Patent number: 6698512Abstract: An improved vehicle heating and air conditioning system includes a driver-manipulated temperature selector that is physically coupled to a discharge temperature control mechanism. The selector is operable in a normal mode in which movement of the selector away from a full cold setting produces a corresponding movement of the temperature control mechanism that increases the discharge air temperature by re-heating or a high fuel efficiency mode in which movement of the temperature selector away from the full cold setting allows the temperature control mechanism to remain in a full cold position for a limited range of selector movement while the discharge air temperature is increased by capacity reduction of the refrigerant compressor. The temperature selector is in the form of a rotary knob that is axially shiftable to change modes when the selector is positioned at the full cold setting and spring-biased so that the normal mode is established as the default mode.Type: GrantFiled: January 7, 2002Date of Patent: March 2, 2004Assignee: Delphi Technology, Inc.Inventors: Wayne Oliver Forrest, Phillip M.

Patent number: 5775415Abstract: An air conditioning system for an automobile having an evaporator, in a refrigerating circuit, and a heater core which is located downstream from the evaporator in a duct having an inlet for introduction of air and an outlet for discharging the air into a cabin, and an air mix damper for controlling the ratio of the amount of air into the heater core and the amount of air by-passing the heater core. The degree of the opening of the air mix damper is controlled in accordance with the cooling capacity at the evaporator sensed by an after-evaporator temperature sensor so that a target value of the temperature of the air discharged into the cabin is obtained. A correction of the degree of opening of the air mix damper is done by estimating an actual temperature at the after-evaporator sensor during a transient state of the system between the ON and OFF conditions of a compressor, so that a desired setting of the air conditioning state is maintained.Type: GrantFiled: July 7, 1994Date of Patent: July 7, 1998Assignee: Nippondenso Co., Ltd.Inventors: Tomohisa Yoshimi, Takayoshi Kawai, Yuji Ito, Masafumi Kawashima, Yuji Honda, Katsuhiko Samukawa
