The side wall of the first compartment 101 defines an air duct 104, and the first heat exchanger 102 or the second heat exchanger 103 is arranged in the air duct 104; when the first heat exchanger is arranged in the air duct (not shown in the figure), the heat quantity supplied by the first heat exchanger can be promoted to be uniformly distributed in the first chamber, and at the moment, the mode of conducting the cold quantity by the second heat exchanger can be understood as a direct cooling mode; when the second heat exchanger 103 is disposed in the air duct 104, the cold energy supplied by the second heat exchanger 103 can be promoted to be uniformly distributed in the first compartment 101, that is, the cold energy conduction mode of the first compartment 101 is an air-cooling circulation mode, at this time, the first heat exchanger 102 is directly fixed on the side wall of the first compartment 101, and the heat energy is directly diffused in the first compartment. When the cabinet body is internally provided with the air duct 104 and the second heat exchanger 103 is positioned in the air duct 104, if the first compartment 101 does not need to supply cold energy, the second heat exchanger 103 stops supplying cold energy, and at the moment, the fan 108 is started to play a role in promoting the air circulation between the first compartment 101 and the air duct 104, so that the uniform distribution of heat in the first compartment 101 is facilitated. Or, the cabinet body limits two air ducts (not shown in the figure), and the first heat exchanger and the second heat exchanger are respectively positioned in one air duct, so that the heat supplied by the first heat exchanger can be promoted to be uniformly distributed in the first chamber, and the cold supplied by the second heat exchanger can be promoted to be uniformly distributed in the first chamber. The number of the air channels in the cabinet body can be selected according to requirements.

Fig. 2 and 3 illustrate a structure in which an air duct 104 is provided in the cabinet, and the second heat exchanger 103 is located in the air duct 104. At this time, the air outlet 106 is located above the air return port 107, and the cold air flow is convenient to flow circularly by using the cold air sinking principle.

In one embodiment, as shown in fig. 2 and 3, the first heat exchanger 102 is disposed on a side wall of the first compartment 101 away from the second compartment 113, and the first heat exchanger 102 is away from the second compartment 113 to reduce heat conducted by the first heat exchanger 102 to the second compartment 113 through the side wall of the cabinet, so as to ensure the cooling effect of the second compartment 113.

Referring to fig. 2 and 3, the first heat exchanger 102 is disposed at the right side of the cabinet to be far away from the second compartment 113 at the left side of the cabinet, and the first heat exchanger 102 can also dissipate heat to the external environment at the same time. The third heat exchanger in the following embodiments may be installed in a common installation position in a refrigeration device such as a refrigerator and an ice chest, and the third heat exchanger may be disposed on a side wall of the left side of the cabinet.

It should be noted that when the second compartment 113 supplies cold energy by means of air cooling circulation, that is, the side wall of the second compartment 113 is provided with an air duct, the air duct in the second compartment 113 is independent from the air duct in the first compartment 101, that is, the air ducts of the two compartments are not communicated, so that the influence of wind cross between the two compartments on the refrigeration effect is avoided.

In one embodiment, referring to fig. 2, 3 and 7, a first temperature sensor 121 is disposed in the cabinet, the first temperature sensor 121 is used for measuring the ambient temperature in the first compartment 101, and a second temperature sensor 122 is further disposed in the cabinet, and the second temperature sensor 122 is used for measuring the temperature of the first heat exchanger 102.

In the operation process, the first temperature sensor 121 measures that the temperature in the first compartment 101 is a first temperature, the second temperature sensor 122 measures that the temperature of the first heat exchanger 102 is a second temperature, and the controller calculates the cold/heat quantity required by the first compartment based on the first temperature and the second temperature, so as to further adjust the temperature of the first compartment until the first temperature reaches a preset temperature.

Specifically, when the measured first temperature is maintained at the preset temperature, the first heat exchanger 102 and the second heat exchanger 103 keep the supply of heat or cold unchanged; when the first temperature is lower than the preset temperature, the first heat exchanger 102 increases heat supply, and/or the second heat exchanger 103 reduces or stops cold supply; when the first temperature is higher than the preset temperature, the first heat exchanger 102 reduces or stops the heat supply, and/or the second heat exchanger 103 increases the cold supply.

The first heat exchanger 102 and the second heat exchanger 103 keep the heat or cold supply unchanged, which means that the flow rates of the refrigerants in the first heat exchanger 102 and the second heat exchanger 103 and/or the rotating speed of the fan 108 in the air duct 104 are kept unchanged; the increasing/decreasing/stopping of the heat supply of the first heat exchanger 102 means that the flow rate of the refrigerant in the first heat exchanger 102 is increased/decreased/stopped; the cold quantity supply increase of the second heat exchanger 103 refers to increasing the flow rate of the refrigerant in the second heat exchanger 103 and/or increasing the rotating speed of the fan 108, the cold quantity supply decrease of the second heat exchanger 103 refers to decreasing the flow rate of the refrigerant in the second heat exchanger 103 and/or decreasing the rotating speed of the fan 108, and the cold quantity supply stop of the second heat exchanger 103 refers to stopping the flow rate of the refrigerant in the second heat exchanger 103 and/or stopping the rotation of the fan 108.

It can be understood that, in some embodiments, regarding the adjustment of the cooling capacity supply of the second heat exchanger 103, an electric damper may be further disposed at the air inlet, and the cooling capacity supplied to the first compartment 101 by the second heat exchanger 103 is adjusted by controlling the opening and closing of the electric damper and the size of the opening, which is similar to the application of the electric damper in the refrigerator and is not described herein again.
