PROBLEM TO BE SOLVED: To provide a railroad vehicle capable of improving the comfort of passengers by suppressing radiation heat given from the surface of a ceiling interior panel forming a ceiling of a compartment.SOLUTION: A ceiling duct 53 connected to a hot air recovery fan 15 is disposed in a space S1 on a ceiling wall which is a space between a ceiling interior panel 21 configuring a ceiling of a railroad vehicle 100 and a heat insulating material 4. Ceiling suction ports 21a and load shelf upper suction ports 22a are opened and formed on the ceiling interior panel 21 to make the space S1 on the ceiling wall communicate with a compartment E12. Accordingly, air B in the space S1 on the ceiling wall is discharged to the outside of the compartment of the railroad vehicle 100 through the ceiling duct 53 to substitute the air B in the space S1 on the ceiling wall with conditioned air A, and a surface temperature of the ceiling interior panel 21 is brought closer to a temperature of the conditioned air A of the compartment E12. As a result, an influence of the radiation heat of the ceiling interior panel 21 is reduced to improve the comfort of passengers. |
