The present invention relates to a freezer capable of cooling a cooling object into an over-cooled state. The supercooling freezer using a downward circulation method according to an embodiment of the present invention includes: a freezing main body which is installed with a door to put the cooling object into an accommodation space or to take out the cooling object from the space; a cooling space part including an evaporator cooling air of the accommodation space by partitioning a lower part of the accommodation space; a circulation fan which circulates chilly air by being installed in the cooling space part; a supply duct which guides the chilly air generated in the evaporator to the lower part of the accommodation space from the cooling space part; a plurality of cooling plates which is extended from and linked with the supply duct in a direction where the door is located, is installed in the accommodation space at intervals in a vertical direction, and cools the air in the accommodation space by exchanging heat with the air of the accommodation space by being cooled by the chilly air from the supply duct and discharges the chilly air in the direction where the door is located; a curtain forming blower which forms an air curtain by injecting the air downward from the front of the accommodation space where the door is located when the door is opened; and a chilly air control door which controls the chilly air discharged to the cooling plate by being installed on the cooling plate located adjacently to the curtain forming blower. Therefore, the supercooling freezer according to the present invention can improve cooling efficiency by circulating the chilly air downward and at the same time as cooling the cooling object indirectly, and can cool all the cooling objects uniformly regardless of position in the accommodation space. |
