Publication number: 20100126197Abstract: To provide a more comfortable vehicle cabin space for a passenger. In a vehicle humidifying/dehumidifying device 10, when a control unit 26 is switched to an “intermittent operation mode”, a pair of heat exchange elements 28A and 28B are heated simultaneously and intermittently. Additionally, this allows humidified air to be generated by both of the pair of heat exchange elements 28A and 28B when the pair of heat exchange elements 28A and 28B are being heated simultaneously by a heater 30. Consequently, in comparison to a case where the humidified air is generated alternately by the heat exchange elements 28A and 28B, the humidifying amount imparted to the humidified air when the humidified air is generated by a humidifying/dehumidifying unit 16 can be increased. Thus, it becomes possible to perform humidifying amount control corresponding to various situations in a vehicle cabin, and it becomes possible to provide a more comfortable vehicle cabin space for a passenger.Type: ApplicationFiled: April 3, 2008Publication date: May 27, 2010Inventor: Takanobu Nakaguro

Patent number: 7690582Abstract: A humidity controller apparatus (20) contains an adsorption rotor (24) and a heater (25). A first passage (21) along which a first air stream flows and a second passage (22) along which a second air stream flows are formed in the humidity controller apparatus (20). The amount of heat exchange between the first and second air streams and the amount of moisture exchange between the first and second air streams vary by adjustment to the rotating speed of the adsorption rotor (24), and the humidity controller apparatus (20) is switched between a dehumidification operation and a humidification/heating operation. During the dehumidification operation, the rotating speed of the adsorption rotor (24) is set low. The first air stream is dehumidified by the adsorption rotor (24) and then supplied to the inside of a room. The second air stream is used for regeneration of the adsorption rotor (24) and then discharged to the outside of the room.Type: GrantFiled: May 28, 2004Date of Patent: April 6, 2010Assignee: Daikin Industries, Ltd.Inventors: Nobuki Matsui, Masanobu Kawazoe, Kazuo Yonemoto
