PROBLEM TO BE SOLVED: To provide an air-conditioning duct for a railway vehicle capable of uniforming an air-conditioning effect in a passenger room with a simple configuration.SOLUTION: In the air-conditioning duct for a railway vehicle, a guide plate is arranged on a main duct with which the air-conditioning duct is equipped. The guide plate guides a part of conditioned air to a front branch duct 23 by changing the flowing direction of the part of the conditioned air supplied from an air conditioner to the main duct. A blowout passage 40b is disposed over the entire length of the front branch duct 23, and the passage 40b supplies the conditioned air flowing in the front branch duct 23 in the direction inverse to the conditioned air before guidance by the guide plate from the front branch duct 23 to the inside of a passenger room located below the main duct. A wind direction plate 42 is disposed in at least a blowout passage 40b and guides the direction of the conditioned air flow so that the conditioned air flows vertically downward, or flows obliquely downward so that the downward side becomes the side close to the guide plate.SELECTED DRAWING: Figure 4
【課題】簡単な構成で客室内の空調効果を均一にすることができる鉄道車両用空調ダクトを提供する。【解決手段】車両用空調ダクトが備えるメインダクトにはガイド板が配置され、このガイド板は、空調機からメインダクトへ供給された調和空気の一部が流れる方向を変更して当該一部の調和空気を前位分岐ダクト23へ案内する。前位分岐ダクト23の全長にわたって吹出し通路40bが配置され、この吹出し通路40bは、前記ガイド板で案内される前の調和空気と逆向きで前位分岐ダクト23において流れる調和空気を、メインダクトよりも下方に位置する客室内に前位分岐ダクト23から供給する。風向板42は、少なくとも吹出し通路40bに配置され、調和空気が鉛直下方に流れるように、又は下方が前記ガイド板に近い側となる斜め下方に流れるように、調和空気が流れる方向を案内する。【選択図】図4
