Air-conditioning copper-aluminum tube wars draw on aluminum technology

Recently, the “copper-aluminum dispute” over air-conditioning connecting pipes has attracted widespread attention in the industry and consumer markets. On August 1, the symposium on alternative technology of air-conditioning connecting pipes with the theme of “advocating product technology innovation to promote healthy development of the industry” drew up the controversy.
The authoritative experts from the China Electronics Chamber of Commerce, the China Household Electrical Appliances Research Institute, the China Household Electrical Appliances Association, the China Quality Association, the China Consumers Association, the China Standards Association, and the Beijing University of Technology unanimously stated that: The air-conditioning connection tube aluminum-based copper technology is strained on copper resources. Under the general environment, a material substitution technology developed on the basis of guaranteeing the effect of the connection tube function. Experts call for: Companies should make more efforts to improve product quality and meet consumer demand. They should not be tempted to engage in casual conversations, and they should not use marketing as their purpose. They can only affect the healthy development of the air-conditioning industry.
According to Zhao Yue, a senior engineer at China Ocean University, the service life of copper-aluminum connecting pipes is more than 20 years. From January to June this year, the total volume of copper-aluminum pipes produced and sold by various manufacturers in China has reached 7 million to 8 million sets. It is expected that this year will be a breakthrough. 10 million units, some for domestic sales, and some for export to North American and European markets.
In view of the current situation in the air-conditioning industry, Zhang Xiuchun, Minister of Technology of the China Standardization Association stated that standards are not developed out of thin air and need to be based on our existing technologies, existing markets, existing consumer groups, corporate development, and technological capabilities. . At present, according to a number of companies to take the alternative method of air conditioning raw materials, the formulation of relevant standards has certain practical significance. It is hoped that relevant enterprises will jointly participate in the formulation of this relevant standard and regulate the behavior of the entire air-conditioning industry, thereby promoting the sound development of the entire industry. At the same time, the formulation of unified standards is a satisfactory answer for consumers.
It is reported that the copper-aluminum connecting pipe has been recommended by the Chinese Association of Inventions as an outstanding project for energy saving and emission reduction in 2007. From the aspect of the function of the air-conditioning connecting pipe, the copper-aluminum connecting pipe and the copper pipe have their own advantages, but the copper-aluminum connecting pipe solves the shortage of copper resources in China to some extent. At present, the technology of connecting the air-conditioner tubes to aluminum-based copper has been fully matured. The mainstream air-conditioning companies are accelerating the implementation of the "alcohol-based copper" program, gradually eliminating high-priced, inefficient copper connection pipes and supporting the country's new energy-saving policies. According to reports, China, Japan, South Korea and other countries have already increased investment in R&D in this area. The replacement of brass pipes by copper-aluminum pipes is a process in which air-conditioning companies integrate resources to acquire new technologies. With the application and popularization of new technologies and new processes, alternative areas for resources will gradually expand.
