Abstract
The invention relates to a natural ventilation device in a high rise building, which is characterized in that the roof of the high rise building is provided with an air pulling tower communicated with an air pulling well; the air pulling well is communicated with a plurality of rooms in the high rise building via suction pipes; the top of the air pulling tower is in a circular arc shape; and a plurality of air outlets are arranged below the top. When airflow flows through the circular-arc top of the air pulling tower, flow rate is quickened; according to the Bernoulli principle, pressure is lowered, and air in the air pulling well is sucked and is discharged from the air outlet; negative pressure in the air pulling well causes air in the room to enter the air pulling well via a pipeline; meanwhile, outdoor air is supplemented into the room via an air inlet; and the operation is continuously carried out like this, the room can continuously obtain fresh air under the condition that the window is closed, and dirty air is discharged. Compared with the prior art, the natural ventilation device has the beneficial effects on consuming no electric power and causing no noise.
Description
Affiliated technical field
The invention belongs to technical field of buildings, particularly a kind of air interchanger that is applied in high-rise.
Background technology
Present high-rise, a kind of suction type VMC (see figure 4) is generally adopted in indoor such as residential building or office block.Just electronic air exhausting device is extracted indoor air out through exhaust tube 1, causes indoor negative pressure, and simultaneously outdoor fresh air replenishes from air inlet 2 and gets into the indoor of negative pressure.So can be to the indoor air displacement of carrying out under the situation of not windowing.The shortcoming of this VMC is an electronic air exhausting device electric consumption around the clock, secondly is that the noise of electronic air exhausting device also lets the people not feel well.Therefore, above-mentioned compound ventilation air-changing device haves much room for improvement.
Summary of the invention
In order to address the above problem, the purpose of this invention is to provide a kind of not consumes electric power, and do not have the air draft mechanical noise, rely on natural wind on the high-rise roof to carry out the facility of indoor air-changing.
The present invention is achieved in that it comprises the room that contains air inlet and exhaust tube in the high-rise; Be characterized on the high-rise roof, being provided with a gas pulling tower; Gas pulling tower pulls out gas well and is communicated with one, pulls out gas well and is communicated with the interior a plurality of rooms of high-rise through exhaust tube; The top of gas pulling tower is circular arc, and the below, top is provided with a plurality of gas outlets.
Method for using of the present invention is: when air flow stream was crossed the top of gas pulling tower circular arc, flow velocity was accelerated, and pressure reduces, and the air that pulls out in the gas well is pumped up, and discharges through the gas outlet; And the negative pressure of pulling out in the gas well makes the air in the room pull out gas well through the pipeline entering, and outdoor air adds in the room through air inlet simultaneously.So constantly operation makes the room under the situation of not windowing, constantly obtain fresh air, discharges foul atmosphere.
The present invention's beneficial effect compared with prior art is:
1, consumes electric power not utilizes natural airflow to take a breath.
2, there is not noise.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the partial enlarged view B of Fig. 2.
Fig. 4 is the room sketch map that contains air inlet and exhaust tube in the high-rise.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described further:
One gas pulling tower 3 is set on the high-rise roof, and gas pulling tower 3 pulls out gas well 4 and is communicated with one, pulls out gas well 4 and is communicated with the interior a plurality of rooms of high-rise through exhaust tube 1; The top 31 of gas pulling tower is circular arc, and the below, top is provided with a plurality of gas outlets 32.
When air flow stream was crossed the top 31 of gas pulling tower circular arc, flow velocity was accelerated, and according to bernoulli principle, pressure reduces, and the air that pulls out in the gas well 4 is pumped up, and discharged through gas outlet 32; And the negative pressure of pulling out in the gas well 4 makes the air in the room pull out gas well 4 through exhaust tube 1 entering, and outdoor air adds in the room through air inlet 2 simultaneously.So constantly operation makes and constantly obtains ventilation in the room.
Claims (2)
1. the natural ventilator in the high-rise; Comprise the room that contains air inlet and exhaust tube in the high-rise; It is characterized in that on the high-rise roof, being provided with a gas pulling tower; Gas pulling tower pulls out gas well and is communicated with one, pulls out gas well and is communicated with the interior a plurality of rooms of high-rise through exhaust tube; The top of gas pulling tower is circular arc, and the below, top is provided with a plurality of gas outlets.
2. the method for using of the natural ventilator in the high-rise as claimed in claim 1 is characterized in that when air flow stream is crossed the top of gas pulling tower circular arc, and flow velocity is accelerated, and pressure reduces, and pulls out the interior air of gas well and is pumped up, and discharges through the gas outlet; And the negative pressure of pulling out in the gas well makes the air in the room pull out gas well through the pipeline entering, and outdoor air adds in the room through air inlet simultaneously.So constantly operation makes the room under the situation of not windowing, constantly obtain fresh air, discharges foul atmosphere.
