Abstract

PROBLEM TO BE SOLVED: To provide a branch chamber having less variation in an air blowing volume and capable of increasing the whole of the air blowing volume.SOLUTION: A branch chamber includes a main duct connection part in a front face, a plurality of outlets in a side face of the front face, a branch plate inside, and a laminar flow part having a certain length from the main duct connection part in an opposite face direction. The branch plate has a width spreading radially from a center axis of the branch chamber and is constituted by a plate extending from the front face in the opposite face direction.

Description

本発明は、空気調和された空気を、空調装置と必要とする複数の部屋とをダクトを通して連通接続するための分岐チャンバに関するものである。   The present invention relates to a branch chamber for connecting air-conditioned air to an air conditioner and a plurality of required rooms through a duct.

従来の分岐チャンバは、主ダクト接続口から流入した空気が各吹出し口に分配される際に、対面に配置された吹出し口の風量が側面に配置された吹出し口よりも多くなるなど、各吹出し口の風量が均一にならなかった。   In the conventional branch chamber, when the air flowing in from the main duct connection port is distributed to each outlet, the air volume of the outlet arranged on the opposite side becomes larger than the outlet arranged on the side, etc. Mouth air volume was not uniform.

特許文献1で示される発明では、平面状底面中央部に主ダクト接続口を設けて、複数の吹出し口を上部の球面状側面に設けることで改善を図っている。ただ、球面状の側面から全周に吹出し口があるため、壁際などに設置しにくい等の施工上の問題があった。 In the invention shown in Patent Document 1, improvement is achieved by providing a main duct connection port at the center of the flat bottom surface and providing a plurality of outlets on the upper spherical side surface. However, since there are outlets from the spherical side to the entire circumference, there were problems in construction such as being difficult to install on the wall.

特許文献２で示される発明では、施工が容易な構造であり、空調機の小型化および空調エネルギの削減を図ることができるとある。本発明の課題と共通する風量のバラツキについては、誘引ガイドと分岐チャンバ部との間の空調ダクト内にガイドベーンを設置することで解決を図っている。   The invention disclosed in Patent Document 2 has a structure that is easy to construct, and can reduce the size of the air conditioner and reduce the energy of air conditioning. The air flow variation common to the problem of the present invention is solved by installing guide vanes in the air conditioning duct between the attraction guide and the branch chamber section.

ただし、この特許文献２の発明では、確かに分岐チャンバ部に送り込まれる空気の均質化は図ることはできるが、主ダクト接続部以降の部分で見れば、分岐チャンバ内に流入した空気は分岐チャンバ本体内で渦を発生させるなどの乱流を生ずることがあるので、分岐チャンバ本体内の均質性の問題は依然として残る。   However, in the invention of Patent Document 2, it is possible to homogenize the air sent to the branch chamber part, but if viewed in the part after the main duct connection part, the air flowing into the branch chamber is The problem of homogeneity within the branch chamber body still remains because turbulence, such as generating vortices in the body, can occur.

本発明はこのような状況に鑑み、分岐チャンバ内部にて吹出し風量のバラツキを抑えて、吹出し口からの各空気風量の不均一化の問題を解決する。   In view of such a situation, the present invention solves the problem of non-uniformity of the air flow rates from the air outlets by suppressing the variation in the air flow rates inside the branch chamber.

特に、特許文献１の発明では、主ダクト接続部からの空気が分岐チャンバに流入する際に曲がりがあるので、流入する空気が偏る。そのため、流れが乱れることで全体風量が減少する問題があるので、これを解決する。   In particular, in the invention of Patent Document 1, since the air from the main duct connection portion is bent when flowing into the branch chamber, the flowing air is biased. Therefore, there is a problem that the total air volume decreases due to the disturbance of the flow, and this is solved.

さらに、製造、施工上の理由で、設置場所に制約がないように、平面構造をなす分岐チャンバを提供する。 Furthermore, a branch chamber having a planar structure is provided so that the installation location is not restricted for manufacturing and construction reasons.

本発明は、正面に主ダクト接続部と、その側面に複数の吹出し口と、内部に分流板と、主ダクト接続部から対面方向に一定の長さを有する層流部とを備える分岐チャンバであって、前記分流板は分岐チャンバの中心軸から放射状に広がった幅を持ち、正面から対面方向に延伸する板で構成されていることを特徴とする分岐チャンバの発明である。   The present invention is a branch chamber comprising a main duct connecting portion on the front surface, a plurality of outlets on the side surface, a flow dividing plate inside, and a laminar flow portion having a certain length in the facing direction from the main duct connecting portion. The diverter plate is an invention of the branch chamber characterized in that it has a width that spreads radially from the central axis of the branch chamber and is formed of a plate that extends in the facing direction from the front.

