If the preliminary design of the kitchen exhaust pipe is not reasonable, it is easy to have such a phenomenon, that is, after a period of time, the workload of the kitchen increases, multiple stoves operate at the same time, the original design fan rotation is low, and the exhaust volume is small, resulting in poor exhaust. Because the ventilation and smoke exhaust pipe is a large area of energy consuming equipment, from the perspective of energy saving, when designing and installing the ventilation and smoke exhaust pipe, we need to attach great importance to reducing the energy consumption of the ventilation and smoke exhaust pipe through reasonable design.

　　廚房的通風設備安裝是需要非常仔細認真的，要事先設計好，煙道從建筑結構設計來看由于有主、副煙道之分是不能隨意橫向改動的，否則會影響排煙并有倒灌的可能， 而為了美觀將煙道口上下移動則不會有不好的影響。

　　The installation of the ventilation equipment in the kitchen needs to be very careful and careful. The flue should be designed in advance. From the perspective of the architectural structure design, the main flue and the auxiliary flue can not be changed laterally at will, otherwise it will affect the smoke exhaust and have the possibility of backflow. In order to make the flue move up and down in order to be beautiful, it will not have a bad impact.

　　隨著經濟的快速發展，通風管道在生活生產中也是不能夠忽視的，像是飯店里，因為有了通風設備才能夠為消費者提供良好的用餐環境，讓更多的人來飯店吃飯，對于工業生產中，像是礦產開采中，更需要良好的通風條件以此來改變工作環境，保障礦工們的呼吸健康。現在通風的設備、越來越受到重視。所以我們一定要重視其通風管道的事先設計工作，只有設計工作做好了，以后才能讓排煙管道安心為我們工作。

　　With the rapid development of economy, ventilation pipes can not be ignored in life and production. For example, in a hotel, only ventilation equipment can provide a good dining environment for consumers, so that more people can eat in the hotel. For industrial production, such as mining, good ventilation conditions are more needed to change the working environment and ensure the respiratory health of miners. Kang. Now, more and more attention has been paid to ventilation equipment. Therefore, we must pay attention to the design of the ventilation pipe in advance. Only when the design work is done well, can the smoke exhaust pipe work for us safely.
