Description

  The present invention relates to an air conditioning facility for a vehicle that performs air conditioning inside the vehicle.

  Conventionally, air-conditioning equipment such as an air conditioner has been installed in a vehicle to comfortably hold the interior of a passenger cabin.

  In particular, in a vehicle of an orbital transportation system that travels on a track while being guided by a guide rail provided on the track, air is blown toward the center of the passenger cabin at the upper part of the longitudinal end in the passenger cabin. Air conditioning equipment is installed so that

  Thus, the air conditioner is installed only at the end of the vehicle cabin, and passengers near the center directly receive air from the air conditioner. For this reason, there was a possibility that comfort and amenity might be spoiled. In addition, since air is blown from the air conditioner toward the center, there is a possibility that the air conditioning effect to the end is not sufficient, that is, the air conditioning effect in the entire cabin is uneven, There was concern that comfort and comfort would be reduced.

  Here, for example, Patent Literature 1 discloses a ceiling duct arranged in a longitudinal direction on a ceiling portion in a passenger cabin. Further, the ceiling duct is provided with an air volume adjusting portion that tapers toward the both ends in the longitudinal direction, that is, the front-rear direction of the vehicle, in a gap that communicates the ceiling duct and a small duct that supplies conditioned air to the cabin. In addition, even at both ends of the vehicle, it is possible to supply the exhaust air uniformly into the cabin.

Japanese Examined Patent Publication No. 2-51762

  However, in the ceiling duct of Patent Document 1, the size of the gap communicating between the ceiling duct and the small duct is changed so that the conditioned air flows into the cabin uniformly. For this reason, although the same amount of conditioned air can be supplied to the same position in the width direction of the vehicle, the cross-sectional area of the vehicle in the longitudinal direction of the ceiling duct itself does not change, so the conditioned air is distributed to both ends in the longitudinal direction of the vehicle. That is still difficult. Therefore, there is a concern that the flow rate and flow velocity of the air-conditioning air supplied into the passenger compartment at the respective positions in the front-rear direction are different, and the air-conditioning in the passenger compartment cannot be made uniform.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide an air-conditioning facility and a vehicle that can achieve uniform air conditioning inside the vehicle and improve comfortability.

In order to solve the above problems, the present invention employs the following means.
That is, the air conditioning facility according to the present invention is a vehicle air conditioning facility that performs air conditioning inside the vehicle, and extends from the air source to the front and rear direction of the vehicle from the air source. The conditioned air is guided, and a main duct having a channel formed so that a cross-sectional area decreases as it goes from upstream to downstream of the conditioned air, and the conditioned air flowing through the channel is A supply port for supplying the interior of the vehicle in the width direction, and the flow path is provided symmetrically with respect to an axis along the front-rear direction in a pair in the width direction . An interior of the main duct is partitioned in the width direction, and an air conditioning plate defining a rectifying space is formed in front of the supply port. The air conditioning plate has a ventilation hole penetrating in the width direction, and the main air duct is formed. The duct is connected to the air flow path at a position close to the air source. And inclined provided to guide the conditioned air to the vents located adjacent to, and having an introduction plate for blocking a part of the conditioned air flow.
Moreover, the air conditioning equipment according to the present invention is an air conditioning equipment for a vehicle that performs air conditioning inside the vehicle, and is arranged at each of both ends in the front-rear direction of the vehicle to send conditioned air, A main duct having a flow path that extends along the front-rear direction of the vehicle and guides the conditioned air from the air source, and has a cross-sectional area that decreases from the upstream to the downstream of the conditioned air.

Furthermore, in this air conditioning equipment, the main duct may have an introduction plate that is provided in the flow path at a position close to the air source and blocks a part of the flow of the air conditioned air. Further, in this air conditioning equipment, the main duct has an air conditioning plate that partitions the inside of the main duct in the width direction and defines a rectifying space in front of the supply port, and the air conditioning plate includes the width adjustment plate. A ventilation hole penetrating in the direction may be formed.

