  However, in the configuration of Patent Document 1, the air conditioning target by the air conditioning indoor unit is a living room in which the air conditioning indoor unit is installed. To add another room to the air conditioning target by the air conditioning indoor unit, the air conditioning duct is added to the air conditioning indoor unit. Need to be connected, and the conditioned air needs to be transported to other living rooms through the air conditioning duct. Here, in the configuration using an air conditioning duct for transporting conditioned air, it is assumed that the air conditioning duct is installed in the ceiling space, but by securing the installation space of the air conditioning duct in the ceiling space, There is concern that the height of the ceiling will be lowered by that amount and the living space such as the living room will be narrowed.

  The present invention has been made in view of the above circumstances, and has a main object of suitably air-conditioning a plurality of living rooms without using an air-conditioning duct for transporting conditioned air to the living rooms.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary.

  A building according to a first aspect of the present invention is a building that includes a partition wall that partitions a corridor and a living room adjacent to each other, and is provided with an air-conditioning facility that performs air-conditioning of the living room. The air conditioner has a blowing portion at a position for blowing along the ceiling surface or a position for blowing along the floor surface of the hallway, and the partition wall has the air conditioner flowing along the ceiling surface. An inflow portion is provided at a position where air flows into the living room or a position where the conditioned air flowing along the floor surface flows into the living room.

In this case, even if it is assumed that a configuration for supplying conditioned air to a plurality of rooms is realized, there is no need to install an air conditioning duct for each room in the hallway or the ceiling space of the room. Therefore, it can be avoided that the living space such as the corridor and the living room becomes narrow by expanding the ceiling space. Moreover, since the conditioned air flows along the ceiling surface or floor surface of the hallway and flows into the living room as it is, the conditioned air is difficult to diffuse throughout the interior area of the hallway. For this reason, it can suppress that the air-conditioning effect by a conditioned air is provided to a corridor and the air-conditioning efficiency in a living room falls. As described above, a plurality of living rooms can be suitably air-conditioned without using an air-conditioning duct for transporting conditioned air to the living rooms.

  According to the fifth aspect, when the conditioned air flows along the ceiling surface of the upper ceiling portion in the hallway, it is possible to realize a configuration in which the conditioned air easily flows into the living room from the inflow portion. In this case, unlike the configuration in which the inflow portion is disposed at a position lower than the lower ceiling portion, the conditioned air present at a position higher than the ceiling surface of the lower ceiling portion is less likely to flow into the living room. The inconvenience that efficiency falls can be suppressed.

  In a sixth invention, in any one of the third to fifth inventions, a recess recessed toward the partition wall is provided between the lower ceiling portion and the upper ceiling portion. It is provided so as to extend along the ceiling surface.

  According to the sixth aspect, since the conditioned air flows through the inside of the recess in the inner region of the folded-up portion of the ceiling, the conditioned air can be prevented from diffusing downward from the lower ceiling portion. Moreover, since indirect lighting can be constructed in the corridor by installing a lighting fixture inside the recess, a space for flowing conditioned air instead of a dedicated area for flowing conditioned air inside the recess And a space for installing a lighting fixture.

  In addition, when the conditioned air is cooling air for cooling, the cooling air is easy to flow down, so that the cooling air flowing along the ceiling surface of the upper ceiling part is restricted by the lower ceiling part. Is effective in increasing the cooling efficiency of the room.

  According to a seventh aspect, in the sixth aspect, the recess is provided so as to extend along a blowing direction of the blowout portion, and the blowout portion has the conditioned air on the ceiling surface of the upper ceiling portion. It is provided in the position which blows off this conditioned air in the above-mentioned crevice so that it may flow along.

  According to the seventh aspect, since the conditioned air is blown out toward the inner region of the recess in the inner region of the folded-up portion, it is possible to realize a configuration in which the flow of the conditioned air is regulated by the lower ceiling portion.

  According to an eighth invention, in any one of the second to seventh inventions, the hallway includes a first hallway lower part and a second hallway lower part branched from the first hallway lower part, The blow-out part is provided at a position where the conditioned air is blown out so that the conditioned air flows toward the lower part of the corridor via a branch part between the lower part of the first corridor and the second corridor. The means includes distribution means for distributing the guide destination of the conditioned air to the lower part of the first corridor and the lower part of the second corridor.

  According to the eighth aspect, in the configuration for supplying the conditioned air to the plurality of living rooms, the supply destination of the conditioned air can be switched. That is, it is possible to appropriately select a room to be air-conditioned.

  In a ninth aspect based on any one of the first to eighth aspects, the inflow portion is provided with an inflow fan that allows the conditioned air to flow into the living room from the corridor through the inflow portion.

  According to the ninth aspect of the present invention, the amount of conditioned air flowing into the room can be increased by driving the inflow fan, and consequently the air conditioning efficiency of the room can be increased.

