酒店廚房排煙罩設計安裝方法：

Design and installation method of smoke exhaust hood in hotel kitchen:

1、廚房排煙罩安裝的墻體，它的構造和材料都應該要有足夠的強度。排煙管、風管的外墻開口，可采用砌筑預制帶洞混凝土塊或預埋鋼管留洞方式。保溫墻(要用空心磚)與正常墻壁的安裝方法一樣，如果墻面不夠結實的話，那么就要用木板或其他材料進行加固。

1. The structure and materials of the wall for the installation of kitchen smoke exhaust hood should have sufficient strength. The exterior wall opening of smoke exhaust pipe and air duct can be built with precast concrete block with hole or embedded steel pipe. The installation method of thermal insulation wall (hollow brick shall be used) is the same as that of normal wall. If the wall is not strong enough, it shall be reinforced with wood board or other materials.

2、廚房排煙罩安裝的煙管直接穿過外墻至室外，應該在室外排氣口設置防止污染環境和避風的構件。共用豎向煙道連接的吸油煙機，它的豎向煙道的斷面應根據所負擔的排氣量計算確定。

2. The smoke pipe installed in the kitchen smoke exhaust hood directly passes through the outer wall to the outside, and components to prevent environmental pollution and shelter from wind shall be set at the outdoor exhaust port. For the range hood connected by the common vertical flue, the section of its vertical flue shall be calculated and determined according to the exhaust volume.

3、廚房排煙罩安裝頂吸式的安裝高度應該在燃氣爐灶上方至少65厘米的地方，在65-75厘米之間是比較合適的

3. The installation height of the top suction type of the kitchen smoke exhaust hood should be at least 65 cm above the gas stove, and it is more appropriate between 65-75 cm

一：將油煙機管道通過吊頂接入煙道口。

1： Connect the pipe of the range hood to the flue opening through the ceiling.

注意事項：

matters needing attention:

1、首先需要檢查煙道口是否有吊頂下移而在上部所預留的空間和位置的條件。

1. First of all, it is necessary to check whether there are conditions for the space and position reserved at the upper part of the flue opening due to the downward movement of the ceiling.

2、吊頂之前將煙機排煙管預埋進吊頂上部，需要根據櫥柜的設計圖紙來確定排煙管在吊頂上外露口的位置，需要參照的還有煙機的款式，一般說歐式煙機的管道是在中間位置，而中士煙機的排煙管口卻在煙機的一側。這些情況影響著預留口的位置。

2. Before the ceiling, the smoke exhaust pipe of the ventilator is embedded into the upper part of the ceiling. The position of the exposed opening of the smoke exhaust pipe on the ceiling needs to be determined according to the design drawing of the cabinet. It also needs to refer to the style of the ventilator. Generally speaking, the pipe of the European ventilator is in the middle position, while the smoke exhaust pipe opening of the sergeant ventilator is on one side of the ventilator. These conditions affect the position of the reserved opening.

3、在預埋排煙管時注意封閉住煙道口的縫隙，并保證其牢固不脫落。

3. When embedding the smoke exhaust pipe, pay attention to close the gap at the smoke passage and ensure that it is firm and does not fall off.

4、如果灶具安置在陰臺一側，就需要注意排煙管道是否通過樓房的過梁的問題，原則上物業管理部門是不允許在過梁打孔穿越排煙管的。這種處理方式1可以不必考慮煙道口與墻壁之間的距離，避免了因為煙道口距墻的距離大于吊柜的進深而影響到吊柜的安裝，2可避免完成安裝后吊柜頂部留有一段橫向煙機排煙管而影響美觀。

4. If the stove is placed on one side of the shade platform, it is necessary to pay attention to whether the smoke exhaust pipe passes through the lintel of the building. In principle, the property management department is not allowed to punch holes through the smoke exhaust pipe in the lintel. This treatment method 1 does not need to consider the distance between the flue outlet and the wall, which avoids affecting the installation of the hanging cabinet because the distance between the flue outlet and the wall is greater than the depth of the hanging cabinet. 2 it can avoid leaving a section of transverse smoke exhaust pipe on the top of the hanging cabinet after installation, which affects the appearance.

