A Review of Ventilation and Environmental Control of Underground Spaces

Because of rapid urbanization, traffic problems, and other factors, underground spaces have been used more in the twenty-first century. Large are required for city, metro, tunnel, mine, industrial agricultural engineering, civil air defense engineering. Underground with varying thermal, ventilation, lighting environments can face problems comfort, health, safety. High temperatures, high humidity, difficulty flue gas emission, harmful microorganisms, radon, physical psychological examples issues. Air quality control technologies spaces, such as dehumidification, natural energy utilization, smoke extraction, ventilation resistance reduction, discussed. Ventilation smoke-proofing/evacuation is also extensively addressed.
