Recirculated Air

Air that is removed from a space by mechanical means and reused again as supply air. Using a mix of recirculated air and fresh air is efficient because it maintains healthy levels of oxygen at healthy levels but doesn’t require excessive amounts of conditioning (heating or cooling).
