Furthermore, an opening facing the interior of the building is formed on the front surface of the first heat exchanger 521, and this opening constitutes an indoor suction portion 521d. To the second heat exchanger 522, an outside air intake pipe 522a, an exhaust pipe 522b, and an indoor air supply pipe 522c are connected. Further, an opening facing the indoor side of the building is formed on the front surface of the second heat exchanger 522, and this opening constitutes an indoor suction portion 522d. The outside air intake pipes 521a and 522a, the exhaust pipes 521b and 522b, and the indoor air supply pipes 521c and 522c located in the air conditioning equipment space 501 are housed in the second air conditioning equipment space 501b.

  The outside air suction pipes 521a and 522a are pipes through which the first heat exchanger 521 and the second heat exchanger 522 suck outside air for heat exchange, respectively. The outside air for heat exchange exchanges heat with the air in the building in the first heat exchanger 521 and the second heat exchanger 522. The outside air intake pipes 521a and 522a respectively extend upward from the first heat exchanger 521 and the second heat exchanger 522, extend outside the air conditioner space 501 and open outside the fourth unit 400, that is, outside. . The outside air suction pipes 521a and 522a pass through the upper part in the fourth unit 400 and open at the wall 405a.

  The exhaust pipes 521b and 522b are pipes for the first heat exchanger 521 and the second heat exchanger 522 to discharge air after heat exchange, respectively. The air after heat exchange is air in the building after heat exchange with outside air for heat exchange in the first heat exchanger 521 and the second heat exchanger 522. The exhaust pipes 521b and 522b respectively extend upward from the first heat exchanger 521 and the second heat exchanger 522, extend outside the air conditioning equipment space 501, and open to the outside of the fourth unit 400, that is, outdoors. The exhaust pipes 521b and 522b pass through the upper part in the fourth unit 400 and are opened at the wall 405a.

  The indoor air supply pipes 521c and 522c are pipes for the first heat exchanger 521 and the second heat exchanger 522 to supply the outside air after heat exchange into the building, respectively. The indoor air supply pipes 521c and 522c extend downward from the first heat exchanger 521 and the second heat exchanger 522, respectively, and are further blown out parts 550 disposed in the vicinity of the connecting portion of the third unit 300 and the fourth unit 400. It opens toward the indoors in a substantially horizontal direction. The indoor air supply pipes 521c and 522c extend substantially horizontally toward the direction away from the units 300 and 400, that is, indoors, and protrude from the units 300 and 400 at the outlet 550. The indoor air supply pipes 521c and 522c are disposed on both sides in the horizontal direction of the cooling / heating outlets 551 of the cooling / heating machines 511 and 512, which will be described later, and protrude beyond the cooling / heating outlets 551. In the present embodiment, the blowing unit 550 is assembled to the fourth unit 400 when the fourth unit 400 is manufactured, and is connected to the indoor air supply pipes 521c and 522c and the like. Here, the blowout part 550 is an example of a blower outlet, and the air-conditioning blower 551 is an example of an air-conditioning blower outlet.

  The indoor suction portions 521d and 522d are openings through which the first heat exchanger 521 and the second heat exchanger 522 suck air in the building, respectively. Specifically, the indoor suction section 521d is connected to a suction pipe (not shown) arranged on the first floor of the building, and the first heat exchanger 521 is connected to the first floor air in the building via the indoor suction section 521d. , And exchanges heat between the inhaled air and the outside air. The indoor suction portion 522d is connected to a suction pipe (not shown) disposed on the second floor of the building, and the second heat exchanger 522 sucks and sucks air on the second floor in the building via the indoor suction portion 522d. Heat is exchanged between the heated air and the outside air.

  The first heat exchanger 521 as described above exchanges heat between the air on the first floor in the building and the outside air, discharges the air on the first floor after the heat exchange to the outside of the building, and blows out the outside air after the heat exchange. Air is supplied into the building through the section 550. In addition, the second heat exchanger 522 exchanges heat between the air on the second floor in the building and the outside air, discharges the air on the second floor after the heat exchange to the outdoors, and passes the outside air after the heat exchange through the blowout unit 550. Then air indoors.