5、此種方式不可避免的會在吊頂與煙機上部露出部分上下走引的管道，朋友們可根據這個管道的位置和高度設計包管板等來加以修飾。此種方法利于排煙的通暢和整體布局的美觀。

5. In this way, it is inevitable that the pipes leading up and down will be exposed in the ceiling and the upper part of the smoke machine. Friends can design the guarantee plate according to the position and height of the pipe. This method is conducive to smooth smoke exhaust and beautiful overall layout.

二：吊頂緊貼廚房頂部，利用吊頂和吊柜頂部之間的空當橫向引走排煙管。

2： The ceiling is close to the top of the kitchen, and the space between the ceiling and the top of the hanging cabinet is used to lead the smoke exhaust pipe laterally.

注意事項：

matters needing attention:

1、吊頂與吊柜頂部之間是否有走引排煙管道的條件。煙道口的位置高于吊柜頂部.煤氣表主管位置不存在障礙等。

1. Whether there are conditions for leading smoke exhaust pipes between the ceiling and the top of the hanging cabinet. The position of the flue outlet is higher than the top of the hanging cabinet There are no obstacles at the main pipe of the gas meter.

2、煙道口外部邊緣距離后墻不超過吊柜柜體的進深，以便吊柜安裝完畢后用封頂板將排煙管封閉住。如果此處留有煤氣感應器，需要將煤氣感應器引出安置在適當的位置。

2. The distance between the outer edge of the flue opening and the rear wall shall not exceed the depth of the cabinet body, so that the smoke exhaust pipe can be sealed with a capping plate after the installation of the cabinet. If there is a gas sensor left here, the gas sensor needs to be led out and placed in an appropriate position.

三：排煙管道通過吊柜柜體進入煙道。

3： The smoke exhaust pipe enters the flue through the cabinet body.

注意事項：

matters needing attention:

1、煙道口要安排在吊柜柜體高度與進深厚度之內，具體尺寸以上下煙口邊沿2000-2200之間為佳，煙道口外沿與后墻的距離不大于250為宜。以保證在安裝完吊柜時排煙管在煤氣表及煤氣管道前部能有足夠的空間走引排煙管。

1. The flue opening shall be arranged within the height and depth of the hanging cabinet. The specific size is better between 2000-2200 above the edge of the lower flue opening, and the distance between the outer edge of the flue opening and the rear wall shall not be greater than 250. To ensure that there is enough space for the smoke exhaust pipe to lead the smoke exhaust pipe in front of the gas meter and gas pipeline when the hanging cabinet is installed.

2、中式煙機因為上部通常有柜體，排煙管有空間走引，歐式煙機不適合此種方式，原因是歐式煙機上部通常不做柜體，如果需要采用此種方式，需要加高兩側吊柜，使歐式煙機上部與吊柜頂部能有管道走引的空間，并在歐式煙機上部設計為封閉處理，以避免排煙管道下垂繞行，影響排煙效果和視覺美觀。不論采取哪種方式，設計上都使排煙管自然順暢，達到良好的排煙效果。

2. Because the upper part of the Chinese range hood usually has a cabinet and the smoke exhaust pipe has space for guiding, the European range hood is not suitable for this method. The reason is that the upper part of the European range hood usually does not have a cabinet. If this method is needed, the hanging cabinets on both sides need to be raised so that there is space for pipeline guiding between the upper part of the European range hood and the top of the hanging cabinet, and the upper part of the European range hood is designed for closed treatment, To prevent the smoke exhaust pipe from sagging and bypassing, affecting the smoke exhaust effect and visual beauty. No matter which way is adopted, the design makes the smoke exhaust pipe natural and smooth to achieve good smoke exhaust effect.
