| Second, the central air-conditioning installation process |
The central air-conditioning installation must be ready before the renovation. Generally, after the water electrician enters the site, the construction and installation can be arranged. The home central air-conditioning can generally be divided into three installations.
The first installation: lifting the machine, installing the pipe
The first installation is to contact the installation when the hydropower enters the market, including lifting the central air-conditioning indoor unit, and wrapping the internal machine to prevent dust and impurities from entering. Pay attention to two problems when lifting the internal machine. Firstly, the internal machine is installed away from the roof. The distance must not be less than 1 cm to avoid resonance with the roof when the machine is running. Second, the internal machine must be hoisted in a horizontal position. After installation, special tools are used to measure the level.
After the internal machine is installed, you can install the pipe. This is the most important part of the central air-conditioning installation process. During installation, pay attention to the following points: First, all the welding points of all welding points should be welded at the junction of the copper pipe and the branch pipe; second, nitrogen must be flushed into the copper pipe during the welding process; After the tube should be blown with high-pressure nitrogen, keep the copper tube clean; Fourth, the copper tube must be pressure test, the general pressure test time is 24 hours.
Second installation: lifting outdoor unit, nitrogen filling pressure
The second installation is generally performed 24 hours after the first installation. Including the installation of central air-conditioning outdoor unit, the fan outlet of the external unit must be within 15cm from the back of the 50cm inside and outside the machine. There must be a damper block on all the landing feet to ensure that the external unit operates normally. Then it was filled with nitrogen and pressure was maintained. The central air-conditioning system was tested to measure the size and position of the tuyere.
The third installation: installation of air outlet, equipment operation test
The third installation can be performed after the second installation or the next day. Usually, the return air inlet is installed together with the access port. The size of the air outlet must be in line with the return air outlet of the internal machine, and no misalignment can occur. Only in this way can the best return be achieved. Air volume, and ensure there is enough maintenance space. After the tuyere installation is complete, the device is finally tested for operation. At this point, the central air-conditioning installation is basically completed.
| Third, the central air conditioning installation precautions |
1, determine the indoor and outdoor machine installation location
Indoor unit installation location: Poor installation of the indoor unit will not only affect the actual use results, but will also cause a lot of physical discomfort.

Look at the next few points of acceptance.
1, check the installation location is appropriate
The location of the central air-conditioning system is very sophisticated, and it is not where the user prefers to install it. Otherwise, maintenance costs and poor cooling results will be incurred. After the installation is complete, check whether the indoor unit's fuselage is 1.8 to 2.2 meters away from the ground. There are no obstacles within 60 cm of the outlet of the unit. The installation of the outdoor unit avoids soot, sand, direct sunlight, and poor heat dissipation. Where there is a high-temperature heat source, does the device support have an operating space for safe installation and maintenance?
2, check the central air conditioning material is qualified
All materials should have a certain anti-corrosion effect, the exhaust pipe must use non-combustible materials or non-flammable materials; air-conditioning accessories must not use harmful materials.
3, the central air conditioning noise meets the requirements
Air conditioning operation will produce a certain amount of noise, but if the noise is excessive, it may be due to improper installation. During the acceptance, it should be noted that the central air-conditioning noise must be less than or equal to 48 decibels.
4, sealing acceptance
There should be no leakage of refrigerant and brine in all parts of the air-conditioning system.
5, pipeline acceptance
The direction of copper pipes, water pipes, signal lines and power lines used in central air-conditioning shall be as horizontal and vertical as possible for aesthetic purposes.
