Disclosed herein is a self-cleaning evaporation type humidification apparatus. The self-cleaning humidification apparatus is a floating drop evaporation type humidification apparatus of a new concept using a super hydrophobic surface, which provides safe humidification and does not require maintenance and repair, such as cleaning, by naturally or forcedly evaporating floating drops through control of the floating drops in the super hydrophobic surface based on the self-cleaning function, virus reproduction inhibition function, and water-repellant function of the super hydrophobic surface.

An atmosphere adjustment system includes a steam supply unit and a control unit. The steam supply unit has: a layered structure including a first lava sand layer, a mineral layer, a second lava sand layer and a lava plate, which are stacked in this order from the bottom; a heater arranged under the first lava sand layer; and a water supply pipe arranged between the first lava sand layer and the mineral layer. The control unit is able to adjust the temperature of the second lava sand layer at 60 C. or higher and 80 C. or lower by controlling at least one of the amount of water discharged through the water supply pipe or the temperature of the heater.
