Abstract

Die Kühlvorrichtung betrifft einen Kühlschrank oder eine Kühltruhe und weist einen Kompressor (5) mit einem elektrischen Antriebsmotor auf. Der Antriebsmotor ist von einem elektronischen Drehzahlsteller (16) angesteuert. Der Kompressor (5) beaufschlagt einen Kühlmittelkreislauf, der einen Kondensator (7), einen Verdampfer (6) und eine dazwischen angeordnete Expansionseinrichtung beinhaltet. Die Kühlvorrichtung weist ein durch eine Tür (3) abschließbaren Kühlraum (1) auf sowie eine Temperaturregelung (17) für den Kühlraum. Der Drehzahlsteller (16) und die Temperaturregelung (17) sind zu einer baulichen Einheit (8h) zusammengefasst.

Figure 00000001
The cooling device relates to a refrigerator or a freezer and has a compressor (5) with an electric drive motor. The drive motor is controlled by an electronic speed controller (16). The compressor (5) acts on a coolant circuit which contains a condenser (7), an evaporator (6) and an expansion device arranged between them. The cooling device has a cooling space (1) which can be locked by a door (3) and a temperature control (17) for the cooling space. The speed controller (16) and the temperature control (17) are combined to form a structural unit (8h).
