A cooling ventilation system is a type of mechanical system that is designed to regulate the temperature and air quality of a space. It works by bringing in fresh air from outside and circulating it throughout the space. This air is then cooled or heated depending on the desired temperature. The system also helps to remove any contaminants or pollutants from the air, ensuring a healthier environment. Additionally, the system helps to reduce humidity levels, which can be beneficial in certain climates. The system is usually composed of several components, such as fans, filters, ducts, and vents. It is important to have a properly installed and maintained cooling ventilation system in order to ensure that the space is comfortable and healthy.