  In a tenth invention, in any one of the first to ninth inventions, the air conditioning equipment has a return air section that takes in the air in the hallway as return air, and the partition wall includes An outflow part for allowing air to flow out into the corridor is provided, and in the configuration in which the conditioned air flows along the ceiling surface of the corridor, the return air part is disposed below the blowout part, and the outflow part is In the configuration in which the conditioned air flows along the floor surface of the corridor, the return air portion is disposed above the blowout portion, and the outflow portion is above the outflow portion.

  The machine room 22 is arranged on the opposite side of the first living room 14A across the hallway 15, and the hallway 15 is arranged so as to extend with the arrangement direction of the machine room 22 and the first living room 14A as a longitudinal direction. . The machine room 22 is disposed between the third living room 14C and the fourth living room 14D. The second living room 14B is arranged side by side along the hallway 15 in the third living room 14C, and the hallway 15 is arranged between the second living room 14B and the third living room 14C and the fourth living room 14D. .

  As shown in FIGS. 2 and 3, a lighting fixture 25 is installed in the hallway 15, and indirect lighting is configured by the lighting fixture 25 in the hallway 15. The hallway ceiling 31 of the hallway 15 includes a lower ceiling part 34 and an upper ceiling part 35 that forms a ceiling surface at a position higher than the lower ceiling part 34. The lighting fixture 25 is installed between the unit 35. In this case, the luminaire 25 as a light source is in a state of being covered and hidden from below by the lower ceiling portion 34.

  The hallway ceiling 31 of the hallway 15 is provided with a folded-up portion that is partially folded upward and a non-folded-up portion that is not folded up. A side ceiling portion 34 is formed, and an upper ceiling portion 35 is formed by the folded-up portion. Here, when the internal space of the folded-up part is the folded region 36, the folded region 36 corresponds to a region above the ceiling surface of the lower ceiling portion 34 in the hallway 15.

  In addition, the ceiling surface of the upper ceiling part 35 is arrange | positioned in the same height position as the ceiling surface of each room ceiling 41 of living room 14A-14D, and if the upper ceiling part 35 is made into the reference | standard, the corridor ceiling 31 will fall and the ceiling It can be said that it has. In this case, the upper ceiling part 35 serving as a reference forms a non-falling ceiling, and the lower ceiling part 34 forms the falling ceiling.

  In the corridor ceiling 31, a concave portion 38 that is recessed outward from the folded-up portion is formed, and an inner area of the concave portion 38 is an installation space for the lighting fixture 25. The recessed portion 38 is in a state where the side surface of the lower ceiling portion 34 is recessed toward the inside of the lower ceiling portion 34 at the step portion between the lower ceiling portion 34 and the upper ceiling portion 35. It is arranged between the ceiling part 34 and the upper ceiling part 35. In this case, the inner region of the recess 38 is included in the folded region 36.

  The lower ceiling portion 34 extends from the partition wall 11 toward the corridor 15 at a position spaced downward from the upper ceiling portion 35, and the recessed portion 38 includes the lower ceiling portion 34, the upper ceiling portion 35, and the partition wall. 11. On the inner peripheral surface of the recess 38, the upper facing surface is formed by the lower surface (ceiling surface) of the upper ceiling portion 35 among the pair of facing surfaces that vertically oppose across the open side of the recess 38, and the lower side Is formed by the upper surface of the lower ceiling portion 34. Further, the surface of the recess 38 opposite to the open side is formed by the side surface (wall surface) of the partition wall 11.

  The lower ceiling portion 34 is disposed at a position lower than the upper ceiling portion 35, while being disposed at a position higher than the entrance / exit 16. That is, the lower ceiling part 34 is disposed between the upper ceiling part 35 and the doorway 16. For this reason, even if the hallway ceiling 31 has the lower ceiling part 34, when the resident etc. enter / exit the entrance / exit 16, the lower ceiling part 34 does not become obstructive.

  The lower ceiling part 34 and the upper ceiling part 35 include a ceiling base material such as a ceiling beam or a field edge, and a ceiling surface material such as a gypsum board attached to the ceiling base material. In a portion of the lower ceiling portion 34 where the concave portion 38 is formed, a mounting plate such as a gypsum board forming a mounting surface is installed on the ceiling base material, and the lighting device 25 is placed on the mounting plate. Is placed. Thereby, it can suppress that the lighting fixture 25 installed on the lower side ceiling part 34 becomes an unstable state.

  The lower ceiling portion 34 is provided with an upright portion 39 that rises upward from the tip thereof (the end portion on the side opposite to the partition wall 11). The upright portion 39 has a function as a blindfold that hides the luminaire 25 installed on the lower ceiling portion 34 from being exposed obliquely downward through the open side of the recess 38. Thereby, it can suppress that the lighting fixture 25 as a light source enters into view of a resident etc. in the corridor 15. FIG.

