Compressor device and refrigeration apparatus

A compressor device, comprising:

• a first compressor including
• a first casing having a bottom portion in which lubricant is to be stored,
• a first compression mechanism provided in the first casing to compress a refrigerant and discharge the compressed refrigerant into the first casing, and
• a first motor provided in the first casing, the first motor including a stator and a rotor, and the first motor being configured to drive the first compression mechanism;
• and
• a second compressor including
• a second casing having a bottom portion in which lubricant is to be stored,
• a second compression mechanism provided in the second casing to compress a refrigerant and discharge the compressed refrigerant into the second casing, and
• a second motor provided in the second casing, the second motor including a stator and a rotor, and the second motor being configured to drive the second compression mechanism,
• the second compressor being configured to compress the refrigerant discharged from the first compressor,
• the first motor having a first passage extending from one axial end to another axial end of the first motor and through which the refrigerant discharged from the first compression mechanism passes,
• the second motor having a second passage extending from one axial end to another axial end of the second motor and through which the refrigerant discharged from the second compression mechanism passes, and
• a cross-sectional area of the second passage being larger than a cross-sectional area of the first passage.
