本建具の使用態様としては、夏期において室外から室内に空気を流す場合(図1参照)、夏期において室内から室外に空気を流す場合(図27参照)、冬期において室外から室内に空気を流す場合、冬期において室内から室外に空気を流す場合の4通りのパターンがあり、以下に説明するようにそれら4通りのパターンのいずれの場合も、冷房負荷又は暖房負荷を抑える働きがある。この点は、第1実施形態だけでなく、後述する第2実施形態以降の他の全ての実施形態についても同様である。
As shown in FIG. 1, this fitting includes an outdoor ventilation section 11 provided across the upper frame 4 and the upper stile 7, a ventilation path 60 provided across the lower stile 8 and the lower frame 5, and an upper stile 7. Air flows from the outdoors into the room through the indoor ventilation section 12 provided across the upper stile 4 (the arrows in the figure indicate air flow), or air flows from the room to the outdoors as shown in FIG. At that time, air flows through the intermediate layer 10 in a detour along the inner surface of the outer glass 1 and the outer surface of the inner glass 2, thereby reducing the amount of heat entering and exiting through the window while providing ventilation and reducing the heating and cooling load. It can be suppressed.
This fitting can be used to flow air from the outdoors into the room in the summer (see Figure 1), to flow air from the room to the outdoors in the summer (see Figure 27), and to flow air from the outdoors into the room in the winter. There are four patterns for flowing air from indoors to outdoors in winter, and as explained below, all of these four patterns have the effect of suppressing the cooling load or heating load. This point applies not only to the first embodiment but also to all other embodiments after the second embodiment described later.

まず、夏期において室外から室内に空気を流す場合について説明する。この場合、換気扇により室内を負圧に調整する。これにより、図28(a)に示すように、室外の温かい空気(外気)が、室外側通気部11より中間層10に吸い込まれ、整流体65にガイドされて外側ガラス1の内側面に沿って下向きに流れる。このように、外側ガラス1の内側面に沿って室外の温かい空気を下向きに流すことで、外側ガラス1の室外側と室内側の空気の温度差が小さくなり、これにより外側ガラスの室外側から室内側に貫流する熱を減らすことができる(請求項1)。その後、空気は中間層10の下端部付近で折り返し(より詳細には、下框8を通って下枠5内で折り返す。図1参照。)、内側ガラス2の外側面に沿って上向きに流れ、この間に内側ガラス2の室内側から室外側に逃げる冷熱を空気で回収する(請求項2)。冷熱を回収することで空気は冷やされ、室内側通気部12より室内に流入する。
このように本建具は、夏期において室外から室内に空気が流れることで、外側ガラス1側で室外側から室内側への貫流熱が減り、内側ガラス2側で室内側から室外側に逃げる冷熱を回収するので、非常に高い断熱性能が得られ、冷房負荷を抑えることができる。
First, a case will be described in which air is flowed indoors from outdoors during the summer. In this case, adjust the indoor pressure to negative using a ventilation fan. As a result, as shown in FIG. 28(a), warm outdoor air (outdoor air) is sucked into the intermediate layer 10 from the outdoor side ventilation section 11, guided by the flow regulator 65, and moved along the inner surface of the outer glass 1. flows downward. In this way, by flowing the warm outdoor air downward along the inner surface of the outer glass 1, the temperature difference between the air on the outdoor side and the indoor side of the outer glass 1 is reduced, and as a result, the temperature difference between the air on the outdoor side and the indoor side of the outer glass 1 is Heat flowing into the room can be reduced (Claim 1). Thereafter, the air turns around near the lower end of the intermediate layer 10 (more specifically, passes through the lower stile 8 and turns back inside the lower frame 5, see FIG. 1), and flows upward along the outer surface of the inner glass 2. During this time, the cold heat escaping from the indoor side of the inner glass 2 to the outdoor side is recovered by air (Claim 2). The air is cooled by recovering cold heat and flows into the room from the indoor ventilation section 12.
In this way, in the summer, when air flows from the outdoors into the room, this fitting reduces the amount of heat passing through from the outside to the indoor side on the outside glass 1 side, and reduces the cold heat escaping from the indoor side to the outside on the inside glass 2 side. Since it is recovered, extremely high insulation performance can be obtained and the cooling load can be reduced.

次に、夏期において室内から室外に空気を流す場合について説明する。この場合、換気扇により室内を正圧に調整する。これにより、図28(b)に示すように、室内の涼しい空気(内気)が室内側通気部12より中間層10に流れ、整流体65にガイドされて内側ガラス2の室外側面に沿って下向きに流れる。このように、室内の空気を内側ガラス2の外側面に沿って下向きに流すことで、内側ガラス2の室内側と室側の空気の温度差が小さくなり、これにより内側ガラス2の室内側から室外側に貫流する冷熱を減らすことができる。その後、空気は中間層10の端部付近で折り返し、外側ガラス1の内側面に沿って上昇し、この間に外側ガラス1の室外側から外側ガラス1の室内側に入ってくる貫流熱と日射熱を空気の流れによって回収する。その後、空気は室外側通気部11より室外に流出し、これにより回収した貫流熱と日射熱を空気で室外に排出する。空気が室外側通気部11を通過する際、上框7と上枠4を伝って室内に入ってくる熱を空気の流れによって回収し、室外に捨てることができる。
このように本建具は、夏期において室内から室外に空気が流れることで、外側ガラス1側で室外側から室内側への貫流熱と日射熱を排出し、内側ガラス2側で室内側から室外側への貫流冷熱が減るため、非常に高い断熱性能が得られ、冷房負荷を抑えることができる。
Next, a case will be described in which air is flowed from indoors to outdoors in summer. In this case, use a ventilation fan to maintain positive pressure in the room. As a result, as shown in FIG. 28(b), indoor cool air (indoor air) flows from the indoor ventilation section 12 to the intermediate layer 10, is guided by the flow regulator 65, and is directed downward along the outdoor side of the inner glass 2. flows to In this way, by causing the indoor air to flow downward along the outer surface of the inner glass 2, the temperature difference between the air on the indoor side and the outdoor side of the inner glass 2 becomes smaller. It is possible to reduce the amount of cold heat that flows from the outside to the outside. After that, the air turns around near the end of the intermediate layer 10 and rises along the inner surface of the outer glass 1, and during this time, the through-flow heat and solar radiation enter from the outdoor side of the outer glass 1 to the indoor side of the outer glass 1. is collected by air flow. Thereafter, the air flows out of the room through the outdoor ventilation section 11, thereby discharging the collected through-flow heat and solar heat to the outside of the room . When the air passes through the outdoor ventilation part 11, the heat that enters the room through the upper stile 7 and the upper frame 4 can be recovered by the air flow and disposed of to the outdoors.
In this way, this fitting allows air to flow from indoors to outdoors in the summer, discharging through-flow heat and solar heat from the outdoor side to the indoor side on the outer glass 1 side, and discharging heat from the indoor side to the outdoor side on the inner glass 2 side. This reduces the amount of cold heat flowing through the system, resulting in extremely high insulation performance and reducing the cooling load.

