Abstract

PROBLEM TO BE SOLVED: To provide a new air conditioning system in light of characteristics of a residence area.SOLUTION: In an air conditioning system 120, an air conditioner 140 conditions outdoor air fed from an outdoor air introduction system 150 and the fed air returned from a residence area 210 in an air conditioner room 121, and delivers conditioned-air-conditioner-room indoor air to an underfloor space 111 via a delivery partitioning portion 113. The residence area 210 having a large residence area height because of an opening ceiling form introduces the conditioned-air-conditioner-room indoor air delivered into the underfloor space 111 from a delivery port 115 of a residence floor 112 with the underfloor space 111 used as a flow path, and returns the introduced conditioned-air-conditioner-room indoor air from ceiling 108 into the air conditioner room 121. In other residence areas 211 to 214 having smaller residence area heights and separated from the residence area 210, the conditioned-air-conditioner-room indoor air is introduced from the delivery port 115 of each residence area via ducts 211d to 214d extending from an underfloor-space communication portion 114 to the delivery port 115 of each residence area and an in-duct blower 119 and the introduced conditioned-air-conditioner-room indoor air flows out into the residence area 210.

Description

本発明は、空調システムに関する。   The present invention relates to an air conditioning system.

従来は、住居の居間や台所等の各部屋を個別に空調することが一般的であったが、住居の高気密化や高断熱化が進んだことと相まって、一台の空調機で、住居の各部屋の他、廊下、階段、或いは玄関、トイレ、浴室等の区画された複数の住居域の空調を行うことが提案されている(例えば、特許文献1等)。   Previously, it was common to individually air-condition each room such as the living room and kitchen, but in conjunction with the progress of airtightness and high thermal insulation in the residence, a single air conditioner can be used for housing. It has been proposed to air-condition a plurality of residential areas such as corridors, stairs, entrances, toilets, bathrooms, etc. (for example, Patent Document 1).

特開2011−174674号公報JP 2011-174664 A 特開2012−57880号公報JP 2012-57880 A

区画された複数の住居域は、住居床を隔てて住居の床下空間の上に並んでいるものの、その形状や占有容積は一律ではない。よって、送気能力がほぼ同じ送気口を、住居域の占有容積に応じた個数ずつ各住居域に配置すれば、床下空間を各住居域への空調済み空気の送気領域として利用できる。しかしながら、住居域の占有容積に応じた個数の送気口の設置を図りつつ床下空間を送気領域として利用しても、各住居域における空調の様子に差が生じることが判明した。このため、一台の空調機で複数の住居域の空調を行う空調システムにおいては、住居域の特性を考慮した新たな空調手法が要請されるに到った。この他、空調システムの低コスト化、設置工法の簡便化も要請されている。   The plurality of partitioned residential areas are lined up on the under floor space of the house across the residential floor, but the shape and occupied volume are not uniform. Therefore, if the number of air supply ports having substantially the same air supply capacity is arranged in each residential area by the number corresponding to the occupied volume of the residential area, the underfloor space can be used as an air supply area for conditioned air to each residential area. However, it has been found that even if the underfloor space is used as the air supply area while installing the number of air supply openings according to the occupied volume of the residential area, a difference occurs in the state of air conditioning in each residential area. For this reason, in an air conditioning system that performs air conditioning of a plurality of residential areas with a single air conditioner, a new air conditioning method that takes into account the characteristics of the residential areas has been required. In addition, there is a demand for cost reduction of the air conditioning system and simplification of the installation method.

上記した課題の少なくとも一部を達成するために、本発明は、以下の形態として実施することができる。   In order to achieve at least a part of the problems described above, the present invention can be implemented as the following forms.

(1)本発明の一形態によれば、空調システムが提供される。この空調システムは、区画された複数の住居域を有する住居の空調システムであって、住居外からの外気の送気と、前記複数の住居域に送気済み空気のリターンとを受ける空調機室と、該空調機室に設置され、空調室内の空調を行う空調機と、前記空調機にて空調済みの空調室内空気を、前記空調機室から前記住居の床下まで延びる送気用区画部を経て、前記空調機室から床下空間に送り出す空調空気送出機構とを備える。前記複数の住居域のうち、住居域の占有容積が他の前記住居域より大きい大容積住居域は、前記床下空間に前記空調空気送出機構により送り出された前記空調室内空気を、前記大容積住居域の住居床に設けた複数の送気口から導き入れ、該導き入れた前記空調室内空気を前記空調機室にリターンさせ、前記複数の住居域のうち、前記大容積住居域より前記占有容積が小さく前記大容積住居域と区画された他の住居域は、前記空調空気送出機構により送り出される前記空調室内空気を、前記他の住居域に設けた送気口まで延びるダクトと該ダクト内での送気を図る送風機とを介して前記送気口から導き入れ、該導き入れた前記空調室内空気を前記大容積住居域に流出させる。上記形態の空調システムでは、住居域の占有容積が大きい大容積住居域と、当該住居域より占有容積が小さく且つ大容積住居域と区画された他の住居域とで、空調空気送出機構から送り出される空調室内空気の住居域内への導き方を異なるものとした。よって、次の利点がある。   (1) According to one aspect of the present invention, an air conditioning system is provided. This air conditioning system is a residential air conditioning system having a plurality of partitioned residential areas, and receives an air supply from outside the house and a return of air supplied to the plurality of residential areas. An air conditioner that is installed in the air conditioner room and performs air conditioning in the air conditioner room, and an air supply compartment that extends the air-conditioned room air that has been conditioned by the air conditioner from the air conditioner room to the floor of the dwelling. Then, an air-conditioning air delivery mechanism for delivering the air-conditioner room to the under-floor space is provided. Among the plurality of residential areas, a large-volume residential area in which the occupied volume of the residential area is larger than the other residential areas is the air-conditioned room air sent out by the air-conditioned air delivery mechanism to the underfloor space. Led from a plurality of air supply ports provided in the residential floor of the area, the introduced air-conditioned room air is returned to the air conditioner room, and the occupied volume from the large-volume residential area among the plurality of residential areas The other residential area which is divided from the large-capacity residential area is a duct which extends the air-conditioned room air sent out by the air-conditioned air delivery mechanism to an air inlet provided in the other residential area. Then, the air is introduced from the air supply port via a blower for supplying air, and the introduced air-conditioned room air is discharged to the large-volume residential area. In the air conditioning system of the above form, the large-capacity residential area where the occupied volume of the residential area is large and the other residential areas which are smaller than the residential area and partitioned from the large-capacity residential area are sent from the air-conditioned air delivery mechanism. The method of guiding the air-conditioning indoor air into the residential area is different. Therefore, there are the following advantages.

