Each of the floor panels 81A to 81C has a floor finishing surface material 85 that forms the floor surface of the second-floor living room 35, and a floor foundation surface material 86 provided on the lower surface of the floor finishing surface material 85. Therefore, each floor panel 81A to 81C has a two-layer structure composed of the double-sided materials 85 and 86. The floor finishing surface material 85 of each floor panel 81A to 81C is formed of, for example, a flooring material, and is fixed to the floor base surface material 86 with a nail or the like.

In the floor panel 81A, the floor base surface material 86 is formed of, for example, particle board. An air supply grill 54 is attached to the floor panel 81A. The air supply grill 54 is attached in a state of being fitted into an opening 84 formed in the floor panel 81A. Further, the air supply grill 54 has a rectangular shape and is attached at a position displaced from the center of the floor panel 81A. The air supply grill 54 corresponds to the air supply port.

The floor panel 81B of the floor panel 81B is made of a material having higher thermal conductivity than the floor substrate 86 of the other floor panels 81A and 81C. The floor base surface material 86 of the floor panel 81B (hereinafter, also referred to as the floor base surface material 86B) is formed of a metal material having excellent thermal conductivity such as aluminum.

The floor base material 86 of the floor panel 81C is formed of, for example, particle board, similarly to the floor base material 86 of the floor panel 81A. The floor panel 81C is the floor panel 81 other than the floor panels 81A and 81B among the floor panels 81A to 81C. The floor base surface material 86 of the floor panel 81C does not necessarily have to be formed of the same particle board (and thus the same material) as the floor base surface material 86 of the floor panel 81A, and may be formed of a different material.

Next, the configuration regarding the air conditioning of the first-floor room 31 and the second-floor room 35 will be described.

As shown in FIG. 4, an air conditioning duct 52 is connected to each air supply grill 54 provided on each ceiling panel 61A (corresponding to an air supply panel) of the ceiling panel juxtaposed portion 62. In this case, the conditioned air generated by the air conditioner 51 is supplied to the air supply grills 54 of each ceiling panel 61A through the air conditioning ducts 52 and is blown from the air supply grills 54 toward the first-floor room 31. Thereby, the air-conditioning (cooling/heating) of the first-floor living room 31 is performed by the blown-out conditioned air.

Air conditioning ducts 52 are connected to air supply grills 54 provided on each floor panel 81A (corresponding to an air supply panel) of the floor panel juxtaposed portion 82. In this case, the conditioned air generated by the air conditioner 51 is supplied to the air supply grills 54 of each floor panel 81A through the air conditioning ducts 52, and is blown from the air supply grills 54 toward the second-floor living room 35. Thereby, the air-conditioning (cooling/heating) of the second-floor living room 35 is performed by the blown-out conditioned air.

Of the air conditioning ducts 52 introduced into the inter-floor space 43a, some of the air conditioning ducts 52 are unconnected ducts that are not connected to the air supply grill 54. The air conditioning duct 52 (hereinafter, referred to as 52A) is provided in a state where the air supply chamber 53 provided at the end thereof is placed on the ceiling panel 61 (for example, the ceiling panel 61B). In this case, the conditioned air generated by the air conditioner 51 is supplied to the air supply chamber 53 through the air conditioning duct 52A and is blown from the air supply chamber 53 to the inter-floor space 43a. Thereby, the air-conditioning (cooling/heating) of the inter-floor space 43a is performed by the blown-out conditioned air. In this case, the inter-floor space portion 43a corresponds to the back room space, and the air conditioning duct 52A corresponds to the air carrying member.

Here, the configuration around the inter-floor space portion 43a will be described with reference to FIG. As shown in FIG. 3, around the inter-floor space 43a, the ceiling girder 22 of the building unit 20 of the first-floor portion 14 and the floor girder 23 of the building unit 20 of the second-floor portion 15 are vertically opposed to each other, The inter-floor space portion 43a is surrounded by the ceiling girders 22 and the floor girders 23 arranged so as to face each other. In the gap 45 between the ceiling girder 22 and the floor girder 23 which are arranged opposite to each other, a closing member 78 for closing the gap 45 is provided. The closing member 78 is made of, for example, glass wool, and is arranged over the entire circumference of the inter-floor space portion 43a. Although not shown, a closing member is also provided in the beam through hole 22a of each ceiling girder 22 provided around the inter-floor space 43a, and the beam through hole 22a is closed by the closing member. .. Thereby, in the inter-floor space portion 43a, the outflow of air to the surroundings is suppressed, and therefore the inter-floor space portion 43a is a so-called closed space.

