2. Description of the Related Art Conventionally, residential air conditioning in Japan has been centered on cooling and heating by merely adjusting the temperature, and has been a simple one that is performed for each room in a house. Moreover, since the housing structure in Japan has traditionally been an open structure that adapts to the natural environment, it is difficult to secure heat insulation and airtightness,
It was unsuitable as an air-conditioning target in terms of ensuring the comfort of living and energy efficiency. On the other hand, in recent years, housings having improved heat insulation and airtightness are becoming widespread for the purpose of ensuring comfort of living and energy saving. For this reason, it becomes indispensable to maintain the air quality in each room by planned ventilation with the insulation and airtightness of the house.
As described above, a simple air conditioning system for each room mainly for temperature control, that is, a system of individually installing a cooling / heating machine in each room has become unsuitable. Along with this, there has been a demand for an air conditioning system in which the quality of air in the room is maintained, the temperature and cooling are controlled, and the conditioned air is well distributed to each room. However, such air quality maintenance, hot and cold,
An air conditioning system capable of controlling humidity and distributing (reducing) conditioned air to each room satisfactorily becomes expensive, so it is desirable to realize such an air conditioning system inexpensively and easily. ing.

FIG. 14 shows a building 900 which is an example of a conventional building in which an air conditioner is installed in such a situation. The building 900 is a two-story building, and air-conditioned spaces 901 and 902 to be air-conditioned are provided on each floor. Space 904 below the floor covering 903 of the air-conditioned space 901 on the first floor
And the ceiling 905 of the air-conditioned space 901 on the first floor and the air-conditioned space 90 on the second floor.
The space 907 between the second floor material 906 and the air-conditioned space 90 on the second floor
The space 909 above the second ceiling 908 has a duct for air conditioning.
910, 911, 912, 913 and the like are appropriately provided, and these ducts 910 to 913 are connected to the respective air conditioning spaces 901 and 902 by the air supply / exhaust ports 914, 915, 916, 917, 918 and the like, and constitute an air conditioner together with an air conditioner (not shown). The ducts 910 to 913 may be provided inside the wall body 919. The ducts 910 to 913 are flexible ducts, round ducts, rectangular ducts, and the like.

Further, as another example of installation of the air conditioner, there is also an example in which a ventilation system that does not use the ducts 910 to 913 is applied. For example, on the first floor, the floor surface material of FIG.
The space 904 surrounded by the foundation 920 below the 903 is provided with airtightness and heat insulation, and by being installed so as to prevent ingress of moisture from the ground, the space 904 is thermally insulated from the outside. The space 904 is also supplied with hot and cold heat and fresh air for air conditioning. In other words, it is a blowing method in which the space 904 itself is used instead of providing the duct 910. Furthermore, a method is also used in which the floor coverings 903 and 906 of the air-conditioned spaces 901 and 902 are duplicated and a ventilation layer for supplying air for air conditioning is formed therebetween.

[0005]

However, in the air conditioner using the ducts 910 to 913 described above, the duct 910
~ Spaces 904, 90 located around the air-conditioned spaces 901, 902 in Fig. 14 to secure space for installing 913
The height dimension of 7,909 must be increased. For this reason, the floor height H1 is set to a larger dimension than the normal building in preparation for cost increase, or the floor height H1 is set to a normal dimension,
There is a problem that the ceiling height H2 must be sacrificed. In addition, the work of installing the ducts 910 to 913 is complicated and time-consuming, and the construction cost is high. Furthermore, such ducts 910-913
The method of installing is not widely used by home designers and contractors, and is not preferred.

Further, in the method of thermally insulating the entire space 904 from the outside in FIG. 14, since moisture protection under the floor is important, it is necessary to perform a troublesome construction such as covering the bottom surface 921 of the space 904 with concrete. There is a problem that the construction cost increases. Furthermore, the method of duplicating the floor coverings 903 and 906 of FIG. 14 and forming the ventilation layer between them also has a problem in that construction is time-consuming and construction cost is increased.

