  Hereinafter, based on FIGS. 1-27, the whole building air conditioning system 100, 200, 300, 400 which is embodiment of this invention is demonstrated.

  First, the entire building air conditioning system 100 will be described based on FIGS. 1 to 15. 1 and 2 show a schematic configuration of the whole building air conditioning system 100 according to the embodiment of the present invention, and FIGS. 3 to 5 show an actual building H1 provided with the whole building air conditioning system 100. There is a part which attaches the same numerals about a member which has a common structure or a common function. Further, in FIGS. 3 and 4, the meshed areas represent lower ceilings 11 c and 12 c.

  Generally, since the temperature setting of the air conditioning system of the building is determined by the room temperature of the room where the air conditioner exists, when installing the air conditioner in each room, the setting of the room where the air conditioner is installed before the entire building is air conditioned. As a result of the temperature being reached, the temperature of the entire building does not reach an appropriate temperature, and so-called air conditioning becomes less effective. So, in the whole building air conditioning system 100 of this embodiment, one air conditioner 10, 20 is each arrange | positioned to the common parts 11 and 12 of each floor.

  Specifically, in the case of the entire building air conditioning system 100, a priority is given to a plurality of areas provided in the building H1 with the area assumed to have a short residence time of the resident as the top, and the priority is the top Select the shared areas 11 and 12 as a certain area, and air-condition in the ceiling space 11a and 12a above the lower ceilings 11c and 12c formed lower than the ceiling surface of the shared areas 11 and 12 (other than the room) The machines 10 and 20 are arranged.

  As described above, when a priority is given to a plurality of areas in the building H1 where the area where the resident's stay time is expected to be short is set high, the shared part is selected as the high priority area 11 and 12, but in other words, the common parts 11 and 12 are human beings from this area to another area (at least a part divided by a wall and having an entrance to the other area). Is also an area that can be moved directly. That is, as shown in FIG. 3, the common part 11 is an area having the largest number of entrances to other areas in the first floor part in the building H1, and as shown in FIG. It is an area having the largest number of entrances to other areas in the floor area.

  As shown in FIGS. 1 and 2, the entire building air conditioning system 100 according to the present embodiment includes the air conditioners 10 disposed on the lower ceilings 11c and 12c of the shared portions 11 and 12 of the first and second floors of the building H1, respectively. 20, a ventilating device 30 disposed in the underfloor space 13 of the building H1, and rooms R11 and R12 which are rooms in the building H1 to supply the conditioned air supplied from the air conditioners 10 and 20 into the building H1. , R21 and R22, and the first floor in the building H1 to discharge the air in the building H1 via the line-shaped outlets 14, 14, 14, 14 which are air supply openings respectively provided in the H. And the exhaust ports 15, 15 and 15 provided on the floor surface F11 of the common part 11. An outdoor unit 21 is disposed outside the building H1. In addition, a storage room 29 and an intermediate duct fan 41 are provided in the shed space 40 above the second floor portion of the building H1.

  In the case of the whole building air conditioning system 100, contrary to the above-described priority, a priority is given to a plurality of areas in the building H1 in which the area where the resident stay time is assumed to be long is high. The outlets 14 are disposed in the rooms R11, R12, R21 and R22 which are areas selected in order from the upper area. Specifically, a priority coefficient is set according to the residence time, use priority, and area of residents of a plurality of areas (including a living room and a common part which is a non-living room) in the building H1, and the priority coefficient The air outlets 14 are arranged preferentially by selecting in order from the area (high order) where is large.

  Also, as shown in FIG. 3, the LDK is calculated based on the result of calculating the required air volume from the relationship between the priority for the area where the resident's stay time is considered to be long as the top and the size (volume) of the area. The two outlets 14 and 14 and the branch outlet 14s are installed, and the entrance outlet 47 is installed with the branch outlet 14s.

  Three ducts 23, 23 and 23 are connected to the air conditioner 10, and the downstream side of the two ducts 23 and 23 among them is connected to the blowout ports 14 and 14, respectively, and the remaining one duct 23 The downstream side is divided into two branch ducts 23s and 23s, and the downstream side of the branch ducts 23s and 23s is connected to the branch outlets 14s and 14s, respectively. The air outlet 14 and the branch air outlet 14s have the same size, structure and function.

