Publication number: 20110114739Abstract: When there is no occupant in seats other than a driver seat during a foot mode, an air-conditioning controller executes a single seat concentration mode to prevent blowing of warm air to a passenger seat and a backseat by closing foot outlets on a passenger seat side and a backseat side. In this case, in order to maintain an air volume blown from the foot outlet on a driver seat side when the controller changes the mode from the normal foot mode to the single seat concentration mode, the controller sets a blower level to be lower than in the case of the normal foot mode with respect to the same target blown air temperature. Thus, an electric power consumed by an electric motor of a blower can be reduced, thereby realizing energy saving.Type: ApplicationFiled: November 15, 2010Publication date: May 19, 2011Applicant: DENSO CORPORATIONInventors: Haruki Misumi, Takuya Kataoka, Koji Ota, Michio Nishikawa, Shinichirou Hirai, Yoshiaki Suzuki, Akihiro Haraguchi, Katsuji Kuwada, Yasuhiro Sagou
