| ADVANTAGES OF COPPER-ALUMINUM CONNECTION PIPE (Between indoor unit & outdoor unit) 1.1.Lower the cost greatly. The cost of copper-aluminum connection pipe is around 40% lower than copper connection pipe. 2.2.Save energy. The heat-conduct-coefficient of copper is 1.8 times of aluminum, so aluminum pipe is better to protect the heat of refrigerant. 3.3.Easier to be installed. Although the thickness of aluminum pipe is bigger (around 1.5 times) than the thickness of copper pipe, aluminum pipe is still much easier to be bended & installed. 4.4.Strong welding joint. The strength of copper-aluminum welding joint is even higher than the strength of copper & aluminum itself. 5.5.Good quality. Hisense & Haier have been using 100k & 200k sets annually for 4 years, no failure feedback. |
