A climate control system for a vehicle is disclosed, in which an air flow direction flap,is arranged in use to operate in accordance with a control quotient so as to present an air flow in a range of orientations. The orientations are arranged in groups which comprise base orientation levels,and at least one group of intermediate orientation levels,between two neighbouring said base orientation levels,In moving between said neighbouring base orientation levels,said air flow directing flap,passes, at least transiently, through substantially each said intermediate orientation level,whereby a variation in said presentation of said air flow A/F between said neighbouring base orientations appears to a user to be more gradual than would be a substantially stepped change if made directly therebetween.

Climate control system

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.