  20 and FIG. 21, the first air conditioner 511 of the air conditioners 511 and 512 is disposed below the blowout part 550, and the second air conditioner 512 is located above the blowout part 550. Is arranged. Two air conditioning / heating supply pipes 511 a extending from the first air conditioning / heating device 511 are connected to the lower part of the air conditioning / heating outlet 551 of the outlet 550. Two cooling / heating supply pipes 512 a extending from the second cooling / heating machine 512 are connected to the upper part of the cooling / heating outlet 551. The 1st air conditioning machine 511 and the 2nd air conditioning machine 512 send the air after air conditioning to the indoor of a building through the air conditioning blowing part 551. Further, the first air conditioner 511 and the second air conditioner 512 are connected to the first outdoor unit 513 shown in FIG. 7 via a pipe (not shown).

  The blow-out unit 550 includes outlets of the indoor air supply pipes 521c and 522c of the first heat exchanger 521 and the second heat exchanger 522, and air-conditioning / heating air supply pipes 511a and 512a of the first air-conditioner 511 and the second air-conditioner 512, respectively. Including the outlets. The blowing unit 550 has a cooling / heating blowing unit 551 at the center in the horizontal direction. The air conditioning / heating outlet 551 is a chamber opened in a substantially horizontal direction. The air conditioning / heating outlet 551 is divided into upper and lower parts by directing plates 551a and 551b to form two chambers. The directivity plate 551a that forms a curve from the upper side toward the horizontal side is substantially horizontal toward the indoors of the building. Air conditioning air that is sent upward from the cooling / heating air supply pipe 511a into the lower chamber of the blow-out unit 550. Oriented in the direction. A directing plate 551b that forms a curve from the lower side toward the horizontal side is a substantially horizontal direction in which the cooling / heating air that is sent downward from the cooling / heating air supply pipe 512a into the upper chamber of the blow-out portion 550 is directed to the interior of the building. Oriented to.

  Indoor air supply pipes 521c and 522c extending substantially in the horizontal direction are positioned on both sides in the horizontal direction of the cooling / heating outlet 551, respectively. The blowing unit 550 includes a partition wall 551c that separates the cooling / heating blowing unit 551 and the indoor supply pipe 521c, and a partition wall 551d that separates the cooling / heating blowing unit 551 and the indoor supply pipe 522c. The partition walls 551c and 551d extend substantially vertically, and prevent the cooling / heating air sent from the cooling / heating supply pipes 511a and 512a to the cooling / heating outlet 551 from diffusing toward the indoor supply pipes 521c and 522c. In addition, between the partition walls 551c and 551d, the directional plates 551a and 551b and the openings of the air conditioning / heating supply pipes 511a and 512a are arranged. The substantially horizontal openings of the indoor air supply pipes 521c and 522c are shifted from the substantially horizontal opening of the cooling / heating outlet 551 in a substantially horizontal direction, which is a direction away from the units 300 and 400, specifically, It is in a position farther from the units 300 and 400 than the opening of the outlet 551. There may be a large difference between the temperature of the cooling / heating air flowing through the cooling / heating outlet 551 and the temperature of the outside air after heat exchange flowing through the indoor air supply pipes 521c and 522c. Since the opening of the air-conditioning / air-blowing section 551 and the openings of the indoor air supply pipes 521c and 522c are separated from each other, the occurrence of dew condensation due to the contact between the air-conditioning air and the outside air after heat exchange is suppressed. Further, the partition walls 551c and 551d can also prevent contact between the cooling / heating air and the outside air after heat exchange.

