1、格柵風口橫條和豎條鑲嵌在一起，不分層，不能帶調(diào)節(jié)閥，格柵風口在外觀上有點像雙層百葉風口，不同的是，格柵的格子是固定的，橫豎格子在一個面上，比較美觀。格柵風口適用于要求不高的一般空調(diào)工程，一般用在空調(diào)回風、機械通風的送回風、消防補風上。

2、而百葉風口分單層百葉風口、雙層百葉風口橫豎百葉在前后兩個面上，都可以調(diào)節(jié)角度。沒有格柵風口美觀，排煙口，正壓送風口，機械送排風等，根據(jù)是否需要調(diào)節(jié)等因素選用風口類型。百葉風口適用于一般精度工程，均可作為送回風口。3、百葉風口用處較多，幾乎所有需要風口的地方都可以使用，百葉風口分電動、手動兩種。手動一般在空調(diào)通風系統(tǒng)圖中使用，電動在消防正壓送風中使用。百葉風口送風高度一般不超過4米。

4、還有自垂百葉式風口一般用于樓梯口加壓送風，防雨百葉風口用于一般用于室外，室內(nèi)風口一般是格柵風口用于排煙較多，單百葉用于排風送風較多，空調(diào)用雙百葉較多，回風口一般是用帶濾網(wǎng)的百葉風口。但具體使用一般看業(yè)主和現(xiàn)場情況要求定

5、單層的只能上下調(diào)節(jié)風向，雙層可以上下左右調(diào)節(jié)風向。但在實際使用中，雙層出風口有它的缺點，如噪音問題、難清潔問題等，而且中央空調(diào)出風口一般也無必要調(diào)節(jié)風向。

1, grille, tuyere stripes and bar set together, no separation, cannot take the regulator, grille tuyere in appearance is a bit like double shutter tuyere, the difference is that the grille lattice is fixed, the relation grid on a surface, more beautiful. Grille tuyere is suitable for the request is not high general air conditioning engineering, commonly used in air conditioning air return, mechanical ventilation to the wind, fire protection air make-up on.

2, but the single louvers shutter tuyere tuyere, double shutter tuyere shutter on the both before and after, can adjust the Angle. No grille tuyere is beautiful, exhaust port, positive pressure air supply outlet, mechanical exhaust, etc, according to factors such as whether to need to adjust tuyere type. Shutter tuyere applicable to the general precision engineering, all can be used as back to the tuyere. 3, louvers tuyere use is more, almost all need to tuyere can use, electric, manual shutter tuyere points two kinds. Commonly used in air conditioning and ventilation system graph manually, electric used in fire positive pressure air supply. Shutter tuyere air supply is generally not more than 4 m.

4, and the vertical Venetian tuyere is commonly used in stair pressurization, rainproof shutter tuyere for commonly used in outdoor, indoor tuyere is grille tuyere in smoke more commonly, a single shutter used to exhaust air distribution is more, the air conditioning with double shutter is more, return air mouth is generally with mesh shutter tuyere. But the specific use generally see the owner and site condition requirements

5, monolayer can adjust up and down the wind, double can regulate the direction of the wind up and down or so. But in actual use, double outlet has its drawbacks, such as noise problem and difficult to clean, and the central air-conditioning outlet generally do not need to adjust the direction of the wind.