次に、冬期において室外から室内に空気を流す場合について説明する。この場合、換気扇により室内を負圧に調整する。これにより、図29(a)に示すように、室外の冷たい空気(外気)が、室外側通気部11より中間層10に吸い込まれ、整流体65にガイドされて外側ガラス1の内側面に沿って下向きに流れる。このように、外側ガラス1の内側面に沿って室外の冷たい空気を下向きに流すことで、外側ガラス1の室外側と室内側の空気の温度差が小さくなり、外側ガラス1の室外側から室内側に貫流する冷熱を減らすことができる。また、外側ガラス1の内側面に沿って空気が流れることで、日射熱の室内への取得を増加させることができる(請求項5)。その後、空気は中間層10の下端部付近で折り返し、内側ガラス2から室内の熱が伝わることで暖められ、内側ガラス2の室外側面に沿って上昇し、この間に内側ガラス2の室内側から室外側に逃げる熱を空気の流れによって回収する(請求項6)。そうして暖められた空気を室内に取り入れることで、回収した熱を室内に戻すことができる。
このように本建具は、冬期において室外から室内に空気が流れることで、外側ガラス1側で室外側から室内側に貫流する冷熱が減ると共に日射熱の取得が増加し、内側ガラス2側で室内側から室外側に逃げる熱を回収するので、非常に高い断熱性能が得られ、暖房負荷を抑えることができる。また、外気を暖めて室内に採り込めるので、室内に居る人が冷たい風を感じることがない。
Next, a case will be described in which air is flowed indoors from outdoors during the winter season. In this case, adjust the indoor pressure to negative using a ventilation fan. As a result, as shown in FIG. 29(a), cold outdoor air (outdoor air) is sucked into the intermediate layer 10 from the outdoor side ventilation section 11, guided by the flow regulator 65, and moved along the inner surface of the outer glass 1. flows downward. In this way, by flowing the cold outdoor air downward along the inner surface of the outer glass 1, the temperature difference between the outdoor side and the indoor side of the outer glass 1 becomes smaller, and the air flows from the outdoor side of the outer glass 1 to the indoor side. It can reduce the amount of cold that flows inside. Moreover, by allowing air to flow along the inner surface of the outer glass 1, it is possible to increase the amount of solar heat absorbed into the room (claim 5). After that, the air turns around near the lower end of the intermediate layer 10, is warmed by the indoor heat being transmitted from the inner glass 2, and rises along the outdoor side of the inner glass 2, and during this time, from the indoor side of the inner glass 2 to the indoor Heat escaping to the outside is recovered by air flow (Claim 6). By bringing the warmed air into the room, the recovered heat can be returned to the room.
In this way, with this fitting, when air flows from the outdoors into the room in winter, the cold heat flowing from the outdoor side to the indoor side on the outside glass 1 side is reduced, and the acquisition of solar heat increases, while the indoor glass on the inside glass 2 side Since the heat escaping from the inside to the outside is recovered, extremely high insulation performance can be achieved and heating loads can be reduced. In addition, since the outside air can be warmed and brought indoors, people staying indoors will not feel the cold wind.

次に、冬期において室内から室外に空気を流す場合について説明する。この場合、換気扇により室内を正圧に調整する。これにより、図29(b)に示すように、室内の温かい空気(内気)が室内側通気部12より中間層10に流れ、整流体65にガイドされて内側ガラス2の室外側面に沿って下向きに流れる。このように、室内の空気を内側ガラス2の外側面に沿って下向きに流すことで、内側ガラス2の室内側と室外側の空気の温度差が小さくなり、これにより内側ガラスの室内側から室外側に貫流する熱を減らすことができる。その後、空気は中間層10の端部付近で折り返し、外側ガラス1の内側面に沿って上昇し、この間に外側ガラス1の室外側から外側ガラスの室内側に貫流する冷熱を空気で回収し、室外側通気部11より空気が室外に流出することで、回収した冷熱を室外に排出する。
このように本建具は、冬期において室内から室外に空気が流れることで、外側ガラス1側で室外側から室内側への貫流冷熱を回収して室外に排出し、内側ガラス2側で室内側から室外側への貫流熱が減るため、非常に高い断熱性能が得られ、暖房負荷を抑えることができる。
Next, a case will be described in which air is flowed from indoors to outdoors in winter. In this case, use a ventilation fan to maintain positive pressure in the room. As a result, as shown in FIG. 29(b), warm indoor air (indoor air) flows from the indoor ventilation section 12 to the intermediate layer 10, is guided by the flow regulator 65, and is directed downward along the outdoor side of the inner glass 2. flows to In this way, by causing the indoor air to flow downward along the outer surface of the inner glass 2, the temperature difference between the indoor side and the outdoor side of the inner glass 2 is reduced, and this causes the air to flow from the indoor side of the inner glass 2 to the indoor side. It can reduce the heat flowing to the outside. After that, the air turns around near the end of the intermediate layer 10 and rises along the inner surface of the outer glass 1, and during this time, the cold energy flowing through from the outdoor side of the outer glass 1 to the indoor side of the outer glass is recovered by the air, As the air flows out of the outdoor ventilation section 11, the collected cold heat is discharged to the outside .
In this way, when air flows from indoors to outdoors in winter, this fitting collects the cold heat flowing from the outdoor side to the indoor side on the outside glass 1 side and discharges it to the outdoors, and on the inside glass 2 side, it collects the cold heat flowing from the outside to the indoor side and discharges it to the outside. Since the amount of heat passing through to the outdoor side is reduced, extremely high insulation performance can be achieved, and heating loads can be reduced.

中間層10に設けられる整流体65は、図1に示すような上下方向の長さが短いものであってもよいが、図28,29に示すように、中間層10の上端から下部に亘って長く設けてあってもよい。そうすることで、外側ガラス1の内側面に沿う空気の流れと内側ガラス2の外側面に沿う空気の流れがぶつかり合うのを防ぎ、外側ガラス1の内側面と内側ガラス2の外側面に沿うように迂回する空気の流れが良好に得られ、上記した各効果が確実に得られる。整流体65を長く設けることで、夏期においては日射熱の取得を抑制でき、冬期においては日射熱の取得を増加させることができる。そのような長い整流体65としては、ブラインド(ハニカムブラインドを含む)、ロールスクリーン等を用いることができる。 The flow regulator 65 provided in the intermediate layer 10 may have a short length in the vertical direction as shown in FIG. 1, but may have a short length in the vertical direction as shown in FIGS. It may be provided for a long time. By doing so, the air flow along the inner surface of the outer glass 1 and the air flow along the outer surface of the inner glass 2 are prevented from colliding with each other, and the air flow along the inner surface of the outer glass 1 and the outer surface of the inner glass 2 is prevented from colliding with each other. Thus, a good detour air flow can be obtained, and each of the above-mentioned effects can be reliably obtained. By providing the rectifier 65 for a long time, it is possible to suppress the acquisition of solar heat in the summer and increase the acquisition of solar heat in the winter. As such a long flow regulator 65, a blind (including a honeycomb blind), a roll screen, etc. can be used.

