The present invention relates to a refrigerator unit and/or freezer unit comprising a refrigerant circuit, which has a compressor, a condenser, at least one capillary tube as well as at least one evaporator, and a control device for the control of the refrigerant flow through the refrigerant circuit. The invention further relates to a method for the control of such a refrigerator unit and/or freezer unit, wherein at least one operating parameter and/or ambient parameter of the refrigerator unit and/or freezer unit is detected and the refrigerant flow is controlled by the refrigerant circuit in dependence on the detected operating parameter and/or ambient parameter. It is proposed in accordance with the invention to control the refrigerant flow in that the capillary tube is heated by means of a heating device and thereby causing the refrigerant flowing through the capillary tube to evaporate. The invention is based on the recognition that vapor produced in the capillary tube can considerably reduce and optionally completely prevent the flow of the refrigerant through the capillary tube. The greater the evaporation produced in the capillary tube, the lower the remaining refrigerant flow through the capillary tube.
