Abstract
A blower case for a heating, ventilation, and air conditioning (HVAC) system. The blower case includes an inlet for airflow entering the blower case. Also included is a dehumidifier, which is movable between a first position and a second position. In the first position the dehumidifier is in a path of airflow entering the blower case through the inlet. In the second position the dehumidifier is not in the path of airflow entering the blower case through the inlet.
Claims20
A blower assembly for a heating, ventilation, and air conditioning (HVAC) system, the blower assembly comprising:
- a blower case defining an inlet for airflow entering the blower case and an outlet for airflow exiting the blower case;
- a blower within the blower case between the inlet and the outlet;
- and
- a dehumidifier movable between a first position in which the dehumidifier is within the blower case between the inlet and the blower in a path of airflow entering the blower case through the inlet, and a second position in which the dehumidifier is outside of the blower case and not in the path of airflow entering the blower case through the inlet.
A blower assembly for a heating, ventilation, and air conditioning (HVAC) system of a vehicle, the blower assembly comprising:
- a blower case defining an inlet for recirculated airflow entering the blower case from a passenger cabin of the vehicle and an outlet for airflow exiting the blower case;
- a blower within the blower case between the inlet and the outlet for drawing airflow into the blower case from the passenger cabin, and for recirculating airflow back to the passenger cabin through an outlet of the blower case;
- an actuator;
- and
- a dehumidifier movable by the actuator between a first position in which the dehumidifier is within the blower case between the inlet and the blower in a path of airflow entering the blower case through the inlet from the passenger cabin during a warm-up mode of the HVAC system for warming the passenger cabin of the vehicle at engine start, and a second position in which the dehumidifier is outside of the blower case and not in the path of airflow entering the blower case through the inlet when the HVAC system is not in the warm-up mode.
