Abstract:
A heating, ventilation, and air conditioning (HVAC) system. An HVAC unit of the system includes a heater core, an evaporator, a plurality of mode doors that control airflow from the HVAC unit, and one or more actuators, each one of the one or more actuators moves one or more of the plurality of mode doors. A plurality of airflow sensors are each associated with a different one of a plurality of air duct outlets through which airflow from the HVAC unit flows. The plurality of airflow sensors measure airflow through each one of the plurality of air duct outlets. A control module determines airflow amount through each one of the plurality of air duct outlets based on inputs received from the sensors, and moves one or more of the plurality of mode doors until airflow amount measured by the plurality of airflow sensors is at least substantially equal to a requested airflow distribution pattern.
