A heating, ventilation, and air conditioning (HVAC) system configured to provide a perceived comfortable ambient environment to an occupant seated in a vehicle cabin , said system comprising: a first nozzle configured to direct a first air stream from the HVAC system ; a servo mechanism coupled to the first nozzle configured to articulate the first nozzle in order to direct the first air stream to a desired location; characterized in that the HVAC further comprises a controller in communication with the servo mechanism , said controller configured to identify a sensitive portion of a body of the occupant that is more sensitive to heat loss than other portions of the body, determine an ambient temperature of the vehicle cabin , determine a desired heat supply rate for the sensitive portion , wherein the desired heat supply rate includes a steady-state heat supply rate based on a difference between a comfortable heat loss rate for the sensitive portion and an actual heat loss rate for the sensitive portion at the ambient temperature; determine a comfortable skin temperature for the sensitive portion , determine a flow rate for the first air stream and a stream temperature for the first air stream based on at least the desired heat supply rate, the comfortable skin temperature, a discharge area of a nozzle, a dispersion angle of the nozzle, and a distance from the first nozzle to the sensitive portion , determine a location of the sensitive portion , and operate the servo mechanism to articulate the first nozzle in order to direct the first air stream to the location of the sensitive portion , said first air stream configured to have the stream temperature and the flow rate necessary to establish the desired heat supply rate for the sensitive portion . a first nozzle configured to direct a first air stream from the HVAC system ; a servo mechanism coupled to the first nozzle configured to articulate the first nozzle in order to direct the first air stream to a desired location; characterized in that the HVAC further comprises a controller in communication with the servo mechanism , said controller configured to identify a sensitive portion of a body of the occupant that is more sensitive to heat loss than other portions of the body, determine an ambient temperature of the vehicle cabin , determine a desired heat supply rate for the sensitive portion , wherein the desired heat supply rate includes a steady-state heat supply rate based on a difference between a comfortable heat loss rate for the sensitive portion and an actual heat loss rate for the sensitive portion at the ambient temperature; determine a comfortable skin temperature for the sensitive portion , determine a flow rate for the first air stream and a stream temperature for the first air stream based on at least the desired heat supply rate, the comfortable skin temperature, a discharge area of a nozzle, a dispersion angle of the nozzle, and a distance from the first nozzle to the sensitive portion , determine a location of the sensitive portion , and operate the servo mechanism to articulate the first nozzle in order to direct the first air stream to the location of the sensitive portion , said first air stream configured to have the stream temperature and the flow rate necessary to establish the desired heat supply rate for the sensitive portion . <EOS>
