June 21, Beijing Business Daily reporters learned that the group standard of “reliability of aluminum heat exchanger for air conditioning” is about to start, will be widely associated with industry enterprises, to lead the sustainable and healthy development of the industry.
At present, there are some gaps in national standards of air refrigeration heat exchanger and heat exchanger materials, especially in reliability research. Air conditioning industry is a large consumer of electricity and copper, whether in order to strengthen the industrial chain structure, improve the safety of the industrial chain, or to contribute to the national “double carbon” goal, looking for materials other than copper is imperative.
On June 16, 2022, the fourth “Workshop on Aluminum Application in Air Conditioning Industry” organized by China Academy of Home Electrical Appliances was held online. Industry experts, air conditioning enterprises and upstream enterprises gathered together to discuss the development of aluminum application technology in the air conditioning industry, analyze technical difficulties and discuss the application direction, actively promote the research on aluminum application technology in the air conditioning industry, improve the safety of the industrial chain, and help the green and low-carbon development of the industry.
In the development of future reliability standards, weak acid salt spray or SWAAT test should be used in the investigation of corrosion resistance, and the test time should not be more than 500 hours. It should be judged by pressure resistance, ultimate pressure resistance and air tightness. In the investigation of long-term performance, the influence of corrosion and dust accumulation should be considered at least. NSS test should be used for corrosion simulation, and precipitation spray dust simulation should be used for dust accumulation. Comprehensive judgment should be made by performance decay time, performance decay rate and wind pressure drop ratio. It is reported that “reliability of aluminum heat exchanger for air conditioning” group standard work will be launched, will be widely united industry enterprises, Sino-cool standards to lead the sustainable and healthy development of the industry.