Returning to the description of FIG. 4, each ceiling panel 61B (corresponding to a radiation panel) of the ceiling panel juxtaposed portion 62 is provided with its upper surface facing the inter-floor space portion 43a. In this case, heat (cold heat or warm heat) of the inter-floor space portion 43a that is air-conditioned (cooled/heated) by the air conditioner 51 is transmitted to each of the ceiling panels 61B. This heat is conducted from the upper surface of the ceiling panel 61B toward the lower surface (ceiling surface), and is radiated from the lower surface to the first-floor room 31. Then, the radiated heat air-conditions (cools and heats) the first-floor room 31. Therefore, the first-floor living room 31 is cooled and heated by both the conditioned air blown from the air supply grill 54 and the radiant heat radiated from the ceiling panel 61B.

Each floor panel 81B (corresponding to a radiation panel) of the floor panel juxtaposed portion 82 is provided such that the lower surface of the floor base material 86B faces the inter-floor space portion 43a. In this case, the heat of the floor space 43a is transmitted to the floor base surface material 86B of each floor panel 81B. This heat is conducted from the lower surface of the floor base material 86B to the upper surface, and is radiated from the upper surface to the second-floor living room 35 through the floor finishing surface material 85. Then, the radiated heat causes air conditioning (cooling/heating) of the second-floor living room 35. Therefore, the second-floor room 35 is cooled and heated by both the conditioned air blown from the air supply grill 54 and the radiant heat radiated from the floor panel 81B.

Next, the configuration regarding the connection between the air conditioning duct 52 and the air supply grill 54 will be described.

As described above, the air conditioning duct 52 is connected to the air supply grill 54 of each ceiling panel 61A and the air supply grill 54 of each floor panel 81A. These air conditioning ducts 52 are connected to an air supply grill 54 via an air supply chamber 53. In this case, the air supply chamber 53 is a connecting portion that connects the air conditioning duct 52 to the air supply grill 54.

The air supply chamber 53 of each of the air conditioning ducts 52 is detachably connected to the air supply grill 54. The air supply chamber 53 is connected to the air supply grill 54 using a fastening member such as a bolt, and can be attached to and detached from the air supply grill 54 by bringing the fastening member into a fastening state or a fastening release state. The air supply chambers 53 of the air conditioning ducts 52 have the same configuration. Therefore, the air supply chamber 53 of each air conditioning duct 52 can be connected to both the air supply grill 54 of each ceiling panel 61A and the air supply grill 54 of each floor panel 81A.

Of the air conditioning ducts 52 introduced into the inter-floor space 43a, the air supply chamber 53 of the air conditioning duct 52A (unconnected duct) not connected to the air supply grill 54 is also connected to the air supply grill 54. It has the same configuration as the air supply chamber 53 of the duct 52 (connection duct). Therefore, the air supply chamber 53 of the air conditioning duct 52A can be connected to both the air supply grill 54 of each ceiling panel 61A and the air supply grill 54 of each floor panel 81A.

Next, a work procedure for relocating the ceiling panel 61 and the floor panel 81 will be described.

When rearranging the ceiling panel 61, first, the ceiling panel 61 to be rearranged is removed from the support rail 71. In this removal work, first, of the ceiling panels 61A to 61D, the ceiling panel 61B (radiation panel) and the ceiling panel 61D (normal panel) are removed from the support rail 71. Then, the air conditioning duct 52 (air supply chamber 53) connected to the air supply grill 54 of the ceiling panel 61A (air supply panel) is removed through the opening opened by the removal (see FIG. 7), and the ceiling panel 61C ( The connector 67a of the electric wiring 67 provided on the lighting panel) is removed from the connector 69a of the electric wiring 69. Then, thereafter, the ceiling panels 61A and 61C are removed from the support rail 71.

Next, a work for rearranging the removed ceiling panels 61 is performed. In this work, first, each ceiling panel 61A, 61C is fixed on the support rail 71 using a magnet 72. Then, the air conditioning duct 52 (air supply chamber 53) is connected to the air supply grill 54 of the ceiling panel 61A, and the electric wiring 67 of the ceiling panel 61C is connected to the electric wiring 69 using the connectors 67a and 69a. After that, the remaining ceiling panels 61B and 61D are fixed on the support rail 71 by using a magnet 72. This completes the rearrangement of the ceiling panel 61.