An object of the present invention is to provide a floor structure, an air conditioner and a floor heating device which can be easily and inexpensively constructed and have good energy efficiency.

In the present invention as described above, the airtight membrane material is provided on the lower side of the floor surface material, and a space for enclosing air is formed between the floor surface material and the membrane material. As an aeration layer, air for air conditioning and air for heating are sent from here to an air conditioner and a floor heater. Due to the special floor structure with such a membrane material, a ventilation layer is formed over the entire floor surface under the floor material, and by providing an outlet at an appropriate place on the floor material, The air-conditioning space is supplied with air for air-conditioning as much as necessary at a necessary place, and an air-conditioning device is easily and inexpensively configured. Further, by sending heating air into the ventilation layer to perform floor heating, good floor heating is configured in which heating heat is supplied from the entire floor surface to the upper heating space through the floor material. .

Further, since the installation of the film material is carried out by using the conventional building structure, particularly the structure of the wooden house which is premised on the traditional natural ventilation of our country as it is, it does not take time and effort for the construction. There is no significant change in the building structure. As compared with the method of installing the ducts 910 to 913 and the like shown in FIG. 14 to configure the air conditioner and the floor heating apparatus, the space for installation is not required, so the floor height H1 of FIG. 14 is increased.

Further, there is no possibility of causing vibration of the pipes such as the ducts 910 to 913.

Further, when heating is performed in the air conditioner, in addition to the supply of air for air conditioning into the air-conditioned space from the outlet provided in the floor surface material, radiation is radiated to the air conditioning space through the floor material. There is also floor heating at the same time. Therefore, the temperature of the air-conditioning air supplied from the outlet to the air-conditioned space is set to the minimum temperature difference from the room temperature of the air-conditioned space, so that comfortable heating is realized. As a result, sufficient heating can be realized even with a heat exchange type heat pump that does not require electric resistance heating in the winter, and the above-mentioned objects are achieved.

81 is provided, the partition wall body 180 has a door 182, and a ventilation path 184 is formed so as to penetrate the door 182 by a door louver or the like. On the other hand, a ventilation passage 185 is formed in the partition wall body 181 by a sound deadening register or the like. The air passages 184 and 185 allow the air conditioning air 32B in the air conditioning spaces 13 and 14 to be discharged to the passage space 16. The structure inside each partition wall body 180, 181 is substantially the same as the structure inside each partition wall body 80, 81 on the first floor portion, and a heat insulating material 84 that functions as a wind stop is provided. Partition wall body 18
A suction port 186 equipped with a filter is provided on the side surface of the passage space 16 side of 1.The air conditioning air 32B exhausted into the passage space 16 is filtered by the suction port 186 and
It is designed to be returned to the air conditioner 31B through the inside of the partition wall body 181. This is the end of the description of the structure of the second floor of the building 10 including the air-conditioned spaces 13 and 14 and the floor structure 150 thereof and the configuration of the air conditioner 30B on the second floor.

In the first embodiment, the air conditioning of each floor is performed as follows. In the first embodiment, the air conditioning of the first floor part and the second floor part are separate air conditioners 30A,
It will be done at 30B. On the first floor, first, the air conditioner 30
32 A of fresh air-conditioned air that has been variously air-conditioned is discharged from A into the pit space 17 under pressure.
Sent in. Here, the various air conditioning processes include ventilation (intake, scavenging), cooling / heating (temperature control), dehumidification, humidification, and the like. Next, the air-conditioning air 32A in the ventilation layer 58 is supplied to the air-conditioned spaces 11 and 12 on the first floor from the outlets 70 appropriately provided in the floor covering 56. Thereafter, the air conditioning air 32A in each air conditioning space 11, 12 is exhausted to the passage space 15 from the air passages 82, 83 provided in the partition walls 80, 81, and returned to the air conditioner 31A through the suction port 85. Be done. Similarly, in the second floor, first, the air conditioner 30B
Fresh air conditioning air 32B, which has been subjected to various air conditioning treatments, is pressurized and released into the pit space 18 from the air conditioning layer 15 through the ventilation path 165.
It is sent within 8. Next, the air conditioning air in the ventilation layer 158.