大容積住居域には、床下空間に送り出された空調室内空気を、住居床に設けた複数の送気口から導き入れる。つまり、空調室内空気は、床下空間そのものが流路として利用されて、複数の送気口から大容積住居域に導入される。この大容積住居域は、導き入れた空調室内空気を空調機室にリターンさせているので、住居域内における空気の流れが促進され、床下空間に送り出された空調室内空気は、住居床に設けた複数の送気口から特段の抵抗を受けることなく円滑に大容積住居域に導入される。このことは、床下空間そのものを流路として利用した大容積住居域への空調室内空気の導入が進むことを意味する。その一方、仮に、占有容積が小さい住居域(以下、小容量住居域と称する)への空調室内空気の導入を床下空間そのものを流路として利用して行うと、床下空間そのものを流路として利用した大容積住居域への空調室内空気の導入が進む分だけ、小容量住居域への空調室内空気の導入に支障が起きる。また、小容量住居域に床下空間そのものを経て送気口から導入した空調室内空気を大容積住居域に流出させる場合、吸気口からの空気導入と大容積住居域への空気流出とには抵抗が掛かる。こうしたことから、小容量住居域への空調室内空気の導入が進まず、小容量住居域での空調に支障が起き得る。   In the large-capacity residential area, air-conditioned room air sent to the under-floor space is introduced from a plurality of air supply ports provided on the residential floor. In other words, the air-conditioned room air is introduced into the large-capacity residential area from a plurality of air supply ports, using the underfloor space itself as a flow path. In this large-scale residential area, the introduced air-conditioned room air is returned to the air-conditioner room, so the air flow in the residential area is promoted, and the air-conditioned room air sent to the under-floor space is provided on the residential floor. It is smoothly introduced into a large-volume residential area without receiving special resistance from a plurality of air supply ports. This means that the introduction of air-conditioned room air into a large-capacity residential area using the underfloor space itself as a flow path proceeds. On the other hand, if air-conditioning room air is introduced into a residential area with a small occupied volume (hereinafter referred to as a small-capacity residential area) using the underfloor space itself as a flow path, the underfloor space itself is used as the flow path. As the introduction of air-conditioned room air into the large-capacity residential area advances, the introduction of air-conditioned room air into the small-capacity residential area will be hindered. In addition, when the air-conditioning room air introduced from the air inlet through the underfloor space itself into the small-capacity residential area is discharged to the large-capacity residential area, it is resistant to air introduction from the inlet and the air outflow to the large-capacity residential area. It takes. For these reasons, the introduction of air-conditioned room air into small-capacity residential areas does not progress, and air conditioning in the small-capacity residential areas may be hindered.

ところが、上記形態の空調システムは、小容量住居域には、小容量住居域の送気口まで延びるダクトにて、空調室内空気を独立して導くと共に、該ダクト内での送気を図る送風機にてダクトでの通気を促進させる。このため、小容量住居域への送気口からの空調室内空気の導入を、大容積住居域への空調室内空気の導入の影響や空気導入・流出に伴う抵抗を受けないようにして実行できる。よって、上記形態の空調システムによれば、住居域の特性を考慮して各住居域への空調室内空気の導入を図るので、占有容積の大小に拘わらず、各住居域を1台の空調機で支障なく空調できる。また、大容積住居域への空調室内空気の導入については、床下空間そのものを流路として利用するので、ダクトや送風機が不要となり、低コスト化、或いはダクト設置の省略を経た工法の簡略化を図ることも可能となる。   However, the air conditioning system of the above-described form is a fan that guides air in an air-conditioned room to a small-capacity residential area independently through a duct that extends to the air-feeding port of the small-capacity residential area. To promote ventilation in the duct. For this reason, the introduction of air-conditioned indoor air from the air inlet into a small-capacity residential area can be executed without receiving the influence of the introduction of air-conditioned indoor air into a large-capacity residential area and resistance due to air introduction / outflow. . Therefore, according to the air conditioning system of the above aspect, air conditioning indoor air is introduced into each residential area in consideration of the characteristics of the residential area, so that each residential area is provided with one air conditioner regardless of the size of the occupied space. Can be air-conditioned without any problems. In addition, for the introduction of air-conditioned indoor air into large-capacity residential areas, the underfloor space itself is used as a flow path, eliminating the need for ducts and blowers, reducing costs, and simplifying the construction method after omitting the installation of ducts. It is also possible to plan.

(2)上記した形態の空調システムにおいて、前記他の住居域(小容量住居域)は、前記送気口を前記他の住居域の住居床に備え、前記送気用区画部と前記床下空間との繋ぎ箇所から前記送気口まで延びる前記ダクトを介して前記前記空調室内空気を前記送気口から導き入れるようにできる。こうすれば、小容量住居域への空調室内空気の導入を図るダクトを床下空間に設置できるので、床下空間の有効利用を図ることができる。   (2) In the above-described air conditioning system, the other residential area (small-capacity residential area) includes the air supply port on a residential floor of the other residential area, and the air supply partition section and the underfloor space The air-conditioned room air can be introduced from the air supply port through the duct extending from the connection point to the air supply port. In this way, a duct for introducing air-conditioned room air into a small-capacity residential area can be installed in the underfloor space, so that the underfloor space can be effectively used.

(3)上記したいずれかの形態の空調システムにおいて、大容積住居域は、住居域天井が前記空調機室の近傍に位置して、前記床下空間と隔てる住居床から前記天井までの住居域高さが高くされているようにできる。一般に、住居高さが高い住居域は、高天井故に住居域の占有容積が大きくなり、床下空間そのものを流路として利用した住居域(大容積住居域)への空調室内空気の導入がより進むが、この影響を受けることなく、小容量住居域にも空調室内空気を支障なく導入できるので、住居高さの高低に拘わらず、各住居域を1台の空調機で支障なく空調できる。   (3) In any one of the above-described air conditioning systems, the large-capacity residential area is configured such that the residential area ceiling is located in the vicinity of the air conditioner room and is separated from the underfloor space from the residential floor to the ceiling. Can be as high as possible. In general, in residential areas with high residential height, the occupied volume of the residential area increases because of the high ceiling, and air-conditioning room air is introduced more into the residential area (large-capacity residential area) that uses the underfloor space itself as a flow path. However, without being affected by this, air-conditioning indoor air can be introduced into a small-capacity residential area without hindrance, so that each dwelling area can be air-conditioned with one air conditioner regardless of the height of the dwelling.