  In the partition wall 11, a wall material such as a gypsum board is attached to the wall base material both above and below the lower ceiling portion 34. Moreover, in the partition wall 11, the part near the upper end between the lower ceiling part 34 and the upper ceiling part 35 protrudes toward the corridor 15 side from the lower part of the lower ceiling part 34, and below that The thickness dimension is larger than the part. In this case, in the width direction of the hallway 15, the width dimension of the area above the ceiling surface of the lower ceiling part 34 is smaller than the width dimension of the area below the ceiling surface of the lower ceiling part 34. . In addition, in the partition wall 11, the upper part of the lower side ceiling part 34 does not need to be set as the structure protruded to the corridor 15 side rather than the lower part.

  As shown in FIGS. 1 to 4, the lower ceiling portion 34 extends along the peripheral edge of the hallway 15, and the folded region 36 is surrounded by the lower ceiling portion 34 from all sides. Yes. In this case, the folded region 36 extends along the longitudinal direction of the hallway 15. Similarly to the lower ceiling portion 34, the recess 38 and the standing portion 39 also extend along the peripheral edge of the hallway 15. The projecting dimension of the lower ceiling portion 34 from the partition wall 11 is smaller than ½ of the width dimension of the hallway 15.

  In the present embodiment, conditioned air is blown out from the air conditioning indoor unit 21 of the machine room 22 to the hallway 15, and the conditioned air flows along the ceiling surface of the hallway ceiling 31 and flows into the rooms 14 </ b> A to 14 </ b> D. Air conditioning is performed.

  As shown in FIG. 4, in the air conditioning indoor unit 21 in the air conditioning facility, a blowout part 51 that blows the generated conditioned air into the hallway 15 and a return air part 52 that takes in the air in the hallway 15 as return air, respectively, are air conditioning ducts. Connected through. The blow-out part 51 and the return air part 52 each include a grille, and are respectively attached to openings that penetrate the partition wall 11 between the hallway 15 and the machine room 22. The air conditioning indoor unit 21 has an air conditioning fan that includes an electric motor. By driving the air conditioning fan, the air conditioning air is blown out from the blowing unit 51 and the return air is taken in from the return air unit 52. .

  The blowing part 51 is disposed between the lower ceiling part 34 and the upper ceiling part 35 at a position higher than the ceiling surface of the lower ceiling part 34 of the hallway 15. In this case, the blowing part 51 is disposed in the vicinity of the ceiling surface of the upper ceiling part 35. In the blowing part 51, it sets with a grill etc. so that the direction which blows off air-conditioning air may become parallel to the longitudinal direction of the corridor 15, and may become a horizontal direction or a little diagonally upwards. The blow-out unit 51 blows out the conditioned air toward the inside of the folded region 36, and the blown-out conditioned air is directed toward the first living room 14 </ b> A on the opposite side of the corridor 15 from the blow-out unit 51. Then, it flows along the ceiling surface of the upper ceiling portion 35. In this case, the lower ceiling part 34 constitutes a guiding means for guiding the flow of conditioned air.

  The return air part 52 is disposed below the blowing part 51. The return air section 52 is disposed, for example, near the floor surface of the corridor 15, and air near the floor surface of the corridor 15 is taken in along with the blowing of conditioned air from the blowing section 51. The air in the hallway 15 may be taken in from the return air part 52 through the undercut of the door 17. In this case, the return air part 52 has the undercut of the door 17.

  As shown in FIG. 2, in the width direction of the corridor 15, the blowout parts 51 are arranged at positions near both ends, and the return air part 52 is arranged at an intermediate position. Each blowing part 51 is disposed above a portion of the lower ceiling part 34 that extends along the longitudinal direction of the corridor 15, and the conditioned air blown from these blowing parts 51 passes through the inner peripheral surface of the recess 38. Along the longitudinal direction of the hallway 15. In this case, the flow of the conditioned air toward the lower side of the lower ceiling portion 34 is restricted by the lower ceiling portion 34, and the conditioned air is less likely to flow downward from the open portion of the folded region 36. In addition, the lower ceiling part 34 is corresponded to the regulation means which regulates the flow of conditioned air. Further, in this case, the conditioned air itself is prevented from flowing out from the recess 38 by the standing portion 39, and the conditioned air is less likely to flow out from the recess 38 to the side.

  Returning to the description of FIG. 4, the partition wall 11 is provided with an inflow portion 53 through which conditioned air can flow into the living rooms 14 </ b> A to 14 </ b> D from the corridor 15. The inflow portion 53 has a vent hole penetrating the partition wall 11 and a grille attached to the vent hole. The inflow portion 53 is disposed between the lower ceiling portion 34 and the upper ceiling portion 35 at a position higher than the ceiling surface of the lower ceiling portion 34 of the hallway 15, similarly to the blowout portion 51. In this case, the inflow portion 53 is disposed in the vicinity of the ceiling surface of the upper ceiling portion 35, and the conditioned air that has flowed along the upper ceiling portion 35 in the folded region 36 passes through the inflow portion 53 to the living room 14 </ b> A. Will flow into ~ 14D.