Is exhausted to the passage space 16 from the air passages 184 and 185 provided in the partition walls 180 and 181, and the air conditioner 31B from the suction port 186.
Returned to.

According to such a first embodiment, there are the following effects. That is, the air-tight film materials 60 and 160 are provided below the floor surface materials 56 and 156, respectively.
A space for enclosing the air is formed between the 6,156 and the film materials 60, 160, and this space is used as the air conditioning air 32
Ventilation layers 58 and 158 through which A and 32B are distributed and air conditioners 30A and 30B
Can be used as part of the configuration of. Further, since each ventilation layer 58, 158 is formed over the entire floor surface of each air-conditioned space 11-14, by providing an appropriate number of outlets 70, 170 at appropriate locations on each floor surface material 56, 156, the upper layers Air-conditioned space 11
The air conditioning air 32A, 32B can be supplied to the required places of up to 14 as much as necessary, and so-called free access can be realized. For this reason, air conditioning air 32A into each air-conditioned space 11-14,
The distributability of 32B can be improved.

Furthermore, the installation of the membrane materials 60 and 160 can be performed by using the existing building structure, in particular, the structure of the wooden house premised on the traditional natural ventilation of our country, so that the construction work is troublesome. Not surprisingly, it is possible to avoid drastic changes in the building structure. Further, compared with the case where the ducts 910 to 913 shown in FIG. 14 are installed, the space for installing the membrane materials 60 and 160 does not need special space,
The inconvenience of increasing the floor height H1 in FIG. 14 or sacrificing the ceiling height H2 can be eliminated. Further, the film materials 60, 160 are provided below the joists 57, 157 over the entire floor surface of the air-conditioned spaces 11 to 14, and
At the position just below 57,157, the joists 57,157 are bent downward from the lower surface, so that the air-conditioning air 32A, 32B can flow in each ventilation layer 58, 158 in any direction. That is, in the ventilation layer 58 on the first floor, arrows A (longitudinal direction of joist 57) and B (direction orthogonal to joist 57) shown in FIG.
By thus circulating the air conditioning air 32A, the air conditioning air 32A can flow in either of the X and Y directions in FIG. The same applies to the ventilation layer 158 on the second floor. Further, the tack 66 is provided on the peripheral edge portion 61 of the film material 60, whereby the bending of the film material 60 described above can be easily ensured. The same applies to the membrane material 160 on the second floor. The membrane material 60 on the first floor is formed integrally over the entire floor surface of each of the air-conditioned spaces 11 and 12, and the middle portion thereof is sandwiched between the joists 57 and the Daihiki 53 which are substantially orthogonal to each other. Therefore, it is possible to support the film material 60 without using a separate supporting member, while giving the film material 60 an appropriate amount of bending.

The film materials 60 and 160 are airtight,
Around the ventilation layers 58 and 158, there are provided film material retainers 64 and 164 that function as windbreak materials, and inside the partition walls 80, 81, 180, and 181 above the ventilation paths 65 and 165, heat insulation materials that function as windbreak materials. 84 are provided. And each film material
Elastic members 62, 162A, 162B functioning as seal members are provided on the peripheral portions 61, 161A, 161B of the 60, 160 (160A, 160B) as needed. Therefore, by these, each ventilation layer 5
8,158 can be sealed, and the air-conditioning air 32A, 32B sent inside these can be prevented from leaking to the outside.
It is possible to reliably prevent the pressure from decreasing. Furthermore, energy conservation can be realized by ensuring such airtightness, efficient air conditioners 30A and 30B can be configured, and the air conditioning capacity of the air conditioners 30A and 30B can be reduced. The air conditioners 30A and 30B can be made smaller and have smaller capacities to be inexpensive air conditioners 30A and 30B. And since it is possible to easily secure the airtightness by installing the above-mentioned membrane materials 60, 160, etc., the conventional underfloor space 19,
Compared to the case where the entire 20 is used as a ventilation layer, the bottom of the underfloor spaces 19, 20 is covered with concrete, or an airtight seal is provided between the foundation 51 and the base 52 to ensure the airtightness of the underfloor spaces 19, 20. Good air conditioning can be achieved without the need for troublesome construction.

