The following description is made with reference to specific working scenarios:

when the refrigeration apparatus 100 is in operation, when the first air return 331 is closed by the damper assembly 25, the cold air cooled by the evaporator 31 passes through the air duct 40, is sent out to the refrigeration compartment 11 by the second air inlet 41, and then returns to the evaporation chamber 30 through the second air return 42.

The flow of cool air is driven by the fan 32.

More specifically:

when the first air return opening 331 is closed by the air door assembly 25, the refrigeration device 100 is in a normal refrigeration state, the stepping motor in the fresh-keeping chamber 20 controls the air door body 252 to close the first air return opening 331, cold air in the refrigeration compartment 11 enters the fresh-keeping chamber 20 through the first air inlet 221 on the side wall 22 of the fresh-keeping chamber 20, because the first air return opening 331 is closed, a vortex is formed, air exchange between the inside of the special area and the inside of the fresh-keeping chamber is reduced while the temperature of the fresh-keeping chamber 20 is reduced, and the outward dispersion of moisture for storing articles in the fresh-keeping chamber 20 is reduced, so the humidity in the fresh-keeping chamber 20 is higher relative to the humidity in the refrigeration compartment 11, fresh vegetables and fruits can be conveniently stored, and the fresh-keeping effect is achieved.

When the first air return opening 331 is opened by the damper assembly 25, the stepping motor controls the damper body 252 to open the first air return opening 331, and the rapid cooling mode is started. At this time, after the heat exchange between the cold air in the box 10 and the stored articles is finished, the cold air with certain moisture passes through the first air inlet 221 on the side wall 22 of the fresh-keeping chamber 20, passes through the articles stored in the fresh-keeping chamber 20, and is discharged from the first air return 331, and during this process, the cooling speed in the fresh-keeping chamber 20 is faster and the temperature is lowered further; on the other hand, since the gas passing through the fresh food compartment 20 has a relatively higher humidity, the loss of water vapor in the fresh food compartment 20 is also reduced.

The air passing through the fresh food compartment 20 passes through the support 26 having the through-holes and then enters the evaporation compartment 30 through the first return air port 331. The opening degree of the air door body 252 can be adjusted by controlling the pulse instruction of the stepping motor and the rotation angle of the stepping motor, that is, the temperature and the humidity in the fresh keeping chamber 20 can be realized by controlling the opening degree of the first air return port 331, and meanwhile, the loss of moisture in the fresh keeping chamber 20 is reduced.

When the refrigeration device 100 is in the defrosting stage, the stepping motor in the fresh-keeping chamber 20 controls the air door body 252 to open the first air return opening 331, the moisture after defrosting in the evaporation chamber 30 enters the fresh-keeping chamber 20 through the first air return opening 331, the humidity in the fresh-keeping chamber 20 is improved, and after defrosting is finished, the first air return opening 331 is closed. The functions of moisture preservation, cold preservation, quick cooling, humidity improvement and the like in the fresh-keeping chamber 20 are realized by controlling the opening and closing of the first air return port 331.
