AIR CONDITIONING DUCT FOR RAILWAY VEHICLE

PROBLEM TO BE SOLVED: To provide an air conditioning duct for railway vehicle capable of achieving further uniformization of temperature distribution in a passenger cabin, by performing a more appropriate air amount distribution of conditioned air.SOLUTION: An air conditioning duct 101 for railway vehicle extends in a vehicle length direction 11 at a vehicle ceiling part and supplies conditioned air generated in an air conditioner 180 to passenger cabins, and it includes a main duct 110, a chamber duct 120, a branch duct 130 and a guide part 140. The guide part is lower than the height of the main duct, extends to the branch duct from the main duct or a partition wall in the main duct in the vehicle width direction, and supplies one part of the conditioned air supplied to the main duct to the branch duct.SELECTED DRAWING: Figure 1 【課題】より適切な調和空気の風量配分を行い、客室内温度分布のより均一化を図ることが可能な鉄道車両用空調ダクトを提供する。【解決手段】 車両天井部にて車長方向１１に延在し、空調装置１８０で生成した調和空気を客室内に供給する鉄道車両用空調ダクト１０１であって、メインダクト１１０と、チャンバーダクト１２０と、分岐ダクト１３０と、ガイド部１４０とを有し、ガイド部は、メインダクトの高さよりも低く、かつ、車幅方向においてメインダクト又はメインダクト内の隔壁から分岐ダクトまで延在し、メインダクトへ供給された調和空気の一部を分岐ダクトへ供給する。【選択図】図１