Further, since the space between the membrane material 60,160 and the floor material 56,156 is the ventilation layer 58,158, the air-conditioning air 32A, 32B in each ventilation layer 58,158 is below the membrane material 60,160 by the membrane material 60,160. The air in the space on the side is cut off, and odors, bacteria, etc. under the floor do not flow into the air conditioning spaces 11 to 14 on the floor, and clean and good air conditioning can be performed. Furthermore, compared to the conventional method by installing the ducts 910 to 913 of FIG.
Since the ventilation layers 58 and 158 have a large cross-sectional area and a small airflow velocity, noise can be suppressed, and the possibility of vibration such as in the duct installation method can be eliminated.

Further, the air conditioning air 32A, 32B supplied into each air conditioning space 11-14 is collected in each passage space 15, 16 and returned to each air conditioner 31A, 31B, so that the return ventilation is performed. A circulation path for the air conditioning air 32A, 32B of each air conditioner 30A, 30B can be secured without providing a separate path.
In addition, air-conditioned spaces 11, 12 on the first floor and air-conditioned spaces 13, 14 on the second floor
Since the film material 160 is provided between the
By imparting the above-mentioned heat insulating properties such as heat ray reflectivity and heat transfer blocking property, it is possible to prevent the spread of fire from the first floor to the second floor in the event of a fire.

The floor of the passage space 16 on the second floor and the ceiling of the passage space 15 on the first floor are provided with communication ports 266 and 267, respectively, which are connected so as to be separated from the pit space 18 by a duct 294 having a fan 293 on the way. And this duct 293 allows passage space
16 and the passage space 15 communicate with each other. The fan 293 is provided to forcibly send the air conditioning air 232 from the passage space 16 to the passage space 15. These communication ports 266,26
7, fan 293, duct 294, passage space 16 and passage space
It is not necessary to provide it when 15 and the stairs communicate with each other.

In such a second embodiment, air conditioning of each floor is performed as follows. In the second embodiment, unlike the first embodiment, the air conditioning of the first floor portion and the second floor portion is performed by the common air conditioner 230. In the first-floor portion, first, fresh air-conditioning air 232 that has been subjected to various air-conditioning processes is pressurized and released into the pit space 17 and sent into the ventilation layer 58 through the ventilation path 65. Next, the air-conditioning air 232 in the ventilation layer 58 is supplied to the air-conditioned spaces 11 and 12 on the first floor from the outlets 70 provided appropriately in the floor surface material 56. Thereafter, the air-conditioning air 232 in each air-conditioned space 11, 12 is exhausted to the passage space 15 from the air passages 82, 83 provided in the partition walls 80, 81, and returned to the air conditioner 231 through the suction port 85. Be done.

On the other hand, in the second floor, first, the pressurized air-conditioning air 232 in the pit space 17 is branched from the ventilation passage 65, and is ventilated through the ventilation passage 165 through the inside-wall spaces 280, 281 and the pit space 18.

