    The invention relates to a method for putting into operation a domestic refrigerator (1), where, during a first period of time (25), the air cooled by an evaporator (5) of a heat pump (4) of the appliance domestic refrigerator (1) is introduced in a refrigeration compartment (2) and in a freezing compartment (3) of the domestic refrigerator (1). During a second period of time (26), the air is introduced only in the freezing compartment (3). During the first period of time (25), a compressor (6) of the heat pump (4) is initially operated at a first speed (29). Before the air is introduced only in the freezing compartment (3), the compressor (6) is operated at a second speed (31) for a predetermined time (32) within the first period of time (25). ), where the second speed (31) is greater than the first speed (29). Also, the invention refers to a domestic refrigerator appliance (1). (Machine-translation by Google Translate, not legally binding)

    finding that the efficiency of the compressor when compressing the refrigerant may be different for different speeds of the compressor. Therefore, taking into account such parameters, the value of the second speed can be set particularly well in order to reduce energy losses due to refrigerant migration as a result of the transition from the first mode of operation (FD mode) to the first period of time to the second mode of operation (FZ mode) in the second period of time.
    Preferably, during the second period of time, the compressor is put into operation at a third speed that is different from the first speed. Also, the third speed may be different with respect to the second speed. As an example, the third speed may be greater than the first speed, but less than the second speed. In such a configuration, the third highest speed of the compressor during the second period of time makes a greater cooling capacity possible, since it is circulated to the air coming from the evaporator only through the freezing compartment. However, if the third speed is less than the second speed, the power consumption of the compressor will be less than in a configuration where the third speed does not differ from the second speed.
    Preferably, the second speed at which the compressor is put into operation during the predetermined period of time is more than 10%, in particular, more than 25%, higher than the first speed. In particular, the second speed may be more than 50% higher than the first speed. Such considerable increases in compressor speed provide a particularly considerable reduction in energy loss as a result of the migration of the refrigerant caused by the transition from the operating mode during the first period of time to the operating mode during the second period of time. This is particularly true if the duration of the predetermined time span is less than 50%, in particular, less than 25%, of the total duration of the first time period.
    Preferably, during the second period of time, the air cooled by the evaporator is prevented from entering the cooling compartment by closing a first outlet of an air duct. Here, the air exits the air duct through a second outlet that leads to the freezing compartment. Such a configuration is particularly safe by preventing air from entering the cooling compartment during the second period of time.

    The indications "top", "bottom", "top", "front", "bottom", "ground", "horizontal", "vertical", "depth direction", "width direction" , "Height direction", and the like, refer to the positions and orientations of the apparatus in its intended use position with respect to an observer located in front of the apparatus and looking towards it.
    In Figure 1, a domestic refrigerator 1 is shown schematically in front view. The domestic refrigerator 1 shown in Figure 1 is a combination of a refrigerator and a freezer. Accordingly, the cooling apparatus 1 comprises a refrigeration compartment 2 and a freezing compartment 3. A first door and a second door, which are configured to close the refrigeration compartment 2 and the freezing compartment 3, respectively, are not shown. in figure 1. In figure 1, the cooling compartment 2 is shown above the freezing compartment 3. However, the cooling compartment 2 may also be below the freezing compartment 3, or the freezing compartment 3 may be arranged side by side with or inside the cooling compartment 2.
    The cooling apparatus 1 comprises a heat pump 4, of which an evaporator 5, a compressor 6, a condenser 7, and an expansion device 8 are shown in Figure 1 in a very schematic way. In a manner known as such, the heat pump 4 comprises conduits or pipes (not shown) that connect the evaporator 5 with the compressor 6, the compressor 6 with the condenser 7, the condenser 7 with the expansion device 8, and the device expansion 8 with evaporator 5. Heat pump 4 contains a refrigerant.


    A control unit 9 of the refrigerating apparatus 1 starts the compressor 6 to vary the speed of a rotating element of the compressor 6, which causes compression of the refrigerant circulating through the heat pump 4. The control unit 9 receives temperature values from a first temperature sensor 11 placed inside the refrigeration compartment 2 and a second temperature sensor 10 placed inside the freezing compartment 3. The respective locations of the control unit 9, of the compressor 6, of the condenser 7, of the expansion device 8, and of the temperature sensors 10, 11 are shown in Figure 1 only schematically. Accordingly, all these components may be arranged in appropriate places of the cooling apparatus
    1. However, a unit comprising the evaporator 5 is arranged in a space within the freezing compartment 3. The evaporator 5 is configured as a non-frost evaporator. Here, the ice that forms on the cooling fins of the evaporator 5 is defrosted from time to time, and the water that is formed in this way is evacuated from the freezing compartment 3.
    A fan 12 provides the air to be cooled by the evaporator 5 to an inlet 13 of the unit comprising the evaporator 5. Then, the air passes through the evaporator 5, whereby it is cooled. The fan 12 blows this cooled and dried air into an air duct 14 located downstream of the evaporator 5. In the air duct 14, the cooled air, which is represented by an arrow 15 in Figure 1, is divided into a first air flow 16, which is blown into the cooling compartment 2, and a second air flow 17, which is blown into the freezing compartment 3. This mode of operation, in which the fan 12 blows the air inside both compartments 2, 3 through the conduit 14, is also called FD mode, since in the FD mode a damper 18 is open. By closing the damper 18, a first outlet 19 of the air duct 14 is closed, and the air is prevented from entering the cooling compartment 2. Thus, the path to the cooling compartment 2 is closed by the damper 18, in particular in a situation where the cooling compartment 2 does not have to cool down.
    When the damper 18 is open, as shown in Figure 1, the air flows into both compartments 2, 3 in the FD mode. In this case, the air flows 16, 17 are made to recirculate to the inlet 13 of the evaporator 5 after the air has cooled the cooling compartment 2 and the freezing compartment 3. In Figure 1, return channels appear corresponding indicated by other arrows 20, 21. In FD mode, the air coming from the compartment

    cooling compartment 2. The time or moment 34 corresponds to the moment at which the measured temperature reaches a predetermined value 39. This value 39 is preferably determined experimentally. The value 39 can be a temperature reading that leads to efficiency optimization
    5 of the heat pump 4 when the compressor 6 begins to be operated at the second speed 31 at the time 34 corresponding to the value 39.
    The cooling apparatus 1 uses the two temperature sensors 10, 11 in the freezing compartment 3 and in the cooling compartment 2. However, to determine the moment 34 at which the first speed 29 is increased to the second speed 31 , only the temperature sensor temperature reading 11 disposed within the cooling compartment 2 is used. Preferably, the speed of the compressor 6 is increased as long as there is a change in the operating mode. Since the cooling apparatus 1 normally starts 15 in the FD mode, the following change occurs when the damper 18 is closed, that is, at the end of the first period of time 25 and at the beginning of the second period of time 26, in which the cooling device 1 is put into operation in the FZ mode. Here, the operation with increased compressor speed at point or moment 34 brings with it that the cooling capacity increases and that
    20 the power consumption of the refrigerator 1 decreases.