  Referring to FIG. 22, the relationship between the blowing part 550 and the building A in which the units 100 to 400 are arranged is shown. FIG. 22 is a schematic diagram showing the air conditioning configuration of the building A. As shown in FIG. 22, the building A has a ceiling pocket B on the ceiling of the first floor between the first floor and the second floor. The ceiling pocket B is surrounded by the floor, ceiling, wall, and the like of the building A to form a closed space, that is, a chamber. The ceiling pocket B communicates with the first-floor space and the second-floor space of the building A through a plurality of air holes formed in the first-floor ceiling and the second-floor floor of the building A, respectively. Furthermore, the blowing part 550 communicates with the ceiling pocket B. Specifically, the indoor air supply pipes 521c and 522c of the blowing unit 550 are opened in the ceiling pocket B, and the cooling / heating blowing unit 551 is opened in the ceiling pocket B.

  Thereby, the outside air after the heat exchange in the first heat exchanger 521 and the second heat exchanger 522, and the air-conditioning air by the first air-conditioner 511 and the second air-conditioner 512 are sent out into the ceiling pocket B, It is emitted from the ceiling pocket B into the first floor space and the second floor space of the building A. A part of the air in the first floor space of the building A is inhaled by the first heat exchanger 521 through the indoor suction part 521d, is then heat-exchanged with the outside air, and is discharged outside the building A. The other part of the air in the first floor space of the building A is sucked by the first air conditioner 511 and is subjected to the air conditioning process. A part of the air in the second floor space of the building A is inhaled by the second heat exchanger 522 through the indoor suction part 522d, is then heat-exchanged with the outside air, and is discharged outside the building A. The other part of the air in the second floor space of the building A is sucked by the second air conditioner 512 and is subjected to the air conditioning process. In this way, air conditioning control of the entire building A is possible using the chambered ceiling pocket B and the outlet 550.

  Moreover, the 1st air conditioning machine 511 is provided with the 1st temperature sensor 511b which detects the temperature in the space of the 1st floor of the building A, and the 2nd air conditioning machine 512 detects the temperature in the space of the 2nd floor of the building A. A second temperature sensor 512b may be provided. At this time, the first air conditioner 511 may control the temperature of the air conditioning air based on the temperature detected by the first temperature sensor 511b, and the second air conditioner 512 may be controlled based on the temperature detected by the second temperature sensor 512b. The temperature of the air may be controlled. For example, the first temperature sensor 511b may detect the temperature near the ceiling on the first floor, and the second temperature sensor 512b may detect the temperature near the floor on the second floor. For example, when heating the building A, the second floor is warmer than the first floor, and the vicinity of the ceiling is warmer than the vicinity of the floor on each floor. For this reason, the vicinity of the ceiling on the second floor is the hottest, and the vicinity of the floor on the first floor is the coldest. Since the first temperature sensor 511b and the second temperature sensor 512b are arranged as described above, the detected temperatures of the first temperature sensor 511b and the second temperature sensor 512b are relatively close to each other. And the 2nd air conditioning machine 512 can maintain the whole building A at a suitable temperature. On the other hand, when the two temperature sensors detect the temperature near the ceiling on the second floor and the temperature near the floor on the first floor, the temperature of the entire building A is too low in the first air conditioner 511 and the second air conditioner 512. Or there is a possibility of air conditioning control that becomes too high.

  Furthermore, with reference to FIGS. 17-19 and FIGS. 23-25, the structure of the heat pump type water heater 530 and its periphery is demonstrated. FIG. 23 is a schematic perspective view showing the configuration of the water heater space 532 in which the heat pump type water heater 530 is arranged. FIG. 24 is a perspective view of the water heater space 532 of FIG. 23 as viewed from the back. FIG. 25 is a schematic perspective view showing the lower opening 533ba of the circulation facility 533 of FIG. 23 and the periphery thereof in an enlarged manner.

