Air-conditioning copper and aluminum tube technology will have standards to follow

The dispute between the copper and aluminum pipes, which had made a lot of noises, has finally subsided. The China Electronic Chamber of Commerce, China Household Electrical Appliances Association, China Quality Association, China Consumers Association and China Standardization Association unveiled their names for the air-conditioning copper-aluminum connection pipe. They believe that copper-based copper is a technological innovation of enterprises and is a feasible material. Alternative technology. The China Standards Association revealed that it will issue relevant standards as soon as possible to ensure that the technical quality of the copper-aluminum connecting pipe is up to standard.
The so-called "copper-aluminum connection pipe" refers to a pipe connecting an air-conditioning outdoor main unit and an indoor unit. The function of the pipe is mainly a refrigerant circulation path between the air-conditioning indoor unit and the outdoor unit. In the past, the connection pipe was made of pure copper. However, as the price of copper rose, some air-conditioning companies used aluminum instead of copper as the connecting pipe to reduce cost pressures.
Li Hongqi, an expert in the refrigeration industry, said that copper pipes and copper-aluminum pipes are not good or bad. As a small part of the overall components of air-conditioning, connecting pipes are basically not concerned by consumers. Due to the fact that the former air-conditioning connecting pipe was made of copper, copper and aluminum connecting pipes were used instead of copper pipes, and consumers were inevitably having doubts about whether manufacturers were “stealing work and cutting materials”. Industry sources believe that the use of copper materials to manufacture air-conditioning connecting pipes is a technical innovation in the air-conditioning industry based on the rise in copper prices, lack of copper resources, and the relative abundance of China's aluminum resources. It is reported that the air-conditioning copper-aluminum connecting pipe has also been recommended by the China Association of Inventions as an outstanding energy-saving emission reduction project this year.
The reporter learned that the mature copper-aluminum connecting pipe has a service life of more than 20 years. As early as in 2004, the air-conditioner equipped with a copper-aluminum connecting pipe was exported to the European Union, Japan and other countries. Domestic mainstream air-conditioning companies have also successfully used copper-aluminum connectors, such as Gree, Haier, Chigo, TCL, Hisense, and Kelon. Relevant data indicate that nearly 8 million copper-aluminum connecting pipes have been produced and sold by various manufacturers in the first half of this year, which is expected to exceed 10 million sets during the year.
Wu Shangjie, assistant to the president of the China Household Electrical Appliances Research Institute, said that after the copper-aluminum connection pipe has solved technical issues, companies should focus on how to promote it. The copper-aluminum tube technology has matured, but due to the lack of timely standardization and standardization, the copper-aluminum connection tube storm has been triggered.
Experts called for relevant standards to be introduced as soon as possible so that consumers can eliminate doubts and rest assured that consumption. Zhang Xiuchun, Minister of Technology of the China Standardization Association, stated that the time is currently ripe for the formulation of relevant standards. After the related companies propose to set standards, they will publish industry standards as soon as possible. "The formulation of a unified standard will give consumers a satisfactory answer."
