Abstract
An air mixer for an air distribution system for a building including a set of fixed, parallel partitions arranged in a spaced-apart manner with one above another, these partitions forming alternating primary and secondary air passageways that are capable of conveying first and second air flows respectively. These passageways are substantially open ended at both inlet and outlet ends thereof. The primary air passageways extend from a first side of the mixer to a third, outlet side while the secondary air passageways extend at a substantial angle to the primary passageways from a second side to the third outlet side. There are fixed mixing devices, preferably in the form of curved vanes, arranged at many of the outlet ends of the passageways. The preferred air mixer has a substantially triangular shape in plan view.
