Even the centennial cents of Centennial Centrifuges have risen strongly

People in the HVAC industry know that centrifugal chillers (centrifuges) are the biggest players in the central air-conditioning market and also a powerful weapon for foreign brands to monopolize the Chinese market. However, since the beginning of this year, the central air-conditioning of China’s No. 1 brand has repeatedly attacked dozens of centrifuges in the first half of the year, leading the strong rise of domestic brands.

Centrifugal chiller is currently the largest central air-conditioning equipment, not only huge in size, but also high in technical content, and the manufacturing process requirements are also very exquisite. In the past century, given the limitations of technology and basic industries, there were very few companies in China that could produce centrifuges. In 2004, Midea Air-Conditioner cooperated with Chongqing General Group, which has more than 40 years experience in developing centrifuges. After many years of hard work, it developed the first domestic frequency conversion centrifuge in 2006. In 2010, it launched a domestic-made heat pump centrifuge. Domestic centrifuge technology has reached the advanced level of the industry.

The energy efficiency of centrifuges is currently the highest among central air-conditioning equipment. Because of the principle and size constraints, the single-unit cooling capacity cannot be made too small, thus affecting the performance of energy efficiency. Midea Air Conditioning has used its research results in frequency conversion technology for many years on centrifuges, launched the Ruixing High-Efficiency Centrifuge, and adopts variable frequency technology to achieve stepless regulation. Some of the energy efficiency is up to 9.1, which is more than 30% energy saving than ordinary centrifuges.

The U.S. Ruixing Centrifuge can also directly use high-voltage power supplies such as 10KV and 6KV. Users do not need to equip transformers, reducing the cost of cable purchases, significantly reducing investment costs, and reducing the power consumed by running electrical components.

Midea's centrifuges have more than ten national patent technologies, of which the patented patented compressor technology (Patent No.: ZL01256825.2) and the patented No-Link Patent Technology (Patent No.: ZL01256824.4) have reached the industry-leading level. The patented double adjustment technology with imported guide vanes and adjustable diffuser can achieve stepless adjustment of the cooling capacity within the range of 10% to 100%. This not only fully reduces the surging point of the unit operation, but also improves the operating efficiency under load, and saves the operating cost for the user. The impeller and the spindle adopt an advanced keyless connection patented technology and has a compact structure, avoiding the local stress concentration caused by the key connection and The additional imbalance of the rotor improves the life of the impeller.

After several years of market inspection, Midea's centrifuges have gradually been recognized by the industry. Since 2008, Midea's centrifuges have been used in various important buildings, such as Beijing T3 terminal supporting facilities and Shanghai Expo. In the first half of this year, Midea Centrifuge realized the blooming of the country, consecutively signed Changzhou Huadong Electromechanical City, Anhui Ou Yada Zhengyuan Furniture Plaza, Xi'an Qujiang Yintai International Shopping Center, China Gas Turbine Research Institute, and Wuhu New Hospital of Chinese Traditional Medicine. There are dozens of large-scale projects such as the Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine, Shanghai Da Zijin Plaza, Xianyang Shimao Center Hotel, and Fujian Xindong Hua Chemical Fiber Textile Base.

The rise of Midea's centrifuges shows that domestic brands already have the same competitive strength as foreign brands. As the No. 1 domestic brand, Midea Air Conditioning will lead domestic companies to internationalize.