According to such an air conditioning facility, since the cross-sectional area of the flow path itself decreases toward the downstream side, it is possible to distribute the conditioned air uniformly throughout the vehicle in the front-rear direction. Further, the flow paths are provided so as to be symmetrical in pairs in the width direction, and it is possible to supply conditioned air of the same amount and the same speed on both sides in the width direction. Therefore, the flow rate and flow velocity of the conditioned air flowing into the supply port can be maintained at the same amount at any position in the front-rear direction and the width direction of the vehicle. In addition, the main duct can reduce the range in which the conditioned air directly hits the passengers inside the vehicle. In addition, since the turbulent flow can be suppressed by the rectifying space of the air conditioning plate, the conditioned air can be supplied uniformly from the supply port to the inside of the vehicle, and the air conditioning inside the vehicle can be made more uniform. In addition, the introduction plate can prevent the conditioned air from flowing downstream to the supply port at a position close to the air source, so that the conditioned air can be reliably flowed into the supply port for further uniform air conditioning. Is possible.

  Further, the set of the flow paths in the main duct paired symmetrically with respect to the axis along the front-rear direction is provided symmetrically with respect to the axis along the width direction, paired with the front-rear direction. May be.

  In other words, the flow paths are provided symmetrically about the center in the longitudinal direction of the vehicle, and the conditioned air flows through each flow path independently. It becomes possible to spread. Therefore, the air conditioning inside the vehicle can be made more uniform.

  In addition, a louver may be provided in the ventilation hole.

  Such a louver suppresses the generation of turbulent flow around the ventilation hole, and makes it possible to further uniform the air conditioning.

  Moreover, the air conditioning equipment which concerns on this invention may be provided with the guide vane in the space formed in the connection part of the said ventilation source and the said main duct.

  Such a guide vane can suppress the occurrence of turbulent flow even when the conditioned air flows from the air source to the main duct, and can further achieve uniform air conditioning.

  Furthermore, the vehicle according to the present invention is provided at a position in the height direction between the ceiling plate constituting the ceiling, the ceiling decorative plate provided below the ceiling plate, and the ceiling plate and the ceiling decorative plate. Air conditioning equipment.

  In such a vehicle, since the air conditioning equipment is provided between the ceiling board and the ceiling decorative board, it is not necessary to separately manufacture and provide a main duct and a supply port in the air conditioning equipment. For this reason, the air conditioning can be made uniform while achieving cost reduction by reducing the weight and the number of parts.

  According to the air conditioning equipment and the vehicle of the present invention, it is possible to supply the same amount and the same speed of the conditioned air in the front-rear direction and the width direction inside the vehicle, and the air conditioning inside the vehicle can be made uniform. . Moreover, since the range in which the conditioned air directly hits the passengers inside the vehicle can be reduced, the comfortability can be improved.

  Moreover, as shown in FIG. 4, each of these ventilation holes 18 is provided with a louver 24 in which a plurality of slats 24a are arranged at predetermined intervals in the front-rear direction. Note that the louver 24 of the present embodiment employs a louver 24 in which the width dimension of the slat 24a, which is the width direction of the vehicle body 2, is 1 or more when the spacing between the slats 24a is 1. Yes.

  The flow path wall 23 is coupled to the ceiling decorative plate 20 and the ceiling plate 19 between the left and right partition plates 21 and the air conditioning plates 15 arranged on the left and right sides, and both ends of the left and right partition plates 21 in the front-rear direction. It is a plate-shaped member provided so as to gradually spread in the width direction toward the left or right in the width direction as it goes from the position to the installation position of the front and rear partition plates 22. That is, the flow path wall 23, the left and right partition plates 21, and the front and rear partition plates 22 form four independent flow paths FCA, that is, viewed from above or below. In this case, these four flow paths FCA have a rhombus shape.

  Here, in the four flow paths FCA, the right front is the first flow path FCA1, the left front is the second flow path FCA2, the right rear is the third flow path FCA3, and the left rear is the fourth flow path FCA4.

  The introduction plates 25 are provided one by one with the left and right partition plates 21 sandwiched symmetrically in the width direction left and right in the flow path FCA at positions near the air conditioners 11a and 11b at both ends in the front-rear direction of the vehicle body 2. It is a plate-shaped member, and is inclined from the center in the width direction toward the left and right from the top to the bottom as it goes in the front-rear direction. In other words, the first flow path FCA1 is provided to be inclined from the center in the width direction from the upper side to the lower side as it goes rearward, and from the upper side to the lower side as it goes rearward in the second flow path FCA2. Inclined toward the left from the center in the width direction. In addition, the third flow path FCA3 is provided so as to incline from the center in the width direction from the upper side to the lower side as it goes forward, and in the fourth flow path FCA4, from the upper side to the lower side as it goes forward. Toward the left from the center in the width direction.

