The present invention relates to a supercooling freezer capable of maintaining a supercooling state of a cooled object. The supercooling freezer using mixed air according to an embodiment of the present invention may include: a freezing main body including an accommodation space to accommodate a cooled object and a door opening or closing the accommodation space to put the cooled object in the accommodation space or to take out the cooled object from the accommodation space; a mixed chilly air generation part including a cooling passage where an evaporator cooling air in the accommodation space through heat exchange is installed, a direct passage to which the air of the accommodation space is supplied without passing through the evaporator, and a mixing circulation fan which mixes chilly air generated via the evaporator in the cooling passage with the air supplied through the direct passage and at the same time supplies the mixed chilly air to the accommodation space; a supply duct which guides the mixed chilly air generated in the mixed chilly air generation part to a lower part and an upper part of the accommodation space; and a plurality of cooling plates which is arranged in the accommodation space at intervals in a vertical direction, and cools the cooled object by heat exchange with the air of the accommodation space without spraying the chilly air to the cooled object directly by being cooled by the chilly air supplied by the supply duct. Therefore, the supercooling freezer according to the present invention can decrease power consumption, and can maintain the accommodation space in a uniformly supercooled state overall. |
