NOISE-ATTENUATING SNORKEL DUCT FOR AIR-HANDLING SYSTEM RECIRCULATION VENT |
| 摘要 |
A vehicular air-handling system includes a blower assembly for a vehicle having a fan and a return-air baffle operable between a fresh-air position. The fan is in communication with a fresh-air duct and a recirculating position and the fan is at least partially in communication with a recirculating duct. A noise-attenuating end of the recirculating duct is positioned below an instrument panel of the vehicle and oriented substantially perpendicular to a portion of a floor below the instrument panel, wherein noise from the fan drawing air through the recirculating duct is directed into the floor below the instrument panel. |
