Air vents in buildings

Natural ventilation is the intentional passive flow of subaerial air into a building through planned openings (such as louvers, doors, and windows). In other instances, ventilation for indoor air quality contributes to the need for - and energy use by - mechanical heating and cooling equipment. IzfuwOyS7x7PeM,rt:ru:https://www.

Millions of Americans work in buildings with mechanical heating, ventilation, and air -conditioning (HVAC) systems; these systems are designed to provide air at comfortable temperature and humidity levels, free of harmful concentrations of air pollutants.