  The introduction plate 25 is provided in the first flow path FCA1 and the second flow path FCA2 so as to facilitate the introduction of the conditioned air F into the ventilation holes 18 on both the left and right sides in the width direction formed at the end in the front-rear direction. Is installed so as to partially block the flow from the front to the rear of the conditioned air F, and the flow from the rear to the front in the third flow path FCA3 and the fourth flow path FCA4. That is, the introduction plate 25 partially blocks the flow from the upstream to the downstream of the conditioned air F.

  The supply port 14 is inclined at the both ends 20a in the width direction of the ceiling decorative board 20 smoothly from the lower side to the upper side toward the outer side in the width direction at the outer sides on the left and right sides in the width direction. A plurality of (in this embodiment, four locations on one side in the width direction) are formed to extend in the front-rear direction passing through the formed curved surface 19a and communicating the space S and the cabin PS inside the vehicle body 2. 8 openings in the entire vehicle body 2). The conditioned air F can be allowed to flow into the passenger compartment PS inside the vehicle body 2. Further, since the supply port 14 is formed on the curved surface 19a, the supply port 14 is not opened straight downward, but is slightly inclined toward the left and right in the width direction. That is, for example, in the first channel FCA1 and the third channel FCA3, the supply port 14 faces the lower right, and in the second channel FCA2 and the fourth channel FCA4, it opens toward the lower left.

  The connection duct 16 has a duct 17 that is paired on the left and right in the width direction. And while the one end of each duct 17 is connected to each blower outlet 12a, 12b of air conditioner 11a, 11b, the other end is formed in the position corresponding to the installation position of each duct 17. The channel FCA1, the second channel FCA2, the third channel FCA3, and the fourth channel FCA4 are connected. That is, the right outlet 12a in the front air conditioner 11a is connected to the front end of the first flow path FCA1, and the left outlet 12b in the front air conditioner 11a is connected to the front end of the second flow path FCA2. ing. Further, the right air outlet 12a in the rear air conditioner 11b is located at the rear end of the third flow path FCA3, and the left air outlet 12b in the rear air conditioner 11b is located behind the fourth flow path FCA4. Connected to the end.

  In addition, air-conditioning wind F blows straight from the air outlets 12a, 12b of the air conditioners 11a, 11b in the front-rear direction, and the first flow path FCA1, the second flow path FCA2, the third flow path FCA3, the fourth flow straight in the front-rear direction. As introduced into the path FCA4, one end and the other end of the duct 17 are formed to face in the direction along the front-rear direction.

  Furthermore, a plurality of guide vanes 17 a are erected from the inner surface facing downward or upward inside each duct 17 so as to follow the end face of the duct 17 in the width direction.

  In such a vehicle 1A, the conditioned air F blown from the air outlets 12a and 12b of the air conditioners 11a and 11b is formed in the main duct 13 in the first flow path FCA1, the second flow path FCA2, and the third flow. It is introduced into each of the channel FCA3 and the fourth channel FCA4.

  Here, for example, the conditioned air F introduced into the first flow path FCA1 circulates backward in the front-rear direction. At this time, since the flow path wall 23 is provided so as to be gradually inclined rightward in the width direction, the cross-sectional area of the first flow path FCA1 gradually decreases. Therefore, a sufficient flow rate can be maintained until the conditioned air F reaches the front and rear partition plates 22.

  In the second flow path FCA2, the third flow path FCA3, and the fourth flow path FCA4, the conditioned air F can be circulated uniformly in the front-rear direction as in the case of the first flow path FCA1. Furthermore, since the first flow path FCA1, the second flow path FCA2, the third flow path FCA3, and the fourth flow path FCA4 are arranged symmetrically in the left-right direction, the same amount of conditioned air F is distributed throughout the flow path FCA. It becomes possible.

  Further, since the flow path FCA is divided forward and backward by the front and rear partition plates 22, the conditioned air F from the air conditioners 11 a and 11 b at both ends of the vehicle main body 2 collides with the central portion of the vehicle main body 2 and is disturbed. It is possible to prevent the flow from occurring.

  Furthermore, the conditioned air F flowing through each of the first channel FCA1, the second channel FCA2, the third channel FCA3, and the fourth channel FCA4 flows into the space S through the ventilation holes 18 in the air conditioning plate 15, The flow rate of the conditioned air F is uniform over the entire area of the first flow path FCA1, the second flow path FCA2, the third flow path FCA3, and the fourth flow path FCA4. For this reason, the flow rate of the conditioned air F flowing into the space S from the ventilation hole 18 can be made equal. Therefore, the flow rate and flow velocity of the conditioned air F supplied from the space S through the supply port 14 into the cabin PS inside the vehicle body 2 are all uniform in the front-rear direction and the width direction.

