[0061] In this embodiment, the refrigerant is compressed by the compressor 111 and then enters the condenser 112 for condensation. The refrigerant condensed by the condenser 112 enters the throttling device 113 for throttling. After throttling, it enters the evaporator 103 to exchange heat with the gas in the air inlet duct 400. The refrigerant after heat exchange flows out through the outlet of the evaporator 103 and returns to the compressor 111.

[0062] Combination Figure 1 and Figure 4As shown, optionally, the compressor 111 , the condenser 112 and the throttling device 113 are all installed in the box body 101 .

[0065] Combination Figure 1 , Figure 3 and Figure 4 As shown, optionally, the housing 101 further defines an air supply space 108 adjacent to the plurality of compartments 200. The shared refrigerator 100 further includes a first partition 109. The first partition 109 is disposed in the air supply space 108 to separate the air supply space 108 into an air inlet duct 400 and a cooling duct 300.

[0070] Combination Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the air inlet duct 400 and the cooling duct 300 are adjacent to and arranged side by side.

The air outlet duct 500 is arranged through the cooling air duct 300 and the air inlet duct 400. One end of the air outlet duct 500 is connected to the air outlet 202, and the other end of the air outlet duct 500 is connected to the external space of the box body 101.

[0076] In this embodiment, the outlet duct 500 is provided through the inlet duct 400, so that the gas in the outlet duct 500 can exchange heat with the gas in the inlet duct 400. For example, the temperature of the gas in the outlet duct 500 is lower than the temperature of the gas in the inlet duct 400, and the gas in the inlet duct 400 can be initially cooled down through heat exchange, thereby increasing the cooling speed of the gas in the inlet duct 400 when exchanging heat with the evaporator 103.

[0077] Optionally, an outer wall of a portion of the air outlet duct 500 located in the cooling air duct 300 is provided with a thermal insulation layer to reduce heat exchange between the gas in the air outlet duct 500 and the gas in the cooling air duct 300 .

[0082] In this embodiment, the exhaust chamber 600 and the cooling air duct 300 are respectively located on opposite sides of the air inlet duct 400, and the exhaust chamber 600 is connected to one end of the air outlet duct 500 away from the air outlet 202, so as to increase the heat exchange area between the gas exhausted from the compartment 200 and the gas in the air inlet duct 400, thereby achieving preliminary cooling of the gas in the air inlet duct 400.

[0083] In this embodiment, the exhaust port 104 is opened in the box body 101, and the exhaust port 104 is connected to the exhaust chamber 600, so that the gas in the compartment 200 is discharged to the external space of the box body 101 through the air outlet 202, the air outlet duct 500 and the exhaust chamber 600 in sequence, and there will be no odor cross-talk with other compartments 200, thereby improving the user experience.

In this example, the inlet duct 400 includes two duct sections, which are described as the first duct section 401 and the second duct section 402. The first duct section 401 and the second duct section 402 are separated by the second partition 110. The second duct section 402 is separated from the cooling duct 300 by the first partition 109. The first partition 109 is provided with an insulation layer. After entering the first duct section 401 from the air inlet 105, the external air flows to the second duct section 402, and exchanges heat with the gas in the outlet duct 500 during the flow process to achieve preliminary cooling. After the preliminary cooling, the gas flows out of the second duct section 402 and exchanges heat with the evaporator 103, and enters the cooling duct 300 after the heat exchange to provide cold air to the compartment 200. The gas in the compartment 200 is discharged to the outside of the box body 101 through the air outlet 202 , the air outlet duct 500 and the exhaust chamber 600 in sequence.

Figure 4In the embodiment, the position of the air inlet (opened on the side wall of the box body 101) corresponds to the fan 107, and the fan 107 is used to suck the external air from the air inlet into the air inlet duct 400. In this example, the air inlet duct 400 includes two duct sections, which are described as the first duct section 401 and the second duct section 402. The first duct section 401 and the second duct section 402 are separated by the second partition 110. The second duct section 402 is separated from the cooling duct 300 by the first partition 109.

After the external air enters the first duct section 401 from the air inlet, it flows to the second duct section 402, and exchanges heat with the gas in the air outlet duct 500 during the flow process to achieve preliminary cooling. After the gas after preliminary cooling flows out of the second duct section 402, it exchanges heat with the evaporator 103, and enters the cooling duct 300 after heat exchange to provide cold air to the compartment 200. The gas in the compartment 200 is discharged to the outside of the box body 101 through the air outlet 202 , the air outlet duct 500 and the exhaust chamber 600 in sequence.
