In the relentless pursuit of innovation, Gree Electric Appliances has once again set a global benchmark. On July 26th, 2024, Gree hosted a grand event themed “Advance with Determination.” During this event, Gree launched its latest strategic product, the 1300RT magnetic levitation compressor motor. The launch was significant as it coincided with the Chinese Society for Electrical Engineering certifying Gree’s “Key Technologies and Applications of Magnetic Levitation Motor Systems” as “internationally leading.” This recognition is a testament to Gree’s unwavering commitment to pushing the boundaries of technology.
Unveiling Revolutionary Products
During the event, Gree introduced several high efficiency products that are poised to redefine industry standards. These innovations include the world’s largest 1300RT magnetic levitation centrifugal compressor. Gree also introduced a wide-range integrated magnetic levitation compressor, surpassing industry cooling capacity limits. Additionally, Gree developed a magnetic levitation motor that significantly exceeds the highest IE5 efficiency standard.
Additionally, Gree unveiled a magnetic levitation air compressor that saves over 20% more energy compared to traditional screw air compressors. With 100% in-house development, manufacturing, inspection, and sales of all core components, Gree is continuously reshaping its competitive edge.
Mastery of Core Technologies
Dong Mingzhu, Chairman and President of Gree Electric Appliances, emphasized the company’s determination to control critical technologies. She stated that Gree is committed to mastering key core technologies independently. This commitment spans from single-category air conditioners to a full range of home appliances and industrial equipment. Dong highlighted Gree’s dedication to fulfilling both social and national responsibilities. The journey to mastering these technologies is neither easy nor quick. However, the ability to overcome technical challenges and achieve breakthroughs in scientific research is crucial for maintaining control over development.
Zhou Jin, Director of the Magnetic Levitation Technology and Vibration Control Professional Committee of the China Vibration Engineering Society, expressed her admiration for Gree’s achievements. She remarked, “Gree has led the development of magnetic levitation technology in the refrigeration sector, making it a pride of the industry. The relentless efforts of Gree’s magnetic levitation team over the past decade highlight their commitment to independent innovation and mastery of core technologies.”
The Strategic Importance of Magnetic Levitation Technology
Magnetic levitation technology represents a high-end bearing solution uniquely suited to extreme environments. In the military sector, U.S. companies have applied this technology to energy storage in space satellites. In the energy sector, French companies have used it for deep-sea natural gas transportation. Meanwhile, Danish companies have developed the largest 450RT magnetic levitation refrigeration compressor for industrial use.
A decade ago, magnetic levitation technology was a “no-man’s land” for Chinese enterprises, with only a handful of Western countries mastering it. The complexity of this technology stems from the intricate interplay between its components—bearings, displacement detection systems, high-speed motors, and drive systems—all of which are interconnected and involve multidisciplinary integration, making the technical barriers exceptionally high.
Understanding that key technologies cannot be acquired, bought, or begged for, Gree began its research into magnetic levitation technology in 2010. The company combined a comprehensive industrial system, complete research facilities, and a large team of highly qualified researchers to independently master the entire set of core technologies for magnetic levitation systems.
This led to the development of the world’s first 1300RT magnetic levitation compressor motor, marking the industry’s first successful commercialization of a full series of magnetic levitation compressors ranging from 50RT to 1300RT.
Gree’s Global Influence
Compared to products from European and American brands, Gree’s range of magnetic levitation refrigeration products is more comprehensive, with greater cooling capacities and broader applicability. Zhu Lei, Gree’s Marketing Director, stated, “Currently, Gree’s magnetic levitation products are widely used in office buildings, rail transit systems, data centers, and industrial refrigeration. They serve over 1,500 large-scale projects worldwide, including Asia’s largest railway hub, Beijing Fengtai Railway Station, Guangzhou South Station, and China Unicom data centers.”
Leveraging the unique advantages of magnetic levitation technology, Gree has expanded its application to magnetic levitation motors and air compressors. The magnetic levitation motor developed by Gree significantly surpasses the industry’s highest IE5 efficiency standard, while the magnetic levitation air compressor saves more than 20% energy compared to traditional screw compressors.
Commitment to Industry Standards and Future Innovations
Gree’s dedication to technological innovation extends beyond product development. The company is also actively involved in establishing industry standards for magnetic levitation technology. In collaboration with the Energy Conservation and Resource Utilization Center of the Machinery Industry and the Shanghai Electrical Apparatus Research Institute, Gree has co-authored the industry standards for magnetic levitation technology. This effort is aimed at promoting the upgrade of energy-efficient equipment such as magnetic levitation water cooled centrifugal chillers and motors, thereby enhancing China’s global influence in the magnetic levitation industry.
Core technologies are the cornerstone of a nation’s economic development and security. They play a crucial role in driving high-quality economic growth and ensuring national security. Innovation is an ongoing journey, and it is through continuous innovation that the future is shaped. With a strong sense of responsibility and urgency, Gree Electric Appliances is committed to overcoming challenges, striving for excellence, and seizing the high ground in the competition for technological advancement and future development.
Conclusion
Gree’s advancements in magnetic levitation technology not only position the company as a global leader but also reflect its broader mission to contribute to the technological progress and sustainable development of society. As Gree continues to innovate and set new standards, it reinforces its role as a pioneer in the industry, shaping the future of technology and leading the charge in sustainable industrial solutions.
