ABSTRACT:
This invention provides a method and apparatus for continuously moving gas from a first to a second location within an enclosed space. The gas is drawn from and exhausted to the exterior of the space. First, the gas is admitted from the exterior to a perforated plenum, and then the gas is moved at a relatively slow-speed out of the plenum toward the first location. The high-speed jet of gas is then originated at the first location within the slow-speed gas flow, and is directed toward the second location. This entrains additional gas from the first location and urges it toward the second. At the second location, the gas moving is exhausted to the exterior.
