Basement ventilation systems operate in Normal Mode and Fire Mode. Normal Mode maintains air quality by removing vehicle exhaust gases using sensors, jet fans, and exhaust fans. When a fire is detected, the system switches to Fire Mode, where smoke exhaust fans run at full capacity and airflow is directed to remove smoke quickly, improving visibility and ensuring safer evacuation and firefighting operations.

Calculating the Air Change Rate (ACH) is essential for designing effective basement car park ventilation systems. ACH determines how many times the total air volume in a parking garage is replaced every hour to remove harmful vehicle exhaust gases such as carbon monoxide and nitrogen oxides. By calculating the car park volume and applying the required ACH value, engineers can determine the airflow needed to maintain safe air quality and comply with ventilation standards.

Choosing the right ventilation system is essential for safe basement car park operations. Traditional ducted ventilation systems use extensive duct networks to remove contaminated air, while jet fan systems move air using high-velocity fans without large ductwork. Understanding their differences helps engineers and developers select the most efficient solution based on space, cost, and performance requirements.
