A refrigeration device with a refrigerant circuit for cooling at least two cooling chambers. The device has a condenser of the refrigerant circuit configured to liquidize refrigerant, a compressor of the refrigerant circuit compresses refrigerant, a first evaporator of the refrigerant circuit cools a first cooling chamber of the refrigeration device, a second evaporator of the refrigerant circuit cools a second cooling chamber of the refrigeration device, and a multi suction line of the refrigerant circuit connects the condenser with the compressor. The first and second evaporators are positioned on the multi suction line in a consecutive order. The multi suction line has a first capillary tube, a second capillary tube, and a suction pipe. The first capillary tube connects the condenser with the first evaporator, the second capillary tube connects the condenser with the second evaporator, and the suction pipe connects the first and second evaporator with the compressor.
