1. Unreasonable design: Due to the expected saturation value of catering personnel being lower than the current saturation value during the opening and decoration, the workload of the kitchen increased, and multiple stoves were working simultaneously. The original design had low fan speed and low smoke exhaust volume, resulting in poor smoke exhaust. Solution: Install a four leaf or six leaf smoke exhaust fan at the smoke exhaust outlet, increase the smoke exhaust volume, or replace a high volume fan.

2、設計不合理：由于用餐人員的預期飽和值低于當前用餐飽和值，廚房工作量增加，多爐同時運行，原設計風機轉速低，排煙量小，排煙效果不好。解決方案：在排煙口安裝風機四葉或六葉排煙風機，增加排煙量，或更換高風風機。

2. Unreasonable design: Due to the expected saturation value of diners being lower than the current saturation value, the workload of the kitchen has increased, and multiple boilers are operating simultaneously. The original design has low fan speed, small smoke exhaust volume, and poor smoke exhaust effect. Solution: Install a four leaf or six leaf smoke exhaust fan at the smoke exhaust outlet, increase the smoke exhaust volume, or replace the high air fan.

3、設備老化:部分廚房設備中的老式排油煙設備排油煙罩老化，導致排氣罩漏氣，排煙量減少。排煙風機老化導致轉速降低，排煙量減少。老式排油煙設備的油煙管比較細(管徑約300mm*300mm)。由于油垢長期積累，不方便清洗，排煙效果也不好。

3. Equipment aging: Some kitchen equipment has outdated exhaust hoods, resulting in exhaust hood leakage and reduced smoke exhaust volume. The aging of the smoke exhaust fan leads to a decrease in speed and smoke exhaust volume. The oil fume pipe of the old-fashioned oil fume exhaust equipment is relatively thin (with a diameter of about 300mm * 300mm). Due to the long-term accumulation of oil stains, it is not convenient to clean and the smoke exhaust effect is not good.

4、設備老化:部分廚房設備中的舊油煙排放設備有老化的油煙罩，導致蓋子漏氣，排煙減少。排煙機老化導致排煙速度和排煙量減少。老油煙排放設備的油煙管比較細(管徑約300mm*300mm)。由于長期積累油污，清洗不方便，排煙效果差。

4. Equipment aging: Some kitchen equipment has old smoke exhaust equipment with aged smoke hoods, resulting in cover leakage and reduced smoke exhaust. Aging of smoke exhaust fans leads to a decrease in smoke exhaust speed and volume. The oil fume pipe of the old oil fume emission equipment is relatively thin (with a diameter of about 300mm * 300mm). Due to long-term accumulation of oil pollution, cleaning is inconvenient and smoke exhaust effect is poor.

此外，還有一些問題很容易被忽視，這也是更重要的一點，即加強鍍鋅螺旋風管加工安裝的維護和清潔工作，這也會影響鍍鋅螺旋風管加工安裝的排煙工作。

In addition, there are some issues that are easily overlooked, which is also a more important point, which is to strengthen the maintenance and cleaning work of galvanized spiral air duct processing and installation, which will also affect the smoke exhaust work of galvanized spiral air duct processing and installation.
