[0002] In modern buildings, ventilation duct installation is an essential component of architectural design. It requires a rational layout based on factors such as the building's structure, intended use, and occupancy density to ensure smooth air circulation and a comfortable indoor environment. Furthermore, ventilation duct installation must comply with relevant building codes and standards to ensure safety and reliability.
