The Basics of Residential Airflow

Airflow plays a pivotal role in our homes. It helps normalizes temperatures throughout a residence or the various zones within it. Proper airflow can also make a house energy efficient. It removes moisture from a home, which is good for our houses and our health, and it eliminates pollutants and contaminants. Read on to learn more about airflow.

Natural Ventilation and Air Pressure

All homes have some degree of natural ventilation, such as cracks and gaps. Older homes tend to have more, and newer homes tend to be more well-sealed. Natural ventilation occurs because air naturally moves from areas of high pressure to areas of low pressure.

Passive Ventilation

Many HVAC systems in San Antonio utilize passive ventilation, which takes advantage of the natural movement of air. A vent in the attic that allows attic air to normalize with the outside air is an example of this.

Mechanical Ventilation

There is also mechanical ventilation in many homes. An example would be an exhaust fan that draws old air out and thus forces more fresh air into the home. Many homes use supply-only ventilation, but exhaust-only ventilation has become a prevalent alternative over the years.

Air Distribution

There is also the matter of air distribution in most modern homes. Air distribution can be as simple as the conditioned air exhausted directly from a mini-split system or as complex as an air handler moving air through ductwork. Air distribution and ventilation systems have long been deeply connected, but in recent years, there has been a trend toward distinct ventilation and air distribution systems, such as with many approaches to balanced ventilation.