  As shown in FIGS. 4 and 5, three ducts 23, 23 and 23 are connected to the air conditioner 20, and the downstream sides of the two ducts 23 and 23 among them are installed in the rooms R21 and R22, respectively. It is connected to the air outlet 14,14. The downstream side of the remaining one duct 23 is divided into two branch ducts 23s, 23s, and the downstream side of one branch duct 23s is connected to the branch outlet 14s of the room R23, and the downstream side of the other branch duct 23s Is connected to the branch outlet 14t of the storage room 29.

  Since the air volume of the branched duct 23s divided into two from the duct 23 becomes half of the air volume of the original duct 23, it is possible to preferentially air-condition the part where the resident stay time is long, while It becomes possible to suppress the supply of the conditioned air to the portion where the stay is expected to be short, and it is effective in improving the efficiency of the air conditioning and reducing the energy of the air conditioning. In addition, the size (volume) of the area is small, and it is possible to supply appropriate conditioned air to the portion where the air conditioning load is low, and it is possible to make the temperature distribution in the building H1 uniform.

  Moreover, according to the size of the area to be air-conditioned by selectively installing the outlet 14 connected to the duct 23 and the branch outlets 14s and 14t connected to the branch duct 23s based on the priority coefficient. The air volume can be set for each area, and the air conditioning inside the building H1 can be performed uniformly, so that the air conditioning efficiency is improved, the sensation of the occupant is improved, and the air conditioning energy can be reduced.

  The ventilation device 30 has a function of discharging the air in the building H1 sucked from the duct 16 via the underfloor space 13 to the outside of the building H1 via the duct 17, and the outside of the building H1 taken in via the duct 18. And the function of feeding air (outside air) to the air conditioners 10 and 20 via the air supply ducts 19a and 19b, respectively. In the middle of the duct 18, a filter box 44 incorporating a filter, which is an outside air cleaning means for cleaning outside air taken into the ventilation device 30, is disposed.

  In the whole building air conditioning system 100, the outlets 14 for supplying the conditioned air from the air conditioners 10 and 20 to the rooms R11, R12, R21 and R22 in the building H1 are provided. The air in the rooms R11 and R12 on the first floor flows into the airtight finished floor space 13 via the exhaust ports 15 and 15 provided on the floor surfaces F1 and F1 of the rooms R11 and R12, respectively. , It is inhaled by the duct 16 of the ventilator 30, and is exhausted out of the building H1.

  In addition, the air in the rooms R11 and R12 on the first floor flows out to the common part 11 via the undercut U provided at the lower edge of the door D which is an entrance to the rooms R11 and R12, respectively, and shared It flows into the underfloor space 13 via the exhaust port 15 provided on the floor surface F1 of the portion 11 and is exhausted by the ventilation device 30.

  Furthermore, the air in the rooms R21 and R22 on the second floor flows out to the common part 12 via the undercut U provided at the lower edge of the door D which is an entrance to the rooms R21 and R22, respectively, and shared The fluid flows from the part 12 to the common part 11 on the first floor, flows into the underfloor space 13 via the exhaust port 15 of the floor surface F1 of the common part 11, and is exhausted by the ventilation device 30.

  The air supply ducts 19a and 19b of the ventilation device 30 are connected to the air conditioners 10 and 20, and supply the air to the air conditioners 10 and 20, respectively. The ventilation device 30 is installed in the underfloor space 13 on the first floor, and exhaust air from the room is taken into the underfloor space 13 via the exhaust port 15 installed on the first floor floor F1, and the underfloor space 13 is ductless Use as a route.

  Thus, by installing the ventilating device 30 in the underfloor space 13, it becomes difficult for the operating noise of the ventilating device 30 to be transmitted to the room, so that the indoor space (inside of the rooms R11, R12, R21, R22 and the shared portions 11, 12 ) Can be kept quiet. Further, since the ventilating device 30 is disposed utilizing the underfloor space 13, there is no need to provide an installation space dedicated to the ventilating device 30, and no separate construction work is necessary.

  By using the underfloor space 13 as an exhaust path, ventilation of the underfloor space 13 can be simultaneously performed while performing air conditioning of the entire building H1. In addition, since the underfloor space 13 becomes substantially similar to the living space (inside of the rooms R11, R12, R21, and R22) by passing the air-conditioned exhaust gas through the underfloor space 13, the air conditioning load can be reduced. It is possible to suppress the deterioration of the building due to humidity and the like. Furthermore, since the installation environment of the ventilating device 30 is also improved, the product life of the ventilating device 30 itself is not impaired.

