Benefits of technology

[0012] Accordingly, an aspect of the present invention provides a refrigerator and a method of controlling the same to cool an auxiliary storage efficiently.

Problems solved by technology

However, in such case, there exists a problem that a temperature of the auxiliary storage cannot be controlled independently and the temperature of the auxiliary storage depends on a temperature of the freezer compartment or the refrigerator compartment.
Also, the cooling air in the freezer compartment or the refrigerator compartment leaks into the auxiliary storage, thereby decreasing a cooling efficiency.
