DEFINITION

Classification: 165/213

Mixing within zone of recirculated zone air and supply air adjacent zone inlet(e.g., induction unit, etc.):

(under subclass 212) Subject matter wherein an air inlet discharges heated or cooled supply air from the common air supply source to said distinct area; and further including means transporting used air from a location within the distinct area to a location at or near the air inlet for mixing the used air with the supply air.