図3は、本発明の建具(単体サッシ)の第2実施形態を示している。図3に示すように、上枠4は、第1実施形態と同様に上枠本体20と上枠カバー21とからなり、上枠本体20は室外側の中空部25より内周側の室外側壁に通気孔27rが設けてあり、上枠カバー21は、上下方向の中間部に設けた横壁30に、室外に通じる通気孔27eが下向きに開口して設けてある。
上框7は、第1実施形態と同様に、室外側部材7aの室外側部33及び室内側部34の中空部36,37の外周側壁と内周側壁に通気孔27f,27g,27h,27iが設けてあり、加えて室内側部材7bの中空部81より外周側の室内側壁に通気孔27sが設けてある。
FIG. 3 shows a second embodiment of the fitting (single sash) of the present invention. As shown in FIG. 3, the upper frame 4 is made up of an upper frame body 20 and an upper frame cover 21, as in the first embodiment, and the upper frame body 20 is an outdoor side wall on the inner circumferential side from the outdoor hollow part 25. A ventilation hole 27r is provided in the upper frame cover 21, and a ventilation hole 27e communicating with the outdoors is provided in a horizontal wall 30 provided in the middle part in the vertical direction and opens downward.
Similar to the first embodiment, the upper stile 7 has ventilation holes 27f, 27g, 27h, 27i in the outer circumferential side wall and inner circumferential side wall of the hollow parts 36, 37 of the outdoor side part 33 and the indoor side part 34 of the outdoor side member 7a. In addition, a ventilation hole 27s is provided in the indoor wall on the outer peripheral side of the hollow portion 81 of the indoor member 7b.

本建具(単体サッシ)は、外周側フレーム(上枠)4と内周側フレーム(上框)7に上記のように通気孔27r,27e,27f,27g,27h,27i,27sを形成したことで、室外空間から中間層10に連通する室外側通気部11を、外周側フレーム4に設けた通気孔27e,27rから外周側フレーム4と内周側フレーム7の隙間(空間S)を通り内周側フレーム7を貫通して中間層10に通じるように設けてあり、中間層10から室内空間に連通する室内側通気部12を、中間層10から内周側フレーム7を貫通し内周側フレーム7と外周側フレーム4の隙間(空間S)を通り外周側フレーム4又は内周側フレーム7の室内側壁に設けた通気孔27sから室内空間に通じるように設けてある。
このように室外側通気部11と室内側通気部12を設けた場合も、内周側フレーム7より外周側で空気が出入りするため、空気の流れる経路が長くなるので、断熱性能が向上する。また、第1実施形態と異なり外周側フレーム4の中空部25,26に空気を通さないため、通気孔の数を少なくできる。
外周側フレーム4に通気孔27e,27rを設ける代わりに、外周側フレーム4と内周側フレーム7間のタイト材19aの一部に切り欠きを設け、内周側フレーム7に通気孔27sを設ける代わりに、外周側フレーム4と内周側フレーム7間のタイト材19bの一部に切り欠きを設け、そのタイト材19a,19bの切り欠きから外周側フレーム4と内周側フレーム7の間の空間Sに空気が出入りするようにすることもできる。そうすることで、通気孔の数をさらに少なくできる。
This fitting (single sash) has ventilation holes 27r, 27e, 27f, 27g, 27h, 27i, and 27s formed in the outer frame (upper frame) 4 and inner frame (upper stile) 7 as described above. The outdoor ventilation section 11 that communicates with the intermediate layer 10 from the outdoor space is connected to the interior through the ventilation holes 27e and 27r provided in the outer frame 4 through the gap (space S) between the outer frame 4 and the inner frame 7. The indoor ventilation section 12 is provided so as to pass through the circumferential frame 7 and communicate with the intermediate layer 10, and communicate from the intermediate layer 10 to the indoor space. The ventilation hole 27s provided in the indoor side wall of the outer frame 4 or the inner frame 7 passes through a gap (space S) between the frame 7 and the outer frame 4 and communicates with the indoor space.
Even when the outdoor ventilation section 11 and the indoor ventilation section 12 are provided in this manner, air enters and exits on the outer peripheral side of the inner peripheral frame 7, so the path through which the air flows becomes longer, so that the heat insulation performance is improved. Further, unlike the first embodiment, since air is not passed through the hollow portions 25 and 26 of the outer frame 4, the number of ventilation holes can be reduced.
Instead of providing the ventilation holes 27e and 27r in the outer frame 4, a notch is provided in a part of the tight material 19a between the outer frame 4 and the inner frame 7, and a ventilation hole 27s is provided in the inner frame 7. Instead, a notch is provided in a part of the tight material 19b between the outer frame 4 and the inner frame 7, and the gap between the outer frame 4 and the inner frame 7 is cut out from the cutout of the tight material 19a, 19b. It is also possible to allow air to enter and exit the space S. By doing so, the number of ventilation holes can be further reduced.

また、第2実施形態の建具(単体サッシ)は、下框8には第1実施形態と同様に通気孔27n,27o,27p,27qが設けてあるが、下枠5には通気孔を設けておらず、下枠5と下框8との間の隙間(空間S)で空気の流れを折り返している。
このように、外周側フレーム(下枠)5と内周側フレーム(下框)8との間で空気の流れを折り返す場合も、内周側フレーム8より外周側で空気の流れを折り返すことになるので、空気の流れる経路が長くなり、その結果、断熱性能が向上する。外周側フレーム(下枠)5に通気孔の加工が不要なため、コストを削減できる。
In addition, in the fittings (single sash) of the second embodiment, the lower frame 8 is provided with ventilation holes 27n, 27o, 27p, and 27q as in the first embodiment, but the lower frame 5 is provided with ventilation holes. The airflow is turned around in the gap (space S) between the lower frame 5 and the lower stile 8.
In this way, even when the air flow is turned back between the outer frame (lower frame) 5 and the inner frame (lower stile) 8, the air flow is turned back on the outer side from the inner frame 8. As a result, the path through which the air flows becomes longer, and as a result, the insulation performance improves. Since there is no need to process ventilation holes in the outer frame (lower frame) 5, costs can be reduced.

Similar to the first embodiment, in the fittings (single sash) of this embodiment, air flows around the intermediate layer 10 along the inner surface of the outer glass 1 and the outer surface of the inner glass 2 (see FIG. (Refer to 20), in the winter, the heat that escapes from indoors to the outdoors is recovered by airflow and returned indoors, and in the summer, the heat that enters the room from the outdoors is recovered by airflow and disposed of outside. By reducing the amount of heat entering and exiting through windows, it is possible to reduce heating and cooling loads.
Since the outdoor side ventilation section 11 and the indoor side ventilation section 12 are constructed only from the upper frame 4, and the air flow is turned back at the end of the intermediate layer 10, less processing is required for the ventilation holes, reducing costs. can.