  The inflow portion 53 is provided with an inflow fan 54 that forcibly flows the air in the hallway 15 into the living rooms 14A to 14D. The inflow fan 54 is configured to include an electric motor, and can rotate to increase the amount of ventilation in the inflow portion 53.

  The doors 17 of the living rooms 14 </ b> A to 14 </ b> D are provided with an outflow portion 55 that allows the air in the living rooms 14 </ b> A to 14 </ b> D to flow out into the hallway 15. The outflow part 55 has a vent hole penetrating the door 17 and a grille attached to the vent hole. Here, since the door 17 is provided at the entrance 16 of the partition wall 11, the outflow portion 55 is provided in the partition wall 11 even when provided in the door 17. The outflow portion 55 is disposed below the inflow portion 53. The outflow part 55 is arrange | positioned near the floor surface of living room 14A-14D, for example, and the corridor 15 passes through the outflow part 55 with the air near the floor surface of living room 14A-14D through inflow of the conditioned air from the inflow part 53. It has come to flow out. Note that the outflow portion 55 may be an undercut of the door 17.

  In the first living room 14A, the third living room 14C, and the fourth living room 14D, the inflow portion 53 is disposed right above the entrance / exit 16, and the inflow portion 53 and the outflow portion 55 are arranged vertically. . On the other hand, in the second living room 14B, the inflow portion 53 is not disposed directly above the entrance / exit 16, so that the inflow portion 53 and the outflow portion 55 are not lined up and down but shifted to the left and right. (See FIGS. 1 and 3). Since the inflow part 53 and the outflow part 55 are not lined up and down, the conditioned air that has flowed into the second living room 14B from the inflow part 53 reaches the entire second living room 14B before flowing out of the corridor 15 from the outflow part 55. It can be expected to become easier.

  As shown in FIG. 3, the inflow portion 53 of the first living room 14 </ b> A extends along the ceiling surface of the upper ceiling portion 35 in the width direction of the hallway 15. In this case, the inflow portion 53 is in a state of entering each of the concave portions 38 disposed on both ends in the width direction of the corridor 15, and the conditioned air that has flowed through the concave portions 38 and the concave portions 38. Both of the conditioned air that has flowed through the region between them easily flows into the first living room 14 </ b> A through the inflow portion 53.

  Next, the electrical configuration of the entire building air conditioning system will be described with reference to the block diagram of FIG.

  The entire building air conditioning system has a home server 61 as a control means. The home server 61 includes a microcomputer including a CPU, various memories, and the like, and is attached to the inner wall surface of the first living room 14A, for example.

  The home server 61 is connected with a human sensor 62 as human detection means for detecting the presence of a person in the living rooms 14A to 14D and an operation device 63 such as a remote controller operated by the person. The human sensor 62 is provided in each of the living rooms 14 </ b> A to 14 </ b> D, individually detects that there is a person in the living rooms 14 </ b> A to 14 </ b> D, and outputs a detection signal to the home server 61. The operation device 63 can set a cooling operation, a heating operation, a target temperature, and the like for the air conditioning equipment, and outputs a signal corresponding to the set content to the home server 61.

  The air conditioning indoor unit 21 and each inflow fan 54 are connected to the home server 61, and the operation control of the air conditioning indoor unit 21 and each inflow fan 54 is performed by outputting a command signal. For example, when performing air conditioning on all of the living rooms 14A to 14D, the home server 61 causes the air conditioning equipment such as the air conditioning indoor unit 21 to perform the air conditioning operation and drives each inflow fan 54.

  The conditioned air blown out from the blowing portion 51 to the corridor 15 flows along the ceiling surface of the upper ceiling portion 35 with a certain flow velocity to form a laminar flow, whereby the longitudinal direction of the corridor 15 It is easy to reach to the inflow portion 53 of the first living room 14A along. In this case, since the conditioned air easily spreads over the entire folded region 36 in a plan view, it is supplied to the living rooms 14 </ b> A to 14 </ b> D from each of the inflow portions 53 as the inflow fans 54 are driven. Become. The air in the living rooms 14 </ b> A to 14 </ b> D flows out from the respective outflow portions 55 with the supply of the conditioned air and flows along the floor surface of the corridor 15 and is taken into the air-conditioned indoor unit 21 from the return air portion 52. As described above, the entire building is air-conditioned for the living rooms 14A to 14D.

  In addition, the home server 61 can perform air conditioning for a room where a person is present among the rooms 14A to 14D. The home server 61 determines the presence / absence of a person in each of the living rooms 14A to 14D based on the detection signal of the human sensor 62, and does not set a room without a person as a target for air conditioning but sets a room with a person as a target for air conditioning. Then, the air conditioning facility is caused to perform the air conditioning operation, and the inflow fan 54 in the room to be air-conditioned is driven.

