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
The present invention relates to a kind of rail traffic vehicles compartment supply air system, belong to the a/c system technical field of rail traffic vehicles.
Background technology
It is large that rail traffic vehicles has bearing capacity, and traffic is quick, and the advantage such as operate steadily, slowly universal in city, becomes a kind of bus tool of recommendation.Meanwhile, in the compartment of rail traffic vehicles, to good ventilation performance be ensured, guarantee vehicle inner air flow, to the comfort level that passenger is good.
Current track vehicular traffic pushes up mesh plate in utilizing or air diffuser is blown in compartment, and adopt air channel to be delivered in roof by outside air and push up in mesh plate or air diffuser, air in roof, push up mesh plate or air diffuser flow in compartment, forms air supply pattern.
But two kinds of current air supply modes all exist certain drawback: when pushing up mesh plate air-supply in employing, air-supply end mesh resistance is comparatively large, causes that air-conditioning pressure head is comparatively large, noise is higher, and middle top mesh plate processed complex, manufacturing cost is high; When adopting diffuser feeding, air-supply directly blows to passenger, and traveling comfort is slightly poor.
Summary of the invention
In order to solve above-mentioned Problems existing, the invention discloses a kind of rail traffic vehicles compartment supply air system, its concrete technical scheme is as follows:
A kind of rail traffic vehicles compartment supply air system, comprise the air delivery duct, compartment be arranged on above the in-built top board of vehicle, the air outlet of air delivery duct, described compartment is provided with longitudinal beam section bar, described longitudinal beam section bar inside is provided with wind chamber, the top of described longitudinal beam section bar is provided with several section bar air outlets, and described section bar air outlet is positioned at below the in-built top board of vehicle.
The top of described longitudinal beam section bar is provided with and connects flat board, and the surrounding that described connection is dull and stereotyped and the in-built top board of vehicle are connected and fixed, and connect flat board and be provided with several section bar ventilation inlets, the air outlet of described section bar ventilation inlet and air delivery duct, compartment is through.
Below the section bar air outlet of described longitudinal beam section bar, limited aerofoil is set, between the section bar air outlet of described arbitrary neighborhood, is provided with joint pin, the side plate of described joint pin longitudinal beam connected section bar and limit aerofoil.
The side plate of described longitudinal beam section bar and the in-built mounting of roof plate of vehicle are fixed.
Gap is left between described section bar air outlet and the bottom in wind chamber.
Principle of work of the present invention is:
The in-built top board of vehicle of the air outlet of section bar described in the present invention junction is parallel with limit aerofoil.
The wind that air-conditioning is sent is transported to air delivery duct, compartment, divide the wind chamber entering into longitudinal beam section bar through air delivery duct, compartment, then go out from section bar air outlet, after wind is gone out from section bar air outlet, the limit aerofoil of the in-built top board of the vehicle above section bar air outlet and below forms the horizontal channel of wind flow, and wind can only blow out from vehicle in-built top board servant quarters level, from whole compartment, wind, from the blowout of compartment inner top level, directly can not blow to the passenger in compartment, to the sensation of occupant comfort.
The in-built top board of vehicle of the air outlet of section bar described in the present invention junction tilts with limit aerofoil.The parallel blowout of wind part blown out from air outlet, the downward-sloping diffusion of part.
According to the demand of use occasion, it is parallel with the in-built top board of vehicle of section bar air outlet junction or tilt that air-supply plate is set.
The present invention, the wind that air-conditioning is sent enters into wind chamber, and wind forms a buffer gas flow in wind chamber, first wind be flushed to the bottom in wind chamber, and then rise, and the position that wind is rising to section bar air outlet is gone out from section bar air outlet, the velocity ratio of wind comparatively relaxes, and wind speed is steady.
Beneficial effect of the present invention:
The present invention, wind is from the blowout of car body top level, and interior does not have larger air-flow, and compartment comfort inside is better.
The present invention, wind is blown into before in compartment and cushions in wind chamber, and wind speed is steady.
