[0002] At present, for medium and low-end side-by-side refrigerators, the refrigerating compartment mostly adopts a small air duct structure, that is, an upper air outlet and a lower air outlet are arranged in the top space, and the temperature control of the refrigerating compartment is realized by using the principle of forced convection plus natural convection and the natural sinking of cold air.

[0003] Although the existing scheme has a low cost, when it is applied to a side-by-side refrigerator with a large height, during the natural sinking process of cold air, the temperature difference between the top and the bottom is too large. When the gear temperature meets the requirements, the actual temperature in the refrigerating compartment will have a phenomenon of crossing zero.

[0004] Therefore, if it is necessary to ensure that the temperature difference between the upper and lower parts of the compartment is not too large, it is necessary to adjust the ratio of the upper air outlet and the lower air outlet to control the temperature difference between the upper and lower parts of the compartment without being able to change the size of the air damper casually.
