In many places in our country, especially in large places of central air conditioning, the use of ventilation pipes is the most popular. They are the main parts for air circulation and air conditioning to complete the operation. It is also because of this, when we install the air conditioner, we will process the ventilation duct, only in this way can we combine the ventilation duct with the air conditioner. However, before the processing of the ventilation duct, the following should be noted.

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。

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

Second, type. There are many types of ventilation duct, different types of combined with air conditioning, the effect is not the same, especially the insulation of the ventilation duct. Therefore, if we want to process ventilation ducts and make them work better with air conditioning, then we should also consider their types before processing, which is a good condition for us to ensure that they work efficiently and play a dominant role. To sum up, before the processing of the ventilation duct, it is necessary to combine it 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, in the processing of ventilation duct, need to consider the above situation.
