Abstract】:As the saying goes, the central air conditioning is a three-part product, seven part installation. It can be seen that for the central air conditioning project, the installation is very important, which can be said to affect the use effect in the future. So, summed up some key points about the construction of central air conditioning, let's take a look.

As the saying goes, central air conditioning is three products, seven points of installation. Visible to central air conditioning project, the quality of installation is very important, can be said to affect the use effect in the future. Then, summarized about central air conditioning project construction in a few main points, have a look together.
