Abstract
In order to improve safety in a refrigerant compressor system comprising a refrigerant compressor and an electric drive motor for driving the refrigerant compressor, and, arranged in a protected manner in an interior of a control housing, a control electronics system, comprising electric components or electronic power components, for controlling the electronic drive motor, it is proposed that, during operation of the refrigerant compressor system with combustible refrigerant, the control housing is provided with a refrigerant drain, which does not impair at least one protection criterion of the control housing, for discharging refrigerant which enters the interior due to a refrigerant leakage, said refrigerant drain causing the refrigerant entering into the interior due to the refrigerant leakage to pass out of the interior into the surroundings of the refrigerant compressor system.
