In order to be able to adjust the noise emissions of a cooling appliance (1), particularly a refrigerator, according to requirements, a control system (3) of a cooling device (3-11) has a plurality of operational modes, at least two operational modes differing in terms of their noise emissions while at the same cooling power. In a heat pump (3-11), for example, the flow resistance of a throttle valve (7) or the power level of a compressor (4) are influenced in said at least two operational modes. |
