environmental protection
