This post was last edited by Yuyu in the Desert on 2022-7-24 18:43 China’s first magnetic levitation refrigeration compressor On the afternoon of July 16, the flower of smart technology in Weifang High-tech Zone bore fruit again - Tianrui Heavy Industry’s magnetic levitation refrigeration compressor was officially released and put into operation, adding new momentum to the realization of the dual-carbon goal. On the same day, Tianrui Heavy Industry released a new product - magnetic levitation refrigeration compressor, which solves the industry problems in traditional chillers. It has a higher energy efficiency ratio, achieves energy saving of more than 50%, and reduces the noise to less than 80 decibels. It is an iterative upgrade product that leads the refrigeration industry to develop in the direction of high efficiency, greenness and intelligence, and will provide important support for "carbon peak" and "carbon neutrality".
The series of energy-saving equipment such as magnetic levitation blowers and magnetic levitation vacuum pumps developed by Tianrui Heavy Industry have independent intellectual property rights and have reached the international leading level. They are widely used in high-energy-consuming industries such as cement, sewage treatment, papermaking, chemicals, and thermoelectricity. Replacing the original high-energy-consuming equipment is of great significance in accelerating the conversion of old and new kinetic energy and accelerating the realization of the "dual carbon" goal. Compared with traditional refrigeration compressors, the magnetic levitation refrigeration compressor developed by Tianrui Heavy Industry has seven major advantages.: It uses a high-frequency inverter to improve the efficiency of electric transmission. Both the stator and rotor are cooled by refrigerant, and the refrigerant flow rate, heat transfer situation, fixed part temperature field, and pressure loss of the cooling pipeline are analyzed and optimized to ensure efficient operation of the motor and achieve energy savings of more than 50%. The magnetic levitation refrigeration compressor has no gear connection, no coupling, and no contact with the bearings. It has a longer operating life, is more stable and reliable. The magnetic levitation refrigeration compressor adopts a closed motor design, which requires no lubricating oil and no hidden danger of shaft seal leakage. It is stable and reliable and can * * Reduce maintenance frequency and costs. The overall design of the magnetic levitation refrigeration compressor adapts to a wide range of working conditions, has strong adaptability to changing working conditions, stepless adjustment, and a load adjustment range of 20%-100%. There is no need to consider the issue of oil return, and the mass flow rate of circulating refrigerant in the system can be lower, effectively expanding the operating load range. Through a permanent magnet motor equipped with magnetic bearings, a gearless and oil-free system, and multiple silencing designs at the exhaust end, the noise is less than 80dB, making it quieter and more comfortable. The refrigeration compressor uses environmentally friendly refrigerant, which has high refrigeration efficiency and no damage to the ozone layer. It is more environmentally friendly and can be used for a long time.

In 2016, Hanbell Precision Machinery officially released the magnetic levitation variable frequency centrifugal refrigeration compressor and chiller. The product technical achievement appraisal meeting was also successfully held on the same day. The Secretary-General of the China Refrigeration and Air-Conditioning Industry Association and many industry experts attended the technical appraisal meeting. In 2016, Hanbell Precision reported its research work and results to the appraisal committee. In the end, Hanbell Precision's magnetic levitation variable frequency centrifugal refrigeration compressor and chiller were unanimously recognized by the experts attending the meeting. In order to let the participating experts better understand the new magnetic levitation products of Hanbell Precision Machinery, Hanbell Precision Machinery arranged an on-site visit to the new magnetic levitation products. The site not only displayed the magnetic levitation compressor, but also displayed the entire unit in operation. Hanbell Precision Machinery also demonstrated the operation of the unit to the participating experts through real-time data monitoring. After the appraisal was completed, Yu Yuxuan, chairman of Hanbell Precision Machinery, said, "Hanbell Precision Machinery has established the strongest R&D team for magnetic levitation variable frequency centrifugal compressors and chillers. Now the magnetic levitation products have been launched. In order to ensure that customers can use the most reliable products, in the next period of time, Hanbell Precision Machinery's magnetic levitation variable frequency centrifugal compressors and chillers will be put into trial operation on the market for about a year. In 2017, Hanbell Precision Machinery's magnetic levitation products will enter the mass production stage. ”
