In many places of our country, especially in large places of central air conditioning, the use of ventilation ducts is the most popular. They are the main parts for air circulation and help the air conditioning to complete the operation. 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 ventilation pipes, the following conditions should be paid attention to.

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

One: specifications. The specifications mentioned here are the basic specifications of ventilation ducts, the sizes and sizes of ventilation ducts 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 ventilation duct is set, it can be connected with air conditioning, and play the use function to complete their use effect.

其二：類型。通風(fēng)管道的類型有很多種，不同的類型與空調(diào)進行聯(lián)合使用，所發(fā)揮出來的效果也不一樣，尤其是保溫性的通風(fēng)管道。所以說，我們要想進行通風(fēng)管道加工，且讓它們更好的結(jié)合空調(diào)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(yè)，發(fā)揮優(yōu)勢作用的好條件。

Second, type. There are many types of ventilation ducts. Different types of ventilation ducts combined with air conditioning have different effects, especially the heat preservation ventilation ducts. Therefore, if we want to process ventilation ducts and make them work better with air conditioning, 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 advantages.

綜上情況來說，通風(fēng)管道加工前，要與空調(diào)的基本情況相結(jié)合，并要注意通風(fēng)管道的規(guī)格和類型，不同的空調(diào)需要不同的通風(fēng)管道，規(guī)格不同，類型也不相同。所以在加工通風(fēng)管道的時候，需要多考慮以上情況。

To sum up, before the processing of ventilation duct, it should be combined with the basic situation of air conditioning, and pay attention to the specification and type of ventilation duct. Different air conditioners need different ventilation ducts, with different specifications and types. So in the process of ventilation pipe, need to consider the above situation.
