What is the focus of ventilation in HVAC systems?

The focus of ventilation in HVAC systems primarily revolves around maintaining both air quality and temperature. Proper ventilation ensures that fresh air circulates throughout indoor spaces, which helps to dilute and remove indoor pollutants, enhance air quality, and regulate temperature within comfortable parameters. Effective ventilation systems are designed to bring in outdoor air while exhausting stale indoor air, which is essential for health and comfort.

While heating air is an important function of HVAC systems, particularly in colder climates, it is not the primary focus of ventilation itself. Similarly, while airflow can indeed cool spaces, ventilation encompasses more than just temperature control; it ensures that the air is clean and healthy. Enhancing humidity levels may be a component of some HVAC systems, but it is a separate issue from ventilation, which primarily targets air quality and temperature management. Thus, the emphasis on controlling both air quality and temperature captures the holistic purpose of ventilation within HVAC systems.