Further, in the above-mentioned rearrangement, when there is a ceiling panel 61 in which the rearrangement destination of the ceiling panel 61 is on the same support rail 71, the rearrangement work is performed using the support rail 71 for the ceiling panel 61. I do. In this case, as shown in FIG. 7, the ceiling panel 61 is slid to the rearrangement destination while being supported by the support rails 71. In this sliding movement, first, the ceiling panels 61 are supported on the respective support rails 71 until the magnets 72 of the ceiling panel 61 are separated from the support rails 71, that is, the positions where the fixation of the ceiling panel 61 by the magnets 72 is released. Egg it. Then, at the fixing release position, the ceiling panel 61 is slid along the support rails 71 to the rearrangement destination. After the movement, the ceiling panel 61 is shifted to a position where the magnet 72 of the ceiling panel 61 is attracted to the support rail 71, that is, a position where the ceiling panel 61 is fixed by the magnet 72. This completes the rearrangement of the ceiling panel 61.

Next, a procedure for rearranging the floor panel 81 will be described. When relocating the floor panel 81, first, the floor panel 81 to be relocated is removed from the floor beam 26. In this removal, first of all the floor panels 81, the floor panel 81B (radiation panel) and the floor panel 81C (normal panel) are removed. At the time of this removal, for example, an elongated hooking jig may be inserted into the gap between the floor panels 81, and the floor panel 81 may be hooked and removed by the jig. After removing each floor panel 81B, 81C, the air conditioning duct 52 (air supply chamber 53) connected to the air supply grill 54 of the floor panel 81A (air supply panel) is removed through the opening opened by the removal. Then, the floor panel 81A is removed from the floor beam 26.

Subsequently, a work for rearranging the removed floor panel 81 is performed. In this work, first, the floor panel 81A is installed on the floor beam 26, and the air conditioning duct 52 (air supply chamber 53) is connected to the air supply grill 54 of the floor panel 81A. Then, each floor panel 81B, 81C is installed on the floor beam 26. This completes the rearrangement of the floor panel 81.

Next, an example of rearrangement of the ceiling panel 61 and the floor panel 81, which is performed when furniture is rearranged in the first-floor room 31 and the second-floor room 35, will be described. First, when furniture is rearranged in the first-floor room 31, rearrangement of the ceiling panel 61, which is accompanied with the rearrangement, will be described with reference to FIG. FIG. 8 is a plan view showing the first-floor living room 31, in which (a) shows a state before the rearrangement of furniture, and (b) shows a state after the rearrangement of furniture. Note that, in FIGS. 8A and 8B, for the sake of convenience, each ceiling panel 61 and its accompanying members are shown by a chain line. In addition, in the following example, it is assumed that furniture is rearranged as a child is born and raised.

As shown in FIG. 8A, the first-floor room 31 is an LDK in which a living room, a dining room, and a kitchen are continuous. The first-floor living room 31 is divided on three sides by partition walls 56 (56a to 56c). Before the furniture is rearranged, a sofa 91 is installed in the living room along the partition wall 56b and a dining table 92 is installed in the dining room in the living room 31 on the first floor.

On the other hand, after the furniture is rearranged, as shown in FIG. 8B, the sofa 93 is installed along the partition wall 56a in the living room in the first-floor room 31, and the dining room is installed. A dining table 94 is installed in. The position of the dining table 94 is slightly closer to the partition wall 56b than that before the furniture is rearranged (dining table 92). A crib 95 is installed near the partition wall 56c.

With such a rearrangement of furniture, the ceiling panels 61A to 61D are rearranged in the first-floor room 31. For example, before the rearrangement of furniture, the air supply grills 54 of the ceiling panel 61A (air supply panel) were arranged at a position right above the sofa 93 and a position right above the crib 95, respectively. In that case, the conditioned air blown out from the air supply grill 54 may directly hit the person sitting on the sofa 93 and the child on the crib 95. Therefore, in order to avoid such a situation, the ceiling panel 61A is moved to a position different from the position just above the sofa 93 and the position just above the crib 95 after rearranging the furniture.

