Gree family has added an international leader in innovation and technological achievements

Recently, Gree family has added an international leader in innovation and technological achievements - " maglev frequency centrifugal refrigeration compressors and chillers ." The technical achievement allows the design of large centrifugal compressors and chillers level to a higher level , and significantly enhance the Chinese centrifugal chillers in the international refrigeration market competitiveness.
In the conventional refrigerant compressor , the mechanical bearing member is required , and the need for lubricating oil circulation system to ensure the mechanical work of the bearing . Gree air-conditioning and central inverter using magnetic levitation is magnetic bearings using magnetic fields to levitate the rotor , resulting in the rotation when no mechanical contact , no mechanical friction , no need for mechanical bearings and mechanical bearing lubrication system required . Using magnetic bearings , all because of the problems caused by oil and will no longer exist . Frequency magnetic levitation centrifuges in one fell swoop to overcome the traditional mechanical bearing centrifuge limited energy efficiency , noise, starting current, higher maintenance costs of a series of drawbacks , is a more energy- efficient central air-conditioning products.