  As shown in FIG. 1, the inspection port 45 formed on the floor surface F1 of the room R11 can be used as an inspection port of the ventilation device 30. In addition, when installing the whole building air conditioning system 100 in heavy snow areas, install ventilation device 30 between the floors of the first floor and the second floor of building H1 so as not to be affected by snowfall, and install vent caps (ducts 17, 18). The caps 17a, 18a) can also be mounted at heights. When the ventilating device 30 is installed in the underfloor space 13 of the kitchen K (see FIG. 3) in the building H1, the opening 46 (see FIG. 3) of the underfloor storage can be used as an inspection port.

  In the whole building air conditioning system 100, the ventilation device 30 disposed in the underfloor space 13 is a total heat exchanger, and the air (exhaust) in the building H1 sucked through the underfloor space 13 and the air taken in from outside the building H1. It has a function to exchange heat with (outside air).

  By using the ventilation device 30, it is possible to introduce the air drawn in from outside the building H1 via the duct 18 into the building H1 in a state close to the room temperature (air conditioning temperature) in the building H1. It is effective to improve the air conditioning efficiency.

  Further, in the whole building air conditioning system 100, the air conditioners 10 and 20 are disposed in the under-the-sky spaces 11a and 12a above the lower ceilings 11c and 12c formed in the shared portions 11 and 12 in the building H, respectively. , R12, R21, R22, and R23, the air outlet 14 and the branch air outlet 14s are provided in the portion located at the shortest distance from the air conditioners 10 and 20 of each floor, respectively. Specifically, the air outlet 14 and the branch air outlet 14s are provided in the upper part of the wall surface W on the corridor 22 side or in the upper part of the wall W on the corridor 22 side of each room R11, R12, R21, R22.

  By adopting a thin air conditioner such as a built-in type as the air conditioner, the lowering dimensions of the lower ceilings 11c and 12c can be minimized, the air conditioner fits well, and the space of the shared portions 11 and 12 is compressed. It does not give a feeling. In addition, by providing a storage room 29 and the like in the attic space 40, the space is effectively used.

  As shown in FIG. 1, when the building H1 is a multi-story high housing, the air conditioners 10 and 20 are provided in the under-the-sky spaces 11a and 12a of the common parts 11 and 12 of each floor. When the resident on the first floor or the second floor of the building H1 is absent and air conditioning is unnecessary, the operation of the air conditioner on the absent floor can be stopped, which can contribute to energy saving. In addition, since ventilation operation (24 hours ventilation) is performed even if air conditioning operation is stopped, the ventilation duty of Building Standard Act can be cleared.

  With the above-described configuration, in the entire building air conditioning system 100, since it is not necessary to separately provide an air conditioner room, installation is possible easily. In addition, by installing the air conditioners 10 and 20 in the ceiling spaces 11a and 12a of the common parts 11 and 12 which are non-residential rooms, it is possible to prevent the diffusion of the operating noise of the air conditioners 10 and 20, Can provide a quiet whole-room air conditioning system.

  Furthermore, by installing the air conditioners 10 and 20 in the ceiling space 11a and 12a of the common portions 11 and 12, the outlet 14 of each room R11, R12, R21, R22 and R23, the branch outlet 14s, and the air conditioner Since the distance to 10 and 20 can be made the shortest, and the route of the duct 23 will also be the shortest, it will be a low pressure loss, and the load of the air conditioners 10 and 20 can be reduced respectively. In addition, since the route of the duct 23 is shortest, the cost of the duct material can be minimized, the construction can be simplified, and the cost can be reduced.

  Thus, the whole building air conditioning system 100 has both the air conditioning function and the ventilation function, can be easily adopted in the building H1 constructed based on the conventional design method, and the workability is good, and the air conditioner The burden of 10 and 20 can also be reduced. In addition, since the entire building air conditioning system 100 can preferentially air-condition the rooms R11, R12, R21, R22 in which the resident is expected to stay for a long time in the building H1, the air conditioning efficiency is improved, and the sensation of the resident The air conditioning energy can be reduced.

