PURPOSE: A cooling air supply system for freezing compartment is provided to protect the surface of the grille fan from freezing by allowing a high velocity cooling air to be discharged at the surface of the freezing compartment grille fan. CONSTITUTION: A system comprises a grille fan(100) having a plurality of cooling air discharge ports(110,120,116,126) and which is mounted at the rear surface of a freezing compartment; a cooling air supply unit for supplying cooling air into a freezing compartment through cooling air discharge ports of the grille fan; and cooling air guides(122a,116a) arranged at the front surface of the cooling air discharge port and which guide the supplied cooling air to the surface of the grille fan. Thus, high temperature high humidity air is prevented from staying at the surface of the freezing compartment grille fan, to thereby prevent freezing of the grille fan surface.