Moreover, since the position of the dining table 94 is shifted to the partition wall 56b side due to the rearrangement of furniture, the position of the ceiling panel 61C (illumination panel) is changed accordingly. That is, in this case, as the position of the dining table 94 is changed, the position of the lighting fixture 65 attached to the hook ceiling 66 of the ceiling panel 61C is changed.

Next, when furniture is rearranged in the second-floor room 35, rearrangement of the floor panel 81, which is accompanied with the rearrangement, will be described with reference to FIG. 9. 9A and 9B are plan views showing the second-floor living room 35, where FIG. 9A shows a state before the rearrangement of furniture, and FIG. 9B shows a state after the rearrangement of furniture. In the following example, it is assumed that furniture is rearranged in the second-floor room 35 as the child grows up.

As shown in FIG. 9A, the second-floor living room 35 is used as a child room. The second-floor living room 35 is, for example, a child room shared by two children. Before the furniture is rearranged, the table 96 is installed in the center of the second-floor living room 35 and the bed 97 is installed in the corner.

On the other hand, after the furniture is rearranged, as shown in FIG. 9B, the space between the juxtaposed portions 82a and 82b of the floor panel juxtaposed portion 82 in the second-floor room 35. A partition 98 is installed at 83. Thereby, after the furniture is rearranged, the partition 98 divides the second-floor room 35 into two regions 35a and 35b. Each of the divided areas 35a and 35b is used as a child room for each child. Beds 99a and 99b are installed in the areas 35a and 35b of the second-floor room 35, respectively.

In accordance with such a rearrangement of furniture, the floor panels 81A to 81C are rearranged in the second-floor room 35. For example, before rearrangement of furniture, the air supply grill 54 of the floor panel 81A (air supply panel) was arranged at a position directly below the bed 99a. In that case, the air supply grill 54 may be blocked by installing the bed 99a. Therefore, in order to avoid such a situation, the floor panel 81A is moved to a position different from the position directly below the bed 99a after rearranging the furniture.

Further, before the rearrangement of furniture, the floor panel 81B (radiation panel) is integrated in the side-by-side portion 82b of the side-by-side arranged portions 82a, 82b, but after the rearrangement of the furniture, the side-by-side portions 82a are arranged. , 82b are respectively provided with floor panels 81B. This makes it possible to air-condition each area 35a, 35b of the second-floor living room 35 by radiant heat from the floor panel 81B.

In the area 35b (the juxtaposed portion 82b), there is an area where the chair 101a and the table 101b are installed near the partition 98, and the floor panel 81B is arranged in accordance with this area. In this case, when the floor panel 81A (air supply panel) is arranged in accordance with the area, the air supply grill 54 is blocked by the chair 101a or the like, or the conditioned air blown out from the air supply grill 54 directly hits and causes discomfort. There is a risk of inconvenience such as feeling. In this respect, by arranging the floor panel 81B so as to match the area, it is possible to locally air-condition the area while avoiding such inconvenience.

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

In the ceiling panel juxtaposed part 62 of the first-floor room 31, the ceiling panels 61 are provided so as to be interchangeable with each other, and each ceiling panel 61 is provided with an air supply grill 54. 61A is included. In this case, the position of the air supply grill 54 can be changed by changing the arrangement of the ceiling panels 61. Therefore, when the arrangement of furniture is changed or the floor plan is changed, the air supply grill 54 is changed accordingly. The position of 54 can be changed. Thereby, when the furniture is rearranged or the floor plan is changed in the first-floor room 31, it is possible to appropriately deal with the rearrangement and the like.

In the floor panel juxtaposed portion 82 of the second-floor living room 35, the floor panels 81 are provided so as to be interchangeable with each other, and each floor panel 81 is provided with an air supply grill 54. It is included. In this case, it is possible to change the position of the air supply grill 54 by changing the arrangement of the floor panels 81. Therefore, when the arrangement of furniture is changed or the floor plan is changed, the air supply grill 54 is changed accordingly. The position of 54 can be changed. Accordingly, when the rearrangement of furniture or the layout of the furniture is changed in the second-floor room 35, it is possible to appropriately deal with the rearrangement or the like.

Each ceiling panel 61 of the ceiling panel juxtaposed portion 62 includes a plurality of ceiling panels 61A for air supply, and the air supply grills 54 of the respective ceiling panels 61A each receive conditioned air generated by the air conditioner 51. It is adapted to be transported through the air conditioning duct 52. Further, similarly, each floor panel 81 of the floor panel juxtaposed portion 82 includes a plurality of air supply floor panels 81A, and the air supply grills 54 of the respective floor panels 81A each include an air conditioner 51. The conditioned air generated by the above is conveyed through the air conditioning duct 52.

