Abstract:
1. Refrigeration system comprising a refrigeration circuit, a refrigerant compressor, a condenser following on from the refrigerant compressor, an expansion device following on from the condenser and an evaporator following on from the expansion device being arranged in said circuit, said evaporator being connected to the refrigerant compressor, wherein the refrigerant compressor has a drive motor speed-controlled by an electronic motor control and a control cooling branch having refrigerant flowing through it, branching off from the refrigeration circuit between the condenser and the expansion device and being guided to a connection of the refrigerant compressor, a cooling element connected in a heat conducting manner to electronic power components of the motor control being arranged in said branch, wherein a regulating device is provided for the control cooling branch and regulates a temperature of the cooling element during operation of the refrigerant compressor such that a minimum evaporation temperature of the cooling element is above a freezing temperature and below a liquefying temperature of the refrigerant in the condenser.
