Different from the installation of ordinary household air conditioning, central air conditioning project is a complex and highly professional project. There are a lot of processes from the customized design to the later construction process. What is the construction process of central air conditioning project? Here is a brief introduction to the construction process of the central air conditioning project:

1. For the mechanical equipment of central air conditioning, the construction process of central air conditioning needs to be checked and accepted before installation to see whether it conforms to relevant specifications, and make relevant records of inspection and acceptance.

2. Installation position of central air conditioning indoor unit: poor installation position of indoor unit will not only affect the actual use effect, but also cause many physical discomfort. The installation position of the central air conditioner indoor unit needs to be coordinated with the interior decoration layout, which is usually hidden in the ceiling, or it can be hidden above the high counter.

Install the water supply and return pipe, condensate pipe, signal line, etc. of the central air conditioning project, and maintain the gradient of at least 1 / 100 of the condensate pipe laid, so as not to affect the decoration effect, but also to ensure its normal discharge. During the installation of the refrigerant pipe, the cutting surface shall be filed flat, the internal and external burrs shall be removed, the sleeve joint shall be tight, and the external surface of the refrigerant pipe shall be clean during the welding. During welding, nitrogen must be injected into the copper pipe. After welding, high-pressure nitrogen shall be used for soot blowing in the pipe to keep the cleanliness of the copper pipe.

盈彩厅4. The air outlet of the external unit of the central air conditioner must be free of obstructions within 50 cm, and the shock pad shall be installed in the floor type to ensure the normal operation of the external unit. After the installation of the external unit, the refrigerant pipe shall be vacuumized to ensure the drying in the refrigerant pipe. Otherwise, the moisture contained in the air in the pipe will mix with the refrigerant to produce ice crystals, causing damage to the equipment.

5. After connecting the internal and external units of the central air conditioner, the leakage inspection shall be carried out to confirm that there is no leakage in the internal and external units and the piping system. Remember to vacuum and make sure the system is dry. If there is water in the system, it is easy to cause ice blocking and electrical insulation damage. Finally, it is necessary to test run the air conditioner to confirm whether the return air temperature, supply air temperature, operating current, voltage and other data are normal.