  As shown in FIG. 1 and FIG. 2, in the whole building air conditioning system 100, the line-shaped outlet 14 and the branch outlet 14s are used as air supply openings to the respective rooms R11, R12, R21, R22 and R23. The upstream side of the outlet 14 and the branch outlet 14s is connected to the air conditioners 10 and 20 via the chamber 24, the duct 23, and the branch duct 23s.

  As shown in FIG. 9, the chamber 24 combines a portion that continuously widens in the horizontal direction as it goes from the connection port 25 with the duct 23 to the outlet 14, and a portion that continuously shrinks in the vertical direction. A rectifying unit 26 is provided. In addition, since the said air supply opening is not limited to the line-type outlet 14, For example, a long rectangular outlet can be used.

  In the whole building air conditioning system 100, the line-type outlet 14 and the branch outlet 14s as shown in FIG. 9 are used as air supply openings to supply the conditioned air supplied from the air conditioners 10 and 20 to the room R11. By using it, it is possible to reduce the size of the lower ceilings 11c and 12c to the minimum size. Further, since the line-shaped air outlet 14 and the branch air outlet 14s can blow out the conditioned air along the ceiling or wall of the room, the conditioned air spreads throughout the interior of the room, and the efficiency of the air conditioning is improved.

  In the whole building air conditioning system 100, by using the chamber 24 as shown in FIG. 9, the air conditioner 10 installed in the lower ceilings 11c, 12c and the outlet 14 (branch outlet 14s) installed in the wall surface W It can be connected suitably. Further, the chamber 24 has no interference with various members (beams etc.) constituting the lower ceilings 11c and 12c, and the chamber 24 fits well.

  Further, the conditioned air supplied from the duct 23 can smoothly reach the outlet 14 (the branch outlet 14s) by flowing in the chamber 24 having the above-described shape, so that low pressure loss can be achieved. it can. In addition, the chamber 24 is fixed to the component of the building H1 using a screw (not shown) etc. by using a screw (not shown) etc. for the L-shaped metal fitting 24a with a long hole which was detachably attached to the both sides. It can be easily installed in a predetermined place.

  As shown in FIGS. 10 and 11, the air outlet 14 (branch air outlet 14s) has a rotary curved blade 14X capable of adjusting the wind direction and the air volume. The curved blade 14X includes a shallow rod-shaped main body portion 14a, a fan-shaped side plate 14b closing both ends of the main body portion 14a, and a plurality of constant spacings in a direction crossing the concave surface of the main body portion 14a. And a rib 14c. The curved blade 14X is rotatably held in a square cylindrical frame 14e via a support shaft 14d which is provided so as to protrude in the horizontal direction from the side plates 14b at both ends of the main body portion 14a. The front edge portion 14f of the curved blade 14X serves as a manual operation portion when the curved blade 14X is turned.

  Even in the state shown in FIG. 11 (a), the front edge portion 14f of the curved blade 14X protrudes from the front portion of the outlet 14 (branch outlet 14s) to the room R12 side, so manual operation easily from the room R12 side It can be operated. The plurality of ribs 14c disposed at predetermined intervals on the concave curved surface of the main body portion 14a have a function of reinforcing the main body portion 14a and a function of rectifying an air flow described later.

  In the air outlet 14 (branch air outlet 14s), the air volume adjustment and the air direction adjustment can be performed by rotating only one curved blade 14X about the support shaft 14d, so the structure can be simplified. Can be In addition, when the air conditioner 10 is installed in the ceiling space 11a, 12a above the lower ceilings 11c, 12c, the line-shaped outlet 14 (branch outlet 14s) can be installed in the upper part of the wall surface W, so it fits well. The switching operation of the air flow can also be easily performed.

  As shown in FIG. 11 (a), when the front edge portion 14f of the curved blade 14X is pushed until it approaches the front of the frame 14e as far as possible, the outlet 14 (branch outlet 14s) is closed but the main body Since a gap G is secured between the rear edge 14g of the portion 14a and the inner surface of the frame 14e, an air flow can pass through the inside of the blowout port 14. When the front edge portion 14f of the curved blade 14X is pushed until it approaches the front of the frame 14e as far as possible, the front edge 14f is kept projecting from the front surface of the frame 14e.