(4)上記したいずれかの形態の空調システムにおいて、前記送気用区画部は、前記大容積住居域に隣接して前記空調機室から前記住居の床下まで延びるようにできる。こうすれば、大容積住居域と住居床を隔てた床下空間が送気用区画部に隣接することから、大容積住居域の下方の床下空間を有効に流路として利用でき、大容積住居域に空調室内空気を高い効率で導入できる。   (4) In any one of the above-described air conditioning systems, the air supply section may extend from the air conditioner room to the floor under the residence adjacent to the large-volume residential area. In this way, since the underfloor space separating the large volume residential area and the residential floor is adjacent to the air supply section, the underfloor space below the large volume residential area can be effectively used as a flow path, and the large volume residential area Air conditioning room air can be introduced with high efficiency.

以下、本発明の実施の形態について、図面に基づき説明する。図1は本発明の実施形態としての住居100の概略構成を模式的に縦断面視して示す説明図、図2は住居100における1階と2階の部屋割りの概要を平面視しつつ空気導出入と合わせて示す説明図である。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view schematically showing a schematic configuration of a residence 100 as an embodiment of the present invention in a vertical sectional view, and FIG. 2 is a plan view showing an outline of the room layout of the first floor and the second floor in the residence 100. It is explanatory drawing shown together with derivation | leading-in / out.

図示するように、本実施例の住居100は、基礎101に建てられた高気密・高断熱の2階建て住居であって、各階に複数の住居域を区画して有し、各住居域を後述の空調システム120にて空調する。住居域の割り当ては、各住居ごとに個別に設定でき、本実施形態では、例えば次のようにした。住居100は、1階に住居域210〜214を備え、2階に住居域221〜223を備える。1階の住居域210〜214は、基礎101に形成される床下空間111と住居床112を隔てて、当該床下空間の上に並んでいる。住居域210は、図2(B)に示すように、玄関領域210a、1階廊下領域210bと階段ステップSが配列済みの階段領域210sを含み、1階廊下領域210bと階段領域210sの一部領域において、天井が2階天井まで届くいわゆる吹き抜け形態を採る。よって、住居域210は、住居床112から天井までの住居域高さが1階の他の住居域211〜214より高く、その天井108を隔てて空調機室121の下方まで延びる高天井住居域となっている。こうした高天井住居域の住居域210を、1階部分にリビングやキッチンを階段領域210sと共に有するいわゆる共有住居域とするようにしてもよい。住居域211〜213は、居間や客間等として利用可能であり、住居域214は、その平面視位置の関係から、浴室や洗面所等を含むものとしてもよい。これら住居域210〜214は、住居構成基材としての住居内外壁および各住居域の天井にて区画されている。住居域211〜213は居間や客間等として利用され、住居域210は上記の各領域を含んだ上で吹き抜け形態を採ることから、住居域210は、その占有容積が他の住居域である住居域211〜213より大きくされている。   As shown in the figure, the residence 100 of this embodiment is a high-air-tight and highly insulated two-story residence built on the foundation 101, and has a plurality of residential areas on each floor, and each residential area is Air conditioning is performed by an air conditioning system 120 described later. The allocation of the residence area can be set individually for each residence. In the present embodiment, for example, the following is performed. The dwelling 100 includes dwelling areas 210 to 214 on the first floor, and dwelling areas 221 to 223 on the second floor. The residential areas 210 to 214 on the first floor are arranged above the underfloor space with the underfloor space 111 and the dwelling floor 112 formed on the foundation 101 being separated. As shown in FIG. 2B, the residential area 210 includes an entrance area 210a, a first-floor corridor area 210b, and a staircase area 210s in which stair steps S are arranged, and a part of the first-floor corridor area 210b and the staircase area 210s. In the area, a so-called atrium structure is adopted in which the ceiling reaches the ceiling on the second floor. Therefore, the residential area 210 has a higher residential area height from the residential floor 112 to the ceiling than the other residential areas 211 to 214 on the first floor, and extends to the lower part of the air conditioner room 121 across the ceiling 108. It has become. Such a high-ceiling residential area 210 may be a so-called shared residential area having a living room and a kitchen together with a staircase area 210s on the first floor. The residential areas 211 to 213 can be used as a living room, a guest room, and the like, and the residential area 214 may include a bathroom, a washroom, and the like from the relationship of the plan view position. These residential areas 210 to 214 are partitioned by residential inner and outer walls as the housing constituent base material and ceilings of the respective residential areas. Since the residential areas 211 to 213 are used as living rooms, guest rooms, and the like, and the residential area 210 includes the above-described areas, the residential area 210 has a volume occupied by another residential area. It is made larger than the area | region 211-213.

2階の住居域221〜223は、子供部屋や寝室等として利用可能であり、階段領域210sと2階廊下領域220bを含む2階部分の住居域210と並んでいる(図2(A)参照)。これら住居域221〜223にあっても、住居構成基材としての住居内外壁および各住居域の天井にて区画されている。なお、例えば、1階廊下領域210bの奥側(紙面右側)を、トイレや浴室としたり、2階廊下領域220bの奥側をトイレとしたりできる。   The second-floor residential areas 221 to 223 can be used as child rooms, bedrooms, and the like, and are aligned with the second-floor residential area 210 including the staircase area 210s and the second-floor corridor area 220b (see FIG. 2A). ). Even in these residential areas 221 to 223, they are partitioned by the inner and outer walls of the house as the housing constituent base material and the ceiling of each residential area. For example, the back side (right side of the drawing) of the first floor corridor area 210b can be a toilet or a bathroom, and the back side of the second floor corridor area 220b can be a toilet.

