Beschreibung
Zusammenfassung:	A screw compressor includes a casing forming an outer shell, a screw shaft configured to be driven to rotate, a screw rotor fixed to the screw shaft, a gate rotor forming, together with the casing and the screw rotor, a compression chamber in which to compress refrigerant, a slide valve configured to slide in a direction parallel to an axis of rotation of the screw rotor, a bearing housing having a bearing inside, the bearing being configured to support one end of the screw shaft so that the screw shaft is able to rotate, an oil separator configured to separate oil mixed into refrigerant compressed in the compression chamber, and a heating mechanism connected to the oil separator and configured to, by utilizing oil separated by the oil separator, thermally expand the bearing housing in a radial direction during operation.
