The present invention relates to a refrigerator appliance combining a fridge compartment and a freezer compartment. In order to allow an energy efficient operation, the refrigerator appliance comprises a solenoid valve (1) for controlling the flow of cooling liquid in the refrigeration circuit, the solenoid valve (1) having at least three different operating states (S1,S2,S3). Due to the plurality of different operating states, it is possible to achieve an independent operation of each of the evaporators (5a,5b) of the combi-refrigerator appliance, or a simultaneous operation of the evaporators, in accordance with the actual cooling demand in each of the compartments. Also, due to the plurality of operating states it is possible to provide one operating state in which the outlet of the compressor (2) is blocked when the compressor (2) is off, to sustain the pressure in the condensor during periods of compressor inactivity. In this way a cooling overshoot at the end of period of compressor acivity can be shifted to the beginning of each period of compressor activity, this resulting in increased energy efficiency. <IMAGE> |
