The expansion steps of smoke exhaust ducts can basically be divided into familiar graphics, shape analysis, finding the real length of a straight line or the real shape of a plane, determining the expansion method, and drawing the expansion diagram. Before carrying out unfolding and cutting, it is necessary to familiarize oneself with the construction drawings. This is a preparatory work, mainly to have an understanding of the key and components to be unfolded, such as the size of the pipeline on the drawings, manufacturing materials, etc. For more complex pipe fittings, it is necessary to repeatedly read and analyze the construction drawings, and timely raise and solve relevant problems. Due to the fact that ventilation pipe fittings and their components are geometric shapes on drawings, the main purpose of analyzing the shape is to simplify complex geometric shapes. Through analysis, in order to find an appropriate deployment method.

廚房通風排煙對于酒店廚房來說是必不可少的，如果酒店廚房失去通風排煙系統，那么廚房的工作環境將會變得非常差，甚至不能忍受，工作效率就會變得大打折扣。所以酒店廚房安裝通風排煙系統的意義非同小可，而且在選擇安裝酒店廚房窗臺煙系統的時候，一定選擇優質的通風排煙系統，不可大意。

Kitchen ventilation and smoke exhaust are essential for hotel kitchens. If the hotel kitchen loses its ventilation and smoke exhaust system, the working environment in the kitchen will become very poor, even unbearable, and work efficiency will be greatly reduced. So the significance of installing a ventilation and smoke exhaust system in a hotel kitchen is significant, and when choosing to install a window sill smoke exhaust system in a hotel kitchen, it is important to choose a high-quality ventilation and smoke exhaust system and not be careless.

避免管道內空氣熱損失，還可以阻止熱量散發到房間內讓室溫升高，避免人接觸風道被燙傷。在夏季因輸送氣體溫度低于周圍環境空氣露點溫度，管道外壁會結露。這對集中空調系統的風道會加大冷量損失，同時凝結水滴會污染吊頂和墻地面，因此也應該進行保冷隔熱處理，其實對于通風管道安裝施工來說，對于我們生活中的重要性我們都知道，尤其是一些人在購房時也會考慮一下通風效果怎么樣，房子在構建初期就會設計好各管道的位置，叁金來通風設備為人們擁有良好的生活品質做保障

Avoiding heat loss from the air inside the duct can also prevent heat from radiating into the room, causing room temperature to rise, and preventing people from getting burned in contact with the air duct. In summer, due to the temperature of the transported gas being lower than the dew point temperature of the surrounding air, the outer wall of the pipeline will condense. This will increase the cooling loss of the air ducts in the centralized air conditioning system, and condensate droplets will pollute the suspended ceiling and wall floor. Therefore, cold insulation treatment should also be carried out. In fact, for the installation and construction of ventilation ducts, we all know the importance in our daily lives, especially when purchasing a house, some people will also consider the ventilation effect. In the early stages of building construction, the position of each pipeline will be designed, Sanjinlai ventilation equipment ensures a good quality of life for people
