Another 4 Cutting-edge Technologies Boost Industrial Upgrade

The 2019 "Made in China, Loved by the World" Summit was held in the headquarters of Gree in Zhuhai city. During this summit, Gree released 4 new technologies that had been recently identified as "world-leading", empowering the sustainable development of the industry with advanced energy-saving technologies. 

The 4 technologies independently developed by Gree and unanimously appraised by authoritative experts as “world-leading” are: 

1.High-efficiency dynamic pressure air bearing centrifugal compressor key technologies and applications;

2.High-efficiency magnetic resistance inverter scroll compressor; 

3.Rare earth free magnetic resistance master drive motor system for new energy vehicles; 

4.High performance straight line servo motor and driver.

“Compressors are the heart of air conditioners. Whoever owns the core technology of compressors will have a say in the industry,” said Jiang Yi, an academician at the Chinese Academy of Engineering. By focusing on the research and development of scroll compressors and air bearing compressors, Gree developed the “high-efficiency magnetic resistance inverter scroll compressor” and the “high-efficiency dynamic pressure air bearing centrifugal compressor key technologies and applications”, which has realized the comprehensive domestic production and industrialization of efficient compressors.

"From direct drive inverter centrifugal chiller with large cooling capacity to magnetic bearing centrifugal chiller, air bearing centrifugal chiller and scroll compressor, Gree has the most extended and complete product chain currently in the world air conditioning industry. Projects that require different cooling capacity all have their corresponding applicable and energy-saving products, which in the meantime has effectively improved the energy efficiency of the industry," said Jiang Yi at the meeting of appraisal.

In addition to the two compressor technologies, Gree's "rare earth free magnetic resistance master drive motor system for new energy vehicles" and "high performance straight line servo motor and driver" have achieved key technology breakthroughs in the field of motors, providing new driving forces for the development of new energy vehicles and CNC machine tools. 

Dong Mingzhu said at the appraisal meeting, “The success of the equipment manufacturing represents the influence of China's manufacturing, however the research and development of high-end equipment is still the shortcoming of the current Chinese industry. Gree will continue to increase its R&D investment in high-end equipment and help promote the great-leap-forward development of China’s manufacturing.”
