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 if it meets the relevant specifications, and relevant records of inspection and acceptance should be made.
2. The installation position of the central air conditioner indoor unit: the poor installation position of the indoor unit will not only affect the actual use effect, but also cause a lot of physical discomfort. The installation position of the central air-conditioning indoor unit needs to be coordinated with the interior decoration layout. It is usually hidden in the ceiling, or it can be hidden above the high counter.
3. Install the central air-conditioning supply and return pipes, condensate pipes, signal lines, etc. The condensate pipes laid should maintain a slope of at least 1/100, so as not to affect the decoration effect, but also ensure their normal discharge. When the refrigerant pipe is installed, the cutting surface should be filed flat, the inner and outer burrs should be removed, the socket should be tight, and the outer surface of the refrigerant pipe should be clean during welding. Nitrogen must be flushed into the copper tube during welding. After welding, high-pressure nitrogen gas should be used to blow soot in the tube to maintain the cleanliness of the copper tube.
4. The air outlet of the outdoor unit of the central air conditioner must be within 50 cm without any obstructions, and a shock pad should be installed in the floor type to ensure the normal operation of the outdoor unit. After installing the outdoor unit, vacuum the refrigerant pipe to ensure that the inside of the refrigerant pipe is dry, 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, a leak inspection should be carried out to confirm that there is no leakage in the internal and external units and the piping system. Remember to apply a vacuum to make sure the system is dry. If there is moisture in the system, it is prone to ice blockage of the system and damage to the electrical insulation. Finally, a test run is required to confirm whether the air conditioner's return air temperature, supply air temperature, operating current, voltage and other data are normal.