  Moreover, since the louver 24 is provided in the ventilation hole 18 in the air conditioning plate 15, the conditioned air F flowing into the space S can be rectified to prevent the occurrence of turbulent flow around the ventilation hole 18, The conditioned air F can be smoothly flowed into the space S.

  Here, the louver 24 of the present embodiment has a length dimension in the width direction of 1 or more when the interval in the front-rear direction of the slats 24a is 1. However, in general, under this condition, the occurrence of turbulence can be prevented. It has been confirmed that when the interval is set to 1, the dimension in the width direction is 3 or more, and a further turbulent flow prevention effect can be obtained.

  In addition, the conditioned air F is supplied from the supply port 14 to the inside of the vehicle body 2 after flowing into the space S from the ventilation hole 18. Accordingly, rectification is performed again in the space S, and the occurrence of turbulent flow is suppressed and supplied to the inside of the vehicle main body 2, so that further uniform supply into the cabin PS can be achieved.

  Furthermore, when the conditioned air F is introduced from the air conditioners 11a and 11b to the first flow path FCA1, the second flow path FCA2, the third flow path FCA3, and the fourth flow path FCA4, the duct 17 of the connection duct 16 is supplied. The provided guide vane 17a suppresses the generation of turbulent flow due to the rectification of the conditioned air F, and as a result, the effect of equalizing the conditioned air F supplied to the inside of the vehicle body 2 can be further improved. .

  Moreover, although there exists a possibility that the air-conditioning wind F may flow into the ventilation hole 18 in the position close | similar to the air conditioner 11a, 11b here, in the present embodiment, since the introduction board 25 is provided, Since the air-conditioning air F is partially inclined to guide the air-flowing holes 18 at positions close to the air-conditioning apparatuses 11a and 11b, the air-conditioning air F can be supplied uniformly. Can be improved.

  Further, the supply port 14 does not face downward, and is inclined and opened to the left and right in the width direction, so that the conditioned air F does not directly hit the passenger in the passenger compartment PS, and the vehicle body 2 It distribute | circulates below the vehicle main body 2 along the edge part of right-and-left width direction, and circulates through the internal peripheral surface of the vehicle main body 2. For this reason, improvement in comfort and comfort and further improvement in air conditioning effect can be expected.

  According to the vehicle 1A of the present embodiment, the one flow path FCA1, the second flow path FCA2, the third flow path FCA3, and the fourth flow path FCA4 are provided symmetrically in the front-rear direction and the width direction. The uniform supply of the conditioned air F to the guest room PS becomes possible. Moreover, since the turbulent flow with respect to the conditioned air F can also be suppressed by the air conditioning plate 15, the louver 24 of the ventilation hole 18, the guide vane 17 a of the connection duct 16, and the introduction plate 25, the conditioned air F can be evenly distributed into the cabin PS. It can be supplied.

  In addition, passengers inside the vehicle body 2 do not receive air blown directly from the air conditioning equipment, so that comfort and comfort are improved, and the conditioned air F circulates from the left and right in the width direction inside the vehicle 1A. The effect of air conditioning can be improved.

  The flow path wall 54 is connected to the ceiling decorative plate 20 and the ceiling plate 19 between the left and right partition plates 21 and the air conditioning plate 15, and the rear partition plate 53 is installed from the center in the front-rear direction of the left and right partition plates 21. It is a plate-shaped member provided so as to gradually spread outward in the width direction toward the left or right in the width direction as it goes to the position. That is, the flow path walls 54, the left and right partition plates 21, and the rear partition plate 53 form two independent flow paths FCB that are triangular spaces S when viewed from above or below. Become.

  Here, in the two flow paths FCB, the right rear is the third flow path FCB3 and the left rear is the fourth flow path FCB4.

  The introduction plate 25 is a plate-like member that is provided one by one across the left and right partition plates 21 symmetrically in the width direction left and right within the flow path FCB at a position close to the air conditioner 41, and as it goes rearward. It is provided to be inclined from the upper side to the lower side from the center in the width direction toward the left and right. The introduction plate 25 allows the flow of the conditioned air F from the front to the rear so as to facilitate the introduction of the conditioned air F into the ventilation holes 18 on the left and right sides in the width direction formed at the front end. It is installed to block the part. That is, the introduction plate 25 partially blocks the flow from the upstream to the downstream of the conditioned air F.

