Definitions

  • an apparatus for supercooling comprising: a first storage space having a sub-zero temperature region; a second storage space having a temperature region different from that of the first storage space; and a container located throughout the first and second storage spaces, for storing food containing liquid or liquid.
  • the second storage space has an ardbient temperature region.
  • an apparatus for supercooling comprising: a cooling chamber for providing cool air and storing food; and a supercooling charrfcer projected outward from the cooling chamber, for inserting a container for storing food and beverages.
  • the apparatus for supercooling further comprises a cool air passage for introdxing cool air into the supercooling chamber.
  • the cool air passage may be comprised of, for example, a duct or the like.
  • the supercooling chamber is taken out of the cooling chamber in a manner that the upper part of the supercooling chamber descends at a predetern ⁇ ned angle.
  • freezing nuclei Fl are formed in the gas Lg or freezing nuclei F2 are formed on the inner wall of the container.
  • condensation occurs at a portion where the surface Ls of the liquid L and the inner wall of container C (almost matching to the cooling temperature of the cooling space S), and this condensed liquid L may be formed as freezing nuclei F3 which are ice crystals.
  • the foarring agent of a predetermined region 1510 at the freezing charrber 1110 side maintained at a temperature below 0°Chas a larger thickness than the other regions of the main body 1500.
  • the temperature of the inner surface of the main body 1500 is identical to the inside temperature of the freezing charrber 1100, and the temperature of the outer surface of the main body is identical to the arrbient temperature.
  • the rriddle portion of the main body 1500 linearly increases in temperature as it goes farther from the inner surface to the outer surface. Since the thickness of the foan ⁇ ng agent in the predetermined region 1510 is larger than that of the other regions of the main body 1500, it has a wide area having a temperature ⁇ dway between 0 0 C and the arrbient temperature.
  • the upper part of the container insertion groove 1512 may be provided with a fixing merrber (not shown), such as a holder, for fixing the container 200, and the lower part of the container insertion groove 1512 may be provided with a sealing member (not shown) for blocking the cool air of the freezing chairber 1100.
  • a fixing merrber such as a holder
  • a cool air passage 1210 for introducing cool air from the cooling cha ⁇ ber 1100 or an evaporator (not shown) is connected to the supercooling cha ⁇ ber 1200 because the supercooling charrber 1200 has to be maintained at a temperature below 0 0 C.
  • the cool air passage 1210 is provided with a valve 1220 for controlling the introduction of cool air into the supercooling chamber 1200.
  • the energy efficiency of the superocoling apparatus 1000 can be improved by blocking the introduction of cool air into the supercooling cha ⁇ ber 1200 and cooling the cooling cha ⁇ ber 1100 alone.