FIG. 6 shows a part of a building 300 having a floor structure and an air conditioner according to a third embodiment of the present invention. In FIG. 6, the building 300 has substantially the same structure as the building 10 of the first embodiment of FIG. 1 described above, and only the configuration of the air conditioner 330 is different, so the same parts are designated by the same reference numerals. Detailed description is omitted, and only different parts will be described below. In the above-described first embodiment of FIG. 1, each air-conditioned space 11
~ 14 are air conditioners 31A, which are provided in the pit spaces 17 and 18, respectively.
Although air conditioning such as ventilation, cooling and heating (temperature control), dehumidification, and humidification is performed by 31B, in the third embodiment, an air conditioner 331 dedicated to heating such as a hot air fan is provided in the air-conditioned space 11. . The air conditioner 331 can be installed in the other air-conditioned spaces 12 to 14 in the same manner, but the illustration thereof is omitted here. Air conditioner 33
1 is a suction port provided above the air in the air-conditioned space 11
Inhaled from 333 and heated this air internally to
Air-conditioning air 332 is introduced into the ventilation layer 58 from the air supply port 334 passing through
(In the case of the third embodiment, it becomes hot air for heating). Further, in the third embodiment, the ventilation passage 65 (FIG. 1) below the partition wall body 80 is a membrane material retainer.

In such a third embodiment, heating is performed as follows. First, the air-conditioning air 332 heated from the air conditioner 331 is sent into the ventilation layer 58 through the air supply port 334. Next, the air-conditioning air 332 in the ventilation layer 58 is supplied to the air-conditioned space 11 from the outlet 70 that is appropriately provided in the floor surface material 56. After that, the air for air conditioning 332 in the air-conditioned space 11 is sucked into the air conditioner 331 through the suction port 333 of the air conditioner 331,
Here, it is reheated and again fed into the ventilation layer 58 through the air supply port 334.

By removing this, the space in the air-conditioned space 11 can be effectively used. Further, in addition to the supply of the air conditioning air 332 into the air-conditioned space 11 from the blowout port 70 provided in the floor surface material 56, since the air conditioning space 11 is radiated through the floor material 56, floor heating is also performed at the same time. be able to. Therefore, the temperature of the air-conditioning air 332 supplied from the outlet 70 into the air-conditioned space 11 is set to the minimum temperature difference from the room temperature of the air-conditioned space 11, so that comfortable heating can be realized and the heat pump can be used. It is possible to sufficiently heat even with a relatively low temperature heat source.

FIG. 7 shows a schematic structure of a floor structure 450 and a floor heating device 430 according to the fourth embodiment of the present invention. The building 400 having the floor structure 450 and the floor heating device 430 has a structure substantially similar to that of the building 10 of the first embodiment of FIG. 1 described above, and a part of the floor structure 450 and the floor heating device 430. Since only the configuration is different, the same parts are denoted by the same reference numerals and detailed description thereof will be omitted, and only different parts will be described below. In the building 10 of the first embodiment of FIG. 1,
Air-conditioned spaces 11 to 14 are formed on the first and second floors, but in the building 400 of the fourth embodiment, each air-conditioned space is
Heating spaces 411 to 414 are formed at positions 11 to 14 (not shown), and floor heating is performed by a floor heating device 430 using a floor structure 450.

In FIG. 7, the floor structure 450 has substantially the same structure as the floor structure 50 of the first floor portion or the floor structure 150 of the second floor portion of the first embodiment shown in FIG. Here, the first floor portion will be described, the same portions as those of the floor structure 50 of the first embodiment will be denoted by the same reference numerals, and detailed description thereof will be omitted. Only different portions will be described below. The second floor has the same structure as the first floor. The floor structure 450, like the floor structure 50 of the first embodiment, has a base 52 as a peripheral material.
Daihiki 53, which is a material for handing over, has been handed over. Between the upper surface of the base 52 and the Daihiki 53, a joist 57, which is a floor surface support member that supports the floor material 56 of the heating spaces 411, 412, is laid across in a direction substantially orthogonal to the Daihiki 53. Further, a ventilation layer 58 is formed between the membrane material 60 and the floor material 56 sandwiched between the Daihiki 53 and the joist 57. The floor structure 450 differs from the floor structure 50 of the first embodiment in that a bar-shaped partition member 451 for partitioning the inside of the ventilation layer 58 is provided in a portion located directly above the Daihiki 53 and between the joists 57 as shown in FIG.
It is provided on the upper side of the film material 60 along the Daihiki 53 except for the portion where the arrows K1 to K12 inside cross. On the other hand, right below a part of the joists 57, there is provided a bar-shaped partition member 452 that is bridged between the Daihiki 53 or between the Daihiki 53 and the base 52 (a portion indicated by a dotted line in FIG. 7). Membrane material between this partition 452 and joist 57
The film material 60 is sandwiched so that the film material 60 does not bend in this portion. These partition members 451,452 make the ventilation layer 58
The inside is appropriately partitioned in the X and Y directions in the figure to form a predetermined air passage. In addition, the floor structure 450 does not have the one corresponding to the outlet 70 of FIG. 1 that connects the ventilation layer 58 and the heating spaces 411 and 412.

