In many places in China, especially in large places of central air conditioning, the use of ventilation ducts is popular. They are the main parts for air circulation and helping the air conditioning to complete the operation. It is precisely because of this that we will process the ventilation duct when installing the air conditioner. Only in this way can we combine the ventilation duct with the air conditioner. However, before processing the ventilation duct, the following conditions need to be paid attention to.

其一：規格。這里所說的規格，就是通風管道的基本規格，我們所需要的通風管道的尺寸和大小。值得我們注意的是，在進行規格確定的時候，我們需要與空調的使用進行聯系，只有這樣，我們才能夠保證通風管道規格設定之后，能夠與空調相互連接，并發揮使用功能，完成它們的使用效果。

First: specifications. The specifications mentioned here are the basic specifications of the ventilation duct, and the size and size of the ventilation duct we need. It is worth noting that when determining the specification, we need to contact the use of air conditioner. Only in this way can we ensure that after the specification of ventilation duct is set, it can be connected with air conditioner, give play to the use function and complete their use effect.

其二：類型。通風管道的類型有很多種，不同的類型與空調進行聯合使用，所發揮出來的效果也不一樣，尤其是保溫性的通風管道。所以說，我們要想進行通風管道加工，且讓它們更好的結合空調進行工作，那么，我們也要在加工之前考慮下它們的類型，這是我們確保它們作業，發揮優勢作用的好條件。

Second: type. There are many types of ventilation ducts. Different types are used in combination with air conditioning, and the effect is also different, especially the thermal insulation ventilation duct. Therefore, if we want to process ventilation ducts and make them work better in combination with air conditioners, we should also consider their types before processing, which is a good condition for us to ensure their efficient operation and give full play to their advantageous role.

綜上情況來說，通風管道加工前，要與空調的基本情況相結合，并要注意通風管道的規格和類型，不同的空調需要不同的通風管道，規格不同，類型也不相同。所以在加工通風管道的時候，需要多考慮以上情況

To sum up, before processing, the ventilation duct should be combined with the basic situation of the air conditioner, and pay attention to the specification and type of the ventilation duct. Different air conditioners need different ventilation ducts with different specifications and types. Therefore, the above situations need to be considered when processing ventilation pipes
