Can a Tiny Copper Tube Cause a Multi - Split Air Conditioner to Stop Cooling?
2025-04-06
A multi - split air conditioner has been installed at home. Now that the weather is getting hotter and hotter, but it doesn't cool. An experienced technician said that perhaps the problem lies in the tiny copper tube!
The copper tube of a multi - split central air - conditioner is an important material for the refrigeration device, connecting the indoor unit and the outdoor unit.
It has two main uses:
(1) Making heat exchangers, such as commonly used evaporators and condensers.
(2) Making connection pipes and fittings.
(1) Making heat exchangers, such as commonly used evaporators and condensers.
(2) Making connection pipes and fittings.
For a multi - split system, no matter which use it is, it is a passage for the refrigerant, and its role is of great importance. During the installation process, many improper operations on the copper tube may lead to copper tube leakage, which is a fatal defect of the air conditioner. Once there is a leak, all the refrigerant of the air conditioner will spill out, and the air conditioner will become ineffective due to the lack of a heat - transfer medium. So, what are the misunderstandings in copper tube operations?
- Irregular storage of copper tubes: Messy placement without sealing protection.
- Failure to seal the copper tube immediately after fabrication: The copper tube is not sealed in time, resulting in a lot of debris inside, which endangers the safe operation of the equipment.
- Unqualified copper tube cutting: Cutting without using professional tools, resulting in an uneven cut and many burrs.
- Inattentive connection method: The connection of copper tube diameters uses flared - mouth welding. If the welding is not firm, it will cause safety hazards such as leakage. The tube - expansion connection method must be used.
- Failure to fill nitrogen during the welding process: Welding without filling nitrogen makes the inside black and there are many oxide scales.
- Too casual pipeline layout: Messy pipe - laying, random arrangement of copper tubes. The layout should be reasonable, with pipes being horizontal and vertical.
- Improper use of tools: Bending the copper tube without using special tools, resulting in severe flattening of the copper tube and affecting the performance.
It is hoped that those in the refrigeration industry can pay more attention to the above - mentioned wrong cases during the installation project.
A multi - split central air - conditioner itself is just a "semi - finished product". It needs to go through design, installation, and construction to ensure the proper operation of the air - conditioning equipment. And every link of the installation is related to the normal operation of the entire system. If you are a property owner, it is recommended that you must find a professional team for installation.