住居100は、屋根109と2階の天井108の間の屋根裏110に、空調システム120を有する。この空調システム120は、空調機室121と、空調機140と、外気導入系150とを有する。空調機室121は、既述した住居域210等の各住居域とは別に形成され、その内壁を断熱材にて被覆し、後述の空調機140にて空調された空気の熱を外部に漏らさないようにしている。空調機室121は、室内に仕切プレート122を有する。この仕切プレート122は、空調機室121の内部空間を、吸気側と空調側に区分する。また、空調システム120は、空調機室121から床下空間111まで延びる送気用区画部113を備える。この送気用区画部113は、その上端側で空調機140が設置された空調機室121の空調側域に連通し、下端側では、床下空間連通箇所114にて床下空間111と連通し、住居域210に隣接して空調機室121から床下空間111まで延びる。そして、空調システム120は、空調機室121にて空調機140により空調済みの空調室内空気CAを、送気用区画部113の上端側の複数台のモーター駆動の空気送風機123aと、送気用区画部113の下端側の複数台のモーター駆動の空気送風機123bとにより、送気用区画部113を経て空調機室121から床下空間111に送風する。つまり、送気用区画部113は、その上下端の複数台の空気送風機123aと空気送風機123bと協働して、本発明における空調空気送出機構を構成する。なお、空調システム120のメンテナンスは、屋根裏110に続く収納タイプの階段が用いられる。この場合、空調システム120の空調機室121は、屋根裏110に限らず、送気用区画部113を確保できる住居100の適宜な箇所に設置できる。   The dwelling 100 has an air conditioning system 120 in the attic 110 between the roof 109 and the ceiling 108 on the second floor. The air conditioning system 120 includes an air conditioner room 121, an air conditioner 140, and an outside air introduction system 150. The air conditioner room 121 is formed separately from each residential area such as the residential area 210 described above, and the inner wall thereof is covered with a heat insulating material, and the heat of air conditioned by the air conditioner 140 described later is leaked to the outside. I am trying not to. The air conditioner room 121 has a partition plate 122 in the room. The partition plate 122 divides the internal space of the air conditioner room 121 into an intake side and an air conditioning side. In addition, the air conditioning system 120 includes an air supply partition 113 that extends from the air conditioner room 121 to the underfloor space 111. This air supply section 113 communicates with the air conditioning side area of the air conditioner room 121 where the air conditioner 140 is installed at the upper end side, and communicates with the underfloor space 111 at the underfloor space communication point 114 on the lower end side. It extends from the air conditioner room 121 to the underfloor space 111 adjacent to the residential area 210. The air-conditioning system 120 supplies air-conditioned room air CA that has been air-conditioned by the air-conditioner 140 in the air-conditioner room 121 to a plurality of motor-driven air blowers 123a on the upper end side of the air-feeding section 113 and air-feeding air. The air is blown from the air conditioner chamber 121 to the underfloor space 111 through the air supply partition portion 113 by a plurality of motor-driven air blowers 123b on the lower end side of the partition portion 113. That is, the air supply partition section 113 constitutes an air-conditioned air delivery mechanism according to the present invention in cooperation with the plurality of air blowers 123a and 123b at the upper and lower ends. For the maintenance of the air conditioning system 120, a storage-type staircase following the attic 110 is used. In this case, the air conditioner room 121 of the air conditioning system 120 is not limited to the attic 110 but can be installed at an appropriate location of the residence 100 where the air supply section 113 can be secured.

空調機室121は、後述の外気導入系150による住居外からの外気の送気と、住居域210に後述するように送気済み空気(空調済み空調室内空気CA)のリターンとを、仕切プレート122で仕切られた吸気側に受ける。空調機140は、空調機室121の仕切プレート122を乗り越えてきた空気、即ち外気導入系150から導入されて除塵済みの外気と後述するようにリターンした空調済み空調室内空気CAとの混合気を目標温度に空調する市販のエアコンであり、空調した空気(空調済み空調室内空気CA)を吹き出す。空調機140の室外機(図示略)は、住居100の外に設置されている。外気導入系150は、住居外壁に設置済みの外気吸入部151から空調機室121の接続部153までの外気導入管154に、熱交換器155と、エアフィルター156を有する。熱交換器155は、後述の排気管157を流れる空気と外気導入管154を通過する空気の熱交換を行い、空調機140による空調のエネルギーロスの低減を図る。ここで、空調の目標温度と、総風量について、簡単に説明する。   The air conditioner room 121 divides the outside air by the outside air introduction system 150, which will be described later, and the return of the air that has been supplied to the residential area 210 (air-conditioned indoor air CA) as will be described later. Received on the intake side partitioned by 122. The air conditioner 140 obtains a mixture of the air that has passed over the partition plate 122 of the air conditioner room 121, that is, the outside air introduced from the outside air introduction system 150 and dust-removed, and the air-conditioned room air CA that has been returned as described later. It is a commercially available air conditioner that air-conditions to a target temperature, and blows out air-conditioned air (air-conditioned air-conditioned room air CA). An outdoor unit (not shown) of the air conditioner 140 is installed outside the residence 100. The outside air introduction system 150 includes a heat exchanger 155 and an air filter 156 in the outside air introduction pipe 154 from the outside air suction part 151 installed on the outer wall of the residence to the connection part 153 of the air conditioner room 121. The heat exchanger 155 exchanges heat between air flowing through an exhaust pipe 157 (to be described later) and air passing through the outside air introduction pipe 154 to reduce the energy loss of air conditioning by the air conditioner 140. Here, the air conditioning target temperature and the total air volume will be briefly described.

空調システム120は、特開2011−174674号公報で提案された空調システムとほぼ同じスペックとできる。つまり、空調機140は、空調機室121の室内の目標温度と、空調対象である上記した住居空間の目標温度とが、冷房空調の際には、摂氏5℃以内の温度差、暖房空調の際には摂氏10℃以内の温度差で、空調機室121の室内の空気を空調する。そして、空調システム120は、空気送風機123aにより、空調済み空調室内空気CAを100〜5,000m3/hの流量で送気用区画部113に送り出し、ほぼ同流量のまま、空気送風機123bにより床下空間連通箇所114から床下空間111に送り出す。このように大流量での空調済み空気の送風により、各住居域の温度を適度に維持して快適性を確保している。 The air conditioning system 120 can have substantially the same specifications as the air conditioning system proposed in Japanese Patent Application Laid-Open No. 2011-174673. That is, the air conditioner 140 has a temperature difference within 5 degrees Celsius between the target temperature of the air conditioner room 121 and the target temperature of the above-described residential space that is the air conditioning target, In some cases, the air in the air conditioner room 121 is air-conditioned with a temperature difference within 10 degrees Celsius. The air-conditioning system 120 sends the air-conditioned air-conditioned room air CA to the air-feeding section 113 at a flow rate of 100 to 5,000 m 3 / h by the air blower 123a, and keeps the floor under the floor by the air blower 123b with almost the same flow rate. It sends out from the space communication place 114 to the underfloor space 111. In this way, by blowing air-conditioned air at a large flow rate, the temperature of each residential area is appropriately maintained to ensure comfort.

