US Patent 10101238 Integrated ventilation and leak detection system and method of assembly

A ventilation and leak detection system for use in an enclosure includes a ventilation duct extending at least partially through an interior chamber defined in the enclosure. The ventilation duct includes at least one inlet end positioned within a lower portion of the interior chamber and an outlet end. The at least one inlet end includes at least one opening defined therein and sized to enable air and fuel within the enclosure to be drawn into the ventilation duct to ventilate the enclosure. The system further includes a detection unit coupled in flow communication with the ventilation duct proximate to the outlet end for detecting fuel entrained within flow drawn into the ventilation duct.
