[0117] In some embodiments, an air supply channel 120 is connected between the refrigeration air duct 900 and the freezing air duct 150 , and a refrigeration air door 130 is provided in the air supply channel 120 . The refrigeration air door 130 is used to connect or block the refrigeration air duct 900 and the freezing air duct 150 .

[0118] In some embodiments, the first air outlet 600 and the second air outlet 700 are arranged at intervals in the upper and lower parts. The first air outlet 600 and the second air outlet 700 are in the shape of long strips and extend in the transverse direction, and the freezing air door 800 is also in the shape of long strips and extends in the transverse direction. The freezing air door 800 matches the shape of the first air outlet 600 so that the freezing air door 800 can completely cover the first air outlet 600.

[0119] The single-system side-by-side refrigerator has a freezer compartment 200 and a refrigerator compartment 300 which are arranged side by side in a horizontal direction, and the freezer compartment 200 and the refrigerator compartment 300 share a cooling system. An evaporator 400 and a fan 500 are usually arranged on the rear side of the freezer compartment 200. The cold energy released by the evaporator 400 is respectively transmitted from the evaporator cavity to the refrigerator compartment 300 and the freezer compartment 200 through the cooperation of the fan 500 and the corresponding air duct. The fan 500 serves as the power for the cold energy transfer process.

[0120] Usually, an air supply channel 120 and an air return channel connecting the refrigerating chamber 300 and the cooling chamber are arranged between the refrigerating chamber 300 and the cooling chamber. The air supply channel 120 is arranged on the upper side of the return channel. The cold energy emitted by the evaporator 400 is transmitted to the refrigerating chamber 300 through the air supply channel 120, and after being circulated in the refrigerating chamber 300, it is transmitted back to the evaporator 400 cavity through the return air channel, thereby forming a complete cold energy cycle, and the fan 500 serves as the power of the above-mentioned cold energy cycle.

[0121] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
