1. The volumetric efficiency is high; the pressure difference between the adjacent crescent-shaped spaces is small, the leakage is small, there is no suction and exhaust valve, the resistance is small, and there is no re-expansion of the clearance volume.
2, high thermal efficiency: in the case of the same cooling capacity, about 10% higher than the reciprocating type.
3. The noise is small, the force change of the moving parts of the compressor, such as the movable scroll and the main shaft, is small, and the vibration of the whole machine is small.
4. Less parts: about 40% of reciprocating compressors.
5, light weight: the eccentric shaft that drives the moving scroll can rotate at high speed, so the volume is small, the weight is light, about l5% lighter than the reciprocating type.
6. The scroll compressor operates reliably; and it is easy to realize variable speed motion and variable displacement technology.