  For example, when there is a person in the second living room 14B, the home server 61 rotates the inflow fan 54 of the second living room 14B to supply conditioned air from the corridor 15 to the second living room 14B. In this case, since the inflow fans 54 in the first living room 14A, the third living room 14C, and the fourth living room 14D are not rotated, it is difficult for the conditioned air to flow into the living rooms 14A, 14C, and 14D. In addition, in the second living room 14B and the fourth living room 14D, the respective inflow portions 53 are in positions facing each other across the corridor 15, but the respective outflow portions 55 are not in positions facing each other. For this reason, in the 2nd living room 14B, it controls that the air which flowed out from the outflow part 55 in connection with the inflow of the conditioned air from the inflow part 53 flows into the 4th living room 14D from the outflow part 55 of 4th living room 14D as it is. it can.

  In general, the entire building is air-conditioned, and the inflow fan 54 is driven at a low speed for all the inflow sections 53, and the driving state of the inflow fan 54 in the air-conditioned room is shifted from a low speed to a high speed. Also good. Further, in this case, the rotational speed of the inflow fan 54 in the room that is not subject to air conditioning may be further reduced from a low speed.

  When the home server 61 causes the air-conditioning indoor unit 21 to perform the heating operation, warm heating air is blown out from the blowing unit 51. In this case, since the heating air is likely to rise, the heating air flowing along the ceiling surface of the upper ceiling portion 35 becomes a laminar flow, and is less likely to be diffused downward than the lower ceiling portion 34. The ratio of the supply amount from the inflow portion 53 to the rooms 14A to 14D with respect to the blowout amount from the blowout portion 51 is increased. Therefore, in the configuration in which the area near the hallway ceiling 31 is used as the flow path for the heating air, even if the hallway ceiling 31 does not have the folded area 36, the heating efficiency of the living rooms 14A to 14D is high. It becomes possible to hold.

  On the other hand, when the home server 61 causes the air conditioning indoor unit 21 to perform the cooling operation, cold air is blown out from the blowing unit 51. In this case, since the cooling air is easy to flow down, it is considered that the cooling air flowing along the ceiling surface of the upper ceiling portion 35 is less likely to be laminar and is likely to diffuse downward from the lower ceiling portion 34. On the other hand, since the downward open side in the folded-up region 36 is narrowed by the lower ceiling 34, the lower ceiling 34 suppresses the cooling air from diffusing downward, and as a result. The ratio of the supply amount from the inflow portion 53 to the living rooms 14A to 14D with respect to the blowout amount from the blowout portion 51 is suppressed. Therefore, even when the area near the hallway ceiling 31 is used as a flow path for the cooling air, it is possible to suppress a decrease in the cooling efficiency of the living rooms 14A to 14D.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  Since the internal area of the corridor 15 is used to transport the conditioned air from the air conditioning indoor unit 21 to the living room 14, it is not necessary to install an air conditioning duct for each living room 14 in the ceiling space of the corridor 15 or the living room 14. Therefore, it is possible to avoid a narrowing of living spaces such as the hallway 15 and the living room 14 by expanding the ceiling space. In addition, since the conditioned air blown out from the blowout part 51 flows along the ceiling surface of the hallway 15 and flows into the living room 14 through the inflow part 53 as it is, the conditioned air becomes difficult to diffuse throughout the interior area of the hallway 15. Yes. For this reason, it can suppress that the air-conditioning effect by air-conditioning air is provided to the corridor 15, and the air-conditioning efficiency in the living room 14 falls. As described above, a plurality of living rooms 14 can be suitably air-conditioned without using an air conditioning duct for transporting conditioned air to the living room 14.

  Originally, the air-conditioning ducts are necessary for the living rooms 14A to 14D to transport the temperature-conditioned air, but the air-conditioning air can be transported to the living rooms 14A to 14D without using the air-conditioning duct. It is possible to reduce the influence on the constraints and the impression of appearance (compression).

  Since the conditioned air flowing along the ceiling surface of the upper ceiling portion 35 is guided by the side surface of the lower ceiling portion 34 as the guiding means, the conditioned air can easily flow into the inflow portion 53, thereby The air conditioning efficiency in the living room 14 can be increased. Moreover, in the configuration in which the conditioned air flows along the ceiling surface of the corridor 15, the guide means for guiding the conditioned air only needs to be provided in an area near the ceiling of the corridor 15. It can suppress that the lower ceiling part 34 as a guide means becomes obstructive. That is, it is possible to suppress the use of the hallway 15 from being lowered by the lower ceiling portion 34.

