Publication number: 20090224414Abstract: In the evaporative humidifier of the present invention, a desired humidity is obtained by supplying water only to a humidifying module required for humidification. Air simply passes through a humidifying module to which water is not supplied. Accordingly, air obtained by mixing humidified air passing through the humidifying module which is wet with water being supplied thereto (wet zone) and non-humidified air passing through the humidifying module to which water is not supplied (dry zone) is blown out from an outlet of the evaporative humidifier. The mixture amount (mixture ratio) is controlled by the opening and closing of the valve, so that a desired humidity is obtained. Therefore, with the evaporative humidifier of the present invention, humidity control can be accurately performed without unnecessarily operating the humidifying device and without wasting energy.Type: ApplicationFiled: March 2, 2009Publication date: September 10, 2009Applicant: HITACHI PLANT TECHNOLOGIES, LTD.Inventors: Akira YOKOYAMA, Koji SUZUKI, Kosei KAWASAKI