  When the front edge 14f of the curved blade 14X is pulled out slightly from the front of the frame 14e and the front edge 14f and the rear edge 14g of the curved blade 14X are positioned on the same horizontal plane, as shown in FIG. The conditioned air is blown out from the outlet 14 in the horizontal direction. At this time, as shown in FIG. 12, the conditioned air travels along the ceiling C in the air-conditioned room (room R12) and reaches the wall W1 on the opposite side of the wall W, and then patrols the inside of the room R12. It flows. Therefore, during the cooling operation in summer, it is desirable to set the curved blade 14X of the outlet 14 to the state shown in FIG.

  As shown in FIG. 11C, when the front edge portion 14f of the curved blade 14X is pulled out from the front of the frame 14e to the lowermost portion, the entire curved blade 14X is exposed, and the conditioned air is the main body of the curved blade 14X. It is guided by the concave curved surface portion 14a and the rib 14c, and is blown downward from the air outlet 14 (branch air outlet 14s). At this time, as shown in FIG. 13, the conditioned air descends toward the floor surface F1 in the air conditioning room (room R12), and flows toward the opposite wall W1 of the wall surface W along the floor surface F1. . Therefore, during the heating operation in winter, it is desirable to set the curved vanes 14X of the air outlet 14 (branch air outlet 14s) to the state shown in FIG.

  As described above, in the whole building air conditioning system 100, even when the outlet 14 (branch outlet 14s) is in the closed state as shown in FIG. be able to. Therefore, the 24-hour ventilation function can be secured even in seasons where air conditioning operation is unnecessary, such as in the middle of summer and winter. In addition, since the ventilation air volume in 24-hour ventilation is about 0.5 times / h and relatively small, the gap G is an opening area necessary to distribute the air flow throughout the room.

  As shown in FIG. 1, FIG. 6, and FIG. 7, in the whole building air conditioning system 100, outside air cleaning means (filter box 44 incorporating a filter) for purifying outside air introduced into the ventilator 30 is arranged in the underfloor space 13. doing. Therefore, for example, maintenance of the filter box 44 can be performed from the inspection port 27 provided on the floor surface F1 of the room R11 in the building H1, and the workability is also good. In addition, since the filter box 44 can be maintained from the floor surface F1, it is unnecessary to work at a high place using a stepladder or the like, and the safety is excellent.

  As shown in FIG. 7, a plurality of rubber support members 31 are attached to the lower surface of the ventilation device 30, and the ventilation device 30 is in a state where the support members 31 are grounded to the base surface 13 a of the underfloor space 13. Are disposed in the underfloor space 13. Since the support member 31 has anti-vibration properties, vibration transmission between the ventilator 30 and the base surface 13a can be prevented.

  Further, since the ventilation device 30 is mounted on the base surface 13a of the underfloor space 13 via the plurality of support members 31, as shown in FIG. 8 when performing maintenance of the ventilation device 30, replacement of parts, etc. If necessary, the ventilator 30 can be moved, and the workability is good. In addition, since the ducts 16, 17, 18 and the air supply ducts 19a, 19b connected to the ventilating apparatus 30 are all flexible, the ventilating apparatus 30 can be moved or returned to the original position. When it does, it can follow and deform it, and it does not affect the ventilation function etc.

  Next, in the whole building air conditioning system 100 shown in FIGS. 1 to 5, as shown in FIGS. 14 and 15, the common part 11 is formed on the wall W2 of the dressing room 42 and the common part 11 provided in the building H1. The pipe fan 28 for taking in the conditioned air of the inside of the dressing room 42 is provided.

  Therefore, the conditioned air can be drawn in without installing a duct or the like in the dressing room 42. Moreover, since the inside of the dressing room 42 can be made the same environment as other air-conditioned spaces only by the blowing capacity of the pipe fan 28, it is effective for energy saving.

  In the whole building air conditioning system 100, as shown in FIG. 1, the reversible ductable middle duct fan 41 is provided to connect the buttock space 40 of the building H1 and the room R21 in the building H1 in communication. Therefore, the warm air in the cabin space 40 can be supplied into the room R21 in winter, and the cool air in the room R21 can be supplied in the cabin space 40 in the summer, which is effective in reducing the air conditioning load. It is.

  As shown in FIG. 1 and FIG. 5, since the storage room 29 provided in the cabin back space 40 and the air conditioner 20 are communicated by the branch duct 23s for air supply, from the air conditioner 20 into the storage room 29 By feeding the conditioned air, the same air conditioning as in the other rooms can be performed.

