1. By connecting the smoke exhaust duct through the upper part of the suspended ceiling, this method does not need to consider the distance between the flue outlet and the wall, effectively avoiding installation problems when the distance between the smoke exhaust duct is greater than the depth of the ceiling cabinet. However, in such installation, it is important to pay attention to the following two points:

是要檢查煙道口的吊頂安裝條件：由于吊頂需要進行下移,所以要考慮上部預留的空間和位置是否具備安裝的條件;其次預埋排煙管道時可能會有縫隙，要注意封閉好,以保證管道不會脫落;2、廚房排煙管道可以采用吊柜柜體方式進入設置，這種方法是一種很常見的廚房排煙管道布置方法，這用到的管道也比較少，當然依然要注意幾點：

Firstly, it is necessary to check the installation conditions of the suspended ceiling at the flue outlet: as the suspended ceiling needs to be moved downwards, it is necessary to consider whether the reserved space and position on the upper part meet the installation conditions; Secondly, there may be gaps when embedding smoke exhaust pipes, and attention should be paid to sealing them properly to ensure that the pipes do not fall off; 2. The kitchen smoke exhaust duct can be set up through the use of hanging cabinets and cabinets. This method is a common layout method for kitchen smoke exhaust ducts, and the number of ducts used is relatively small. Of course, there are still several points to pay attention to:

(1)直徑為2.0~2.2m的管道，煙道口外沿與墻的距離不要超過250mm，因為這樣才能保證安裝完吊柜后排煙管在煤氣表、煤氣管道前有足夠的空間;(2)相對于歐式油煙機來說，這種布置方式與中式抽油煙機更搭配，因為中式煙機的上部通常都有吊柜柜體，而歐式煙機上部通常不做柜體。所以通常不存在引走管道的空間。

(1) For pipes with a diameter of 2.0-2.2m, it is best not to exceed 250mm from the outer edge of the flue opening to the wall, as this can ensure that there is sufficient space for the exhaust pipe in front of the gas meter and gas pipeline after the installation of the hanging cabinet; (2) Compared to European range hoods, this arrangement method is more suitable for Chinese range hoods because the upper part of Chinese range hoods usually has a hanging cabinet body, while the upper part of European range hoods usually does not have a cabinet body. So usually there is no space to lead pipes away.

3、利用吊頂與吊柜間的空間來接入排煙管道，這種排煙管道設置方法是適用吊頂緊貼廚房頂部戶型裝修方式，主要是采用吊柜頂部和吊頂之間的空檔橫向引走排煙管道，也有這樣的幾點要注意：

3. Using the space between the suspended ceiling and the suspended cabinet to connect the smoke exhaust duct, this method of setting the smoke exhaust duct is suitable for the decoration method of the ceiling closely adhering to the top of the kitchen. The main method is to use the gap between the top of the suspended cabinet and the suspended ceiling to horizontally lead the smoke exhaust duct. There are also several points to note:

(1)廚房排煙管道煙道口的位置必須高于吊柜的頂部，要確保吊頂與吊柜之間有足夠的空間;(2)煙道口外部與墻面的距離不能超過吊柜柜體的進深，因為吊柜安裝完畢后需要用封頂板將排煙管道封住，如果距離不夠操作不方便。

(1) The position of the smoke exhaust duct outlet in the kitchen must be higher than the top of the ceiling cabinet, ensuring sufficient space between the ceiling and the cabinet; (2) The distance between the outside of the flue outlet and the wall should not exceed the depth of the ceiling cabinet body, because after the installation of the ceiling cabinet, it is necessary to seal the smoke exhaust pipeline with a sealing plate. If the distance is not enough, it is not convenient to operate.
