PURPOSE:To obviate the turbulence of conditioned air to stabilize the air to the laminar flow condition and improve the deflecting action of a deflector by providing a plurality of commutator plates increasing the height as they go downstream in the bend of a duct bent at about right angle upstream of the deflector. CONSTITUTION:A commutator plate 29 is disposed which is provided with a plurality of fins 30, 30 extending approximately at right angle to a duct 14 for a side vent upstream of a bend 14b thereof with the same width as the inflow side of a deflector 24 and increasing gradually their height as they go downstream of flow. Thus, conditioned air introduced in the duct 14 for the side vent under approximately laminar flow condition is adapted to change its direction at about right angle under the laminar flow condition and flow into the deflector 24 with the stable flow without producing any turbulence due to the bend 14b. Accordingly, a desired deflection of discharged conditioned air can be carried out by the deflector 24 to improve the deflecting action of the deflector 24. |
