Copper and aluminum tube advantages

One is energy saving. The piping used in the heat exchangers of the indoor unit and the outdoor unit of the air conditioner requires high heat transfer efficiency and can quickly transfer the cooling amount to the room, and the connecting pipe between the indoor unit and the outdoor unit is just the opposite, requiring the tube The heat transfer efficiency of the road is low, and the lower the heat transfer efficiency, the more energy-efficient. Whether copper tubes or aluminum tubes are used, an insulating sleeve is sheathed in the metal tube to reduce the loss of the cooling capacity of the connecting tube. The thermal conductivity coefficient of copper is 1.8 times that of aluminum. Therefore, the use of a copper-aluminum connection pipe will facilitate the insulation of the connection pipe, reduce the waste of cooling capacity, and increase the energy saving level.
The second is simple welding process and reliable quality. The welding process and quality are the key to the copper-aluminum connection tube technology. Currently, the copper-aluminum connection pipes used by mainstream air conditioner manufacturers are all third-generation copper-aluminum connection tubes. It adopts the world's most advanced resistance welding technology, and the welding process is simple and reliable. The strength of the weld seam is higher than that of copper tubes and aluminum tubes.
The third is corrosion resistance and long life. The currently used copper-aluminum connecting pipes are protected by cross-linked polyethylene (heat-shrinkable tubes) to ensure that the moisture and dampened air can corrode the aluminum tubes, and at the same time improve the insulation effect of the aluminum tubes. The life of this material can be Reached 20 years.
