To provide a method and a device for conditioning gas humidity capable of controlling relative humidity of a wet gas to be constant against the introduction amount per unit time of a dry gas and the fluctuation of pressure and temperature of the wet gas at a wet gas outlet part of a humidity conditioner.
In this method for conditioning gas humidity, the dry gas introduced from a dry gas inlet part 8 of the humidity conditioner 3 having the dry gas inlet part 8, the wet gas outlet part 9 and a water spraying means 7 and water atomized by the spraying means 7 are mixed within the humidity conditioner 3 to condition the gas to desired water quantity. Water quantity to be sprayed is calculated based on one or more fluctuation values selected among the introduction amount of the dry gas, pressure of the wet gas at the wet gas outlet part 9 of the humidity conditioner 3 and a value of the temperature of the wet gas at the wet gas outlet part 9 of the humidity conditioner 3. Water quantity to be sprayed is adjusted to coincide with the calculated water quantity.
