Abstract
A vent assembly of a vehicle includes a vent having a vent opening through which an airflow is directed, and a primary duct operably connected to the vent to convey the airflow toward the vent opening. A pressure relief valve is located along the primary duct. The pressure relief valve is configured to open when a pressure of the airflow in the primary duct exceeds a threshold, to divert a portion of the airflow through the pressure relief valve.
Claims20
A vent assembly of a vehicle comprising:
- a vent having a vent opening through which an airflow is directed;
- a primary duct operably connected to the vent to convey the airflow directly from a heating, ventilation and air conditioning (HVAC) unit toward the vent opening;
- and
- a pressure relief valve located along the primary duct upstream of the vent, the pressure relief valve configured to open when a pressure of the airflow in the primary duct exceeds a threshold, to divert a portion of the airflow through the pressure relief valve.
A heating, ventilation and air conditioning (HVAC) system of a vehicle comprising:
- an HVAC unit;
- a primary duct operably connected to the HVAC unit;
- a vent operably connected to the HVAC unit and configured to convey an airflow directly from the HVAC unit into an occupant compartment of the vehicle via the primary duct;
- and
- a pressure relief valve located along the primary duct upstream of the vent, the pressure relief valve configured to open when a pressure of the airflow in the primary duct exceeds a threshold, to divert a portion of the airflow through the pressure relief valve.
A vehicle comprising:
- a vehicle body defining an occupant compartment inside the vehicle;
- and
- a heating, ventilation and air conditioning (HVAC) system, including:
- an HVAC unit;
- a primary duct operably connected to the HVAC unit;
- a vent operably connected to the HVAC unit and configured to convey an airflow directly from the HVAC unit into the occupant compartment of the vehicle via the primary duct;
- and
- a pressure relief valve located along the primary duct upstream of the vent, the pressure relief valve configured to open when a pressure of the airflow in the primary duct exceeds a threshold, to divert a portion of the airflow through the pressure relief valve.