  In particular, as shown in FIG. 23, the third unit 300 forms a water heater space 532 in which the heat pump hot water heater 530 is disposed below the first air conditioner 511 in the first air conditioning equipment space 501a. . In the present embodiment, the water heater space 532 is located on the floor surface of the third unit 300. The periphery of the water heater space 532 is covered with a heat insulating wall 532a except for the surface covered with the interior panel 307 (see FIG. 1). The heat insulating wall 532a may be configured by a plate-shaped heat insulating material, or may be configured by a plate-shaped member to which the heat insulating material is attached. Such a water heater space 532 forms a heat insulating space. Further, a vent hole 532ab is formed through the first heat insulating wall 532aa which is a portion facing the interior panel 307 of the heat insulating wall 532a. The vent hole 532ab is disposed at the upper part of the first heat insulating wall 532aa. As shown in FIG. 24, the first duct 533a of the circulation facility 533 disposed outside the heat insulating wall 532a is connected to the vent hole 532ab. The heat generated by the heat pump type water heater 530 disposed in the water heater space 532 is suppressed from being diffused to the surroundings by the heat insulating wall 532a and flows out from the vent hole 532ab into the first duct 533a.

  As shown in FIGS. 17, 19, and 24, the circulation facility 533 includes a second duct 533b and a blower 533c disposed in the second duct 533b in addition to the first duct 533a. The second duct 533b extends vertically through the first air conditioner space 501a and the second air conditioner space 501b, and is open at both ends. The second duct 533b has a lower opening 533ba having a diverging shape in the lower part of the first air conditioning equipment space 501a, specifically, in the vicinity of the floor of the third unit 300 and the base 301, and the second air conditioning equipment space 501b. A cylindrical upper opening 533bb is provided near the top of the fourth unit 400, specifically, near the ceiling of the fourth unit 400. The shapes of the lower opening 533ba and the upper opening 533bb are not limited to the above shapes.

  As shown in FIG.23 and FIG.25, lower opening part 533ba is located adjacent to the heat insulation wall 532a of the water heater space 532 on the outside, and opens toward the inside of the building. For this reason, the air flowing through the second duct 533b can be discharged to the vicinity of the floor surface of the first floor of the building through the lower opening 533ba. Alternatively, air near the floor of the first floor of the building can be sucked into the second duct 533b through the lower opening 533ba.

  As shown in FIGS. 17 to 20, the upper opening 533 bb opens toward the inside of the building, similarly to the lower opening 533 ba. The air flowing in the second duct 533b can be discharged to the vicinity of the ceiling on the second floor of the building through the upper opening 533bb. Alternatively, air near the ceiling of the second floor of the building can be sucked into the second duct 533b through the upper opening 533bb.

  The first duct 533a extends upward from the vent hole 532ab, is connected to the second duct 533b, and communicates with the second duct 533b in the second air conditioning equipment space 501b. The blower 533c is disposed in the second duct 533b between the connection portion of the first duct 533a and the second duct 533b and the lower opening 533ba. In this Embodiment, the air blower 533c is an electric fan, and is arrange | positioned in the 2nd air conditioning equipment space 501b. In the present embodiment, the blower 533c forms an air flow from the upper opening 533bb toward the lower opening 533ba in the second duct 533b. However, the present invention is not limited to this, and the blower 533c may be configured to form an air flow from the lower opening 533ba toward the upper opening 533bb. Note that the position of the blower 533c is not limited to the above position, and any position as long as the blower 533c can form an air flow between the upper opening 533bb and the lower opening 533ba in the second duct 533b. There may be. Further, the position of the connecting portion between the first duct 533a and the second duct 533b may be any position in the second duct 533b.

  In the circulation facility 533 configured as described above, for example, the blower 533c forms an air flow from the upper opening 533bb toward the lower opening 533ba in the second duct 533b. In this case, the air on the second floor of the building is sucked into the second duct 533b from the upper opening 533bb, and the air including the exhaust heat of the heat pump water heater 530 in the water heater space 532 passes through the first duct 533a. And sucked into the second duct 533b. The air on the second floor of the building and the air containing exhaust heat are mixed in the second duct 533b and sent out indoors through the lower opening 533ba. Thereby, relatively warm air including the heat of the air on the second floor of the building and the exhaust heat of the heat pump water heater 530 is supplied to the vicinity of the floor surface of the first floor of the building. Therefore, heating using the exhaust heat of the heat pump hot water heater 530 and the heat of the air accumulated on the ceiling of the second floor of the building is possible.

