On March 8, the 2018 China Home Appliances and Consumer Electronics Expo (AWE2018) opened at the Shanghai New International Expo Center. As one of the three major home appliances and consumer electronics exhibitions in the world, AWE attracted more than 800 well-known domestic and foreign home appliances, consumer electronics and Upstream and downstream industries, cross-industry companies participated in the exhibition, including many air-conditioning compressor manufacturers.
High-efficiency, energy-saving, low-carbon and environmental protection have always been the development trend of home appliances, and also one of the important aspects of each AWE. This year's AWE, GMCC, Lingda and Haili, the three largest domestic air conditioner compressor manufacturers, collectively exhibited compressor products that use ozone-friendly, low-carbon and environmentally friendly natural working fluid HC-290 as a refrigerant.
At the AWE Apland Awards Ceremony held on March 10, GMCC's R290 green environmentally-rated fixed-speed compressor won the industry honor of "Apland Environmental Award". Yu Lifeng, deputy director of the Environmental Protection Foreign Cooperation Center of the Ministry of Environmental Protection, and Chinese household appliances The association's vice chairman Wang Lei jointly awarded the GMCC with awards.
At present, the global air-conditioning industry is accelerating the elimination of the ozone-depleting refrigerant R22 under the framework of the Montreal Protocol. R410A, R32 and other hydrofluorocarbon refrigerants selected by some companies as R22 alternative technologies have a strong greenhouse effect. It was also included in the control list by the Kigali amendment reached by the parties to the Montreal Protocol in October 2016.
As the world's largest air-conditioning manufacturing base and consumer market, China's air-conditioning industry's choice of technical route in refrigerant replacement has received great attention from the international community. After a lot of technical demonstrations and careful choices, China's air-conditioning industry has decided to use R290 as an alternative route.
Compared with R22, R410A and R32, R290 has unparalleled advantages in ozone friendliness and low-carbon environmental protection. Its ozone depletion potential (ODP) is 0, and its greenhouse effect potential (GWP) is also close to 0. Not only that, the cooling performance of R290 is excellent, especially in high temperature conditions, it has good cooling performance. The charging volume of R290 is also significantly lower than that of traditional refrigerants, and it is more efficient and energy-saving.
With the joint efforts of the Chinese government, industry associations, and industry, China ’s air-conditioning industry has achieved global attention in R290 refrigerant application research and R290 air-conditioning commercialization, and China ’s technical route claims have also received Identification and support. China's air-conditioning industry has achieved brilliant results in the application of R290 refrigerant, and compressor companies have also done a lot of work.
GMCC is the largest manufacturer of air-conditioning compressors in China. R & D of R290 compressors began as early as 2008, and the first domestic demonstration production line of R290 compressors was transformed in 2011. GMCC's R290 compressor has been mass-produced and shipped since 2013. At present, its R290 compressor has been applied in many fields including split air conditioners, mobile air conditioners and heat pump water heaters.
Highly launched the first R290 compressor production line transformation in 2013, and completed the transformation in the following year and passed the acceptance of the expert group organized by the Environmental Protection Foreign Cooperation Center of the Ministry of Environmental Protection. Up to now, Highly has shipped tens of thousands of R290 compressors.
While developing the R290 air-conditioning compressor, Highly is continuously expanding R290 to other application fields. By 2017, it has successively launched R290 compressors for heat pump water heaters and R290 compressors for dehumidifiers, making R290 such a low-carbon and environmentally friendly The refrigerant is more widely used.
Lingda is also one of the compressor manufacturers that developed R290 compressors earlier in China. At present, Lingda's R290 compressor products have been applied to many fields such as air conditioners, dehumidifiers, heat pump water heaters, and low-temperature refrigerators and freezers. Has formed a series.
During this AWE period, the three giants of household air-conditioning compressors, GMCC, Lingda and Highly, collectively exhibited their R290 compressors, making the entire AWE "green." As the second phase of the HCFC phase-out management plan for China's air-conditioning industry was officially launched in March last year, the adoption of R290 across the industry will accelerate. Whether it is an R290 compressor or an R290 air conditioner, it will appear on AWE with a larger lineup in the future.
