Why use copper tube for air conditioning?
Good heat conduction effect. The effect of heat conduction of gold and silver is better than copper, but used in air conditioning put fine timber to petty use.
The iron pipe is easy to corrode, and the specific heat of the copper is larger than that of the iron, and the heat absorption and the heat dissipation effect are good,
Copper tubes are mainly heat exchange and easy to maintain. But there are many manufacturers have been replaced by copper aluminum tube, but also said that the 2 is copper, aluminum is in the middle, so when buying, we should pay more attention to. Aluminum is not as durable as copper.
Because the copper tube has better anti-aging property, it is not easy to oxidize in the air. The strength and toughness are better, and the adaptability of temperature is better than other materials. Weldable.
The small density and soft texture of aluminum pipe can not compare with copper tube in mechanical performance and bending performance. In addition, the density of aluminum and copper is different, the cross-section is not the same, if the aluminum tube and copper tube connected, the connection may be welding is not strong, easy to cause refrigerant leakage, and may even explode. Aluminum and copper connection easily lead to corrosion of aluminum tubes, resulting in cooling, heating effect worse, and even cause air-conditioning can not work properly. Due to the different material, half life is almost only copper aluminum pipe, the cooling effect is relatively worse due to bending performance than copper, if consumers want to move again, bending tubes, very difficult, basically need to replace the new pipe.