図22は、本発明の建具(単体サッシ)の第13実施形態を示しており、第12実施形態とは上枠の構造が異なっている。
上枠4は、上枠本体20と、上枠本体20の室外側に取付けた上枠カバー21と、上枠本体20の室内側に取付けた樹脂カバー94とを有している。上枠本体20は、アルミ形材よりなる室外側部22と室内側部23とを樹脂製の断熱ブリッジ24で連結して構成してあり、室外側部22と室内側部23はそれぞれ中空部25,26を有している。室外側の中空部25の室外側壁と内周側壁とに通気孔95a,95bを形成して室外側通気部11が形成してあり、室内側の中空部26の内周側壁と室内側壁とに通気孔95c,95dを形成して室内側通気部12を形成してあるのは、第12実施形態と同じである。
上枠4は、断熱ブリッジ24の内周側に整流体65が設けてある。整流体65は、下方に向かって室外側に傾斜した平らな板状となっている。
FIG. 22 shows a thirteenth embodiment of the fitting (single sash) of the present invention, which differs from the twelfth embodiment in the structure of the upper frame.
The upper frame 4 includes an upper frame body 20, an upper frame cover 21 attached to the outdoor side of the upper frame body 20, and a resin cover 94 attached to the indoor side of the upper frame body 20. The upper frame main body 20 is constructed by connecting an outdoor side part 22 and an indoor side part 23 made of aluminum shapes with a heat insulating bridge 24 made of resin, and each of the outdoor side part 22 and the indoor side part 23 has a hollow part. 25, 26. The outdoor side ventilation part 11 is formed by forming ventilation holes 95a and 95b in the outdoor side wall and the inner peripheral side wall of the indoor side hollow part 25, and the indoor side wall and the indoor side wall of the indoor hollow part 26. It is the same as the twelfth embodiment that the indoor ventilation section 12 is formed by forming ventilation holes 95c and 95d.
In the upper frame 4, a flow regulator 65 is provided on the inner peripheral side of the heat insulating bridge 24. The flow regulator 65 has a flat plate shape that is inclined downward toward the outdoor side.

本実施形態の建具(単体サッシ)は、上フレーム(上枠)4は室外側及び室内側に中空部25,26を有し、室外側の中空部25と室内側の中空部26とが断熱ブリッジ24により熱的に遮断されていることで、冬期において室内側の中空部26に室外の冷気が伝わらないため、室内の熱により暖められて内側ガラス2の外側面に沿って上昇した空気が、室内側の中空部26を通過する際に冷やされるのを防止し、回収した熱を確実に室内に戻すことができるので、空気の流れる方向と逆方向の熱輸送が妨げられることによる断熱効果が確実に発揮される。
また、本実施形態の建具(単体サッシ)は、整流体65が上フレーム4の熱伝導遮断位置(断熱ブリッジ24)の内周側に設けてあると共に、整流体65の先端を外側ガラス1側に向けてあるため、整流体65の結露が抑制されるとともに、空気の流れを外側ガラス1の内側面に沿わせられる。
In the fittings (single sash) of this embodiment, the upper frame (upper frame) 4 has hollow parts 25 and 26 on the outdoor side and the indoor side, and the hollow part 25 on the outdoor side and the hollow part 26 on the indoor side are insulated. Due to the thermal isolation provided by the bridge 24, the cold air from outside does not reach the hollow part 26 on the indoor side in winter, so the air warmed by the heat inside the room and rising along the outer surface of the inner glass 2 is prevented. This prevents the heat from being cooled when it passes through the hollow part 26 on the indoor side, and ensures that the recovered heat is returned indoors, resulting in a heat insulation effect by preventing heat transport in the opposite direction to the direction in which air flows. is definitely demonstrated.
In addition, in the fittings (single sash) of this embodiment, the flow regulator 65 is provided on the inner peripheral side of the heat conduction cutoff position (insulation bridge 24) of the upper frame 4, and the tip of the flow regulator 65 is placed on the outer glass 1 side. Since it is oriented toward the outer glass 1, dew condensation of the fluid regulating fluid 65 is suppressed, and the air flow can be made to follow the inner surface of the outer glass 1.

室外側の中空部25と室内側の中空部26とを熱的に遮断した上フレーム4の構造としては、上記のアルミ製の室外側部22と室内側部23とを断熱ブリッジ24で連結した構造の他、室外側がアルミ形材で形成され、室内側が樹脂形材で形成されたアルミ+樹脂の複合構造や、全体が樹脂で形成したものであってもよい。 The structure of the upper frame 4 that thermally isolates the hollow part 25 on the outdoor side and the hollow part 26 on the indoor side is such that the outdoor side part 22 and the indoor side part 23 made of aluminum are connected by a heat insulating bridge 24. In addition to the structure, it may be a composite structure of aluminum and resin in which the outdoor side is formed of an aluminum profile and the indoor side is formed of a resin profile, or the entire structure may be made of resin.

図23は、第13実施形態の変形例を示しており、図22のものとは、整流体65の形状が異なっている。図23(a)記載のものは、整流体65が室外側に向けて円弧状に曲がった形になっている。図23(b)記載のものは、整流体65が中間部から室外側に向けて曲がっている。整流体65をこのような形状とした場合も、図22の整流体65と同様に、空気の流れを外側ガラス1の内側面に沿わせられる。 FIG. 23 shows a modification of the thirteenth embodiment, which differs from that in FIG. 22 in the shape of the rectifying fluid 65. In the case shown in FIG. 23(a), the flow regulator 65 is curved in an arc toward the outside of the room. In the case shown in FIG. 23(b), the flow regulator 65 is bent from the middle portion toward the outside of the room. Even when the flow regulator 65 has such a shape, the flow of air can be made to follow the inner surface of the outer glass 1 similarly to the flow regulator 65 shown in FIG.

図24は、本発明の建具(単体サッシ)の第14実施形態を示している。フレームの構造、空気の流れる経路は、第13実施形態と同様である。本実施形態は、中間層10に整流体としてブラインド100が取付けてある。
ブラインド100は、上枠4の室外側の中空部25と室内側の中空部26の間の熱伝導遮断位置(断熱ブリッジ24)に取付けてある。ブラインド100の下端と下枠5の内周側面との間には、隙間101が設けてある。
FIG. 24 shows a fourteenth embodiment of the fitting (single sash) of the present invention. The structure of the frame and the path through which air flows are the same as in the thirteenth embodiment. In this embodiment, a blind 100 is attached to the intermediate layer 10 as a flow regulator.
The blind 100 is attached to a heat conduction blocking position (insulation bridge 24) between the hollow part 25 on the outdoor side of the upper frame 4 and the hollow part 26 on the indoor side. A gap 101 is provided between the lower end of the blind 100 and the inner peripheral side surface of the lower frame 5.

このように、中間層10に整流体としてブラインド100を設置した場合も、板状の整流体65を設置した場合と同様に、中間層10内の空気の流れを外側ガラス1の内側面と内側ガラス2の外側面に沿うように迂回させることができる上、中間層10を室内外に仕切って外側ガラス1の内側面に沿う空気の流れと内側ガラス2の外側面に沿う空気の流れとが混ざらないようにすることができる。
ブラインド100は、上枠4の熱伝導遮断位置(断熱ブリッジ24)の内周側に設けてあることで、ブラインド上部の結露が抑えられる。
In this way, even when the blind 100 is installed as a flow regulator in the intermediate layer 10, the flow of air in the intermediate layer 10 is directed between the inner surface of the outer glass 1 and the inner side, similar to the case where the plate-shaped flow regulator 65 is installed. In addition to being able to detour along the outer surface of the glass 2, the intermediate layer 10 is partitioned into indoor and outdoor areas to separate the air flow along the inner surface of the outer glass 1 and the air flow along the outer surface of the inner glass 2. You can prevent them from mixing.
Since the blind 100 is provided on the inner circumferential side of the heat conduction cutoff position (insulation bridge 24) of the upper frame 4, dew condensation on the upper part of the blind can be suppressed.

