Abstract

The invention belongs to the technical field of air conditioners for rail vehicles, and discloses an air conditioning unit and air duct system for a seating-sleeping dual-purpose rail vehicle. The system comprise an air conditioning unit arranged on the top of the rail vehicle and a main air duct, the main air duct comprises a dynamic pressure cavity area and a static pressure cavity area, the dynamic pressure cavity area is communicated with the air conditioning unit to supply air to corridors of the rail vehicle, and the static pressure cavity area is communicated with the dynamic pressure cavity area to supply air to carriages of the rail vehicle. According to the system, the structure that the dynamic pressure cavity area is communicated with the air conditioning unit and the static pressure cavity area is communicated with the dynamic pressure cavity area is adopted, the dynamic pressure cavity area supplies air to the corridors, the static pressure cavity area supplies air to the carriages, therefore, the air speed of the cold air entering the carriages is greatly decreased, and the riding comfort is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners for rail vehicles, in particular to an air conditioner unit and an air duct system for both seat and sleeping rail vehicles. Background technique [0002] At present, most of the rail vehicles in our country are seat cars. Due to the long lines of some trains in my country, the passengers are easily fatigued and should not be operated at night due to the long-term use of the cars in China. The occupancy rate of sleeper cars is low when used during the day, and the sleeper is also used as a seat car. Not suitable. Therefore, a dual-use rail vehicle appeared, which was used as a sleeping car at night and used as a seat car during the day. Since people have poor resistance when falling asleep, the air supply speed of the air conditioner in the sleeping car should not be too large, and most of the passengers in the car are in a awake state, so there is no need to consider this problem...
