“Room Air Conditioner Defrost Performance Evaluation Method” standard released to promote the development of air conditioners towards health and comfort

[Secret Home News]Driven by rising temperatures, the air conditioner market has experienced explosive growth this year. According to data in the first half of the year, its volume has accounted for 20% of the home appliance industry. Against this background, users' requirements for the capabilities of air-conditioning products are also increasing, especially in terms of energy conservation, environmental protection, and health.

Therefore, the evaluation of air conditioning performance cannot only be limited to physical comfort, but requires clear standards for evaluation. That is, in this context, on September 4, 2023, a joint report jointly written by Xiaomi, China Electric Research Institute, CVC Weikai and others , the T/CPQS E00058-2023 “Room Air Conditioner Defrost Performance Evaluation Method” group standard was released after being reviewed and approved by the China Consumer Goods Quality and Safety Promotion Association.

Regarding this standard, representatives of various companies also expressed their opinions. Chen Weisheng, Vice Chairman of China Association for the Promotion of Consumer Goods Quality and Safety, pointed out that the current national and industry standards for air-conditioning products cannot fully meet the needs of enterprises and consumers for the development and purchase of high-quality products. need. T/CPQS E00058-2023 “Room Air Conditioner Defrost Performance Evaluation Method” standard puts forward higher requirements for the defrost performance of room air conditioners and the comfort of the defrost process, and puts forward higher requirements for promoting the quality and technology of air conditioning products. requirements, allowing companies to demonstrate their technical strength and at the same time allow consumers to quickly choose products that meet high-quality needs.

Gu Zebo, chairman of CVC Weikai, said that the standard preparation working group established by CVC Weikai and Xiaomi has determined the detection method and judgment basis for the defrost performance of room air conditioners through more than half a year of theoretical discussion and experimental verification. On this basis, CVC launched the industry's first “room air conditioner defrost comfort grade certification”, which can conduct defrost performance tests on room air conditioners with heating functions and carry out grade certification based on the test results.

Shan Lianyu, general manager of Xiaomi Group's air conditioning department, said in his speech that Mijia air conditioners have continued to explore and study the winter climate characteristics of the middle and lower reaches of the Yangtze River in China, focusing on the temperature loss duty cycle, temperature loss amplitude and heating recovery during defrost. We carried out technical research on core comfort indicators such as time consumption, and developed targeted anti-quenching and defrosting technology for air conditioners, improving consumers' experience of using air conditioners in winter. This cooperation between Xiaomi, China Electronics Technology Research Institute and CVC Weikai has become a model of inter-industry cooperation. The joint preparation and release of group standards has brought the cooperation between the two parties to a new height. At the same time, we would also like to thank Huake, Changhong, Panasonic, Skyworth, Sanhua and other universities and enterprises for their strong support. At the meeting, Vice Chairman Chen Weisheng issued the group standard participation certificate to representatives of Xiaomi and other participating units. At the same time, Chairman Gu Zebo of CVC Weikai issued the first room air conditioner defrost comfort grade evaluation certificate to Xiaomi.

The release of the group standard T/CPQS E00058-2023 “Method for Evaluation of Defrost Performance of Room Air Conditioners” gives companies a basis for product design and research and development, and testing agencies have a standard to follow. The standard-based “Room Air Conditioner Defrost Comfort Grading Evaluation” will also make product quality more visible, giving consumers a clear reference when comparing and choosing products, and further promoting the industry in the direction of health and comfort. develop.
