Abstract:
Provided is a vaporization-type humidification unit capable of changing only the amount of humidity without changing the air flow. A vaporization-type humidification unit comprises: a vaporization unit that evaporates moisture; a first blower that takes in humidified air humidified by the vaporization unit; a transport tube that is connected to the first blower and that transports exhaust from the first blower; a second blower that is connected to the transport tube and that discharges the humidified air discharged from the first blower to the outside; an opening that is provided in the middle of the transport tube; a humidity detection unit that is installed on the exhaust side of the second blower; and a control unit that controls the air volume discharged from the first blower and the second blower. The control unit controls the air volume discharged from the second blower to be a desired value and controls the air volume discharged from the first blower on the basis of the humidity detected by the humidity detection unit.
