Abstract

The present invention discloses an apparatus for supercooling which can cool food and liquid by using a material having a large heat capacity and store the food and liquid in a supercooled state at nearly a constant temperature. There is provided an apparatus for supercooling, comprising: a storage space divided into a relatively high temperature region and a relatively low temperature region; a filling material formed of a material having a large heat capacity for filling the relatively low temperature region; and an evaporator (120) for maintaining the filling material at a low temperature by exchanging heat with the filling material. Additionally, there is provided an apparatus for supercooling, comprising: a main body (112) for storing an antifreeze solution having a temperature below the maximum freezing point of liquid in a lower part and storing air having a temperature above 0 DEG C in an upper part; and an evaporator (120) located outside the main body, for exchanging heat with the antifreeze solution.
