<P>PROBLEM TO BE SOLVED: To provide a radiative cooling type quick-freeing machine for quickly cooling a radiative cooling storage before selling. <P>SOLUTION: In this radiative cooling type quick-freezing machine, a cooling coil is disposed to a lower section in the cooling storage and salt water is placed at the lower section in the storage. The inside of the radiative cooling storage and the salt water are cooled by the cooling coil. A cooled object is placed and sealed up in the radiative cooling storage. Heat is radiated from the cooled object. An atmospheric pressure in the radiative cooling storage is lowered by a vacuum pump to promote heat radiation of the cooled object. <P>COPYRIGHT: (C)2012,JPO&INPIT |
