Screw chiller-the operation process of refrigeration compressor!

Screw-type (ie twin-screw) refrigeration compressors have a pair of mutually meshing rotors with helical teeth in opposite directions. A rotor with a protruding tooth surface is called a male rotor, and a rotor with a concave tooth surface is called a female rotor. The teeth of the rotor are commensurate with the piston,

What factors affect the displacement of centrifugal compressors

1) The air filter is blocked or the resistance increases, causing the suction pressure of the compressor to decrease. When the outlet pressure is constant, the compressor pressure ratio is increased. According to the performance curve of the compressor, when the pressure ratio increases, the displacement will decrease;
