Types of exhaust duct vents:

　　1. 活動百葉窗(雙層數(shù)百頁的風口通常用作送風口,也可以直接使用風機盤管,廣泛應用的空調(diào)系統(tǒng),也可以打開多用調(diào)節(jié)閥調(diào)節(jié)風量。單層百葉風口可上下風向調(diào)節(jié)，回風可配合風口過濾器使用，節(jié)流閥角度可調(diào)節(jié)，葉片之間有ABS塑料固定支架。清洗時可將固定過濾器從滑塊上取下，清洗后推入滑塊內(nèi)繼續(xù)使用。

　　1. Movable louvers (double hundreds of pages of air outlets are usually used as air outlets, but also can directly use fan coil units, widely used central air conditioning system, can also open multi-purpose control valves to regulate air volume. Single-layer louver tuyere can adjust the direction of upper and lower air, return air can cooperate with tuyere filter, throttle valve angle can be adjusted, ABS plastic fixed bracket between the blades. When cleaning, the fixed filter can be removed from the slider and pushed into the slider to continue using.

　　2、自閉百葉(自閉百葉式風口有正壓空調(diào)室自動排風。通常依賴于風口百葉窗式的自重和自然下垂,隔離室內(nèi)和室外空氣交換,當室內(nèi)空氣壓力大于室外空氣的壓力,空氣會吹百葉窗和排氣,相反,室內(nèi)空氣壓力低于室外空氣的壓力,不能逆轉的氣流進入室內(nèi),風口有單向檢查效果。

　　2. Self-closing louver (self-closing louver with positive pressure air conditioning room automatic exhaust air). Usually depends on the self-weight and natural sag of the tuyere louver, isolating the air exchange between indoor and outdoor. When the indoor air pressure is greater than the outdoor air pressure, the air will blow the louver and exhaust. On the contrary, the indoor air pressure is lower than the outdoor air pressure, and the irreversible air flow enters the room. The tuyere has one-way inspection effect.

　　3.風口控制閥(擴散器控制閥、卷簾風口控制閥)

　　3. Tuyere control valves (diffuser control valves, curtain tuyere control valves)

　　4. 固定百葉(側墻格柵風口，開側墻格柵風口)

　　4. Fixed louvers (side wall grille vent, side wall grille vent)

　　5. 風口過濾器(鋁合金過濾器、鋼網(wǎng)過濾器)

　　5. Tuyere filter (aluminium alloy filter, steel mesh filter)

　　6. 防雨百葉風口(單層防雨百葉、雙層防雨百葉、自掛防雨百葉)

　　6. Rain-proof louvers (single-layer, double-layer and self-hanging louvers)

　　7. 擴壓器(方形、矩形擴壓器、lfk-7動葉縫擴壓器、條狀直擴壓器、平葉擴壓器)

　　7. Diffuser (square, rectangular diffuser, lfk-7 movable blade gap diffuser, strip diffuser, flat blade diffuser)
