Scroll compressors are volumetric compressors and are widely valued for their high efficiency, low noise, no residual volume, insensitivity to wet travel, and balanced operation. It works by means of two scroll disks in the upper part of the compressor. The center of the dynamic scroll is driven by the main shaft around the center of the static scroll in a circular motion, which produces compression between the two scrolls. In turn, the low-pressure gas enters the suction chamber and with the movement of the moving volute, a continuous compression process is formed. The volume of each compression chamber changes continuously through the translational rotation of the moving volute, thus compressing the gas.
Screw compressors are volumetric compressors that rely on the mutual meshing of two rotors to compress the refrigerant; centrifugal compressors are speed compressors that use the centrifugal force generated by the high-speed rotation of the impeller to compress the refrigerant.