The floor heating device 430 has a heater 431, and is constructed so as to send the heating air 432 into the ventilation layer 58 from the heater 431. The heaters 431 are installed in the heating spaces 411, 412, in the passage space 15 between them, in the underfloor spaces 19, 20 below the heating spaces 411, 412, and in the membrane material.
It may be an appropriate place such as the lower part of the 60, the pit space 17 or the outdoors. The heating air 432 is supplied from the heater 431 into the ventilation layer 58 by appropriately using a wind guide flexible duct depending on the installation position of the heater 431.
The same is true for the return air of the heating air 432 from the ventilation layer 58 to the heater 431. In the lower part of FIG. 7, the heating air 432 in the ventilation layer 58 flows in the X direction above the Daihiki 53 as indicated by arrows K1 to K3, and this flow is indicated by arrows L1 to L4. Divides into a flow in the Y direction in the figure that passes under the joist 57, and then
As shown by arrows K4 to K6, these flows flow on the upper side of the Daihiki 53 in the X direction in FIG. On the other hand, FIG.
In the upper part of the inside, the heating air 432 flows in the X direction in the figure above the large haul 53 as indicated by arrows K7 to K9.
As shown in L5 to L7, the flow branches in the Y direction in the figure that passes under the joist 57, and then these flows merge in the X direction in the figure above the Daihiki 53 as indicated by arrows K10 to K12. It is supposed to do. Further, in the portion M in the figure, the flow of the heating air 432 is blocked by the partitioning material 452, and a floor, for example, a chest of drawers that does not require heating heat supply, should be installed on the floor. You can

The amount of heating air 432 flowing in the portions indicated by arrows L1 to L4 in the figure can be controlled by changing the amount of deflection of the film material 60 in these portions by adjusting the tack 66 and the like. . That is, the heating air 432 is shown in the portion of the arrow L1 in the figure.
If the distribution volume of L is uneven, the arrows L1, L2, L3,
If the amount of bending of the film material 60 is made smaller in the order of L4, a uniform flow of the heating air 432 can be obtained. Arrow L5 ~ in the figure
The same applies to the L7 part. In addition, partition materials 451,45
The installation position of 2 may be an appropriate place as long as the flow of the heating air 432 can be controlled in the ventilation layer 58 in a predetermined direction. It is desirable that the ventilation path in the ventilation layer 58 is formed so that the heating heat is uniformly supplied to the entire floor surface.

In the fourth embodiment, floor heating is performed as follows. First, the heating air 432 is sent from the heater 431 into the ventilation layer 58. Then the ventilation layer 58
The heating air 432 fed into the inside circulates in the ventilation layer 58 as indicated by arrows K1 to K3, L1 to L4, and K4 to K6 in the lower portion in FIG. In the part, arrows K7 to K9,
Like the L5 to L7 and K10 to K12, they circulate in the ventilation layer 58 and flow. At this time, heating heat is supplied from the heating air 432 to the heating spaces 411, 412 via the floor surface material 56. After that, the heating air 432 in the ventilation layer 58 is returned to the heater 431 without being blown out into the heating spaces 411, 412 above the floor material 56.

