Abstract

A heat pump includes a condenser having a condenser housing; a compressor motor mounted on the condenser housing and having a rotor and a stator, the rotor having a motor shaft which has a compressor wheel for compressing working medium vapor mounted thereon, and the compressor motor having a motor wall; a motor housing which surrounds the compressor motor and has a working medium intake so as to direct liquid working medium out of the condenser to the motor wall for the purpose of cooling the motor, wherein the motor housing is further configured to form a vapor space during operation of the heat pump, and wherein the motor housing further has a vapor discharge outlet for discharging vapor from the vapor space within the motor housing.