  Since the folded-up region 36 is formed by the lower ceiling part 34 and the upper ceiling part 35, diffusion of the conditioned air flowing along the ceiling surface of the upper ceiling part 35 can be suppressed. Further, in the hallway 15, since a person passes through a region below the lower ceiling portion 34, the laminar flow of the conditioned air in the folded-up region 36 can be prevented from being disturbed by the presence of the person. Therefore, it becomes easy for air-conditioned air to flow into the living room 14 through the inflow part 53, and as a result, it can suppress that the air-conditioning efficiency of the living room 14 falls.

  Since the blowing part 51 is disposed at a position higher than the lower ceiling part 34, the blowing part 51 can blow conditioned air directly into the folded region 36. Thereby, a configuration in which the conditioned air can easily flow along the ceiling surface of the upper ceiling portion 35 in the folded-up region 36 can be realized. Further, in this case, the angle at which the conditioned air blown from the blowing portion 51 hits the ceiling surface of the upper ceiling portion 35 is reduced as compared with the case where the blowing portion 51 is disposed at a position lower than the lower ceiling portion 34. be able to. In this case, it can be suppressed that the conditioned air hits the ceiling surface of the upper ceiling portion 35 and diffuses below the lower ceiling portion 34 with that momentum.

  Since the inflow portion 53 is arranged at a position higher than the lower ceiling portion 34, the conditioned air that has flowed through the folded-up region 36 easily flows into the living room 14 through the inflow portion 53 as it is. Moreover, since the inflow fan 54 is provided in the inflow portion 53, the amount of conditioned air flowing into the inflow portion 53 can be increased by driving the inflow fan 54.

  Since the concave portion 38 is provided between the upper ceiling portion 35 and the lower ceiling portion 34, the conditioned air flowing in the concave portion 38 in the folded region 36 is directed downward from the ceiling surface of the lower ceiling portion 34. Diffusion can be suppressed by the lower ceiling portion 34. In addition, since the conditioned air is blown out from the blowing portion 51 toward the inner region of the recess 38, the conditioned air easily flows in the recess 38. In particular, when the conditioned air is cooling air, the cooling air is likely to flow down. Therefore, suppressing the cooling air flow by the lower ceiling portion 34 is effective in increasing the cooling efficiency of the living room 14.

  In the corridor 15, indirect illumination can be constructed by installing the luminaire 25 in the recess 38. In this case, the inside of the recess 38 is not used as a dedicated area for flowing conditioned air, but is used as both a space for flowing conditioned air and a space for constructing indirect illumination.

  Since the inner peripheral surface of the recessed portion 38 in the folded-up region 36 is a plate surface formed by a plate material, the recessed portion 38 is compared with a configuration in which a ceiling base material such as a field edge is exposed inside the recessed portion 38. Air-conditioned air easily flows inside.

  In the configuration in which the blowout part 51 and the inflow part 53 are arranged near the ceiling surface of the upper ceiling part 35 of the hallway 15, the return air part 52 and the outflow part 55 are arranged near the floor surface of the hallway 15. The conditioned air blown from the section 51 is supplied to the living room 14 along the ceiling surface of the hallway 15, and the air of the living room 14 is easily taken in as return air along the floor surface of the hallway 15. Therefore, the conditioned air is easily circulated when the entire building is air-conditioned.

[Other Embodiments]
The present invention is not limited to the description of the above embodiments, and may be implemented as follows, for example.

  (1) In the above embodiment, the concave portion 38 is provided on the side surface of the lower ceiling portion 34, but the concave portion 38 may not be provided as shown in FIG. In this case, the width dimension of the hallway 15 (the separation distance of the partition walls 11 facing each other across the hallway 15) is smaller in the upper part than the lower part than the ceiling surface of the lower ceiling part 34, and the recess 38 is The folding region 36 is smaller than the provided configuration. Thereby, it is possible to prevent the conditioned air from diffusing in the horizontal direction along the ceiling surface of the upper ceiling portion 35, and as a result, the conditioned air easily flows into the inflow portion 53.

  The inflow portion 53 may be provided at a position lower than the ceiling surface of the lower ceiling portion 34. Here, the conditioned air flowing along the upper ceiling portion 35 is expected to flow down from the folded region 36, and the conditioned air that has flowed down flows along the ceiling surface of the lower ceiling portion 34. . For this reason, even if the inflow part 53 is arrange | positioned under the lower ceiling part 34, it is possible to flow conditioned air into the room 14A-14D through the inflow part 53. FIG.

  In the peripheral part of the hallway 15, there may be a non-installation part where the lower ceiling part 34 is not installed. Further, the vent hole of the outflow portion 55 may directly penetrate the partition wall 11 instead of the door 17.

  The blowing part 51 may be provided in the hallway ceiling 31. For example, the blowing part 51 is configured to be provided on the upper ceiling part 35 of the hallway ceiling 31. Even in this case, it is preferable that the blowing unit 51 blows out the conditioned air in a direction of flowing along the ceiling surface of the upper ceiling portion 35. Further, the blowing part 51 may be provided on a ceiling surface or a side surface of the lower ceiling part 34. Further, the blow-out unit 51 may be configured to blow out the conditioned air in a direction that flows along the lower ceiling portion 34. In these cases, the air conditioning indoor unit 21 may be installed in a ceiling space or a wall space.

