PROBLEM TO BE SOLVED: To solve a problem that, in a refrigerator using CO<SB>2</SB>as a refrigerant, the high-temperature piping of the refrigerant of a refrigerating circuit disposed near the opening edge of the refrigerator cannot be used as a dew condensation prevention pipe. SOLUTION: In this cooling storage comprising a main body composed of a heat insulating housing opened at its one face, a heat insulating door mounted at one face side, a machine room defined in the main body, a compressor mounted in the machine room and forming a part of the refrigerating circuit, and a dew condensation prevention pipe disposed at the opening edge of one face of the heat insulating housing, the refrigerant of the refrigerating circuit is CO<SB>2</SB>, the dew condensation prevention pipe is a part of a thermosiphon pipe for cooling the compressor, and a working fluid circulated as gas-liquid two phase fluid is sealed in the thermosiphon pipe.
