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.
Description
technical field [0001] The invention relates to rail vehicle ventilation equipment, in particular to a low-noise air-conditioning air duct for rail vehicles. Background technique [0002] As a main component of rail vehicle passenger compartment, air-conditioning duct affects the ride comfort of passengers in the entire passenger compartment, thus putting forward higher requirements on the uniformity of air supply and noise level of rail vehicle air-conditioning duct. [0003] Due to the limited internal space of rail vehicles currently in use, the distance between the air-conditioning duct and the air outlet roof of the passenger compartment is very close, and the noise in the passenger compartment is relatively large; in addition, there are uneven air distribution in the passenger compartment, and temperature differences in different areas of the passenger compartment larger issues. Aiming at the problem of high noise from the air-conditioning duct into the passenger room...
