Features
■  Magnetic bearing design, the magnetic bearing has no contact with the shaft, and there is no mechanical friction during the operation of the unit, which greatly reduces the mechanical loss of the compressor and greatly improves the energy efficiency of the unit. The comprehensive energy efficiency IPLV is as high as 6.039.
■ The unit adopts rare earth permanent magnet DC variable frequency motor, the permanent magnet has no excitation loss, the motor efficiency is higher, the partial load is 25-40% higher than the ordinary asynchronous motor, and the full load is 3-5% higher.
■The whole system runs without oil, avoiding the formation of thermal resistance on the heat exchange surface after lubricating oil enters the heat exchanger, and the heat exchange efficiency is higher.
■High-efficiency flooded evaporator, the heat exchange efficiency is increased by more than 30% compared with the traditional dry evaporator, which greatly improves the energy efficiency of the unit.
■Starting current as low as 2A, no current impact, no mechanical impact, to ensure the safety of the power grid; variable frequency operation, the compressor can be adjusted steplessly according to the user's load demand, and output on demand.
■ Maintenance free of lubricating oil system, which can eliminate almost all daily inspection and maintenance items, which is more convenient and worry-free.
■ Super low noise operation: When the magnetic levitation compressor is running, the shaft is suspended due to magnetic force, without contact with the bearing, and the design without lubricating oil greatly reduces the operating noise.
■ For applications with cooling and hot water, the unit provides heat recovery options. By recovering waste heat from condensation, free hot water is produced, reducing waste heat emissions, saving energy and protecting the environment.