In such a configuration, each air conditioning duct 52 is provided with the air supply chamber 53 that detachably connects the air conditioning duct 52 to the air supply grill 54. In this case, when the ceiling panel 61A is relocated or the floor panel 81A is relocated, the air conditioning duct 52 (air supply chamber 53) can be removed from the air supply grill 54 and relocated. .. This makes it possible to easily rearrange the ceiling panel 61A and the floor panel 81A in a configuration in which conditioned air is conveyed by a duct.

The air supply chamber 53 of each air conditioning duct 52 can be connected to both the air supply grill 54 of each ceiling panel 61A and the air supply grill 54 of each floor panel 81A. In this case, after rearranging each ceiling panel 61A and each floor panel 81A, when connecting the air conditioning duct 52 to the air supply grills 54 of the respective panels 61A and 81A, the air conditioning ducts near the air supply grill 54 are connected. It is possible to connect 52 to the air supply grill 54. This can facilitate the (re)connection work of the air conditioning duct 52 to each air supply grill 54, which is performed after the rearrangement of the panels 61A and 81A. Particularly, in the above-described embodiment, since each air conditioning duct 52 can be connected to the air supply grill 54 of the first floor ceiling (ceiling panel 61A) and the air supply grill 54 of the second floor (floor panel 81A), respectively. It becomes possible to greatly facilitate the work of connecting the air conditioning duct 52 to the air supply grill 54.

Since a part of the conditioned air generated by the air conditioner 51 is conveyed to the inter-floor space 43a, the air-conditioning (cooling/heating) of the inter-floor space 43a is performed by the conditioned air. Further, each ceiling panel 61 of the ceiling panel juxtaposed portion 62 includes a heat radiation ceiling panel 61B, and each floor panel 81 of the floor panel juxtaposed portion 82 includes a heat radiation floor panel 81B. It is included. In this case, the heat of the inter-floor space 43a is radiated to the first-floor room 31 via the ceiling panel 61B, and is radiated to the second-floor room 35 via the floor panel 81B. As a result, the first-floor room 31 and the second-floor room 35 can be air-conditioned by the radiant heat radiated from the ceiling panel 61B and the floor panel 81B in addition to the conditioned air blown from the air supply grill 54. Therefore, it is possible to efficiently air-condition the first-floor room 31 and the second-floor room 35 by using air-supply (convection) of conditioned air and heat radiation in combination.

Further, each ceiling panel 61 including the ceiling panel 61B can be rearranged, and each floor panel 81 including the floor panel 81B can be rearranged. In this case, for example, while it is desired to avoid direct contact with the conditioned air blown from the air supply grill 54, the area is locally air-conditioned (for example, the area where the chair 101a and the table 101b are installed in the area 35b of the second-floor living room 35). ), the floor panel 81B can be arranged according to the area. As a result, it becomes possible to more appropriately deal with the rearrangement of furniture and the change of floor plan.

An air supply chamber 53 that detachably connects the air conditioning duct 52 to an air supply grill 54 is provided in each air conditioning duct 52 introduced into the inter-floor space 43a. Then, some of the air conditioning ducts 52 are connected to the air supply grills 54 (of the respective panels 61A and 81A) by the air supply chamber 53 so that the conditioned air is conveyed to the air supply grills 54. The other air conditioning duct 52 is not connected to the air supply grill 54 by the air supply chamber 53, and is used as an air transfer member for transferring the conditioned air to the inter-storey space 43a.

In such a configuration, each of the air conditioning ducts 52 can be used to convey the conditioned air to the air supply grill 54, and can be used to convey the conditioned air to the inter-storey space 43a. Therefore, after the rearrangement of the ceiling panel 61 or the floor panel 81, when the air conditioning duct 52 is (re)connected to the air supply grill 54 (of each of the panels 61A and 81A), it is near the air supply grill 54. It is possible to connect the air conditioning duct 52 to the air supply grill 54 and use the air conditioning duct 52 at a position apart from the air supply grill 54 as an air carrying member without connecting it to the air supply grill 54. This makes it easier to (re)connect the air conditioning duct 52 to the air supply grill 54 after the rearrangement of the panels 61 and 81.

