PURPOSE: A refrigerator with a super freezer chamber is provided in a freezer chamber to conveniently maintain food which should be maintained at a very low temperature. CONSTITUTION: A refrigerator with super freezer chamber having a compressor for compressing refrigerant into a vapor of high temperature and high pressure for cooling a freezer chamber and a cool chamber, a condenser and a radiating fan(72) for condensing the gaseous refrigerant into a liquid state by heat exchange with ambient air and raising the temperature of the refrigerant, a first expansion valve for reducing the pressure of the refrigerant and a first evaporator, includes a super freezer chamber(F') defined with an insulation wall(61) for temperature shutting off into a predetermined size at an upper part in the freezer chamber(F) and having a door(62), a second evaporator(60) for cooling inside of the super freezer chamber into a temperature -40°C lower than the freezer chamber, and a second expansion valve(65) provided between the first evaporator and the second evaporator for expanding a refrigerant. |
