<P>PROBLEM TO BE SOLVED: To provide a distilling apparatus of carbon dioxide and a washing apparatus reduced in heat fed from the outside or discharged to the outside. <P>SOLUTION: A washing system 1 is provided with an evaporation part 210 evaporating liquid state carbon dioxide; a condensing part 230 condensing carbon dioxide; a compressor 220, a valve a 271, a valve b 272, a valve c 273 and a control device 500 controlling internal pressure of the evaporation part 210 and condensing part 230; a heat path 300 for heat exchanging between the evaporation part 210 and condensing part 230; and a temperature sensor 400 detecting outer temperature. The compressor 220, valve a 271, valve b 272, valve c 273 and control device 500 control the internal pressure of the evaporator 210 to make the boiling point of carbon dioxide lower than the outer temperature detected by the temperature sensor 400, and control the internal pressure of the condensing part 230 to make the boiling point of carbon dioxide higher than the outer temperature detected by the temperature sensor 400. <P>COPYRIGHT: (C)2010,JPO&INPIT |
