Problems solved by technology

[0003] 1. The function of the air outlet is single, that is, the wind in the air duct is sent into the room, and the air supply volume is limited. If the air volume is too large, the wind noise of the air outlet will also increase
The shape of the tuyere only considers the situation of low wind speed, so it cannot adapt to the condition of high wind speed
[0004] 2. For places that require a large amount of air supply, the air outlet can only be enlarged, and a larger air supply outlet is selected, which has higher requirements for the installation location and conditions
In order to avoid the occurrence of high wind speed, we can only increase the size of the air outlet, which requires a large enough installation space, otherwise the air outlet and air duct cannot be installed normally, and the ideal air supply condition cannot be achieved
[0005] 3. The conventional tuyere has requirements for the temperature difference of the air supply. It is required that the air supply should not be too cold or overheated, which may easily cause problems such as condensation at the tuyere.
Conventional air outlets have certain applicability to the temperature difference between the supply air temperature and the required air supply area. The phenomenon of dew will affect the actual use effect
And the direct blowing of overcooled or overheated air also affects the comfortable experience

Embodiment

[0045] Such as Figure 1 to Figure 9 as shown,

[0046] An air supply increment type tuyere, comprising an air supply duct 1, an air inlet duct 2 and an air outlet 5, the air inlet duct 2 of the tuyere connected to the air supply duct 1, and the air inlet duct 2 below A tuyere body 3 is provided, and a flow equalization and expansion cavity 4 is arranged inside the tuyere body 3 , and a wind guide device is arranged between the flow equalization and expansion cavity 4 and the air outlet 5 .

[0047] Such as Figure 1 to Figure 4 As shown, the first embodiment of the present invention: the tuyere body 3 is a strip-shaped open structure, the inside of the tuyere body 3 is provided with a flow equalization and expansion cavity 4, and the flow equalization and expansion cavity 4 is divided into a flow equalization cavity 6 and an expansion space by a partition block 7. The pressure chamber 8, and the flow equalization chamber 6 is arranged near the air inlet duct 2 side of the t...

Embodiment 1

[0056] In Embodiment 1, the air outlet body 3 with a strip-shaped open structure will cause uneven pressure and uneven air supply volume due to direct air blowing after the throat enters the air, so it is necessary to equalize the flow and pressure to ensure uniform air supply. The air supply stroke in the tuyere body 3 of the bar-shaped open structure is relatively short, so an additional diffuser chamber 8 is added to ensure uniform air pressure of the air supply, that is, to play a buffering role. The tuyere body 3 of the annular closed structure in the second embodiment is relatively special. After the throat enters the air, the air supply first fills the entire annular inner cavity, and has enough stroke to convert the dynamic pressure into static pressure. Function, to achieve the purpose of equalizing flow and pressure and pressurization, to ensure uniform air supply, no need to set up a separate additional diffuser chamber.

[0057] In addition, the tuyere body 3 in th...

Abstract

The invention relates to an air supply increasing type air port. The air supply increasing type air port comprises an air supply air duct, an air port inlet air duct, an air outlet and an air direction diversion device, the air port inlet air duct is connected with the air supply air duct, an air port body is arranged below the air port inlet air duct, a current sharing diffuser cavity is formed in the air port body, and the air direction diversion device is arranged between the air sharing diffuser cavity and the air outlet. According to the air supply increasing type air port, the required installation space is small; large temperature difference air supply can be realized, and air port noise is effectively reduced; and the air direction diversion device can realize the wide angle area air supply, the air supply flexibility is higher, and the regional comfortable experience is improved.

Description

technical field [0001] The invention relates to the technical field of air management, in particular to an air supply increment type tuyere. Background technique [0002] Traditional air supply outlets are divided into louver type and diffuse flow type. The louver type is mostly direct blowing air supply, while the diffuse flow type is diffuse air supply. The air output of the air outlet is approximately equal to the actual air supply of the pipe. Generally, the wind speed of the air supply is low, the wind noise is large, and it is easy to condense and occupy a large space. Common problems in the air supply port in the prior art: [0003] 1. The function of the tuyere is single, that is, the wind in the air duct is sent into the room, and the air supply volume is limited. If the air volume is too large, the wind noise of the tuyere will also increase. The shape of the tuyere only considers the situation of low wind speed, so it cannot adapt to high wind speed conditions. ...