整流体65は、内外ガラス1,2間で下降する空気と上昇する空気とがぶつかり合って空気の流れが阻害されるのを防ぐもの、フレーム内に空気を通すためにフレームに設けた通気孔に確実に空気を導くものであればよく、板状のものやブラインドの他、ロールスクリーン等のスクリーンであってもよい(他の実施形態についても同様)。 The flow regulator 65 is a device that prevents the air flowing down and the air rising between the inner and outer glasses 1 and 2 from colliding with each other and obstructing the air flow, and is a vent hole provided in the frame to allow air to pass through the frame. It may be any material as long as it reliably guides air, and may be a screen such as a plate, a blind, or a roll screen (the same applies to other embodiments).

図25,26は、本発明の建具(単体サッシ)の第15実施形態を示している。本建具(単体サッシ)は、ビル用の引違いサッシに適用したものであり、躯体(図示省略)の開口部に取付けられる枠3と、枠3内に引違い状に開閉自在に納めた外障子13aと内障子13bとを備える。 25 and 26 show a fifteenth embodiment of the fitting (single sash) of the present invention.

The outer shoji 13a and the inner shoji 13b are constructed by assembling an upper stile 7, a lower stile 8, a door edge stile 115, and a closing stile 116 made of aluminum shapes into a four-circumference stile, and a panel unit 106 is installed inside the frame instead of double-glazed glass. It has been incorporated. The expected dimensions of the panel unit 106 are larger than the frames 7, 8, 115, and 116 of the shoji 13a and 13b, and the panel unit 106 of the outer shoji 13a protrudes to the outside of the room more than the frames 7, 8, 115, and 116. In the inner shoji 13b, the panel unit 106 protrudes further into the room than the frames 7, 8, 115, and 116.

パネルユニット106は、アルミ形材よりなる上フレーム103と下フレーム104と左右の縦フレーム105,105とを四周枠組みし、その枠内に外側ガラス1と内側ガラス2を嵌め込んで構成してある。

It is inserted through.

次に、障子13a,13bの組立て方を説明する。上フレーム103と下フレーム104と左右の縦フレーム105,105を、各フレームの内周側端部に形成した外側・内側ガラス保持部126,132に外側・内側ガラス1,2をそれぞれ嵌め込みながら枠組みし、パネルユニット106を組み立てる。その後、パネルユニット106外周の係止片119a,119bをガラス間口120に嵌め込みつつ、上框7と下框8と戸先框115と召合せ框116を框組みして障子13a,13bを組み立てる。組立てた障子13a,13bは、通常の障子と同じように、上枠4・下枠5間に室内側からけんどんで建て込む。 Next, how to assemble the shoji 13a, 13b will be explained. The upper frame 103, the lower frame 104, and the left and right vertical frames 105, 105 are assembled into frames by fitting the outer and inner glasses 1 and 2 into the outer and inner glass holding parts 126 and 132 formed at the inner circumferential ends of each frame, respectively. Then, the panel unit 106 is assembled. Thereafter, while fitting the locking pieces 119a and 119b on the outer periphery of the panel unit 106 into the glass opening 120, the upper stile 7, the lower stile 8, the door edge stile 115, and the matching stile 116 are assembled to assemble the shoji 13a and 13b. The assembled shoji 13a and 13b are installed between the upper frame 4 and the lower frame 5 from the indoor side in the same way as ordinary shoji.

本建具(単体サッシ)は、各障子13a,13bに取付けたパネルユニット106の室外側の通気部122と中間層10と室内側の通気部129を通じて室内外に空気が流れ、その際に中間層10を空気が外側パネル1と内側パネル2に沿うように迂回して流れることで、室内から室外に逃げる熱を回収するか、室外から室内に入ってくる熱を室外に捨て、これにより空気の流入する方向とは逆方向の熱移動が妨げられ、非常に優れた断熱効果を発揮する。
冬期の場合について説明すると、換気扇等により室内を負圧に調整し、図25に示すように、パネルユニット106を空気が室外から室内に向けて流れるようにする(図中の矢印は、空気の流れを示す)。室外側の通気口121から流入した冷たい空気(外気)は、弁体124に当たることで、外側ガラス1の室内側面に沿うように下向きに流出する。その後、冷たい空気はコールドドラフトにより中間層10の下まで流れてから折り返し、内側ガラス2から室内の熱が伝わることで暖められ、内側ガラス2の室外側面に沿って上昇し、この間に内側ガラス2から室外に逃げる熱を空気の流れによって回収する。その後、暖められた空気は弁体130にガイドされて室内側の通気口128から室内に流れる。空気が通気口128等からなる通気部129を通過する際にも、上フレーム103を伝って室内から室外に逃げる熱を空気の流れによって回収する。そうして暖められた空気を室内に取り入れることで、回収した熱を室内に戻すことができる。上フレーム103に整流板133を備えることで、内側ガラス2の室外側面に沿って上昇した空気が室外側に逆流し、室外側の通気部122からの冷たい空気の流れとぶつかるのを防ぎ、室内側の通気部129へと確実に導くことができる。
このように、中間層10内を外側ガラス1と内側ガラス2に沿うように迂回して空気が流れることで、室内から室外に伝わる熱を空気の流れによって回収し、室内に戻すことで、室内から室外への熱の損失がほとんどなくなるので、非常に高い断熱性が得られる。また、外気を暖めて室内に採り込めるので、室内に居る人が冷たい風を感じることがなく、暖房効率も良い。
In this fitting (single sash), air flows indoors and outdoors through the ventilation section 122 on the outdoor side of the panel unit 106 attached to each shoji 13a, 13b, the intermediate layer 10, and the ventilation section 129 on the indoor side. 10, the air detours along the outer panel 1 and the inner panel 2, and either recovers the heat escaping from the indoors to the outdoors, or discards the heat entering the indoors from the outdoors to the outdoors. Heat transfer in the opposite direction to the inflow direction is prevented, providing an excellent heat insulating effect.
In winter, the indoor pressure is adjusted to negative pressure using a ventilation fan, etc., and air flows through the panel unit 106 from outside to inside, as shown in Figure 25. flow). Cold air (outside air) flowing in from the vent 121 on the outside side hits the valve body 124 and flows out downward along the indoor side surface of the outside glass 1. After that, the cold air flows to the bottom of the intermediate layer 10 by a cold draft, turns around, is warmed by the indoor heat transmitted from the inner glass 2, and rises along the outdoor side of the inner glass 2, and during this time, the inner glass 2 The heat that escapes from the room to the outside is recovered by air flow. Thereafter, the warmed air is guided by the valve body 130 and flows into the room from the vent 128 on the indoor side. Even when air passes through a ventilation section 129 consisting of a ventilation port 128 and the like, the heat escaping from the room to the outside through the upper frame 103 is recovered by the air flow. By bringing the warmed air into the room, the recovered heat can be returned to the room. By providing the rectifying plate 133 on the upper frame 103, the air rising along the outdoor side of the inner glass 2 is prevented from flowing back to the outdoor side and colliding with the flow of cold air from the ventilation section 122 on the outdoor side. It can be reliably guided to the inner ventilation section 129.
In this way, the air flows through the middle layer 10 in a detour along the outer glass 1 and the inner glass 2, and the heat transmitted from the indoor to the outdoor is recovered by the air flow and returned to the indoor. Since there is almost no loss of heat from the inside to the outside, extremely high insulation properties can be obtained. In addition, since outside air can be warmed and brought into the room, people staying indoors do not feel cold wind, and the heating efficiency is good.

