Description: Ventilation is the process of supplying fresh air to an enclosed space, which is essential for maintaining air quality in various environments, including buildings and vessels. This process not only involves the intake of outside air but also the circulation and renewal of indoor air, helping to eliminate pollutants, odors, and humidity. Ventilation is crucial for ensuring the health and well-being of occupants, as well as preserving the integrity of materials and equipment within the space. Ventilation can be natural, utilizing air currents and openings, or mechanical, using fan systems and ducts. Proper ventilation contributes to temperature and humidity regulation, creating a more comfortable and safe environment. Additionally, it is a key aspect of building design and construction, where factors such as the placement of openings, the efficiency of ventilation systems, and safety regulations must be considered. In summary, ventilation is an essential element in architecture, directly impacting the quality of life and durability of the environment.
