A supplemental air distribution system for a motor vehicle includes comprising one or more supplemental ducts for directing ambient air from an exterior of the motor vehicle to a passenger cabin interior. The one or more supplemental ducts each include an actuable door for allowing and preventing airflow. Cooling air is supplied from the one or more supplemental ducts to the passenger cabin interior via dash panel ducts and one or more register outlets. Advantageously, the one or more supplemental ducts bypass at least the vehicle heating, ventilation, and air-conditioning (HVAC) evaporator and blower assembly of the vehicle, preventing absorption of heat and moisture therefrom by the ambient air prior to entering the passenger cabin interior. Methods and HVAC systems for distributing ambient air to a motor vehicle passenger cabin are described also. |
