General ventilation is a method used to improve indoor air quality by replacing stale air with fresh outdoor air. This process helps to dilute indoor pollutants, such as dust, smoke, and odors, making the environment healthier for occupants. It can be achieved through natural means, like open windows, or mechanical systems, such as fans and air conditioning units. In buildings, general ventilation is essential for maintaining comfort and safety. It regulates temperature and humidity levels, preventing issues like mold growth and excessive heat. Proper general ventilation systems are designed to meet specific standards, ensuring that they effectively circulate air throughout the space.