夏期には、換気扇等により室内を正圧に調整し、冬期とは逆に室内から室外に空気が流れるようにする。室内の空気の温度は室外よりも低いので、室内側の通気部129から中間層10に入った空気は内側ガラス2の室外側面に沿って下向きに流れ、その後、中間層10の下部で折り返し、外側ガラス1等の熱が伝わることで外側ガラス1の室内側面に沿って上昇し、この間に外側ガラス1を通じて室外から室内に入ってくる熱を空気の流れによって回収する。その後、室外側の通気部122を通って空気が室外に放出される。空気が通気部122を通過する際、上フレーム103を伝って室内に入ってくる熱を空気の流れによって回収する。そして、空気が室外に放出されることで、外側ガラス1や上フレーム103から回収した熱を室外に捨てる。このように室外から室内に伝わる熱を空気の流れによって回収し、室外に捨てることで、空気が流出する方向とは逆方向である室外側から室内側への熱輸送が妨げられ、優れた断熱効果を発揮して、室内が涼しく保たれる。 In the summer, use a ventilation fan to maintain positive pressure in the room so that air flows from the room to the outside, contrary to the situation in the winter. Since the temperature of the indoor air is lower than the outdoor air, the air that enters the intermediate layer 10 from the ventilation section 129 on the indoor side flows downward along the outdoor side of the inner glass 2, and then turns back at the lower part of the intermediate layer 10. The heat of the outer glass 1 and the like is transferred and rises along the indoor side surface of the outer glass 1, and during this time, the heat that enters the room from the outdoors through the outer glass 1 is recovered by the air flow. Thereafter, air is released outdoors through the ventilation section 122 on the outdoor side. When air passes through the ventilation section 122, the heat that passes through the upper frame 103 and enters the room is recovered by the air flow. Then, by releasing the air outdoors, the heat recovered from the outer glass 1 and the upper frame 103 is discarded outdoors. In this way, the heat transferred from the outdoors to the indoors is recovered by the air flow and discarded outdoors, which prevents heat transport from the outdoor side to the indoor side, which is the opposite direction to the direction in which the air flows out, resulting in excellent insulation. It works effectively and keeps the room cool.

本建具(単体サッシ)は、障子13a,13bの框7,8,115,116のガラス間口120に保持されるパネルユニット106に空気の流路を構成したことで、框7,8,115,116や枠3に特別な細工が不要なため、通常のサッシの障子のガラス間口120に本パネルユニット106を組み込むことにより、低コストで容易に実施することができる。既存の障子に後からパネルユニット106を組み込むことも可能である。 This fitting (single sash) has an air flow path configured in the panel unit 106 held in the glass frontage 120 of the frames 7, 8, 115, 116 of the shoji 13a, 13b. 116 and the frame 3, the present panel unit 106 can be easily implemented at low cost by incorporating it into the glass frontage 120 of a normal sash shoji. It is also possible to incorporate the panel unit 106 into an existing shoji screen later.

パネルユニット106は、フレーム103,104,105の内側ガラス2を保持する部分を別体で形成し、内側ガラス2が開閉又は着脱自在とすることができる。内側ガラス2を開閉又は着脱することで、空気が流れる内側ガラス2の外側面や外側ガラス1の内側面を掃除することができ、メンテナンス性が向上する。 In the panel unit 106, the portions of the frames 103, 104, and 105 that hold the inner glass 2 are formed separately, and the inner glass 2 can be opened and closed or detached. By opening/closing or attaching/detaching the inner glass 2, the outer surface of the inner glass 2 through which air flows and the inner surface of the outer glass 1 can be cleaned, improving maintainability.

パネルユニット106は、フレーム103,104,105の外側ガラス1を保持する部分と内側ガラス2を保持する部分とを熱的に分離してあってもよい。具体的には、外側ガラス1を保持する部分と内側ガラス2を保持する部分とを樹脂製のブリッジ材で連結したり、外側ガラス1を保持する部分をアルミで、内側ガラス2を保持する部分を樹脂で形成したりすることができる。また、フレーム全体を樹脂で形成することもできる。
そのように、フレーム103,104,105の外側ガラス1を保持する部分と内側ガラス2を保持する部分とを熱的に分離してあると、フレーム103,104,105を伝っての熱の出入りを防げることに加え、内側ガラス2を保持する部分に室外の冷気が伝わらないため(冬期の場合)、内側ガラス2に沿って上昇した空気がフレームに当たって冷やされるのを防げるので、断熱性能がより一層向上する。
In the panel unit 106, a portion of the frames 103, 104, 105 that holds the outer glass 1 and a portion that holds the inner glass 2 may be thermally separated. Specifically, the part that holds the outer glass 1 and the part that holds the inner glass 2 are connected using a resin bridge material, or the part that holds the outer glass 1 is made of aluminum and the part that holds the inner glass 2 is made of aluminum. can be made of resin. Alternatively, the entire frame can be made of resin.
If the parts of the frames 103, 104, 105 that hold the outer glass 1 and the parts that hold the inner glass 2 are thermally separated, heat can flow in and out through the frames 103, 104, 105. In addition, since the cold air from outside is not transmitted to the part that holds the inner glass 2 (in the winter), the air that rises along the inner glass 2 is prevented from hitting the frame and being cooled, which improves the insulation performance. Improve further.

フレーム(103,104,105)は、室外側と室内側で熱的に分離されていなくても、冬期は熱回収した空気をフレームを介さずに断熱パイプを通じて室内に取り込み、夏期は室内の空気をフレームを介さずに断熱パイプを用いて内外ガラス間の中間層10に直接送るようにしてもよい。 Even if the frames (103, 104, 105) are not thermally separated between the outdoor and indoor sides, in the winter, the heat-recovered air is taken into the room through the insulated pipes without going through the frame, and in the summer, the indoor air is It is also possible to send the liquid directly to the intermediate layer 10 between the inner and outer glass using a heat insulating pipe without passing through the frame.

第15実施形態の建具(単体サッシ)は、引違いサッシに限らず、枠3に一つの障子を開閉自在に支持したもの(例えば、たてすべり出し窓)に適用することもできる。この場合、当該障子の框のガラス間口120に外側ガラス1と内側ガラス2を有するパネルユニット106を支持したものでもよいし、框に外側ガラス1と内側ガラス2を直接支持したものでもよい。また、枠3にパネルユニット106を組み込んで嵌め殺し窓とすることもできる。 The fitting (single sash) of the fifteenth embodiment is not limited to a sliding sash, but can also be applied to a frame 3 that supports one shoji in a manner that it can be opened and closed (for example, a vertical sliding window). In this case, the panel unit 106 having the outer glass 1 and the inner glass 2 may be supported in the glass frontage 120 of the stile of the shoji, or the outer glass 1 and the inner glass 2 may be directly supported on the stile. Furthermore, the panel unit 106 can be assembled into the frame 3 to form a window that is fitted in the frame 3.

