What Type of Centrifugal Multi-Blade Fan Is Best for Underground Parking Garages?

With the increasing scarcity of above-ground parking spaces, underground parking garages have become the ideal solution. All buildings currently under construction are equipped with multi-level parking facilities. However, since underground parking garages are completely enclosed spaces, proper ventilation is a critical issue. Currently, all underground parking garages use duct-based ventilation. Which centrifugal multi-blade fan is suitable for underground parking garages? In addition to centrifugal multi-blade fans, there are also centrifugal multi-blade fans designed for duct-based ventilation. However, in the environment of an underground parking garage, there are additional requirements that must be met beyond general ventilation and exhaust. One such requirement is the exhaust of smoke in the event of a fire. In underground spaces, the removal of smoke from a fire takes precedence over general ventilation. Compared to centrifugal multi-blade fans, axial flow fans offer greater advantages in terms of smoke removal and exhaust. After being treated, a centrifugal multi-blade fan can operate continuously for approximately 30 minutes when the temperature reaches 200°C. Centrifugal multi-blade fans are characterized by their high airflow capacity. In a comprehensive fire protection system, centrifugal multi-blade fans are installed directly in the center of the ductwork and are primarily used to rapidly draw smoke into the ductwork and exhaust it outdoors. However, when the ductwork is excessively long, a centrifugal multi-blade fan must be installed to pressurize the ductwork and increase the exhaust velocity.