  The supply port 14 has the same configuration as in the first embodiment.

  The connection duct 46 includes a front duct 46 a provided on the front side of the air conditioner 41 and a rear duct 46 b provided on the rear side. And the front duct 46a and the back duct 46b have the duct 17 which became a pair at the width direction right and left, respectively.

  Each duct 17 has one end connected to the air outlets 42 a, 42 b, 42 c, 42 d of the air conditioner 41 and the other end formed at a position corresponding to the installation position of each duct 17. The channel FCB1, the second channel FCB2, the third channel FCB3, and the fourth channel FCB4 are connected. That is, the right front outlet 42a is at the rear end of the first flow path FCB1, the left front outlet 42b is at the rear end of the second flow path FCB2, and the right rear outlet 42c is at the third flow path. The left rear outlet 42b is connected to the front end of the fourth flow path FCB4 at the front end of the FCB3.

  Then, as in the first embodiment, each duct 17 blows straight air conditioned air F in the front-rear direction from the air outlets 42a, 42b, 42c, 42d of the air conditioner 41, and the first flow path FCB1, One end and the other end of the duct 17 are formed to face in the direction along the front-rear direction so as to be introduced into the second flow path FCB2, the third flow path FCB3, and the fourth flow path FCB4. Furthermore, a plurality of guide vanes 17 a are erected from the inner surface facing downward or upward inside each duct 17 so as to follow the end face of the duct 17 in the width direction.

  In such a vehicle 1B, the conditioned air F blown from the air outlets 42a, 42b, 42c, 42d of the air conditioner 41 is formed in the main duct 43 in the first flow path FCB1, the second flow path FCB2, It is introduced into each of the third flow path FCB3 and the fourth flow path FCB4.

  Here, for example, the conditioned air F introduced into the first flow path FCB1 circulates forward in the front-rear direction. At this time, since the flow path wall 23 is provided so as to be gradually inclined rightward in the width direction, the cross-sectional area of the first flow path FCB1 gradually decreases. For example, the conditioned air F introduced into the third flow path FCB3 circulates backward in the front-rear direction. At this time, since the flow path wall 23 is provided so as to be gradually inclined rightward in the width direction, the cross-sectional area of the third flow path FCB3 also gradually decreases. Therefore, a sufficient flow rate can be maintained until the conditioned air F reaches the front partition plate 52 and the front partition plate 52.

  Similarly, in the second flow path FCB2 and the fourth flow path FCB4, the conditioned air F can be evenly distributed in the front-rear direction. Further, since the first flow path FCB1, the second flow path FCB2, the third flow path FCB3, and the fourth flow path FCB4 are arranged symmetrically in the left-right direction, the same amount of the conditioned air F is distributed throughout the flow path FCB. It becomes possible.

  Furthermore, as in the first embodiment, the occurrence of turbulent flow with respect to the conditioned air F can also be suppressed by the air conditioning plate 15, the louver 24 of the ventilation hole 18, the guide vane 17 a of the duct 17 of the connection duct 46, and the introduction plate 25, Further, the conditioned air F can be supplied into the guest room PS evenly.

  According to the vehicle 1B of the present embodiment, the first flow path FCB1, the second flow path FCB2, the third flow path FCB3, and the fourth flow path FCB4 are provided symmetrically in the front-rear direction and the width direction. The conditioned air F can be uniformly supplied to the passenger cabin PS inside, and the conditioned air F is also provided by the air conditioning plate 15, the louver 24 of the ventilation hole 18, the guide vane 17 a of the duct 17 in the connection duct 46, and the introduction plate 25. Therefore, the conditioned air F can be supplied uniformly.

The embodiment of the present invention has been described in detail above, but some design changes can be made without departing from the technical idea of the present invention.
For example, the louvers 24 do not need to be installed in all the ventilation holes 18 and may be applied to the ventilation holes 18 in which turbulent flow may occur in the vicinity.

  Furthermore, although the case where two air conditioners 11a and 11b are installed and the case where one air conditioner 41 is installed has been described in the above embodiment, the number and arrangement of the air conditioners 11a, 11b, and 41 are described. Is not limited to the above embodiment.

  Moreover, although the connection ducts 16 and 46 demonstrated the case where it was a different body from the main ducts 13 and 43, these may be integrated, for example.
