Problems solved by technology

[0004] However, there are certain disadvantages in the two current air supply methods: when the air is supplied by the middle-top mesh plate, the mesh resistance at the end of the air supply is relatively large, resulting in a large air-conditioning pressure head and high noise, and the middle-top mesh plate The plate processing is complicated and the manufacturing cost is high; when the diffuser is used to supply air, the air is directly blown to the passengers, and the comfort is slightly poor

Abstract

The invention discloses an air supply system of a rail vehicle carriage. The air supply system comprises a carriage air supply passage arranged above a vehicle in-built roof. An air outlet of the carriage air supply passage is provided with a longitudinal beam section, the longitudinal beam section is internally provided with an air cavity, and a plurality of section air outlets are formed in the longitudinal beam section and located below the vehicle in-built roof. According to the air supply system, air is horizontally blown out from the top of a carriage, great airflow cannot exist in the carriage, and the comfort level is high in the carriage; and the air is buffered in the air cavity before being blown into the carriage, and the air speed is stable.

Description

Technical field [0001] The invention relates to an air supply system for rail transit vehicles, belonging to the technical field of air conditioning systems for rail transit vehicles. Background technique [0002] Rail transit vehicles have the advantages of large carrying capacity, fast traffic, and stable operation. They have gradually become popular in cities and become a recommended public transportation tool. At the same time, good ventilation performance must be ensured in the carriages of rail transit vehicles to ensure air circulation in the vehicles and provide passengers with good comfort. [0003] At present, rail transit vehicles use mid-top mesh plates or diffusers to supply air to the cabin, and use air ducts to send outside air to the roof mid-top mesh plates or diffusers, and the air passes through the roof mid-top mesh plates Or the diffuser flows into the compartment to form an air supply mode. [0004] However, the two current air supply methods both have certain...
