Abstract

The invention discloses a natural ventilation system for a high-rise building, which comprises a plurality of rooms, an air intake window is arranged at the lower part of the outer wall of each room, and an exhaust window is arranged at the upper part of the inner wall adjacent to the corridor of each room, each of the The exhaust window communicates directly or through a horizontal pipe with the vertical air-introduction pipe. The bottom end of the air-induction pipe is closed. Air intake windows and exhaust windows, under the action of air pressure, fresh air is inhaled from the intake windows, discharged from the exhaust windows to the air duct, and then discharged vertically upwards from the air duct to the outside of the high-rise building, and the flow of air takes away the room. Inner exhaust gas, the wind cap is used to prevent water and objects from entering the air duct. The invention relates to a natural ventilation system for a high-rise building, which has the advantages of low cost, good ventilation effect, energy saving and environmental protection.

Description

High-rise building natural ventilation system

technical field

The invention relates to high-rise buildings, in particular to a natural ventilation system for high-rise buildings, which is used in high-rise building ventilation occasions.

Background technique

At present, there are more and more high-rise buildings, and the living density is relatively high. The ventilation problem in the rooms of high-rise buildings is becoming more and more prominent. In the prior art, the ventilation of each room of a high-rise building is either only ventilated by the windows in the room, or utilizes the central air conditioner to ventilate. It consumes electricity and makes the air unhygienic due to the inconvenient cleaning of the central air conditioner. the

Contents of the invention

The purpose of the present invention is to provide a natural ventilation system for high-rise buildings with low cost, good ventilation effect, energy saving and environmental protection.

To achieve the above object, the present invention can take the following technical solutions:

A natural ventilation system for a high-rise building of the present invention comprises a plurality of rooms, air intake windows are arranged at the lower part of the outer walls of each room, and exhaust windows are arranged at the upper part of the inner wall adjacent to the corridor of each room, and each of the exhaust windows The window is connected directly or through a horizontal pipe to the vertical air duct. The bottom end of the air duct is closed, and the top of the air duct protrudes from the top floor of the high-rise building and is provided with a hood. When the central air conditioner is not used, the air intake is opened. Windows and exhaust windows, under the action of air pressure, fresh air is inhaled from the intake window, discharged from the exhaust window to the air duct, and then discharged vertically upward from the air duct to the outside of the high-rise building, the flow of air takes away the exhaust gas in the room , The hood is used to prevent water and objects from entering the air duct.

Compared with the prior art, the beneficial effects of the present invention are: due to the adoption of the above-mentioned technical scheme, an air intake window is provided at the lower part of the outer wall of each room, and an exhaust window is provided at the upper part of the inner wall adjacent to the corridor of each room, and each room The exhaust window communicates with the vertical air duct directly or through a horizontal pipe. The bottom end of the air duct is closed, and the top of the air duct protrudes from the top floor of a high-rise building and is provided with a wind cap. When the central air conditioner is not used , open the intake window and exhaust window, under the action of air pressure, fresh air is inhaled from the intake window, discharged from the exhaust window to the air duct, and then discharged vertically upward from the air duct to the outside of the high-rise building. Exhaust the exhaust air in the room, and the wind cap is used to prevent water and objects from entering the air duct. This structure, using the air pressure difference, can efficiently and quickly discharge the exhaust air in the room without consuming electric energy, energy saving and environmental protection, low cost, and easy operation low cost.

Description of drawings

Fig. 1 is a schematic structural view of the present invention.

Detailed ways

As shown in Fig. 1, a kind of high-rise building natural ventilation system of the present invention comprises a plurality of rooms 1, is provided with air inlet window 2 at the bottom of the exterior wall of each room, is provided with at the interior wall top of the adjacent corridor 4 of each room Exhaust windows 3, each of the exhaust windows 3 on the right side is directly communicated with the vertical air induction pipe 5, and the exhaust window 3 on the left side is communicated with the vertical air induction pipe 5 through the horizontal pipe 6. The bottom end of air duct 5 is closed, and the top of air induction duct 5 stretches out the top floor of high-rise building and is provided with wind cap 8. Wind cap 8 is used to prevent water, thing from entering air-inducing pipe 5.

When the central air conditioner is not used, the air intake window 2 and the exhaust window 3 are opened. It is discharged straight upwards outside the high-rise building, and the flow of air takes away the exhaust gas in room 1.

Compared with the prior art, the invention has the beneficial effects of utilizing the air pressure difference to efficiently and quickly discharge the waste gas in the room without consuming electric energy, energy saving and environmental protection, low construction cost and low operating cost.
