  • Publication number: 20180164019
    Abstract: The invention relates to a method for controlling a refrigeration system by establishing a defrost period during an initial defrost period. One or more compressors of the refrigeration system are monitored to establish if the one or more compressors are running, and a parameter representative of the one or more compressors running is monitored. The monitoring establishes at least one parameter limit value representative of whether a defrost period or a non-defrost period is to be initiated. The invention also relates to a method for controlling a refrigeration system subsequent to an electrical power interruption. The invention also relates to control units for applying one or both of the methods according to the invention, and to a refrigeration system having one or more control units controlling the refrigeration system according to one or both of the methods.

  • Patent number: 9857112
    Abstract: The invention relates to a method for controlling a refrigerator. The method comprises the steps of establishing a time interval of a certain duration, a first use of the refrigerator starting a first time interval, starting a subsequent time interval based on the start of the first time interval, and subtracted a time difference. The subsequent time interval subtracted a time difference is being used for starting a cool-down period of the subsequent time interval. The invention also relates to a control unit for the refrigerator and to a refrigerator with such control unit.
