The invention discloses a low-noise air-conditioning air duct for a railway vehicle. The air duct comprises an air duct body (1). An inner cavity of the air duct body is divided into a dynamic pressure cavity (7) with an air supply outlet (2) and a static pressure cavity (8) with air supply holes (801) evenly distributed in the bottom by a partition plate (9) arranged in the longitudinal directionof the air duct body. A row of air passing holes (901) are formed in the partition plate in the longitudinal direction, the static pressure cavity is communicated with the dynamic pressure cavity through the air passing holes (901), the air passing holes and the air supply outlet are formed at intervals, and the caliber of the air passing holes close to the air supply outlet is larger than that of the air passing holes far away from the air supply outlet. According to the invention, the uniformity of airflow distribution in the passenger room is improved, the noise in the passenger room is reduced, and the riding comfort of passengers in the passenger room is improved on the whole.
本发明公开了一种轨道车辆用低噪音空调风道,包括风道主体(1),所述风道主体的内腔被沿所述风道主体纵向设置的隔板(9)分隔为带有送风口(2)的动压腔(7)和底部均布送风孔(801)的静压腔(8),所述隔板的纵向设有一列过风孔(901),所述静压腔与所述动压腔通过所述过风孔(901)连通,且所述过风孔与所述送风口相隔一距离设置,靠近所述送风口的过风孔的口径大于远离所述送风口的过风孔口径。本发明既提高了客室气流组织的均匀性,同时也降低了客室内的噪音,整体上提升了客室内乘客的乘坐舒适性。
