Development and performance test of small maglev centrifugal refrigerant compressor
A small maglev centrifugal refrigerant compressor is developed by integrat-ing core technologies such as magnetic bearing,high-speed permanent magnet motor,high-frequency vector frequency inverter,and high-efficiency fluid machinery,and the performance test is performed.The results show that the compressor has good perfor-mance and wide operating range,and it can achieve fast restart.Also,its self-generation function can protect magnetic bearing when power-off occurs.This refrigerant compressor can be widely used in the field of comfortable refrigeration and air-conditioning with small and medium-sized cooling capacity.
