What is the main purpose of ventilation in an HVAC context?

The main purpose of ventilation in an HVAC context is to provide fresh air and control moisture within a building. This process is crucial for maintaining indoor air quality, which directly affects the health and comfort of occupants. By introducing fresh air into indoor spaces, ventilation helps to dilute and remove indoor pollutants that can originate from various sources such as building materials, furniture, cleaning agents, and even human activities.

Moreover, controlling moisture levels is essential to prevent issues such as mold growth and structural damage. Excess moisture can lead to an environment that fosters mold, which can have serious health implications. Effective ventilation systems help to manage humidity levels, ensuring that they remain within a healthy range.

Implementing proper ventilation strategies not only supports the health of building occupants but also enhances overall energy efficiency by reducing the need for excessive heating or cooling, as the introduction of fresh air can help balance the temperature.
