Central air conditioning is generally used in homes and enterprises, and the installation of central air conditioning also has high process requirements. As a senior central air conditioning maintenance practitioner, I would like to explain the installation precautions and common knowledge sharing to the customers who are about to buy, hoping to help you with your purchase and installation.

First, what is the specific installation method of central air conditioning

1, central air conditioning host. That is, the installation of outdoor units. The host of the central air conditioning is generally installed outdoors, and there is a separate place to install the host outside. The installation method of the outdoor host of the central air conditioning is basically the same as that of the outdoor host of our ordinary air conditioning.

2, central air conditioning pipeline. Central air conditioning is divided into refrigerant system and water system according to different refrigeration methods, which is the central air conditioning of copper pipe and galvanized steel pipe that we usually see. But no matter what kind of air conditioning needs to be arranged pipes. Among them, there are cooling pipes and condensate drainage pipes, which need to be arranged along the position below the top plate, all the way to each splitter, that is, the fan coil.

3, the end of the central air conditioning. That is, the machine that blows cold air and hot air in our room, commonly known as the fan coil. The machine in this position is directly the installation of the ceiling or is hung on the beam for installation, and the end is to hide all the above equipment through the ceiling, and what we can see is the louver mouth of the wind.

Second, what is the specific form of the roof of the building

1, we need to know that all the roof of the building is a structural floor. This kind of structural floor is to bear a certain load, there will be a corresponding beam inside the structural floor or below or below, that is, we call the upper return beam or the lower return beam, to ensure the safety of the structure. If we look up in our homes, there are many beams.

2, we need to know where the beam exists in the room. One place is above all our walls, basically there is a beam, and this beam is to carry the load transferred by the wall. The second position is that almost all the doorways in our homes have beams above them. Like there's a beam on the pass in the hall as soon as we enter.

Third, the installation of central air conditioning can be opened in the beam

1, clean workshop design and installation according to the design specifications and the requirements of the construction quality specifications of building engineering, it is strictly prohibited to open holes on the beam in the later period. Therefore, some buildings are now reserved holes, that is, reservations are made in advance, and holes are prohibited in the later period. This is because the process of opening the hole in the later stage may destroy the steel bars inside the beam, thus affecting the stress structure of the entire house, resulting in structural insecurity.

2, many friends may think that washing a small hole on the beam has no impact, in fact, it still has an impact. For example, DN40 holes, or DN50 holes, will not destroy the overall structure of the quantity, you can think about it, many homes are so open in the beam, then the final result is that the volume of our entire building is seriously damaged.

Fourth, how to install central air conditioning without opening a hole in the beam

We need to confirm the specific decoration of our home. That is to say, whether our home is suspended ceiling or not, so as to confirm in advance. It can be convenient for us to install central air conditioning in the later period, and the treatment method is different for different situations.

1, if there is no ceiling at home. Then, when installing central air conditioning, let the pipeline of central air conditioning be installed directly along the bottom of the beam, and then lay in the corner, and the end can be covered by color.

2, the home to the ceiling. At this time, the installation of air conditioning needs to consider the installation space, you can consider the space occupied by the pipeline, it is recommended to reserve about 70mm space under the beam to take the pipeline. In this way, all the pipe Wells can be hidden in the ceiling after the ceiling, and the final decoration can be completed. It is also possible to use instruments to find out the position of the main reinforcement and stirrup, and to drill holes with a diameter below 80 at one-third of the beam length.

The above four points are a summary of common problems in the design and installation of HVAC clean room, and understand some basic knowledge to avoid stepping on pits. Thank you for watching and enjoy your life.
