PROBLEM TO BE SOLVED: To provide a working fluid storage device and a working fluid dehydration method, capable of efficiently reducing the water concentration of a working fluid stored in a storage tank.SOLUTION: A working fluid storage device 1 of the present invention comprises: a storage tank 11 storing a working fluid 12; a partition plate 13 partitioning a space volume secured in the storage tank 11 into a first space S1 and a second space S2 close to a fluid level of the working fluid 12 relatively to the first space S1; a gas introduction pipe 14 introducing dry gas into the second space S2 in the storage tank 11; and a gas discharge pipe 15 discharging the gas from the first space S1 in the storage tank 11. The partition plate 13 includes an opening 13a communicating the first space S1 with the second space S2, the dry gas absorbs water contained in the working fluid 12 to produce wet gas higher in relative humidity than the dry gas in the second space S2, and the wet gas is discharged from the first space S1 via the opening 13a of the partition plate 13. |