次に、各階の住居域への空調済み空調室内空気CAの導入構成と空調機室121へのリターン構成、並びに各住居域での空気導入・排出の様子について説明する。   Next, the introduction configuration of the air-conditioned air-conditioned room air CA to the residential area of each floor, the return structure to the air conditioner room 121, and the state of air introduction / discharge in each residential area will be described.

1階の住居域210は、住居床112に、送気口115とモーター駆動の吸引送風機116とを備え、その天井108に、リターン口117とモーター駆動の吸引送風機118とを備える。送気口115と吸引送風機116とは対となって住居床112に複数対設置され、送気口115は、吸引送風機116が床下空間111から吸引した空気、即ち、送気用区画部113を経て空調機室121から床下空間111(詳しくは、住居域210の下方を占める床下空間111a)に送り出された空調済み空調室内空気CAを、住居域210の内部に導き入れる。リターン口117は、住居域210の天井108を貫いて空調機室121の内部、詳しくは仕切プレート122で区分された空調機室121の吸気側まで延び、吸引送風機118が住居域210から吸引した空気、即ち、送気口115から住居域210に導入された空調室内空気CAを、空調機室121の吸気側に強制的にリターンさせる。こうしてリターンされたリターン空気RAは、外気導入系150からの外気と共に、既述したように空調機140による空調に処される。本実施形態では、住居域210の占有容積が大きいことを考慮して、住居域210に送気口115と吸引送風機116とを4対設置したが、送気口115の送風能力によっては、住居域210の占有容積を考慮して、5対以上としたり、2〜3対としてもよい。また、床下空間111aには空気送風機123bにて空調済み空調室内空気CAが送り出されるので、この空調済み空調室内空気CAは、それぞれの送気口115から住居域210に流入可能となる。よって、複数の送気口115のうちのいくつかについて、或いは全部について吸引送風機116を省略してもよい。   The residential area 210 on the first floor includes an air supply port 115 and a motor-driven suction fan 116 on the residential floor 112, and a return port 117 and a motor-driven suction fan 118 on its ceiling 108. A plurality of air supply openings 115 and suction blowers 116 are installed on the residential floor 112 as a pair. The air supply openings 115 define the air sucked from the underfloor space 111 by the suction blowers 116, that is, the air supply partition 113. The conditioned air-conditioned room air CA sent from the air conditioner room 121 to the under-floor space 111 (specifically, the under-floor space 111 a occupying the lower side of the residential area 210) is introduced into the residential area 210. The return port 117 extends through the ceiling 108 of the residential area 210 to the inside of the air conditioner room 121, specifically to the intake side of the air conditioner room 121 divided by the partition plate 122, and the suction blower 118 sucks from the residential area 210. The air, that is, the air-conditioned room air CA introduced into the residential area 210 from the air supply port 115 is forcibly returned to the intake side of the air-conditioner room 121. The return air RA thus returned is subjected to air conditioning by the air conditioner 140 as described above together with the outside air from the outside air introduction system 150. In the present embodiment, considering that the occupied volume of the residential area 210 is large, four pairs of the air inlet 115 and the suction blower 116 are installed in the residential area 210. Considering the occupied volume of the area 210, it may be 5 pairs or more, or 2 to 3 pairs. In addition, since the air-conditioned indoor air CA is sent out to the underfloor space 111a by the air blower 123b, the air-conditioned air-conditioned indoor air CA can flow into the residential area 210 from each air supply port 115. Therefore, the suction blower 116 may be omitted for some or all of the plurality of air supply ports 115.

1階の住居域211〜214の各住居域は、各住居域が占める住居床112に、送気口115を備え、住居域210との区画箇所である住居内壁に、流出口130とこれに対となるモーター駆動の吸引送風機131とを備える。住居域211〜214の各住居域は住居域210に比べて占有容積が小さいことから、送気口115については、一つとされている。この他、住居域211〜214の各住居域は、住居床112の下方の床下空間111に、ダクト211d〜214dとモーター駆動のダクト内送風機119を備える。ダクト211d〜214dは、断熱性を備え、送気用区画部113と住居域210の下方を占める床下空間111aとの床下空間連通箇所114を基点とし、当該連通箇所から住居域211〜214の各住居域の下方を占める床下空間111b〜111eまで延び、床下空間連通箇所114において、空気送風機123bと接続され、各住居域では、送気口115に接続される。本実施形態では、ダクト213dをダクト212dから分岐して住居域212の送気口115まで延ばしたが、このダクト213dについても、独立に床下空間連通箇所114から送気口115まで延ばすようにしてもよい。   Each of the residential areas 211 to 214 on the first floor is provided with an air inlet 115 on the residential floor 112 occupied by each residential area, and on the inner wall of the residential area 210 and the outlet 130 and A motor-driven suction blower 131 is provided. Since each of the residential areas 211 to 214 has a smaller occupied volume than the residential area 210, the air inlet 115 is set to one. In addition, each of the residential areas 211 to 214 includes ducts 211 d to 214 d and a motor-driven in-duct fan 119 in the underfloor space 111 below the residential floor 112. The ducts 211d to 214d are provided with heat insulation properties, and are based on an underfloor space communication point 114 between the air supply section 113 and the underfloor space 111a that occupies the lower side of the residential area 210, and each of the residential areas 211 to 214 from the communication point. It extends to underfloor spaces 111b to 111e occupying the lower part of the residential area, and is connected to the air blower 123b at the underfloor space communication point 114, and is connected to the air supply port 115 in each residential area. In this embodiment, the duct 213d is branched from the duct 212d and extends to the air inlet 115 of the residential area 212. However, the duct 213d is also extended independently from the underfloor space communication point 114 to the air inlet 115. Also good.

