Patent number: 7735330Abstract: The invention relates to a heating, ventilation and air conditioning (HVAC) system, particularly a flat, modular air conditioning unit for a motor vehicle, including an essentially box-shaped casing with a length y, a height z and a width x, and several air guiding and air distribution devices placed between an air inlet and an air outlet. Air conditioning devices, including a heat exchanger and a fan, are also provided. According to the invention the air conditioning devices are linearly arranged one after another along the length y of the casing. The heat exchanger is inclined relative to the length y of the casing by an angle a? and relative to the width x of the casing by an angle b? such that y>x>z.Type: GrantFiled: February 22, 2006Date of Patent: June 15, 2010Assignee: Visteon Global Technologies, Inc.Inventors: Gerald Richter, Thomas Ehlers

Patent number: 7478670Abstract: A modular system for a 1-to-4 zone climate control system for vehicles, which is provided with at least one housing and several air tempering and air distribution devices including a fan, optionally a filter, an evaporator, a heater and several doors arranged at a partition that is placed orthogonal to the evaporator and provided to divide the total volume flow into two partial volume flows for the left and right vehicle sides. In the first configuration the partition is provided with several blind fittings for the closing of the flow paths associated with air outlets and air channels of a second configuration. In the second configuration, the blind fittings are replaced with additional doors enabling the use of the air outlets and air channels of additional zones.Type: GrantFiled: July 1, 2005Date of Patent: January 20, 2009Assignee: Visteon Global Technologies, Inc.Inventors: Gerald Richter, Thomas Ehlers

Heating and air conditioning plant for motor vehicles with a longitudinally arranged evaporator unit
Publication number: 20040226684Abstract: The invention relates to a heating and air conditioning plant for motor vehicles. The plant includes an evaporator to create cold air, a heating heat exchanger to create warm air, a mixing space to mix warm and cold air in direction of flow of the air channel system and from which the air is directed to the air conditioning zones to be differently tempered through suitable air directing devices and air outlet devices. In longitudinal direction of the vehicle, the evaporator is arranged longitudinal in the bottom region of the instrument panel center console and connected via the air directing channel system to the heating heat exchanger positioned above the evaporator and oriented almost horizontal. The air mixing chamber is configured as parallel-symmetric air guiding system with trapezoidal ducts to deviate the air flows for the left and right air outlets above the heating heat exchanger.Type: ApplicationFiled: February 19, 2004Publication date: November 18, 2004Inventors: Gerald Richter, Thomas Ehlers
