Air conditioning technology is constantly developing, and the advantages of central air conditioning are getting bigger and bigger. More and more users are using home decoration to install central air conditioners. However, many users are only aware of the installation of central air conditioners. They do not know that central air conditioners have the saying "three points of equipment and seven points of installation". Using a construction team without installation qualifications will cause unqualified installation and easily leave hidden dangers. It can be seen that as a user, you should know more about the installation knowledge of central air conditioners.

Notes on installation of central air conditioning indoor unit

1, location

The installation of central air conditioning indoor unit is concealed, so it needs to be hidden in ceiling . For confirmation of the installation location of the central air-conditioning indoor unit, it is necessary to communicate and decide on the spot according to the design drawings, actual housing types and other engineering installation teams. When confirming the indoor unit of the central air conditioner, the position of the fixed position of the central air conditioner, the position of the maintenance port, the position of the air outlet and the return air outlet, and the position of the wire controller. The position of the maintenance port and the outlet cannot be blocked. The maintenance port can easily inspect and repair the electrical box, the electronic expansion valve, and the motor and other positions. The airflow in the outlet can be smooth and the return air area will not be reduced.

2. Designing

central air conditioning indoor unit should consider reasonable airflow organization, smooth drainage and convenient maintenance.

① Reasonable airflow organization refers to the choice of a reasonable return air return method according to the design needs of the central air conditioner. The most common methods include side delivery, side delivery and side delivery and down delivery. When designing, the air outlet and return air outlet can also maintain good air circulation according to the layout of the room, so that the air conditioner in the room can have better heat exchange and achieve the best use effect. In addition, the air outlet of the air conditioner cannot blow directly to people.

②Unsolution drainage means that condensate can be discharged quickly and in a timely manner, especially in the arrangement of condensate pipes for gravity drainage. The branch pipe should maintain a slope of more than 1%, and the main pipe should maintain a slope of more than 5%. The condensate pipe arrangement of the condensate lift pump should be considered. A few-shaped anti-condensate reflux design should be considered. When installing the condensate pipe, the issue of smooth air in the pipe should also be considered. Exhaust holes should be designed in a reasonable position to prevent air blockage inside the pipe.

③ Convenient maintenance means that after a central air conditioner indoor unit has sufficient repair space, which can facilitate inspection and replacement of various parts of the indoor unit, and will not cause large-scale damage to the ceiling.

3, Accessories

The accessories required for central air conditioning indoor units are mainly expansion screws and screw components. First, confirm the location of the central air conditioner indoor unit, then use a marker to mark the location where the holes need to be installed and drilled on the floor, and finally open and fix them. It should be noted that the screw should be straight and not crooked when installed. The screw should be of M8 or above size. The nuts that fix the screw should be double nuts to avoid the position of the central air conditioner indoor unit caused by slippery wires. The length of the screw also has certain standards. If the screw is too long, it should be fixed with angle steel to prevent the central air conditioner indoor unit from swinging during work.

4, dustproof

Central air conditioner indoor unit installation is usually constructed in the early stage of decoration. There will be a lot of dust and debris floating indoors in subsequent construction. Therefore, the air outlet and return air outlet of the central air conditioner indoor unit need to be covered to achieve dust and debris protection, which can protect the cleanliness of the central air conditioner indoor unit and avoid dust and debris blowing when the air conditioner is used.

5, acceptance

central air conditioning indoor unit has a strict acceptance process.First, confirm the location of the central air conditioner indoor unit, and you can compare the design drawings (after the construction drawings are confirmed, the central air conditioner construction party, the owner and the decoration construction party will sign together); second, confirm the pipeline system to check whether the construction of the air conditioner pipeline is level, especially the drainage experiment of the condensate pipe must be performed, check whether the insulation material of the pipeline system is qualified; check whether the installation spacing of the brackets of the pipeline system is qualified; finally confirm whether there is any conflict between the central air conditioner indoor unit and the decoration.

summary

Central air conditioning technology is becoming more and more mature. As people become familiar with central air conditioning, there are more and more loyal users of central air conditioning. However, many users' understanding of central air conditioners is limited to the brand, and many people ignore the importance of installation, so that various problems arise in the later use of central air conditioners. If the central air conditioner installation team you choose is unprofessional, the later maintenance will be even more miserable. Therefore, we should pay attention to the installation of central air conditioners, know more about installation knowledge, and it is easier to check problems during acceptance, so as to prevent problems before they occur.
