(Explained For Beginners)"},"content":{"rendered":"\n

Car vents are controlled by one or more actuators, fans, and the vacuum created by the engine. <\/p>\n\n\n\n

These parts work together to control where the air is directed if it\u2019s hot or cold, and the airflow volume.<\/p>\n\n\n\n

This Is What Controls Vents Airflow In A Car Cabin<\/h2>\n\n\n\n

Climate control modules in modern vehicles regulate and control the air ventilation system electronically by controlling three or four actuator motors that control the vents. A vacuum servo controls the air vents in older vehicles with a manual control system.<\/strong> <\/p>\n\n\n\t\t\t\t

    Car side vent with flow control<\/figcaption><\/figure>\n\n\n\n

    While driving, the engine creates a vacuum.<\/p>\n\n\n\n

    When the car moves, the entry point of the duct is in a high-pressure area, allowing air to be forced into the car from the front. Afterward, the heater warms it if necessary. The top of the car\u2019s hood is another common entry point.<\/p>\n\n\n\n

    There are vents on the dashboard and in the footwells that allow air into the car’s interior. You can adjust the vents so they face the front-seat passengers.<\/p>\n\n\n\n

    There are also ducts located behind the rear seat in some cars. A stream of warm air is blown onto the back passengers through slots in the ledge at the bottom, and by the front side windows in later cars. <\/p>\n\n\n\n

    All entry points on modern cars have flaps that can be opened and closed.<\/strong><\/p>\n\n\n\n

    Exit vents are located at the rear of the unit. A constant flow of air occurs as the car moves because they are in a low-pressure area.<\/p>\n\n\n\n