  (2) In the above embodiment, the ceiling surface of the lower ceiling portion 34 of the hallway ceiling 31 is disposed at a position lower than the ceiling surface of the living room ceiling 41. However, the ceiling surface of the lower ceiling portion 34 is the ceiling of the living room. You may arrange | position in the same height position as the ceiling surface of 41, or a position higher than it. For example, as shown in FIG. 6, the ceiling surface of the lower ceiling portion 34 is arranged at the same height as the ceiling surface of the living room ceiling 41, and the ceiling surface of the upper ceiling portion 35 is higher than the ceiling surface of the living room ceiling 41. The configuration is arranged at a position. In this configuration, since the partition wall 11 does not extend above the ceiling surface of the lower ceiling portion 34, the inflow portion 53 penetrating the partition wall 11 is disposed at a position below the lower ceiling portion 34.

  Apart from the lower ceiling part 34, there may be provided a restricting means for restricting the flow of conditioned air flowing along the ceiling surface of the hallway ceiling 31. For example, a film-like regulation sheet 71 may be provided as a regulation means so as to be spanned across the partition wall 11 facing each other across the hallway 15. In this case, the restriction sheet 71 is disposed at a position lower than the inflow portion 53 and the blowout portion 51, and the conditioned air blown from the blowout portion 51 is an area sandwiched between the hallway ceiling 31 and the restriction sheet 71. Will flow. Accordingly, it is possible to realize a configuration in which the conditioned air easily flows into the living rooms 14A to 14D from the inflow portion 53.

  In addition, it is preferable that the regulation sheet 71 has translucency. In this case, for example, even if the lighting fixture 25 is provided at a position higher than the regulation sheet 71, light from the lighting fixture 25 can illuminate the lower side through the regulation sheet 71.

  (3) In the above embodiment, the lower ceiling portion 34 protrudes from the partition wall 11 toward the side, but the lower ceiling portion 34 may protrude downward from the upper ceiling portion 35. In this configuration, the lower ceiling portion 34 is provided at an intermediate position in the width direction of the hallway 15, and the upper ceiling portions 35 are disposed on both sides of the lower ceiling portion 34. In this case, the folded region 36 is formed between the side surface of the lower ceiling portion 34 and the partition wall 11.

  (4) The inflow fan 54 may be provided in the hallway 15 instead of the inflow portion 53. For example, the inflow fan 54 is configured to be attached to the ceiling surface of the upper ceiling portion 35 in the folded region 36. Even in this case, when the inflow fan 54 is driven, the conditioned air is forced to flow toward the inflow portion 53, and easily flows into the living rooms 14 </ b> A to 14 </ b> D through the inflow portion 53.

  (5) When the corridor 15 is branched into a plurality of lower corridors, the guiding means for guiding the conditioned air may have a distribution means for distributing the conditioned air guidance destination. For example, the corridor 15 has a first corridor lower portion 81 and a second corridor lower portion 82 branched from the first corridor lower portion 81, and the blowing portion 51 is directed toward a branch portion of the corridor lower portions 81 and 82. It is set as the structure arrange | positioned in the position which blows off conditioned air. In this configuration, the conditioned air blown from the blow-out portion 51 flows into at least one of the corridor lower portions 81 and 82 via the branch portion.

  For example, in the configuration shown in FIG. 7A, the lower ceiling portion 34 (folded region 36) extends along the corridor lower portions 81 and 82, and the switching member 83 that switches the direction in which the air-conditioned air flows is distributed. As a means, it is provided in the folded-up region 36 at the branch portion of the corridor lower parts 81 and 82. The switching member 83 is a ventilation blocking member capable of blocking the ventilation in the folded-up region 36, and restricts the flow of conditioned air into the first corridor lower portion 81 and does not restrict the flow of air into the second corridor lower portion 82. It is possible to shift to a first restricted state and a second restricted state in which the conditioned air is restricted from flowing into the second corridor lower part 82 and is not restricted from flowing into the first corridor lower part 81.

  Here, if the first corridor lower part 81 is in communication with the first living room 14A and the second corridor lower part 82 is in communication with the second living room 14B, the switching member 83 is in the first restricted state. The conditioned air blown out from the blow-out unit 51 flows into the first living room 14A through the first corridor lower part 81, thereby air-conditioning the first living room 14A. In addition, when the switching member 83 is in the second restricted state, the conditioned air flows into the second living room 14B through the second corridor lower part 82, thereby air-conditioning the second living room 14B.

