Abstract
The internal fan arrangement of an AHU is reconfigured by discharging directly from the scroll into a 90.degree. elbow. The bend of the elbow defines a converging section terminating in a throat which leads to a diverging section. Additionally, the ANC structure is located in the elbow with the noise sensing microphones being located at or near the fan outlet.