Each ceiling panel 61 of the ceiling panel juxtaposed portion 62 includes an illumination ceiling panel 61C provided with a hook ceiling 66 for attaching the lighting fixture 65. In this case, it is possible to change the arrangement position of the lighting fixture 65 by changing the arrangement of the ceiling panel 61C. As a result, the arrangement position of the lighting fixture 65 can be changed according to the rearrangement of the furniture and the change of the floor plan. Therefore, the rearrangement of the furniture and the like can be suitably dealt with in terms of the illumination of the first-floor room 31. It becomes possible.

The ceiling panel 61 is slidably supported by a pair of support rails 71 provided on the ceiling of the first-floor room 31. In this case, when the rearrangement of the ceiling panel 61 is performed, the rearrangement can be performed while sliding the ceiling panel 61 on the support rail 71, so that the rearrangement of the ceiling panel 61 can be facilitated. ..

Further, since each ceiling panel 61 is detachably fixed to the support rail 71 by the magnet 72, each ceiling panel 61 can be easily attached and detached. As a result, the work of rearranging the ceiling panels 61 can be facilitated.

The ceiling panels 61 of the ceiling panel juxtaposed portion 62 have the same shape and the same size in plan view. Thereby, since each ceiling panel 61 can be replaced with any other ceiling panel 61, variations in the arrangement mode of each ceiling panel 61 can be increased and the arrangement of each ceiling panel 61 can be easily changed. Is possible. Similarly, each floor panel 81 of the floor panel juxtaposed portion 82 has the same shape and the same size in a plan view, so that the floor panel 81 can also obtain the same effect as described above.

In the ceiling panel 61A for air supply, the air supply grill 54 is arranged at a position displaced from the center of the panel 61A. In this case, by changing the arrangement direction of the ceiling panel 61A, the position and direction of the air supply grill 54 can be (slightly) changed. As a result, more detailed correspondence can be made according to the rearrangement of furniture or the like. Also, the same effect as above can be obtained for the floor panel 81A for air supply.

The present invention is not limited to the above embodiment and may be implemented as follows, for example.

In the above-described embodiment, each ceiling panel 61 of the ceiling panel juxtaposed portion 62 includes the ceiling panel 61A for heat supply, the ceiling panel 61B for heat radiation, and the ceiling panel 61C for illumination. At least one of the ceiling panels 61B and 61C may not be included. In addition, in the above-described embodiment, each floor panel 81 of the floor panel juxtaposed portion 82 includes the floor panel 81A for air supply and the ceiling panel 61B for heat radiation, but the ceiling panel 61B is not included. You may do it. Even in these cases, the position of the air supply grill 54 can be changed by changing the arrangement of the air supply panels 61A and 81A according to the change of the furniture arrangement. It becomes possible to respond appropriately.

-For example, each ceiling panel 61 of the ceiling panel juxtaposed portion 62 may include the ceiling panel 61 for facility equipment to which the equipment is attached. In this case, the equipment may be an audio device such as a speaker or a video device. In such a configuration, the arrangement position of the equipment can be changed by changing the arrangement of the ceiling panel 61. Therefore, from the viewpoint of indoor equipment, it is possible to appropriately deal with furniture relocation and the like.

In the above embodiment, the conditioned air generated by the air conditioner 51 is conveyed to the air supply grill 54 of each panel 61A, 81A using the air conditioning duct 52, but this may be changed. For example, it is conceivable that the air conditioning duct 52 connected to each air supply grill 54 is not provided and only the air conditioning duct 52 (52A) that conveys the conditioned air is provided in the inter-floor space portion 43a. In this case, the conditioned air is supplied from the air conditioner 51 to the inter-floor space 43a through the air-conditioning duct 52, and the conditioned air is blown from the inter-floor space 43a through the air supply grills 54 to the first-floor room 31 and the second-floor room 35. Will be done. Therefore, also in this case, it is possible to air-condition the first-floor room 31 and the second-floor room 35 by the conditioned air blown out from the air supply grill 54.

In the above embodiment, the ceiling panel juxtaposed portion 62 is provided on the ceiling of the first floor living room 31, but the floor panel juxtaposed portion may be provided on the floor of the first floor living room 31. In this case, each floor panel constituting the floor panel juxtaposed portion can be rearranged, and the floor panel for air supply provided with the air supply grill 54 may be included in each floor panel.