ダクト内送風機119は、送気口115の下方側においてダクト内に配設され、空気送風機123bと相まってダクト211d〜214d内での送気を図る。従って、住居域211〜214の各住居域は、住居域210の下方を占める床下空間111aに送気用区画部113を経て送り出された空調済み空調室内空気CAを、各住居域に該当するダクト211d〜214dと各ダクトのダクト内送風機119とを介して送気口115から導き入れ、導き入れた空調済み空調室内空気CAを、吸引送風機131にて流出口130から住居域210に流出する。なお、ダクト211d〜214dとダクト内送風機119とを介した空調済み空調室内空気CAの導入に際しては、床下空間連通箇所114における空気送風機123bも駆動するが、ダクト内送風機119にて空調済み空調室内空気CAの導入が支障なく行われれば、ダクト211d〜214dの基点側の空気送風機123bを省略してもよい。この逆に、ダクト211d〜214dの基点側の空気送風機123bにて空調済み空調室内空気CAの導入が支障なく行われれば、送気口115の側のダクト内送風機119を省略してもよい。また、ダクト内送風機119により送気口115から住居域211〜214の各住居域に空調済み空調室内空気CAが導入されていることから、住居域210への空気流出を図る吸引送風機131については、省略してもよい。   The in-duct air blower 119 is disposed in the duct below the air supply port 115, and works with the air blower 123b to supply air in the ducts 211d to 214d. Accordingly, each of the residential areas 211 to 214 includes the air-conditioned air-conditioned indoor air CA sent to the under-floor space 111a occupying the lower part of the residential area 210 via the air supply partition 113, and the duct corresponding to each residential area. The air-conditioned air-conditioned room air CA introduced through 211d to 214d and the in-duct fan 119 of each duct is introduced from the outlet 130 to the residential area 210 by the suction fan 131. In introducing air-conditioned air-conditioned room air CA through the ducts 211d to 214d and the blower 119 in the duct, the air blower 123b in the underfloor space communication point 114 is also driven. If the introduction of the air CA is performed without hindrance, the air blower 123b on the base point side of the ducts 211d to 214d may be omitted. On the contrary, if the air blower 123b on the base point side of the ducts 211d to 214d can introduce the air-conditioned indoor air CA without any trouble, the blower 119 in the duct on the air supply port 115 side may be omitted. Moreover, since air-conditioned air-conditioned indoor air CA has been introduced into the residential areas 211 to 214 from the air supply port 115 by the blower 119 in the duct, the suction blower 131 that attempts air outflow to the residential area 210 is as follows. , May be omitted.

2階の住居域221〜223の各住居域は、各住居域が占める2階床231に、送気口115とこれに対となる吸引送風機116とを備え、2階床下空間232に導入された空調済み空調室内空気CAを、吸引送風機116にて送気口115から導き入れる。住居域221は、その天井108に排気口170とこれに対となるモーター駆動の吸引送風機172とを備え、住居域221に導入された空調済み空調室内空気CAを、吸引送風機172にて排気口170から外気導入系150の排気管157に排気する。住居域222〜223にあっては、2階部分における住居域210との区画箇所である住居内壁に、流出口130とこれに対となるモーター駆動の吸引送風機131とを備え、上記の各住居域に導入された空調済み空調室内空気CAを、住居域210に流出させる。2階床下空間232への空調済み空調室内空気CAの導入は種々の手法で達成でき、例えば、空調機室121が有する一つの空気送風機123aから2階床下空間232まで、或いは、送気用区画部113から2階床下空間232までダクトを延ばし、このダクトを介して2階床下空間232に空調済み空調室内空気CAを導き、その空調済み空調室内空気CAを送気口115から住居域221〜223に導入できる。また、空調機室121が有する一つの空気送風機123a或いは送気用区画部113から2階床下空間232までダクトを延ばし、ダクトをそれぞれの住居域の送気口115に繋いでも良い。この他、1階の住居域211にも、その天井に流出口130と吸引送風機131とを設け、住居域211から2階床下空間232に空調済み空調室内空気CAを導入してもよい。   Each of the residential areas 221 to 223 on the second floor includes an air inlet 115 and a suction blower 116 paired therewith on the second floor 231 occupied by each residential area. The air-conditioned indoor air CA that has been conditioned is introduced from the air inlet 115 by the suction fan 116. The residential area 221 includes an exhaust port 170 on the ceiling 108 and a motor-driven suction blower 172 that is paired with the exhaust port 170, and the air-conditioned indoor air CA introduced into the residential area 221 is exhausted by the suction fan 172. The air is exhausted from 170 to the exhaust pipe 157 of the outside air introduction system 150. In the residential areas 222 to 223, the housing inner wall, which is a partition with the residential area 210 on the second floor, is provided with an outlet 130 and a motor-driven suction blower 131 paired therewith, The air-conditioned indoor air CA introduced into the area is discharged to the residential area 210. Introduction of the conditioned air-conditioned room air CA into the second floor underfloor space 232 can be achieved by various methods, for example, from one air blower 123a of the air conditioner room 121 to the second floor underfloor space 232, or an air supply section. A duct is extended from the section 113 to the second floor underfloor space 232, and the conditioned air-conditioned room air CA is guided to the second-floor underfloor space 232 through the duct, and the conditioned air-conditioned room air CA is sent from the air inlet 115 to the residential areas 221 to 221. 223. In addition, a duct may be extended from one air blower 123a or the air supply section 113 included in the air conditioner room 121 to the second-floor space 232, and the duct may be connected to the air supply port 115 of each residential area. In addition, the outlet area 130 and the suction fan 131 may be provided on the ceiling of the residential area 211 on the first floor, and the conditioned air-conditioned room air CA may be introduced from the residential area 211 to the second floor underfloor space 232.