  Further, for example, as shown in FIG. 26, the position of the lower opening 533ba of the second duct 533b of the circulation facility 533, the positions of the air conditioning and heating air supply pipes 511a and 512a of the air conditioning units 511 and 512, and the heat exchanger 521 And the opening positions of the indoor air supply pipes 521c and 522c of 522 may be changed. FIG. 26 is a perspective view showing another example of the indoor air supply position by the circulation facility 533, the air conditioners 511 and 512, and the heat exchangers 521 and 522. The second duct 533 b of the circulation facility 533 has an upper opening 533 bb near the ceiling of the fourth unit 400 and a lower opening 533 ba on the back of the staircase 600. Specifically, the lower opening 533ba is opened toward the step board 600. The raised plate of the staircase 600 is configured to allow air to pass therethrough. For example, a plurality of holes such as a plurality of slits and a plurality of ventilation holes are formed in the kneading plate of the staircase 600, or the kneading plate has a grill shape, a mesh shape, or the like. For this reason, the air supply from lower opening part 533ba passes through a squeezing board, and is supplied indoors of a building. Although it does not limit, in this example, lower opening part 533ba is located in the 1st floor of a building, and is specifically located in the vicinity of the floor surface of the 3rd unit 300. FIG.

  Moreover, the air-conditioning / heating supply pipe 511a of the first air-conditioning / heating machine 511 is opened at the back of the staircase 600 in the same manner as the lower opening 533ba of the second duct 533b. Although it does not limit, in this example, the air-conditioning / heating supply pipe 511a is opened near the floor surface of the third unit 300. Air-conditioning air sent out from the air-conditioning / air-supply pipe 511a passes through the escape plate and is supplied to the first floor of the building. The cooling / heating supply pipe 512a of the second cooling / heating machine 512 opens near the ceiling of the fourth unit 400, and supplies the cooling / heating air indoors on the second floor of the building. The indoor air supply pipe 521c of the first heat exchanger 521 opens at the same position as the blow-out section 550 shown in FIG. 21, and supplies the outdoor air after heat exchange to the first floor indoors of the building. The indoor air supply pipe 522c of the second heat exchanger 522 opens near the ceiling of the fourth unit 400, and supplies the outdoor air after the heat exchange to the second floor indoors of the building. In addition, although the piping and duct for supplying air to the indoor of a building were arrange | positioned in the back part of the staircase 600, it is not limited to this, The piping and duct for inhaling from the indoor of a building may be arrange | positioned. .

[2. Effect etc.]
In embodiment, the building of a 1st aspect contains the building unit 1 which comprises the housing of a building, and is manufactured except the construction place of a building, and the site building part constructed | assembled at a construction place. The building unit 1 includes a staircase air conditioning unit 2000 as a staircase unit that includes a staircase 600 and forms at least two levels of the building, and a water unit 1000 that includes a water supply facility and forms at least two levels of the building. The staircase air conditioning unit 2000 and the water unit 1000 are arranged adjacent to each other.

  In the above configuration, the “staircase” and “water circulation equipment” necessary for a two-story building or more are combined into one package, making it possible to use the remaining space in the building widely. The free design area can be widened. Further, by concentrating the water supply facilities in the water supply unit 1000, it becomes easy to collect and store the water supply / drainage pipes in a compact manner, and maintenance of the water supply / drainage pipes becomes easy. Furthermore, for example, if electrical equipment such as air conditioning equipment and electrical equipment is disposed in the staircase air conditioning unit 2000, the electrical equipment and its wiring can be accommodated so as not to be affected by moisture due to a water supply / drainage pipe or the like. . Such a unit can cope with various arrangement plans of “staircase” and “water supply equipment”. Further, when the “stairs” and “watering equipment” are combined into one unit, the unit becomes large, and a unit manufactured in a place other than the construction site cannot be transported to the construction site. In addition, since the construction of stairs and water facilities is complex with many man-hours, increasing the number of workers does not have a significant effect on shortening the construction period and requires a construction period. The construction period can be shortened by constructing the building unit 1 in a state where these constructions have been completed in advance so as to be carried into the construction site and installed.

