There are many specifications of air conditioning copper tubes, commonly including 850mm * 290mm * 185mm, 850mm * 265mm * 210mm, 850mm * 290mm * 185mm, etc. Different specifications of copper tubes are suitable for different types of air conditioners. Generally, the larger the specification of the copper tube, the better the cooling/heating effect of the air conditioner. When choosing air conditioning copper tubes, factors such as the diameter, wall thickness, and material of the copper tube need to be considered. At the same time, it is also necessary to pay attention to the performance indicators such as the corrosion resistance, thermal conductivity, and compressive capacity of the copper tube to ensure the quality and service life of the copper tube.