また、本発明は、前記層流部は主ダクト接続部の口径よりも大きな長さを持つことを特徴とし、また、前記分流板は、主ダクト接続部から、その口径Ｌ以上の長さを有し、水平および垂 直の二枚以上の交差平板であることを特徴とし、さらに、
前記吹出し口は、上下二段以上の構成であることを特徴とする分岐チャンバにかかる発明である。 Further, the present invention is characterized in that the laminar flow portion has a length larger than the diameter of the main duct connection portion, and the flow dividing plate has a length equal to or larger than the diameter L from the main duct connection portion. It has two or more intersecting flat plates, horizontal and vertical, and
The outlet is an invention according to a branch chamber characterized by having a configuration of two or more upper and lower stages.

このように、本発明によれば、分岐チャンバにおける吹出し風量のバラツキを抑えて、全体風量の向上を実現する。また設置場所に制約がなく、床面、天井、或いは壁面に容易に設置できるという効果がある。 As described above, according to the present invention, the variation in the blown air volume in the branch chamber is suppressed, and the overall air volume is improved. Further, there is no restriction on the installation location, and there is an effect that it can be easily installed on the floor, ceiling or wall.

以下、本発明の実施形態にかかる分岐チャンバについて図面に基づいて説明する。まず、図１
に示すように空調設備システムは、空調機(図外)で形成された調和空気を送給するための空調ダクト１１と、主ダクト接続部１０から送り込まれる主調和空気１２を複数方向に分岐して送り出すための分岐チャンバ１と、を備えている。分岐チャンバ１から吹出し口２０から複数方向に分岐して送り出された分岐調和空気２２はそれぞれ分岐ダクト２１を経由して各部屋の給気口３０から室内へ送り込まれる。分岐とは複数に吹出されて送り出されるものであり、この平面図では、吹出し口２０、分岐ダクト２１および分岐調和空気２２並びに給気口３０には、例として４系等でａ，ｂ，ｃ，ｄと符合添え字している。なお、本平面図では見えていないが、各吹出し口は上下複数段に配置可能とする。 Hereinafter, a branch chamber according to an embodiment of the present invention will be described with reference to the drawings. First, FIG.
As shown in FIG. 1, the air conditioning equipment system branches an air conditioning duct 11 for supplying conditioned air formed by an air conditioner (not shown) and a main conditioned air 12 fed from the main duct connecting portion 10 in a plurality of directions. And a branch chamber 1 for feeding out. Branched conditioned air 22 branched and sent out from the branch chamber 1 in a plurality of directions from the outlet 20 is sent into the room through the branch duct 21 from the air inlet 30 of each room. The branch is blown out and sent out in a plurality. In this plan view, the outlet 20, the branch duct 21, the branch conditioned air 22, and the air supply port 30 are a, b, c, for example, as a 4 system. , D. Although not shown in the plan view, each outlet can be arranged in a plurality of stages.

さて、分岐チャンバ１の構成について、図２で示す。図２Ａは分岐チャンバを上方から見た平面図である。図２Ｂは、主ダクト接続部にかかる正面図である。なお、図２Ａの平面図では分岐チャンバ１に内蔵される分岐板５，６を示すために内部を透過的に図示している。 Now, the configuration of the branch chamber 1 is shown in FIG. FIG. 2A is a plan view of the branch chamber as viewed from above. FIG. 2B is a front view of the main duct connecting portion. In the plan view of FIG. 2A, the inside is shown transparently to show the branch plates 5 and 6 built in the branch chamber 1.

分岐チャンバ１は立方体状の筐体をなす。主ダクト接続部１０を正面として捉えると、側面に吹出し口２０がある。吹出し口２０は２段構成である。ここで、分岐チャンバ１の主ダクト接続部１０から所定の区間は吹出し口２０を側部に設けないものであり、層流部２と呼ぶ。   The branch chamber 1 forms a cubic housing. If the main duct connection part 10 is caught as a front surface, the outlet 20 is provided on the side surface. The outlet 20 has a two-stage configuration. Here, a predetermined section from the main duct connecting portion 10 of the branch chamber 1 is one in which the outlet 20 is not provided in the side portion and is referred to as a laminar flow portion 2.

