  • a space 91 surrounded by the upper end portion 35 of the side structure body 32 and the end-portion inclined surface 34a has the same height as that of the high roof portion A even within the range of the low roof portion B and is therefore comparatively high.
  • a slit 96 may be provided in a part of the ceiling panel 83b forming the circular conditioned air duct 80, and therefore part of conditioned air to be supplied from the conditioned air duct 80 to the inside of the passenger room may be supplied to the inside of the passenger room via the slit 96, and the other part of the conditioned air may be supplied to the inside of the passenger room via the discharging port 87.
  • conditioned air flowed into the conditioned air duct 80 is ejected in the substantially horizontal direction from a gap between the horizontal end portion 80ce and the ceiling panel 83b toward the center portion of the conditioned air duct 80 so as to cross a longitudinal direction of the conditioned air duct 80 (flow direction of conditioned air) while flowing through the circular conditioned air duct 80 in the longitudinal direction thereof, flows along a lower surface of the diffusion plate 88 forming the lighting device 81, and thereafter flows downward.
  • conditioned air ejected from the ejection port 87 does not directly blow against a passenger who sits in a seat in the passenger room belonging to the low roof portion B, and therefore the passenger is not made uncomfortable.
  • the conditioned air duct 80 is fabricated by combining a C-channel shape opening flow channel and the ceiling panel 83b, and therefore it is possible to minimize a clearance H2 (see Fig. 4 ) in the height direction between the low-roof structure body 34 and the ceiling panel 83b provided therebelow and secure a large ceiling height dimension H1 of the low roof portion.
  • a distance between the ejection port 87 of conditioned air and a passenger is increased, and therefore a ceiling height is secured and feeling of spaciousness is obtained.
  • ejected wind is ejected along the horizontal direction and thereafter moves downward, and therefore it is possible to reduce discomfort caused by directly sending ejected wind to a passenger and improve comfort.
  • the duct is formed by covering one surface of the channel material with the ceiling panel 83b, and therefore it is possible to fabricate the light-weight ceiling module 92 with a small manufacturing man-hour by using a small number of components, as compared to a case where an independent duct is arranged separately from the ceiling panel 83b.
  • the ceiling module 92 including the conditioned air duct only needs to be fixed to the low roof portion B, and therefore it is possible to construct a ceiling with a small manufacturing man-hour.
  • the exhaust air duct 86 and the conditioned air duct 89 having a large cross-sectional area can be housed in the spaces 91 between the upper end portions 35 of the side structure bodies 32 and the end-portion inclined surfaces 34a, and therefore it is possible to reduce flow rates of exhaust air and conditioned air flowing through those ducts. As a result, it is possible to reduce pressure loss and fluid sound of the ducts and power consumption of the air blower and prevent noise generated inside the ducts.
  • the invention is not only applied to a single railroad car having both sections, i.e., the high roof portion (general portion) A and the low roof portion B as in this example, but the above-mentioned effect exhibits also in a case where the invention is applied to, for example, a railroad car (railway vehicle) only having a roof portion that cannot secure a satisfactory ceiling height in a relationship with a loading gauge.
  • Fig. 7 is a horizontal sectional view (corresponding to Fig. 3 ) of a high ceiling portion and a low ceiling portion in Example 2
  • Fig. 8 is a cross-sectional view (H-H cross-section in Fig. 7 ) of an end portion in a width direction of the low ceiling portion in this example, which crosses a longitudinal direction.
  • a conditioned air duct 90 has one end connected to the connecting duct 93 and has the other closed end 90a and forms sides of a substantially rectangular shape in a planar view.
  • a shape of the conditioned air duct 90 in a planar view is different from the shape thereof in Example 1.
  • the conditioned air duct 90 is the same as the conditioned air duct in Example 1 in that, for example, the conditioned air duct 90 is formed by combining a C-channel member having an opening portion and the ceiling panel 83b and the conditioned air duct 90 has the ejection port 87 for ejecting conditioned air in the horizontal direction to supply the conditioned air to the inside of the passenger room.
  • two lines of lighting devices 81a are provided on the ceiling panel 83b along a longitudinal direction of the conditioned air duct 90 the first car 1a on the outside of the conditioned air duct 90 in the width direction.
  • a diffusion plate is not arranged on the ejection port 87 side from the conditioned air duct 90 toward the inside, and therefore a straightening plate 97 for guiding the flow 99 of conditioned air is arranged downstream of the ejection port 87 of the conditioned air duct 80.
  • the ceiling module 92 (see Fig. 5 ) is fabricated by fixing a C-channel opening flow channel to the ceiling panel 83b to form the conditioned air duct 80 and fixing the lighting devices 81a to the ceiling panel 83b.
  • This ceiling module 92 is lifted upward from the lower surface of the low-roof structure body 34, is positioned, and is thereafter fixed to the low-roof structure body 34 via the support portion 95.
  • conditioned air that has flowed into the conditioned air duct 80 is ejected in the substantially horizontal direction from the gap between the horizontal end portion 80ce and the ceiling panel 83b while flowing through the circular conditioned air duct 80, flows along the straightening plate 97, and thereafter flows downward. Therefore, conditioned air ejected from the ejection port 87 does not directly blow against a passenger in the passenger room belonging to the low roof portion B, and therefore it is possible to prevent the passenger from being made uncomfortable.
  • the conditioned air duct 80 is fabricated by combining the C-channel opening flow channel and the ceiling panel 83b, and therefore it is possible to reduce a dimension H2 (see Fig. 4 ) in the height direction of the ceiling portion of the low roof portion B and increase the ceiling height dimension H1 of the low roof portion.
  • a distance between the ejection port 87 of conditioned air and a passenger can be long, and therefore it is possible to reduce discomfort caused by an influence of ejected wind and improve comfort.
  • a terminal end portion 90b of the conditioned air duct 90 provided in the width direction of the first car 1a may be omitted, and there may be provided the conditioned air duct 90 that is extended in the width direction from the other end portion of the connecting duct 93 and then changes its direction to the longitudinal direction and is extended in the direction.
  • conditioned air to the passenger room having the low roof portion B can be supplied by the ceiling panel 83b including the conditioned air duct 90 having a simpler configuration.
  • conditioned air from the air conditioner only needs to be ejected in the horizontal direction to the inside of the passenger room via the ejection port while flowing through the air conditioning duct of the ceiling module in the longitudinal direction thereof, and a shape and the like thereof can be variously selected depending on a specification or form of the railroad car.
