Abstract (en)

The present invention relates to a control method for a Refrigerator-freezer unit device, Refrigerator-freezer unit device comprising a case and a refrigeration system, the case defining a freezing compartment and at least one non-freezing compartment, and at least one non-freezing branch connected in parallel to both ends of a freezing capillary tube. The control method comprises: when the refrigerator-freezer unit device is in a state of refrigeration of either of the non-refrigerated compartments, decreasing the frequency of operation of the compressor so as to cause the evaporator temperature of the refrigerated evaporator to be higher than an inter-compartmental temperature within the refrigerated compartments, and thereby increasing the humidity of the refrigerated compartments.
