  • Publication number: 20230266047
    Abstract: A domestic refrigerator has at least one refrigerated cabinet, to which a frost-free evaporator, which can be cooled under control, and a fan, which can be driven independently therefrom, are assigned and which is separated from a freezer compartment by a partition. A control method includes an evaporator cooling phase to cool the frost-free evaporator, which comprises phase the fan is switched off. The refrigerator has a control device, which is designed to cool the frost-free evaporator and to operate the fan. The control device is further configured to run an evaporator cooling phase for cooling the frost-free evaporator when the fan is switched off. The method is particularly advantageous for side-by-side refrigerators.

  • Publication number: 20220026128
    Abstract: A method initializes a defrosting operation in a refrigeration appliance having a speed-controlled compressor. The method includes the steps of: a) starting up the compressor at a speed set to an initial value, b) adjusting the speed of the compressor in order to prevent a temperature in a storage chamber of the refrigeration appliance from deviating from a target temperature, c) monitoring a deviation between an adjusted speed and the initial value, and d) deciding that defrosting is necessary if the deviation exceeds a limit value.

  • 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.

  • Patent number: 10066865
    Abstract: A refrigerator, in particular a household refrigerator, includes an utility chamber for cooled goods and a control device, with which a cold air flow can be introduced into the utility chamber when a cooling signal is present. A defrost heating element is rendered operative by the control device to prevent the formation of condensate and/or ice due to the cold air flow fed into the utility chamber. A timing element keeps the heating element out of operation for a predetermined time interval in response to the generation of the cooling signal.

  • Patent number: 9534826
    Abstract: A refrigeration appliance includes an evaporator and a defrost heater which periodically subjects the evaporator to a defrost process, A temperature sensor is disposed at least in proximity to the evaporator and is adapted for switching off the defrost heater once the temperature sensor detects a predetermined defrost temperature. The temperature sensor provides a predetermined defrost temperature profile having first, second and third time segments. A first defrost temperature during the first time segment changes to a second defrost temperature during the second time segment, and holds the second defrost temperature during the third time segment.

  • Publication number: 20110259896
    Abstract: A refrigeration device, in particular a refrigeration/freezer combination unit, includes a housing encompassing first and second interior spaces for accommodating items to be chilled. The first and second interior spaces are joined by an air channel for establishing an air flow from the first interior space to the second interior space. At least one intermediate wall is provided in a region of the air channel for dividing the air flow into at least two partial flows.
