A climate control arrangement in which an existing automatic climate control system is adapted by an indicator quotient (TOA). A controller adjusts air duct distribution so that differential proportions of air flow can be presented to fixed air duct vents at respective height level HL, FL relative to an occupant of a motor vehicle. The indicator quotient (TAO) being determined by appropriate comparison of objective temperature, actual temperature and environmental temperature and is used by the controller for consistent occupant preferred air flow distribution between normal conditions and more extreme environmental conditions. Thus, occupant preferences for air flow distribution in normal Spring or Autumn type environmental conditions are adapted for more extreme Winter and Summer conditions without iterative and constant variation by that occupant.
A climate control arrangement for a motor vehicle, the arrangement comprising manual operation means and a controller for air distribution means and air duct means arranged to present air flows at two vent heights, the controller determining an indicator quotient (TOA) dependent upon objective temperature, environmental temperature and current temperature compared in accordance with a pre-determined relationship, the controller normally using the indicator quotient (TOA) to variously control that air distribution means to achieve a desired climate, the manual operation means being coupled to the controller to alter operation of that controller when activate to ensure a substantially fixed air flow proportion ratio is provided for a respective indicator quotient (TOA) value between the respective vent heights through the air duct means irrespective of the desired climate objective.
