| 摘要 |
The invention relates to an induction unit for uniting air flows, comprising at least one induction duct (21) coordinated with a primary air duct (30) and having an upstream end and a downstream end and a straight reference line (A) passing through the ends, and at least one first opening (28) for a primary air flow (F1), connected to the primary air duct (30) and opening with concurrent flow into the induction duct (21). The induction duct (21) has a secondary air intake (22) for the intake of a secondary air flow (F2) from a space surrounding the induction unit and an outlet (24) designed to return an air flow (F3) resulting from the primary air flow and the secondary air flow to the space surrounding the induction unit. The secondary air intake (22) is arranged at the upstream end of the induction duct (21) and is directed substantially parallel to the center line (A) thereof. |
