    摘要: A working fluid containing a component (A): a compound having a could point, as a 1 mass% aqueous solution thereof, of 20°C or higher and 50°C or lower, containing a copolymerization site between an ethylene oxide and an alkylene oxide other than an ethylene oxide, and not having an acetylene group; a component (B): a compound having a could point, as a 1 mass% aqueous solution thereof, of higher than 50°C and 80°C or lower, containing a copolymerization site between an ethylene oxide and an alkylene oxide other than an ethylene oxide, and not having an acetylene group; a component (C): at least one selected from the group consisting of an acetylene glycol having an HLB value of 4 or more and 12 or less, and an alkylene oxide adduct of an acetylene glycol having an HLB value of 4 or more and 12 or less; and a component (D): water, the working fluid containing the component (A), the component (B) and the component (C) each in a specific content.
