Air conditioning brands on the market, such as GREE, Midea, chigo... What uses copper tubes and what uses aluminium tubes?.1. Experts try to say more about the brand.2. Which is better, copper or aluminum pipe?Sincerely ask, do not copy.
At present, the domestic market, large manufacturers of air conditioners, heat exchangers are basically copper. Such as Midea, GREE, Haier. Imported Daikin, LG, Panasonic and so on.Brass is mature in technology, to meet the performance requirements is no substitute for aluminum, aluminum has a gap in corrosion resistance, hardness and so on, when very high copper prices in 2008 had proposed to replace copper with aluminum, some small manufacturers have done. But regular manufacturers do not use aluminum tube
1. Experts try to say more about the brand.It's not completely statistical. However, we can tell you that the price of nonferrous metals in raw materials has declined considerably in 2009 compared with the previous two years, which is close to the original price. As raw materials rose, manufacturers were competing to cut costs and to use cheap aluminium pipes. The defects of aluminium pipe are many, for example, easy folding section, flat die, difficult welding, short life, single use and so on. In particular, it is not accepted by the installation staff, and the users do not understand it. The contradiction is outstanding. However, aluminum tubes are available in fixed positions such as refrigerators and freezers. Air conditioning connections need to go bending, copper tube is better than the aluminum tube, manufacturers also see the pros and cons, and some manufacturers are still making up for this defect. This year the most brands of air conditioners are brass, who is not willing to die, aluminum air conditioning market basically is in the backlog.2. Which is better, copper or aluminum pipe?Obviously, the brass is good.Sincerely ask, do not copy.Keep your sincere, original copy.
I install air conditioning, contact more brands. Now the only domestic GREE, the United States can guarantee that the whole copper tube, whether it is low-end machine or high-end machine!! Other brands have used copper aluminum tubes, including Haier, are (Haier, Hisense, Kelon, CHIGO, Chunlan, AUX, and so on!) But their high-end machines are copper tubes!!! As Matsushita and mitsubishi! Daikin is a central air conditioner!! Copper is better than aluminium tube, of course copper tube! The cost should be 23 times higher! Manufacturers in order to press cost will use aluminum!! Flexible copper tube is much better, and the density is higher than the aluminum tube, fluorine (Lyons) penetration is extremely strong, if the aluminum pipe slightly spreads, will leak fluorine, and cannot fill, only has to change copper tube!! Moreover, the 20 ends of the copper aluminum tube are respectively welded with 2 joints, and the leakage of fluorine is easy in more than a few years!!!! Consider your own brand!! The price of the air conditioner is higher than that of the air conditioner!!!
