Intake vents are openings in a building or vehicle designed to allow fresh air to enter. They play a crucial role in ventilation systems, helping to maintain air quality by bringing in outside air while expelling stale air. Properly placed intake vents can enhance energy efficiency and comfort by ensuring a steady flow of air. These vents can be found in various settings, including residential homes, commercial buildings, and automobiles. In HVAC systems, intake vents work alongside exhaust vents to create a balanced airflow, which is essential for regulating temperature and humidity levels indoors.
