Characteristics of Hitachi scroll compressors;
1. The compressor structure of a scroll compressor with a small number of parts is composed of only five main components
2. Fixed crankshaft structure for vibration and noise, as well as a sufficiently large exhaust buffer structure, to reduce vibration and noise
3. Direct suction has low preheating and high volumetric efficiency. Direct suction does not have the destructive effect of liquid refrigerant on the lubricating oil film, which enhances the reliability and efficiency of the compressor.
4. A more reliable oil supply method, differential pressure oil supply, makes the lubrication of the moving parts of the compressor more reliable, thereby improving the reliability of the entire machine.
5. High reliability: Vortex compressors do not require the installation of suction or exhaust valve plates, resulting in more stable, efficient, and reliable operation.
6. The wide operating range can maintain high efficiency even under a large operating pressure ratio. The scroll compressor can still achieve relatively smooth operation at high rotational speeds