層流部２は主ダクト接続部１０から所定の長さはＸである。主ダクト接続部１０の開口部の径をＬとすると、次の関係式（１）を満足することが望ましい。
Ｘ ＞＝ Ｌ ・・・・（１）
分岐チャンバに流入直後の主調和空気１２を安定化するバッファの役目である。 The laminar flow part 2 has a predetermined length X from the main duct connection part 10. When the diameter of the opening of the main duct connecting portion 10 is L, it is desirable to satisfy the following relational expression (1).
X> = L (1)
This is a role of a buffer for stabilizing the main conditioned air 12 immediately after flowing into the branch chamber.

次に、分岐板５ないし６について述べる。分岐板は分岐チャンバ１の正面から分岐チャンバ１の長手方向に延伸して置かれるものである。その中心はチャンバの中心軸４（図中一点鎖線で示す）に置かれる。このように、分流板５，６はチャンバの中心から放射状に広がって流路に沿って延伸する板で構成される。こうすることで、分岐チャンバ内の調和空気に整流の効果を奏する。 Next, the branch plates 5 to 6 will be described. The branch plate is placed extending from the front of the branch chamber 1 in the longitudinal direction of the branch chamber 1. Its center is placed on the central axis 4 of the chamber (indicated by a dashed line in the figure). As described above, the flow dividing plates 5 and 6 are configured by plates extending radially from the center of the chamber and extending along the flow path. By doing so, a rectifying effect is exerted on the conditioned air in the branch chamber.

分流板を５，６のように２枚(上下左右４方向)で構成した場合には、吹出し口２０は上下二段構成することが望ましい。整流された空気をそのまま各吹出し口に導くためである。   When the flow dividing plate is composed of two sheets (5 directions, up and down, left and right), it is desirable that the outlet 20 has two upper and lower stages. This is because the rectified air is directly led to each outlet.

さて、分流板は必ずしも図２Ｂのように、水平および垂直の２枚で構成される場合ばかりではない。さらに図２Ｃのとおり、２枚の分流板７，８を正面から見て４５度回転させた位置に設けることもよい。更なる分岐の効果を図るためである。この場合は、吹出し口２０は縦に四段に構成することが可能になる。このようにして吹出し口２０を多段に構成して分岐調和空気２２の分配数を増やすことができる。 Now, as shown in FIG. 2B, the flow dividing plate is not necessarily limited to the case where the flow dividing plate is composed of two horizontal and vertical plates. Furthermore, as shown in FIG. 2C, the two flow dividing plates 7 and 8 may be provided at a position rotated by 45 degrees when viewed from the front. This is for the purpose of further branching effects. In this case, the outlet 20 can be configured vertically in four stages. Thus, the number of distribution of the branch conditioned air 22 can be increased by configuring the outlets 20 in multiple stages.

（その他の実施例）
さらに、図３に示したように、室内機(図外)に直接組み付けるサプライチャンバ方式においても同様に吹出し口からの風量を均一にできる。ここでは、図３Ａの平面図にあるように、分岐チャンバ１は、所定の層流部２とテーパー状の分岐端部３から構成される。
図３Ｂに示す主ダクト接続部１０からの正面図で見るように、分岐板はここでは唯一垂直方向しかない。端部のテーパー形状のため一枚の分岐板としているが、これでチャンバ内の風量のバラツキを低減できる。 (Other examples)
Further, as shown in FIG. 3, even in the supply chamber system that is directly assembled to the indoor unit (not shown), the air volume from the outlet can be made uniform. Here, as shown in the plan view of FIG. 3A, the branch chamber 1 includes a predetermined laminar flow portion 2 and a tapered branch end portion 3.
As seen in the front view from the main duct connection 10 shown in FIG. 3B, the branch plate is here only in the vertical direction. Although one branch plate is formed because of the tapered shape at the end, it is possible to reduce variation in the air volume in the chamber.

以上のように、本発明の実施態様を説明したが、種種の設計変更等は任意であり、その様な設計にあっても、本発明の趣旨を逸脱しないかぎり、本発明の範囲に属するものと理解するべきである。例えば、分流板の水平・垂直の捉え方は、分岐チャンバ１を壁面に横付けしたような場合には逆に解釈する必要があるなど、注意が必要である。   As described above, the embodiments of the present invention have been described. However, various design changes and the like are arbitrary, and even such designs are within the scope of the present invention without departing from the spirit of the present invention. Should be understood. For example, it is necessary to pay attention to how the horizontal and vertical directions of the flow dividing plate are interpreted when the branch chamber 1 is placed on the wall.
