Abstract

See full text

A screw compressor includes a screw rotor having a plurality of helical grooves, a first rotor configured to mesh with the helical grooves of the screw rotor, a second rotor configured to mesh with the helical grooves of the screw rotor, and a casing having a partition wall rotatably retaining the screw rotor and covering an outer peripheral surface of the screw rotor. The partition wall includes first and second envelope portions to form first and second compression chambers. The first compression chamber compresses a fluid introduced into the casing with a suction pressure to an intermediate pressure higher than the suction pressure. The second compression chamber compresses the fluid with the intermediate pressure to a discharge pressure higher than the intermediate pressure.