以上に述べたように第15実施形態の建具(単体サッシ)は、フレーム(上框7,下框8,戸先框115,召合せ框116)と、フレーム7,8,115,116のガラス間口120に保持したパネルユニット106を備え、パネルユニット106は、外側ガラス1と内側ガラス2を有し、室外と連通して外側ガラス1の内側面に沿って一方向に空気が流れ、ガラス1,2の端部付近で折り返し、室内と連通して内側ガラス2の外側面に沿って他方向に空気が流れることで、室内から室外に逃げる熱を回収するか、室外から室内に入ってくる熱を室外に捨てることで、窓からの熱の出入りを減らし、冷暖房効率を高めることができる。フレーム7,8,115,116のガラス間口120にパネルユニット106を組み込むだけでよいため、実施が容易である。 As described above, the fittings (single sash) of the fifteenth embodiment include the frame (upper stile 7, lower stile 8, door edge stile 115, and matching stile 116) and the glass of frames 7, 8, 115, and 116. The panel unit 106 includes a panel unit 106 held in a frontage 120, and the panel unit 106 has an outer glass 1 and an inner glass 2, and communicates with the outdoors so that air flows in one direction along the inner surface of the outer glass 1. , 2 is folded back near the end of the glass 2 and communicates with the interior of the room, allowing air to flow in the other direction along the outer surface of the inner glass 2 to recover the heat that escapes from the interior to the exterior, or that heat that enters the interior from the exterior. By discharging heat outside, you can reduce the amount of heat entering and exiting through windows and increase heating and cooling efficiency. Implementation is easy because it is only necessary to incorporate the panel unit 106 into the glass frontage 120 of the frames 7, 8, 115, 116.

第15実施形態の建具においても、第1実施形態のところで述べたように、夏期に空気を室外から室内に流すこともできる。この場合には、外側ガラス1側で貫流熱が減り、内側ガラス2側で冷熱を回収するので、非常に高い断熱性能が得られ、冷房負荷を抑えることができる。また、冬期に空気を室内から室外に流すこともできる。この場合には、外側ガラス1側で貫流冷熱を回収して室外に排出し、内側ガラス2側で貫流熱が減るため、非常に高い断熱性能が得られ、暖房負荷を抑えることができる。 Also in the fittings of the fifteenth embodiment, as described in the first embodiment, air can also be allowed to flow from the outdoors into the room during the summer. In this case, the flow-through heat is reduced on the outer glass 1 side and the cold heat is recovered on the inner glass 2 side, so that very high heat insulation performance can be obtained and the cooling load can be suppressed. It also allows air to flow from indoors to outdoors during the winter. In this case, the cold heat flowing through is recovered on the outer glass 1 side and discharged outdoors, and the heat flowing through is reduced on the inner glass 2 side, so that very high heat insulation performance can be obtained and the heating load can be suppressed.

本発明の建具は、一つのフレームに外側ガラス1と内側ガラス2を支持した単体サッシに限らず、外窓と内窓を備える二重窓であってもよい。 The fitting of the present invention is not limited to a single sash in which an outer glass 1 and an inner glass 2 are supported on one frame, but may also be a double-glazed window having an outer window and an inner window.

室外側通気部11と室内側通気部12はどこに設けてあってもよく、例えば外壁から中間層10にわたって室外側通気部11を設けたり、内壁から中間層10にわたって室内側通気部12を設けることもできる。 The outdoor ventilation section 11 and the indoor ventilation section 12 may be provided anywhere; for example, the outdoor ventilation section 11 may be provided from the outer wall to the intermediate layer 10, or the indoor ventilation section 12 may be provided from the inner wall to the intermediate layer 10. You can also do it.

図30は、本発明の建具の第16実施形態を示している。本実施形態の建具は、外側ガラス1の室内側に内側仕切体としてカーテン100を設けている。カーテン100の上方には、外側ガラス1とカーテン100との間の中間層10から室内空間に連通する室内側通気部12が設けてある。カーテン100の左右の縁部と下縁部は、マグネット101等で窓枠に固定して気密化してある。 FIG. 30 shows a sixteenth embodiment of the fitting of the present invention. In the fittings of this embodiment, a curtain 100 is provided as an inner partition on the indoor side of the outer glass 1. Above the curtain 100, an indoor ventilation section 12 is provided which communicates with the indoor space from the intermediate layer 10 between the outer glass 1 and the curtain 100. The left and right edges and the lower edge of the curtain 100 are fixed to the window frame with magnets 101 or the like to make them airtight.

本実施形態の建具は、第1実施形態等と同様に、外側ガラス1の内側面とカーテン100の外側面に沿うように空気を室外から室内、又は室内から室外に流すことで、高い断熱性能が得られ、冷暖房負荷を抑える効果がある。内側仕切体をカーテン100としたことで、外側ガラス1と内側ガラス2とでガラスを二重に設ける場合と比べて、コストを削減できる。カーテン100の上方に室内側通気部12を設けたので、中間層10に外側ガラス1の内側面とカーテン100の外側面に沿うように迂回する空気の流れを形成するのが容易である。カーテンレールとカーテン100との間の隙間を室内側通気部12として利用できる。 Similar to the first embodiment, the fittings of this embodiment have high heat insulation performance by allowing air to flow from the outdoors to the room or from the room to the outdoors along the inner surface of the outer glass 1 and the outer surface of the curtain 100. This has the effect of reducing heating and cooling loads. By using the curtain 100 as the inner partition, the cost can be reduced compared to the case where the outer glass 1 and the inner glass 2 are provided twice. Since the indoor ventilation section 12 is provided above the curtain 100, it is easy to form a detouring air flow in the intermediate layer 10 along the inner surface of the outer glass 1 and the outer surface of the curtain 100. The gap between the curtain rail and the curtain 100 can be used as the indoor ventilation section 12.

図31は、本発明の建具の第17実施形態を示している。本実施形態の建具は、外側ガラス1の室内側に内側仕切体としてロールスクリーン102を設けている。ロールスクリーン102の上部には、外側ガラス1とロールスクリーン102との間の中間層10から室内空間に連通する室内側通気部12が設けてある。ロールスクリーン102の左右の縁部と下縁部は、窓枠に取付けたガイドレール110に挿入して気密化してある。 FIG. 31 shows a seventeenth embodiment of the fitting of the present invention. In the fittings of this embodiment, a roll screen 102 is provided as an inner partition on the indoor side of the outer glass 1.

The heat exchanger 140 discharges the heat flowing through the room and the solar heat, and reduces the amount of cold heat flowing from the indoor side to the outside on the inside glass 2 side. By exchanging heat and recovering the cold energy from inside air, it is possible to supplement the function of the fittings and further reduce the cooling load.

図40は、本発明の換気システムの第4実施形態を示している。本換気システムは、内気を、建具に先に通してから熱交換器140に通した後に室外に排出するようにしている。それ以外は、第3実施形態と同様である。 Figure 40 shows a fourth embodiment of the ventilation system of the invention.

This ventilation system is configured by combining the fittings described above (see FIG. 29(b)) and a heat exchanger 140 installed in the ceiling. In this embodiment, the paths through which outside air and inside air flow are the same as in the third embodiment shown in FIG. 39.

熱交換器140は、給排気口144より導入した外気と空気取入口143より導入した内気とを熱交換する。内気の熱を回収することで温度が上がった外気は、空気吹出口142より室内に流入する。一方、内気と熱交換することで温度が下がった内気は、建具へと送られる。 The heat exchanger 140 exchanges heat between the outside air introduced through the air supply/exhaust port 144 and the inside air introduced through the air intake port 143. The outside air whose temperature has increased by recovering the heat of the inside air flows into the room through the air outlet 142. On the other hand, the inside air, whose temperature has decreased by exchanging heat with the inside air, is sent to the fittings.