  Note that the switching member 83 may be capable of shifting to a state in which the conditioned air is not restricted from flowing into either the first corridor lower part 81 or the second corridor lower part 82. In this case, since the conditioned air flows into both the first corridor lower part 81 and the second corridor lower part 82, air conditioning can be performed for both the first living room 14A and the second living room 14B. Moreover, the lower ceiling part 34 (folding area | region 36) does not need to be provided. In this case, it is only necessary that the switching member 83 can block the ventilation of the area on the ceiling surface side in the hallway 15.

  In the configuration shown in FIG. 7B, the lower ceiling portion 34 (folded region 36) is not provided, and the blower fan 84 configured to include an electric motor is provided in the first corridor lower portion 81 and the second corridor lower portion. 82 is provided for each. In this case, the conditioned air flows into the lower corridor where the blower fan 84 is driven, and selecting the blower fan 84 to be driven distributes the conditioned air to the lower corridors 81 and 82 (rooms for air conditioning). It will be. The blower fan 84 is included in the guide means.

  An accelerating member 85 that facilitates the flow of conditioned air into the first corridor lower portion 81 side and the second corridor lower portion 82 side may be provided at a branch portion between the first corridor lower portion 81 and the second corridor lower portion 82. The accelerating member 85 is attached to the wall surface of the partition wall 11 that faces the blowing portion 51 at the branching portion, and is tapered toward the blowing portion 51 along the boundary portion between the first corridor lower portion 81 and the second corridor lower portion 82. It protrudes in a shape. The taper surface of the promotion member 85 is curved so as to be recessed, and the conditioned air that has flowed from the blowout part 51 toward the promotion member 85 passes along the first corridor lower portion 81 or the taper surface that is the side surface of the promotion member 85. Guided to the second corridor lower part 82. The promotion member 85 is included in the guide means.

  The promotion member 85 is attached to both the ceiling surface and the wall surface of the hallway 15 and is disposed in a region near the ceiling surface. Thereby, it can avoid that the promotion member 85 becomes the obstruction of a person's walk in the hallway 15. Further, in the configuration in which the folded region 36 is formed in the hallway 15 as shown in FIG. 7A, the promoting member 85 is preferably provided in the folded region 36. In this case, the conditioned air flowing in the folded region 36 along the ceiling surface of the upper ceiling portion 35 is guided to the first corridor lower portion 81 and the second corridor lower portion 82 by the promotion member 85.

  Further, the promotion member 85 may be attached to the outer wall surface of the curved portion (the corner portion of the partition wall 11) in the corridor 15 having the curved portion bent at a right angle in the horizontal direction. In this case, the taper surface of the promoting member 85 is in a state where the corner portion outside the bent portion is chamfered, and the conditioned air easily flows along the taper surface of the promoting member 85.

  (6) The recess 38 provided on the side surface of the lower ceiling portion 34 may be disposed at a position spaced downward from the ceiling surface of the upper ceiling portion 35. Even in this case, the conditioned air blown out into the concave portion 38 flows along the ceiling surface of the upper ceiling portion 35 by flowing out from the concave portion 38 to the side. Further, the lighting fixture 25 may not be installed in the recess 38.

  (7) In the above embodiment, the blowout part 51 is provided at a position where the conditioned air is blown out so as to flow along the ceiling surface of the hallway ceiling 31, but the conditioned air flows along the floor surface of the hallway 15. It may be provided at a position to blow out. For example, it is set as the structure by which the blowing part 51 is provided in the floor surface vicinity in the partition wall 11, or a floor part. In this configuration, in the same manner as the blowout part 51, the inflow part 53 is provided near the floor surface of the partition wall 11 or on the floor part, and the return air part 52 and the outflow part 55 are near the ceiling surface of the partition wall 11, or It is provided in the hallway ceiling 31. In this case, the cooling air is blown out from the blow-out part 51, so that the cooling air flows along the floor surface of the corridor 15 and flows into the living rooms 14 </ b> A to 14 </ b> D from the inflow part 53. Cooling is performed. Similarly, the heating of the living rooms 14 </ b> A to 14 </ b> D is performed by blowing the heating air from the blowing unit 51.

  Further, in the air conditioning indoor unit 21, the air conditioning fan can rotate in the reverse direction, and the air conditioning fan rotates in the reverse direction so that the conditioned air is blown out through the return air unit 52 and the return air is taken in from the corridor 15 through the blowout unit 51. It is good. In this configuration, in the living rooms 14A to 14D, the inflow fan 54 is provided not only in the inflow portion 53 but also in the outflow portion 55, and when the air-conditioning fan is reversely rotated, the inflow fan 54 of the outflow portion 55 is The air-conditioning air that has flowed along the floor surface of the corridor 15 is rotated in a direction to flow into the living rooms 14A to 14D.

  (8) The configuration in which the conditioned air blown from the blowing unit 51 flows along the ceiling surface of the hallway ceiling 31 may not be applied to the entire building air conditioning system. For example, only one living room 14 may be air-conditioned, and conditioned air for that purpose may be supplied from the corridor 15 to the living room 14 through the inflow portion 53.
