With the advancement of material technology and the rising pressure of copper cost, after the successful realization of steel replacement of copper in refrigerator and freezer piping systems, in recent years, the replacement of aluminum with copper in air conditioning piping systems has gradually matured. At present, the condensers of automobile air conditioners , Almost all evaporators have realized an all-aluminum structure, and the development of alloy aluminum tubes for automotive air-conditioning mainly depends on the growth of the automotive industry. While commercial air conditioners are still in the start-up stage, domestic and foreign commercial air conditioner companies have also begun to try to use aluminum parallel flow heat exchangers to replace traditional heat exchangers. With Haier, Midea and other large domestic air-conditioning companies gradually increasing their investment in commercial air-conditioning, alloy aluminum tubes for commercial air-conditioning have huge room for development.
In order to reduce costs, many air-conditioning manufacturers are trying to find new alternatives to refrigeration pipes. In the air-conditioning refrigeration pipes, the most suitable material for replacing copper pipes is alloy aluminum. The price of aluminum is less than 30% of the price of copper. There is obvious substitution of aluminum for copper. Economic value. After successfully replacing copper with steel in the piping systems of refrigerators and freezers, downstream aluminum manufacturers’ willingness to substitute materials for air-conditioning piping systems has also become very urgent. Under the premise of fully satisfying functions and energy efficiency, alloy aluminum materials are used in air-conditioning The proportion of applications in the pipeline is gradually increasing.
According to the analysis of experts in the large air-conditioning and refrigeration market, the replacement of copper pipes by steel pipes in refrigerators and freezer products is mainly due to the following reasons: First, the innovation of process methods ensures that the material properties of steel pipes can meet the requirements of refrigerators and freezer products for refrigeration pipelines. Technical requirements; second, the huge cost advantage makes home appliance manufacturers urgent to replace; third, the characteristics of steel pipes are more in line with the structural characteristics of refrigerators and freezers, which is beneficial to strengthen the strength of the internal space structure without increasing the difficulty of assembly.
My country is the largest country in the production of air conditioners, with a total annual demand of more than 80 million sets. Based on 280 yuan per set of alloy aluminum, it is estimated that the market capacity of aluminum-substitution copper will exceed 20 billion yuan. At present, the proportion of aluminum alloy in the market is still less than 7%, and the future development space is very broad. Experts in the large air-conditioning and refrigeration market believe that material substitution will be an inevitable trend in the development of refrigeration pipeline products. At present, alloy aluminum tubes for air-conditioning are still in a rapid growth period, and aluminum replacement for air-conditioning will become a new growth highlight.
