A smaller one of Xrmax and (temporary Xset) is used as a compartment interior set absolute humidity Xset. An outlet air required absolute humidity Xao required to obtain Xset is calculated taking into account the humidity of exterior air introduced into the passenger compartment. Using Xao and an outlet air required temperature Tao required to obtain Tset, a control temperature Tea for controlling a compressor is determined.Type: GrantFiled: July 7, 2004Date of Patent: November 20, 2007Assignee: Keihin CorporationInventors: Mitsuru Yonekura, Shigenobu Itoh

Patent number: 7281574Abstract: A rear face inlet 25 and a foot inlet 28, and a rear face duct portion 26 and a foot duct portion 31 which are adapted to distribute air from the inlets, respectively, are disposed in alignment with each other in a transverse direction of a vehicle. As a result, a conventional overlapping portion where the rear face inlet and the foot inlet are made to overlap each other vertically somewhere along the length of each of the inlets in a transverse direction of the vehicle and a conventional overlapping portion where the rear face duct and the rear foot duct are disposed in such a manner as to overlap each other in a longitudinal direction of the vehicle somewhere along the length of a downwardly extending portion of each of the ducts can be eliminated, whereby the air conditioning unit can be constructed so as to be decreased in size vertically and longitudinally.Type: GrantFiled: February 10, 2004Date of Patent: October 16, 2007Assignee: DENSO CorporationInventors: Kazuji Shibata, Yoshio Yoshida

Patent number: 7275586Abstract: The invention relates to a heating or air-conditioning system for a motor vehicle, by which individual zones of the vehicle interior can be supplied with separately temperature-controlled air. An improved heating or air-conditioning system, which requires just a small amount of installation space, feeds differently temperature-controlled air to a plurality of air-conditioning zones. Despite the small amount of installation space, optimum mixing of cold air and warm air takes place in the heating or air-conditioning system, with the result that the air emerging from air-outlet openings in a respective air-conditioning zone have a constant temperature over the outlet cross section.Type: GrantFiled: August 29, 2005Date of Patent: October 2, 2007Assignee: Behr GmbH & Co.Inventors: Oliver Beck, Michael Förster, Christian Grömmer, Norbert Wöcht

Publication number: 20070204985Abstract: A rotary door for a vehicle air conditioner includes a rotation shaft, a door surface that is spaced from an axial line of the rotation shaft radially outside and is rotated integrally with the rotation shaft, and a seal portion provided at a peripheral end portion of the door surface. The door surface has a first door face at a center portion, and a second door face positioned at left and right sides of the first door face. The second door face has a radial dimension from the axial line, that is smaller than that of the first door face so as to form a door outer peripheral space between the seal portion of the second door face and a seal rib of an air conditioning case. Furthermore, the second door face is provided with an air guide plate extending radial outside for guiding air.Type: ApplicationFiled: February 28, 2007Publication date: September 6, 2007Applicant: DENSO CorporationInventors: Hiroshi Fukagawa, Kazuya Niimi

Patent number: 7255161Abstract: A method for controlling a heating and air conditioning system equipped with actuators, preferably vents, is provided. Interior conditions are detected by an interior sensing system, with at least the seat occupancy with occupants being automatically recognized by an object recognition system on the basis of the data supplied by the interior sensing system. An optimized adjustment of the heating and air conditioning system to the seat occupancy is automatically performed as a function of the recognized seat occupancy.Type: GrantFiled: February 24, 2004Date of Patent: August 14, 2007Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Stephan Durach, Danny Borke, Alexander Augst

Patent number: 7246657Abstract: In an air conditioner for a vehicle having first and second air conditioning zones positioned at right and left sides of a front seat in a vehicle compartment and third and fourth air conditioning zones positioned at right and left sides of a rear seat in the vehicle compartment, the air conditioner includes calculating means for calculating each of target blowing-out temperatures of air blown out to the first to fourth air conditioning zones in accordance with environmental conditions and desirable temperatures of the first to fourth air conditioning zones. In the air conditioner, the calculating means corrects an influence from the other air conditioning zones by using a selected desirable temperature in the desirable temperatures of the first to fourth air conditioning zones, while calculating the individual target blowing-out temperatures of the first to fourth air conditioning zones.Type: GrantFiled: July 12, 2004Date of Patent: July 24, 2007Assignee: DENSO CorporationInventors: Akira Oga, Katsuhiko Samukawa

Patent number: 7222665Abstract: A vehicle air conditioning system uses a non-contact temperature sensor for feedback control of the temperature of the air blown out from a blowing opening. The degrees of opening of an air mix damper and a bypass open/close damper are controlled by actuators that respond in accordance with a temperature detected by the non-contact sensor so the blowing temperature will ultimately approach a target value. Air conditioning control is achieved as desired by this feedback control of the blowing temperature without providing wiring for a temperature sensor near the blowing opening.Type: GrantFiled: October 7, 2003Date of Patent: May 29, 2007Assignee: DENSO CorporationInventors: Yoshinori Ichishi, Tatsumi Kumada

Patent number: 7191825Abstract: A vehicle air conditioning unit includes an air duct, through which air is blown into a passenger compartment, and a partition board, which partitions the air duct in its inside into a first air passage and a second air passage. Temperature of air in the first air passage and temperature of air in the second air passage can be separately controlled. The air duct has a recess on its one side. An air conditioning device is disposed in the recess. The partition board is deformed correspondingly to the recess so that a corresponding cross-sectional area of the first air passage and a corresponding cross-sectional area of the second air passage should be approximately equal.Type: GrantFiled: November 20, 2003Date of Patent: March 20, 2007Assignee: Denso CorporationInventors: Koji Yamada, Keizo Goto
