  • Patent number: 12674614
    Abstract: In a cooling device having at least one storage compartment which is accessible via a door, and also having a coolant circuit and a control unit. The coolant circuit has a compressor, a force-cooled condenser with a condenser fan, and at least one evaporator. The control unit is configured so that, in a first operating mode with a closed door, the control unit operates the condenser fan at a first rotational speed, and in a second operating mode it operates the evaporator and operates the condenser fan at a second rotational speed. The second rotational speed is substantially lower than the first rotational speed and the second operating mode begins after the door has closed.

  • Patent number: 10203147
    Abstract: The invention relates to a refrigeration device, in particular a domestic refrigeration device, comprising a refrigerant circuit. The refrigerant circuit has a compressor, an evaporator, and a shut-off valve between an outlet of the compressor and an inlet of the evaporator. The refrigeration device also comprises a heater for defrosting the evaporator and a control unit that is designed to prepare for defrosting of the evaporator by operating the compressor with the shut-off valve closed.
