5 key points of central air conditioning installation
Central air-conditioning installation is a very high-end technology. I don't dare to install central air-conditioning without a few years of experience. The following Dongguan Yuefeng Electromechanical will introduce you to 5 key points that you need to pay attention to when you are in a central air-conditioning project.
1, refrigerant copper pipe:
The operating condition of the refrigerant in the central air conditioner directly determines the effect of use, so the quality of the refrigerant copper pipe is very important. The pressure in the tube of the traditional R22 refrigerant (freon) is generally about 20 kg, while the pressure in the tube of the new R410 refrigerant reaches 36 kg. Therefore, central air conditioners using new refrigerants need to choose more high-quality refrigerant copper tubes.
The copper pipe (commonly known as extruded pipe) produced by the extrusion process has uniform wall thickness and can withstand higher pressure. Another common type of copper pipe on the market is produced by drawing process (commonly known as drawing pipe), which is prone to uneven wall thickness, which poses hidden dangers to the safety of the refrigerant system.
2, copper pipe insulation:
The operation of the refrigerant directly determines the effect of use, and the copper pipe insulation cannot be ignored.
3. Condensate pipe:
The condensate pipe is hidden in the ceiling and will be closed after z*. Although the quality of the air conditioner is not good or bad, if it leaks, the consequences are serious. It must be repaired by removing part or all of the suspended ceiling or even knocking on the wall to pry the floor (brick).
4, tuyere:
Small parts are often neglected by many consumers, but this part affects the experience of use.
There are two common tuyere materials: one is ABS tuyere, the other is aluminum alloy tuyere.
There are pros and cons for each of the two outlets. The ABS air outlet is made of ABS engineering materials, which is not easy to condense. However, the material has a certain coefficient of thermal expansion and contraction, so it may squeak during use, and the air outlet may also be slightly arched in low temperatures in winter. The tuyere will turn yellow after prolonged use and it is not easy to clean.
aluminum alloy tuyere, the advantage is that it is not easy to be deformed and not easy to change color. However, because the heat transfer rate of aluminum alloy is very fast, it is easy to condense during summer use. In severe cases, water droplets will be produced.
Two types of air outlets have their own characteristics, so you can choose according to your needs.
5. Signal line:
Signal cables are not expensive, and shielded signal cables are generally used. You can rest assured in this area.
