Summary and development of scroll refrigeration compressor technology

Summary and development of scroll refrigeration compressor technology The scroll refrigeration compressor is a new type of refrigeration compressor that has only been practical for more than ten years. It is currently the most advanced compressor with a cooling capacity ranging from 4000W to 40KW. The frequently used range in China is in the field of cabinet and commercial air conditioners. Brief introduction of scroll refrigeration compressor: Scroll refrigeration compressor belongs to a volumetric compression refrigeration compressor. Compression components are composed of moving scroll and static scrollThis includes many structural features that divert the flow of gas through the compressor housing to reduce entrained oil. After entering the housing, some gas flows upward to reduce the amount of gas flowing downward toward the oil. To achieve this, the motor of the compressor may be surrounded by a sleeve having upper and lower holes for guiding the airflow to the turns of the upper and lower stator ends of the motor. In some embodiments, the suction inlet is importantly positioned relative to the two gas passages between the stator and the motor housing. The location of the inlet allows a channel to receive incoming gas and divide the flow into two opposite directions, namely upward and downward flows. The other channels only send gas upward. In addition, suction baffles, diffusers, streamlined counterweights, and / or suction tube oil catchers can also assist in gas-oil separation or minimize entrained oil