  When constructing the whole building air conditioning system 100 shown in FIG. 1, a heat insulating material such as glass wool can be used for the heat insulation treatment means of the building H1, but from the viewpoint of ensuring air tightness, construction with blowing foam insulation desirable.

  In addition, in the entire building air conditioning system 100, in order to efficiently discharge the air in the building H1 to the outside of the building H via the underfloor space 13, it is an essential requirement to ensure the airtightness of the underfloor space 13 of the building H1. Because of the presence, it is desirable to apply spray foam insulation to the airtight heat insulation treatment means of the underfloor space 13 as well.

  In order to ensure the air tightness of the underfloor space 13, the gap between the air supply ducts 19a and 19b and the floor surface F1 is closed with an air tight tape at a portion where the air supply ducts 19a and 19b penetrate the floor surface F1 shown in FIG. Similarly, the gap between the ducts 17 and 18 and the floor surface F1 is closed with an airtight tape at a portion where the ducts 17 and 18 penetrate the floor surface F1. In addition, the outer peripheral portion of the floor F1 and the base forming the building H1 are fastened with a plurality of gold nails, or the gap between the outer peripheral portion of the floor F1 and the vertical member forming the building H1 is closed with an airtight tape doing. Further, the inspection ports 27, 45 and the opening / closing port 46 shown in FIG. 3 also adopt an airtight type.

  In the duct shaft portion, an airtight process is performed by closing a gap between the duct of a portion where the duct penetrates the structural plywood and the structural plywood with an airtight tape. In the unit bus portion, the base rising portion and the bottom surface are subjected to foam insulation processing, and a unit bus is installed on the base. In addition, in order to provide an inspection port for unit bus inspection, a basic inspection port made of foamed resin with high airtightness is installed at a place where a part of the base rising portion is cut away. As a result, the air in the underfloor space does not flow to the other area via the unit bus portion, and the airtightness of the underfloor space is improved.

  Thus, by ensuring the airtightness of the underfloor space 13, the flow of air to the underfloor space 13 can be shut off via the living room, the unit bus portion, and the duct shaft portion, and the underfloor space 13 from the living room etc. Since the exhaust gas flowing into the air flows into the under floor space 13 only from the exhaust port 15 installed on the floor surface F1, it is possible to prevent the backflow from the exhaust port 15.

  As described above, in the whole building air conditioning system 100, the ventilation function by the ventilation device 30 can be secured by keeping the airtightness of the underfloor space 13 at a high level, and thereby another function, for example, the outlet 14 ( The cooling and heating function by the conditioned air blown out from the branch outlet 14s is also effectively operated.

  Next, based on FIGS. 16-19, the whole building air conditioning system 200 which is other embodiment is demonstrated. In addition, in the whole building air conditioning system 200, about the part which is common with the part which comprises the whole building air conditioning system 100 mentioned above, in FIG. 16-FIG. Omit.

  FIG. 16 shows a schematic configuration of the central air conditioning system 200, and FIGS. 17 to 19 show horizontal cross sections of an actual building H2 provided with the central air conditioning system 200. As shown in FIG. The hatched portions in FIGS. 17 and 18 represent lower ceilings 11 c and 12 c provided on each floor.

  As shown in FIGS. 16-18, on the first floor of the building H2, an entrance hall 1, a corridor 1a, an LDK 2, a storage space 3, a dressing room 7, a storage compartment 8 and the like are provided. 4, a main bedroom 5, Western-style rooms 6, 9 and storage sections 5a, 6a, 9a, etc. are provided, and a storage room 29 is provided in a cabin back space 40.

  Also in the whole building air conditioning system 200, a priority is given to a plurality of areas existing in the building H2 with an area assumed to be short for the residence time of the resident as an upper area, and the shared portion 11 as an area having a higher priority. , 12 are arranged, and the air conditioners 10, 20 are disposed in the ceiling underspaces 11a, 12a above the lower ceilings 11c, 12c formed at positions lower than the ceiling surfaces of the common portions 11, 12.