その後、内気は、内側ガラス2の外側面に沿って下向きに流れ、中間層10の下端部で折り返し、外側ガラス1の外側面に沿って上向きに流れてから、室外に流出する。これにより本建具は、外側ガラス1側で室外側から室内側への貫流冷熱を回収して室外に排出し、内側ガラス2側で室内側から室外側への貫流熱が減るため、非常に高い断熱性能が得られ、暖房負荷を抑えることができる。 Thereafter, the inside air flows downward along the outer surface of the inner glass 2, turns back at the lower end of the intermediate layer 10, flows upward along the outer surface of the outer glass 1, and then flows out to the outside. As a result, this fixture collects the cold heat flowing from the outdoor side to the indoor side on the outside glass 1 side and discharges it to the outside, and reduces the heat flowing from the indoor side to the outdoor side on the inside glass 2 side, resulting in a very high Provides insulation performance and reduces heating load.

以上に述べたように第7実施形態の換気システムは、建具と熱交換機140を備え、内気を、熱交換器140に通してから建具に通した後に室外に排出し、外気を、熱交換器140に通してから室内に導入するものであり、建具の中間層10を内気が内側ガラス2の外側面と外側ガラス1の内側面に沿うように流れることで、外側ガラス1側で室外側から室内側への貫流冷熱を回収して室外に排出し、内側ガラス2側で室内側から室外側への貫流熱が減るため、非常に高い断熱性能が得られる上、熱交換器140で外気と内気を熱交換して内気の熱を回収することで、建具の働きを補完して暖房負荷をより一層削減することができる。 As described above, the ventilation system of the seventh embodiment includes the fittings and the heat exchanger 140, and the inside air is passed through the heat exchanger 140 and then through the fittings and then discharged outdoors, and the outside air is The inside air flows through the intermediate layer 10 of the fittings along the outer surface of the inner glass 2 and the inner surface of the outer glass 1, so that the outside glass 1 side is brought into the room. The heat exchanger 140 recovers the cold heat that flows from the indoor side to the outside and discharges it to the outside, and the heat that flows through from the indoor side to the outdoor side is reduced on the inner glass 2 side. By exchanging heat with the inside air and recovering the heat from the inside air, it is possible to supplement the function of the fittings and further reduce the heating load.

図44は、本発明の換気システムの第8実施形態を示している。本換気システムは、内気を、建具に先に通してから熱交換器140に通した後に室外に排出するようにしている。それ以外は、第7実施形態と同様である。 FIG. 44 shows an eighth embodiment of the ventilation system of the present invention. In this ventilation system, the inside air is first passed through the fittings and then through the heat exchanger 140 before being discharged to the outside. The rest is the same as the seventh embodiment.

第8実施形態の換気システムは、建具と熱交換機140を備え、内気を、建具に通してから熱交換器140に通した後に室外に排出し、外気を、熱交換器140に通してから室内に導入するものであり、建具の中間層10を内気が内側ガラス2の外側面と外側ガラス1の内側面に沿うように流れることで、外側ガラス1側で室外側から室内側への貫流冷熱を回収して室外に排出し、内側ガラス2側で室内側から室外側への貫流熱が減るため、非常に高い断熱性能が得られる上、熱交換器140で外気と内気を熱交換して内気の熱を回収することで、建具の働きを補完して暖房負荷をより一層削減することができる。 The ventilation system of the eighth embodiment includes fittings and a heat exchanger 140, inside air is passed through the fittings and then through the heat exchanger 140 before being discharged outdoors, and outside air is passed through the heat exchanger 140 and then exhausted. This is introduced indoors, and by flowing the inside air through the middle layer 10 of the fittings along the outer surface of the inner glass 2 and the inner surface of the outer glass 1, the flow can flow from the outdoor side to the indoor side on the outer glass 1 side. Cold heat is recovered and discharged outdoors, and the amount of heat passing through from the indoor side to the outdoor side is reduced on the inside glass 2 side, so very high insulation performance is obtained, and the heat exchanger 140 exchanges heat between outside air and inside air. By recovering the heat from the inside air, it is possible to supplement the function of the fittings and further reduce the heating load.

Figure 48 shows the proportion of the heating and cooling load in the example, based on the values of the heating and cooling load calculated for the example and the comparative example, and assuming that the heating and cooling load in the case of simply installing double-glazed windows (comparative example 1) is 100%. This is a graph. FIG. 49 is a graph showing the reduction rate of the heating/cooling load in each example compared to the case where a simple double-glazed window is installed (Comparative Example 1).
As is clear from FIGS. 48 and 49, it can be seen that in Examples 1 to 6, the cooling load can be suppressed in all cases compared to the case where a simple double-glazed window is installed (Comparative Example 1). In comparing Examples 1 and 2, which were constructed only with fittings, and Examples 3 to 6, which combined fittings and heat exchangers, Examples 3 to 6, which combined fittings and heat exchangers, had a lower cooling load. Highly effective in suppressing When comparing Example 3 in which outside air is passed through the fittings and then passed through the heat exchanger, and Example 4 in which the outside air is passed through the heat exchanger and then passed through the fittings, the cooling load is lower in Example 3 in which the outside air is passed through the fittings first. It is highly effective in suppressing In addition, in comparison with Example 5, in which the inside air is passed through the heat exchanger and then through the fittings, and Example 6, in which the inside air is passed through the fittings and then the heat exchanger, it is found that in Example 5, in which the inside air is passed through the heat exchanger first. This is more effective in reducing the cooling load.
Furthermore, as is clear from FIGS. 48 and 49, it can be seen that in Examples 7 to 12, the heating load can be suppressed in all cases compared to the case where a simple double-glazed window is installed (Comparative Example 1). Comparing Examples 7 and 8, which were constructed only with fittings, and Examples 9 to 12, which combined fittings and heat exchangers, Examples 9 to 12, which combined fittings and heat exchangers, had a lower heating load. Highly effective in suppressing In comparing Example 9 in which outside air is passed through the fittings and then passed through the heat exchanger, and Example 10 in which the outside air is passed through the heat exchanger and then passed through the fittings, Example 9 in which the outside air is passed through the fittings first has a lower heating load. It is highly effective in suppressing In addition, in comparison with Example 11, in which the inside air is passed through the heat exchanger and then through the fittings, and Example 12, in which the inside air is passed through the fittings and then the heat exchanger, in Example 11, in which the inside air is passed through the heat exchanger first. This is more effective in reducing the heating load.

以上に述べたように本換気システムは、建具の中間層10を外側ガラス1の内側面と内側ガラス2の外側面に沿うように外気又は内気が流れることで、建具単体でも冷暖房負荷を抑える効果がある上、建具と熱交換器140を組み合わせることで、熱交換器140が内気の冷熱又は熱を回収して建具の働きを補完するので、冷暖房負荷をより一層抑えることができる。 As described above, this ventilation system has the effect of reducing the heating and cooling load even for the fitting alone by allowing outside air or inside air to flow through the middle layer 10 of the fittings along the inner surface of the outer glass 1 and the outer surface of the inner glass 2. Moreover, by combining the fittings and the heat exchanger 140, the heat exchanger 140 recovers the cold or heat of the inside air to supplement the function of the fittings, so that the heating and cooling load can be further suppressed.