以上説明したように、本実施例の住居100が備える空調システム120では、住居仕様によって吹き抜け形態とされたために住居床112から天井108までの住居域高さが高く占有容積も大きい住居域210と、この住居域210に並んで区画された1階の住居域であって住居域210より占有容積の小さい住居域211〜214とで、床下空間111に送り出された空調室内空気CAの住居域内への導き方を異なるものとした。まず、住居域210については、空調機室121から送気用区画部113を経て床下空間111aに送り出された空調済み空調室内空気CAを、住居域210の下方の床下空間111aそのものを流路として利用して、住居床112の複数の送気口115から導き入れる。住居域210は、吹き抜け形態故に住居域高さが高く占有容積も大きいものの、導き入れた空調室内空気CAを天井108のリターン口117から吸引送風機118にて強制的に空調機室121にリターンさせている。このため、吹き抜け形態の住居域210では、住居床112の側から天井108の側への空気の流れが促進されるので、床下空間111aに送り出された空調済み空調室内空気CAは、それぞれの送気口115から特段の抵抗を受けることなく円滑に高天井住居域に導入される。つまり、床下空間111aそのものを流路として利用した住居域210への空調室内空気CAの導入が進む。しかも、送気口115と対となる吸引送風機116により、住居域210への空調室内空気CAの導入はより一層進むことになる。   As described above, in the air conditioning system 120 included in the residence 100 according to the present embodiment, the living area 210 has a high residential area height from the residential floor 112 to the ceiling 108 and has a large occupied volume because of the aerial form according to the residential specifications. In the living area of the air-conditioned room air CA sent out to the underfloor space 111 in the first-floor residential area divided alongside the residential area 210 and having a smaller occupied volume than the residential area 210 The way of guiding was different. First, for the residential area 210, the air-conditioned air-conditioned room air CA sent from the air conditioner room 121 to the under-floor space 111a through the air-supplying section 113 is used as a flow path with the under-floor space 111a itself below the residential area 210 as a flow path. It uses and guides from the plurality of air supply openings 115 of the residence floor 112. Although the residential area 210 has a high residential area height and a large occupied volume because of the atrium structure, the introduced air conditioning room air CA is forcibly returned to the air conditioner room 121 from the return port 117 of the ceiling 108 by the suction fan 118. ing. For this reason, since the air flow from the residential floor 112 side to the ceiling 108 side is promoted in the colonnade-shaped residential area 210, the conditioned air-conditioned indoor air CA sent to the underfloor space 111a is supplied to the respective floors. It is smoothly introduced into the high ceiling dwelling area without receiving any special resistance from the air vent 115. That is, the introduction of the air-conditioned room air CA into the residential area 210 using the underfloor space 111a itself as a flow path proceeds. Moreover, the introduction of the air-conditioned indoor air CA into the residential area 210 is further advanced by the suction blower 116 paired with the air supply port 115.

これに対し、住居域210に並んで区画された占有容積の小さい住居域211〜214については、床下空間111と送気用区画部113との床下空間連通箇所114から住居域211〜214の各住居域の送気口115まで延びるダクト211d〜214dにて、空調室内空気CAを独立して導くと共に、ダクト内送風機119と空気送風機123bとにより、或いは一方の空気送風機により、ダクト通気を促進させる。よって、本実施形態の空調システム120によれば、次の利点がある。   On the other hand, for the small-occupied residential areas 211 to 214 partitioned side by side in the residential area 210, each of the residential areas 211 to 214 from the underfloor space communication point 114 between the underfloor space 111 and the air supply partition section 113. In the ducts 211d to 214d extending to the air inlet 115 in the residential area, the air-conditioning room air CA is guided independently, and the duct ventilation is promoted by the in-duct air blower 119 and the air blower 123b or by one air blower. . Therefore, the air conditioning system 120 of the present embodiment has the following advantages.

仮に、住居域210に並んで区画された占有容積の小さい住居域211〜214への空調室内空気CAの導入を、住居域211〜214の下方の床下空間111b〜111eを流路として利用して行うと、床下空間111aそのものを流路として利用した住居域210への空調室内空気CAの導入が送気用区画部113の側で先に進む分だけ、住居域211〜214への空調室内空気CAの導入に支障が起きる。また、住居域211〜214にその下方の床下空間111b〜111eそのものを経て送気口から導入した空調室内空気CAを住居域210に流出口130から流出させる場合、送気口115からの空気導入とアンダーカットなどの流出口130から住居域210への空気流出とには抵抗が掛かる。こうしたことから、住居域211〜214への空調室内空気CAの導入が進まず、住居域211〜214での空調に支障が起き得る。ところが、本実施形態の空調システム120は、既述したように住居域211〜214への空調室内空気CAの導入にダクト211d〜214dとダクト内送風機119とを用いるので、住居域211〜214への送気口115からの空調室内空気CAの導入を、住居域210への空調室内空気CAの導入の影響や空気導入・流出に伴う抵抗を受けないで実行できる。よって、本実施形態の空調システム120によれば、住居域の特性を考慮して各住居域への空調室内空気CAの導入に支障を来さないので、占有容積の大小に拘わらず、各住居域を1台の空調機140で支障なく空調できる。また、住居域210への空調室内空気CAの導入については、床下空間111aそのものを流路として利用するので、ダクトや送風機が不要となり、低コスト化、或いはダクト設置の省略を経た工法の簡略化を図ることができる。   Temporarily, the introduction of the air-conditioning indoor air CA into the small-occupied residential areas 211 to 214 partitioned alongside the residential area 210 is performed using the underfloor spaces 111b to 111e below the residential areas 211 to 214 as flow paths. Then, the air-conditioned indoor air to the residential areas 211 to 214 is equivalent to the amount that the introduction of the air-conditioned indoor air CA into the residential area 210 using the underfloor space 111a itself as a flow path proceeds on the air supply section 113 side. This will hinder the introduction of CA. In addition, when the air-conditioning indoor air CA introduced from the air supply port into the residential areas 211 to 214 through the underfloor spaces 111b to 111e itself is discharged from the outlet 130 to the residential area 210, air is introduced from the air supply opening 115. Resistance is applied to the outflow of air from the outlet 130 to the residential area 210 such as undercut. For these reasons, the introduction of air-conditioning indoor air CA into the residential areas 211 to 214 does not proceed, and air conditioning in the residential areas 211 to 214 may be hindered. However, since the air conditioning system 120 of this embodiment uses the ducts 211d to 214d and the blower 119 in the duct to introduce the air conditioning indoor air CA into the residential areas 211 to 214 as described above, the air conditioning system 120 to the residential areas 211 to 214 is used. The air-conditioning room air CA can be introduced from the air supply port 115 without receiving the influence of the introduction of the air-conditioning room air CA into the residential area 210 and the resistance due to air introduction / outflow. Therefore, according to the air conditioning system 120 of the present embodiment, the introduction of the air-conditioning indoor air CA into each residential area is not considered in consideration of the characteristics of the residential area. The area can be air-conditioned with one air conditioner 140 without any trouble. In addition, for the introduction of the air-conditioned indoor air CA into the residential area 210, the underfloor space 111a itself is used as a flow path, so that a duct and a blower are unnecessary, and the construction method is simplified through cost reduction or omission of the duct installation. Can be achieved.