According to the fourth embodiment described above, except that the heating air 432 circulates only in the ventilation layers 58, 158 and is not blown out to the heating spaces 411-414 above the floor coverings 56, 156, respectively. That is, substantially the same effects as those of the first, second, and third embodiments can be obtained except that indoor ventilation is not performed. In addition, the ventilation layers 58 and 158 are provided in each heating space 411-
Since it is formed over the entire floor surface of 414, heating heat can be uniformly supplied to the entire floor surface. Furthermore, partition members 451 are appropriately installed in the ventilation layers 58 and 158, and membrane members 60 and 1
Since the partition material 452 is properly installed under the 60,
Since the flow of the heating air 432 can be controlled in a predetermined direction in the ventilation layers 58, 158 by these partition members 451 and 452, the heating heat can be more reliably supplied to the entire floor surface. In addition, the heater 431 is connected to each heating space 411 ~
When installed in 414, the heater 431 can be detachable so that it can be removed in the summer and the space in each of the heating spaces 411 to 414 can be effectively used.

The present invention is not limited to the above-described embodiments, but includes other configurations that can achieve the object of the present invention, and the following modifications and the like are also included in the present invention. . That is, in the first floor portion of the first and second embodiments, the ventilation passage 65 formed below the partition walls 80, 81.
The air conditioning air 32A, 232 was sent from the air conditioners 31A, 231 into the ventilation layer 58 by the air conditioners 31A, 231 (see FIGS. 1 and 5). However, as shown in FIG.
A notch 500 that connects the underfloor space 19 with the underfloor space 19 is formed, and a flexible duct 501 for introducing the air conditioning air 32A, 232 from each air conditioner 31A, 231 into the ventilation layer 58 is provided through the notch 500. May be.

Further, in the first and second embodiments, the air conditioners 30A, 30B and 230 are arranged such that the air conditioning air 32A, 32B and 232 are connected to the air conditioners 31A and 31B and 31B through the passage spaces 15 and 16, respectively. It is configured to be returned to the partition 231, but as shown in FIG.
It may be configured such that it is returned from the suction port 510 provided with a filter provided on the side surface of the partition wall body 511 through the wall body space 511 formed inside the partition wall body 80. The same applies to the second floor. In the case of the second embodiment, another partition space 280 for sending the air-conditioning air 232 into the ventilation layer 158 on the second floor is already formed inside the partition wall body 80. In this case, the partition wall body 80 may be provided with a partition to separate the feed wall body space 280 and the return wall body space 511.

Further, as shown in FIG. 9, the pit space 17
The partition plate 515 is used for the upper pit space 512 which is the return pit space and the lower pit space 513 which is the feed pit space.
It may be divided into two parts. In this case, the air conditioner 31A, 231
The air conditioning air 32A, 232 is discharged from the lower pit space 513 from the above-mentioned notch 500 provided on the foundation 51 or the foundation 51.
Air-conditioning air 32A, 232 is sent into the ventilation layer 58 through the air guide flexible duct 514 whose end is fixed to a hole or the like passing through. On the other hand, the air conditioning air 32A, 232 returning from the air conditioning space 11 via the suction port 510 is the upper pit space 512.
From there, it is returned to the air conditioners 31A, 231. By forming the upper pit space 512 and the lower pit space 513 in this way, the return air to the air conditioners 31A and 231 is directly performed from the air conditioned space 11 without passing through the passage space 15, so that it can be used for heating. It is possible to prevent the vertical temperature difference of the passage space 15 from increasing. In particular, since it is not necessary to provide a ventilation path between the passage space 15 and the air-conditioned space 11, it is not possible to look inside the air-conditioned space 11 from the passage space 15, and an excellent configuration can be provided in terms of privacy protection. . Instead of dividing the pit space 17 into upper and lower parts as shown in FIG. 9, it may be divided into left and right parts in the figure by providing a partition plate in the vertical direction, and the air conditioners 31A and 231 are divided. It may be installed on either side of the pit space, and may be installed outdoors if it communicates with these divided pit spaces.
