HVAC airflow is the process of controlling the flow of air in a space to ensure the desired temperature, humidity, and air quality are maintained. It is a key component of HVAC systems, which are responsible for providing comfortable and healthy indoor air. HVAC airflow is achieved through the use of air ducts, fans, and other components that move air throughout the space. Airflow is regulated through the use of dampers, filters, and other components that can be adjusted to achieve the desired air quality. The air flow rate is also important, as it determines how quickly the desired temperature, humidity, and air quality can be achieved. Proper airflow is essential for ensuring the health and comfort of occupants in a space, as well as for energy efficiency.