本実施形態の住居100では、住居域210を吹き抜け形態としたために、住居域210の天井108が空調機室121の近傍に位置するので、リターン口117と吸引送風機118により空調機室121へのリターン空気RAの流入は進み、住居域210における住居床112の側から天井108の側への空気の流れはより促進される。このため、床下空間111aそのものを流路として利用した住居域210への空調室内空気CAの導入がより進むが、この影響を受けることなく、住居域211〜214には、ダクト211d〜214dとダクト内送風機119とにより支障なく空調室内空気CAを導入できる。よって、本実施形態の空調システム120によれば、住居高さの高低に拘わらず、各住居域を1台の空調機140で支障なく空調できる。   In the residence 100 of the present embodiment, since the residential area 210 is in a blow-off form, the ceiling 108 of the residential area 210 is located in the vicinity of the air conditioner room 121, so that the return port 117 and the suction blower 118 are connected to the air conditioner room 121. The inflow of the return air RA progresses, and the air flow from the residential floor 112 side to the ceiling 108 side in the residential area 210 is further promoted. For this reason, the introduction of the air-conditioning indoor air CA to the residential area 210 using the underfloor space 111a itself as a flow path further proceeds, but without being affected by this, the residential areas 211 to 214 have ducts 211d to 214d and a duct. The air blower indoor air CA can be introduced without any trouble by the inner blower 119. Therefore, according to the air conditioning system 120 of the present embodiment, each residential area can be air-conditioned with no trouble by the single air conditioner 140 regardless of the height of the residence.

ここで、本実施形態の空調システム120による空気導入の様子を、換気回路網計算手法を用いた解析結果と関連付けて説明する。換気回路網計算手法は、空気送気の際の圧力抵抗を電気回路の抵抗とし、風量を電流値と置き換えて計算算出する手法として確立されている。この換気回路網計算手法にて、図2の住居域210における送気口115から空気吹出量と住居域211における送気口115からの空気吹出量を計算した。換気回路網計算を行うに当たり、送気口115→住居域210→リターン口117の順に空気が流れる際の抵抗と、送気口115→住居域211→流出口130→住居域210→リターン口117の順に空気が流れる際の抵抗とを換気回路網計算に組み込んだ。そして、住居域211に、ダクト211dを用いないで床下空間111bを経て送気口115から送気を行った場合と、ダクト211dを用いて送気口115から送気を行った場合とについて、換気回路網計算を行って空気吹出量を計算した。住居域210については、四つの送気口115のそれぞれからの空気吹出量を計算した。その結果、住居域211にダクト211dを用いないで床下空間111bを経て送気口115から送気を行った場合の住居域211の送気口115からの空気吹出量は、38.30m3/hであり、この場合の住居域210のそれぞれの送気口115からの空気吹出量は、240.3m3/hであった。その一方、住居域211にダクト211dを用いて送気口115から送気を行った場合の住居域211の送気口115からの空気吹出量は、200m3/hであり、この場合の住居域210のそれぞれの送気口115からの空気吹出量についても、200m3/hであった。この結果から、本実施形態の空調システム120によれば、住居高さの高低や容積の大小に拘わらず、各住居域を1台の空調機140で支障なく空調できることに加え、住居高さの高低や容積の大小に拘わらず、各住居域に1台の空調機140で均一な吹出風量で空調室内空気CA導き入れることができると言える。このことは、住居高さの高低や容積の大小に拘わらず、各住居域に1台の空調機140で意図した吹出風量で空調室内空気CA導き入れることができることを意味する。 Here, the state of air introduction by the air conditioning system 120 of the present embodiment will be described in association with the analysis result using the ventilation network calculation method. The ventilation network calculation method is established as a method for calculating and calculating by replacing the pressure resistance at the time of air supply with the resistance of the electric circuit and replacing the air volume with the current value. With this ventilation network calculation method, the amount of air blown from the air inlet 115 in the residential area 210 of FIG. 2 and the amount of air blown from the air inlet 115 in the residential area 211 were calculated. In calculating the ventilation network, the resistance when air flows in the order of the air inlet 115 → the residential area 210 → the return outlet 117 and the air inlet 115 → the residential area 211 → the outlet 130 → the residential area 210 → the return outlet 117 The resistance at the time of air flow was incorporated into the ventilation network calculation. And about the case where air is supplied from the air inlet 115 via the underfloor space 111b to the residential area 211 without using the duct 211d, and the case where air is supplied from the air outlet 115 using the duct 211d. Ventilation network calculation was performed to calculate the air blowing rate. For the residential area 210, the amount of air blown from each of the four air inlets 115 was calculated. As a result, when air is supplied from the air inlet 115 via the underfloor space 111b without using the duct 211d in the residential area 211, the amount of air blown from the air outlet 115 of the residential area 211 is 38.30 m 3 / h. In this case, the amount of air blown from each air inlet 115 of the residential area 210 was 240.3 m 3 / h. On the other hand, the amount of air blown from the air inlet 115 of the residential area 211 when air is supplied from the air outlet 115 using the duct 211d to the residential area 211 is 200 m 3 / h. The amount of air blown from each air supply port 115 in the area 210 was also 200 m 3 / h. From this result, according to the air conditioning system 120 of this embodiment, in addition to being able to air-condition each residential area with a single air conditioner 140 regardless of the height of the house and the size of the house, Regardless of the height and volume, it can be said that the air-conditioning indoor air CA can be introduced into each residential area with a single blown air amount by one air conditioner 140. This means that the air-conditioning room air CA can be introduced into each residential area with the amount of blown air intended by one air conditioner 140 regardless of the height of the house and the size of the volume.

本実施形態の空調システム120では、送気用区画部113を、住居域210に隣接して空調機室121から床下空間111まで延びるようにしたので、住居域210と住居床112を隔てた床下空間111aと送気用区画部113とを隣接させる。よって、本実施形態の空調システム120によれば、送気用区画部113から住居域210の下方の床下空間111aに速やかに空調室内空気CAを送り出して、この床下空間111aを有効且つ即座に流路として利用することで、住居域210に空調室内空気CAを高い効率で導入できる。   In the air conditioning system 120 of the present embodiment, the air supply section 113 extends from the air conditioner room 121 to the underfloor space 111 adjacent to the residential area 210, so that the floor below the residential area 210 and the residential floor 112 is separated. The space 111a and the air supply section 113 are adjacent to each other. Therefore, according to the air conditioning system 120 of the present embodiment, the air-conditioning room air CA is quickly sent from the air supply partition 113 to the underfloor space 111a below the residential area 210, and the underfloor space 111a flows effectively and immediately. By using it as a road, the air-conditioned room air CA can be introduced into the residential area 210 with high efficiency.
