Abstract
A compressor device includes first and second compressors. The first and second compressors include first and second casings having bottom portions in which lubricant is to be stored, first and second compression mechanisms provided in the casings to compress refrigerant and discharge the compressed refrigerant into the casings, and first and second motors provided in the casings. The first and second motors each include a stator and a rotor, and drive the first and second compression mechanisms. The second compressor compresses the refrigerant discharged from the first compressor. The first and second motors have first and second passages extending from axial ends of the first and second motors and through which the refrigerant discharged from the first and second compression mechanisms passes. A cross-sectional area of the second passage is larger than a cross-sectional area of the first passage. A refrigeration apparatus includes the compressor device.
