A refrigerator (100) includes: a cabinet (110), in which are defined a cooling chamber (150) at a lower portion and a first storage compartment and a second storage compartment which are spaced side by side above the cooling chamber (150); and an evaporator, arranged in the cooling chamber (150) and configured to cool an airflow entering the cooling chamber (150) to form a cooled airflow. At least one first return air inlet communicated with the cooling chamber (150) is formed in a left sidewall of the first storage compartment such that a return airflow of the first storage compartment enters the cooling chamber (150) to be cooled via the first return air inlet. At least one second return air inlet communicated with the cooling chamber (150) is formed in a right sidewall of the second storage compartment such that a return airflow of the second storage compartment enters the cooling chamber (150) to be cooled via the second return air inlet. The available compartment volume of the refrigerator is increased, and the return air inlets communicated with the cooling chamber (150) are formed in left and right sidewalls of the cabinet respectively.
