This application relates to the field of refrigeration equipment technology, and more particularly to a refrigerator. In the refrigerator of this embodiment, under the action of a first fan, cold air from the evaporator chamber enters the first refrigerator compartment through the air supply duct; a portion of the air in the first refrigerator compartment enters the return air duct through the second return air inlet, and then returns to the evaporator chamber, utilizing air convection to lower the temperature of the first refrigerator compartment. By setting an air outlet on the middle partition, another portion of the air from the first refrigerator compartment enters the second refrigerator compartment through the air outlet; the air in the second refrigerator compartment enters the return air duct through the first return air inlet, and then returns to the evaporator chamber. Utilizing the return air from the first refrigerator compartment to the second refrigerator compartment causes cold air to circulate, achieving convective cooling. Moreover, the return air duct is formed within the duct assembly inside the refrigerator compartment, eliminating the need for an additional return air duct on the outside of the refrigerator compartment, thereby reducing the thickness of the insulation layer at the rear of the refrigerator compartment. This allows for an increase in the refrigerator's volumetric efficiency without changing the overall dimensions of the refrigerator.
