Abstract

A refrigerator is provided, including a refrigerator body having first and second cooling chambers formed therein, partitioned by a barrier wall, an evaporator provided within the barrier wall, a first cooling fan disposed at one side of the evaporator to blow cooling air into the first cooling chamber, and a second cooling fan provided at the other side of the evaporator to blow cooling air to the second cooling chamber. First and second suction openings are formed at upper and lower surfaces of the barrier wall, respectively, such that air drawn into the barrier wall through the first and second suction openings are brought into contact with different regions of the evaporator and is not mixed, so that the first and second cooling chambers may be separately or simultaneously cooled to appropriate temperatures.