  In the building of the first aspect, the water facility of the water unit 1000 includes at least one of the bathroom 13, the wash basin 12, the toilet 11, and the kitchen 15. In the above configuration, the construction of the water facility as described above has a particularly large number of steps and is complicated, so that it is particularly preferable to incorporate it in the water unit 1000 in advance from the viewpoint of construction period and construction accuracy.

  In the building of the first aspect, the walls 305a and 405a of the staircase air conditioning unit 2000 and the walls 105a and 205a of the water circulation unit 1000 constitute an outer wall of the building. The staircase air conditioning unit 2000 has openings 311, 312, 412, and 413 at portions opposite to the walls 305 a and 405 a constituting the outer wall of the building. The water unit 1000 has openings 111 and 212 at portions opposite to the walls 105a and 205a constituting the outer wall of the building. In the above configuration, it is easy for a person to enter the water unit 1000 and the staircase air conditioning unit 2000 from inside the building. Since the water unit 1000 and the staircase air conditioning unit 2000 constitute the outer wall of the building, they can be arranged together on the periphery of the building. Thereby, the freedom degree of the utilization of the remaining space in a building improves.

  In the building of the first aspect, the staircase air conditioning unit 2000 includes a third unit 300 and a fourth unit 400 as a plurality of divided staircase units that can be separated and connected to each other, and the third unit 300 and the fourth unit 400 include The third unit 300 and the fourth unit 400 each form a layer. The water unit 1000 includes a first unit 100 and a second unit 200 as a plurality of divided water units that can be separated and connected to each other, and the first unit 100 and the second unit 200 are stacked on each other. The first unit 100 and the second unit 200 are connected to each other to form one layer.

  In the above configuration, when transporting from the manufacturing site to the construction site, the water circulation unit 1000 and the staircase air conditioning unit 2000 can each be transported in a compact state. As a result, the water unit 1000 and the staircase air conditioning unit 2000 can be transported by truck using a general road. Since each divided unit forms one layer, it is easy to design, manufacture, and assemble and connect at the construction site.

  In the building of the first aspect, the staircase air conditioning unit 2000 includes an opening 411 as a first opening that opens in a first direction from the staircase air conditioning unit 2000 toward the water cycle unit 1000, and It has the opening part 412 as a 2nd opening part which opens indoors and in a 2nd direction different from a 1st direction in the same hierarchy. For example, the openings 411 and 412 of the stair air conditioning unit 2000 may be adjacent to each other with the corners of the stair air conditioning unit 2000 interposed therebetween.

  In the above configuration, for example, when there is an opening in the wall adjacent to the staircase air conditioning unit 2000 in the water circulation unit 1000, people can enter and exit between the water circulation unit 1000 and the staircase air conditioning unit 2000 using the opening 411. . When there is no opening in the wall adjacent to the staircase air conditioning unit 2000 in the water turning unit 1000, people can enter and exit between the watering unit 1000 and the staircase air conditioning unit 2000 using the opening 412. For example, corresponding to various arrangement plans of the water facility and opening of the water unit 1000 such that the arrangement of the first layer and the arrangement of the second layer are switched, the passage between the water unit 1000 and the staircase air conditioning unit 2000 is changed. It can be secured. Further, when the openings 411 and 412 are adjacent to each other across the corner portion of the staircase air conditioning unit 2000, the openings 411 and 412 are located close to each other, so that the water unit 1000 corresponding to the arrangement plan of the water unit 1000 is provided. And the change of the passage between staircase air-conditioning units 2000 is suppressed small.

  In the building of the first aspect, the staircase air conditioning unit 2000 includes a distribution board 701 and wiring extending from the distribution board 701 to the water unit 1000 in a space below the stairs 600. For example, the distribution board 701 of the staircase air conditioning unit 2000 may be disposed at a position biased toward the water unit 1000 in the space below the staircase 600.
