PURPOSE: A device for circulating cold air is provided to distribute uniform temperature in the refrigerating chamber and meet the work load effectively. CONSTITUTION: A device comprises: a first, a second, and a third horizontal ducts(21,22,23) to provide cold air to the upper, middle, and lower shelves of the refrigerating chamber(2) respectively; a first cold air passage(31) to supply the cold air produced in the evaporator(3) to the first and the second horizontal ducts; a second cold air passage(33) to supply the cold air produced in the evaporator to the third horizontal duct; a first fan(41) to blow the cold air produced in the evaporator to the 1st cold air passage; and a second fan(43) to blow the cold air produced in the evaporator to the second cold air passage. Herein, the second fan is installed in the upper part of the evaporator with a certain interval. Therefore, the device maintains the temperature distribution in the refrigerating chamber uniformly while preventing load to the refrigerating chamber. |
