Abstract (en)

[origin: WO2018065071A1] The invention relates to a semi-hermetic coolant compressor, comprising a reciprocating compressor, an electric motor, a complete housing which has a motor housing section for the electric motor and a compressor housing section for the reciprocating compressor, a suction-side coolant path which leads from a suction connection on the complete housing to an inlet chamber of the reciprocating compressor, and a pressure-side coolant path which leads from an outlet chamber of the reciprocating compressor to a pressure connection on the complete housing. The aim of the invention is to improve such a coolant compressor such that the coolant compressor functions more efficiently. This is achieved in that the electric motor is designed as a synchronous motor, the rotor of which is equipped with permanent magnets for the synchronous operation of the electric motor and a squirrel cage for starting up the electric motor in the asynchronous operation.