  As shown in FIG. 17, on the first floor in the building H2, the lower ceiling 11c is formed at a position lower than the ceiling surface of the entrance hall 1, a part of the LDK 2, the dressing room 7 and the storage compartment 8. The air conditioner 10 is disposed in the under-the-sky space 11 a above the lower ceiling 11 c of the entrance hall 1. Thereby, the installation space of the air conditioner 10 can be easily secured, and it is not necessary to separately provide an air conditioner room. In addition, since it is difficult for the operating noise of the air conditioner 10 to reach a region where the resident's stay time is long (such as LDK 2), silence can be ensured.

  Further, as shown in FIGS. 16 and 17, in the first floor portion of the building H2, the air outlet 14 and the branch air outlet 14s are disposed on the wall surfaces 11d, 11e, 11h, and 11i adjacent to the ceiling underspace 11a. .

  By providing two outlets 14 and 14 in LDK 2, in the area where it is assumed that the residence time of the resident is long, it is possible to preferentially air-condition the part where the resident is expected to stay for a long time It is effective in improving the efficiency of air conditioning and reducing the energy of air conditioning. In addition, branch outlets 14s and 14s are provided in the entrance hall 1 and the kitchen K, which are areas assumed to have a shorter residence time of a resident than in a living room and the size (volume) of the area is smaller. Since the proper conditioned air can be supplied to the place where the conditioning load is low, the temperature distribution in the building H2 can be made uniform.

  As described above, the air conditioner 10 and the air outlet 14 are connected by the duct 23, and the air conditioner 10 and the branch air outlet 14s are connected by the branch duct 23s divided into two from the duct 23 (from the air outlet 14 It is set so that it may be set to (the amount of blow-off air from branch outlet 14s) of the amount of blow-off air of the above. Therefore, it is possible to suppress the supply of the conditioned air to the portion where the stay of the resident is expected to be short, while preferentially conditioning the portion where the stay time of the resident is expected to be long, It is effective for improvement and reduction of air conditioning energy.

  The downstream side of the duct 23f is divided into two branch ducts 23s and 23s, and the downstream side of one branch duct 23s is connected to a branch outlet 14s provided on a wall surface 80a facing the Western-style room 80, and the other branch duct 23s The downstream side is connected to a branch outlet 14s provided on a wall surface 81a facing the Western-style room 81.

  Further, as shown in FIG. 27, a lower ceiling 88 (hatched portion) is provided below the ceiling portion of the area where the residence time of the resident is assumed to be short on the second floor portion of the building H4. The air conditioner 20, the air supply duct 19b, the ducts 23d, 23e, 23f, and the branch duct 23s are disposed in the space under the ceiling of the wall, and the wall surface 80a, 81a, 82a, 83a and the ceiling step portion in the area adjacent to the lower ceiling 88 The blower outlet 14 or the branch blower outlet 14s is installed at 84a. Therefore, in the space above the lower ceiling 88, the chamber 24 (see FIG. 9) for connecting the ducts 23d, 23e, 23f (branch ducts 23s) and the outlet 14 (branch outlet 14s) can be accommodated. And the chamber 24 fits well.

  As shown in FIGS. 25 to 27, in the whole building air conditioning system 400, the residence time of the resident such as the entrance hall 50, the kitchen K, the hall 82 and the walk-in closet 84 is not as long as living, dining and living room The branch outlets 14s are also arranged in the area for the pedestrians to pass and in the area for the resident to temporarily stay for the specific purpose. As a result, since the air conditioning inside the building H4 can be performed uniformly, the air conditioning efficiency can be improved, the occupants' sensation can be improved, and the air conditioning energy can be reduced.

  In addition, since the air volume of the branched duct 23s divided into two from the ducts 23a to 23f is half of the air volume of the original ducts 23a to 23f, the air conditioning of the portion assumed to have a long residence time of the resident is preferentially air conditioned While, it becomes possible to suppress the supply of the conditioned air to the portion where it is assumed that the stay of the resident is short, which is effective in improving the efficiency of the air conditioning and reducing the energy of the air conditioning. In addition, the size (volume) of the area is small, and it is possible to supply appropriate conditioned air to the portion where the air conditioning load is low, and it is possible to make the temperature distribution in the building H4 uniform.

  The whole building air conditioning system 100, 200, 300, 400 described based on FIGS. 1 to 27 is an example of the whole building air conditioning system according to the present invention, and the whole building air conditioning system according to the present invention is the whole building described above. It is not limited to the air conditioning system 100, 200, 300, 400.
