Ventilation in an HVAC serves two primary purposes: to remove stagnant indoor air and to bring in purified air. The process of ventilation involves the exchange of air between the indoor and outdoor environments. The air inside a building contains pollutants such as airborne toxins, particulate matter, and carbon dioxide, which can negatively impact air quality and occupant health.
There are several types of ventilation systems available, each with its own unique characteristics and applications. The main types of ventilation systems include:
Building Ventilation involves using windows to exchange air between the indoor and outdoor environments. Natural ventilation is often used in conjunction with solar energy harvesting.

Air Removal Systems involves using exhaust blowers to remove stale air from a building. Exhaust ventilation is often used in restaurants and other areas where indoor pollutants are present.
Supply Ventilation involves using air supply blowers to bring new air into a building. This type of ventilation is commonly employed in residential and commercial buildings where occupants require a high level of indoor air quality.
When choosing a ventilation system, several factors need to be considered, including:
Building size and layout: The ventilation system should be designed to meet the specific needs of the building, taking into account its shape.
Building usage: The ventilation system should be designed to provide a suitable level of air exchange based on the number of occupants in the building.
Environmental conditions: The ventilation system should be designed to accommodate the local climate, taking into account wind patterns.
Indoor air pollutants: The ventilation system should be designed to remove indoor air pollutants such as airborne pathogens.
Regular care and upkeep of the ventilation system is essential to ensure its continued performance and effectiveness. Regular system checks can help to identify potential issues and prevent costly repairs.
In conclusion, understanding the basics of air circulation systems is essential for maintaining a comfortable and healthy indoor environment. By choosing the right ventilation system and performing regular routine checks, building occupants can enjoy improved productivity.
