Abstract

<P>PROBLEM TO BE SOLVED: To provide a flow divider capable of making the state of gas-liquid separation of a fluid uniform. <P>SOLUTION: The flow divider 200 has an annular passage 50 between an entrance side pipe arrangement 1 and exit side pipe arrangements 11, 12, 13. This configuration causes the fluid that flows into the annular passage 50 from the entrance side pipe arrangement 1 to circulate within the annular passage 50. In this way, the state of gas-liquid separation of the fluid within the annular passage 50 is made uniform. As a result, the state of gas-liquid separation of the fluid flowing out of the annular passage 50 into the plurality of exit side pipe arrangements 11, 12, 13 becomes almost equal. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、入口側配管から複数の出口側配管へ流体を流す分流器に関するものである。   The present invention relates to a shunt for flowing a fluid from an inlet side pipe to a plurality of outlet side pipes.

従来から、入口側配管から流入した流体が複数の出口側配管から流出される分流器が用いられている。分流器は、たとえば、１つの室外熱交換器から流れ込む流体を複数の室内熱交換器に分配するマルチタイプエアコンにおいて用いられている。分流器においては、図１０に示すように、入口側配管１に接続された流体溜り部５００を経て仕切弁１１１、１１２、１１３のそれぞれを介して出口側配管１１、１２、１３に冷媒が流れ込んでいる。
実公昭５８−１０９４２号 実公昭５９−１８２７７号 実開昭６３−２２５６８号公報 2. Description of the Related Art Conventionally, a shunt has been used in which a fluid that flows in from an inlet side pipe flows out from a plurality of outlet side pipes. The shunt is used in, for example, a multi-type air conditioner that distributes a fluid flowing from one outdoor heat exchanger to a plurality of indoor heat exchangers. In the flow divider, as shown in FIG. 10, the refrigerant flows into the outlet side pipes 11, 12, and 13 through the gate valves 111, 112, and 113 through the fluid reservoir 500 connected to the inlet side pipe 1. It is out.
No. 58-10942 Actual Kosho 59-18277 Japanese Utility Model Publication No. 63-22568

上記従来の分流器においては、液溜り部５０は、入口側配管１よりは径が大きいが、入口側配管１に連続して接続された一直線状に延びる円筒状部である。したがって、液溜り部５０内において発生する偏流によって流体の気液分離状態に偏りが生じ、複数の出口側配管１１、１２、１３のいずれかへ流れ込む流体には、気体が多く混ざっているという不具合が生じる場合もある。   In the conventional shunt, the liquid reservoir 50 is a cylindrical portion extending in a straight line continuously connected to the inlet side pipe 1, although the diameter is larger than that of the inlet side pipe 1. Therefore, the gas-liquid separation state of the fluid is biased due to the drift generated in the liquid reservoir 50, and the fluid that flows into any of the plurality of outlet-side pipes 11, 12, 13 contains a large amount of gas. May occur.

本発明は、上述の問題に鑑みなされたものであり、その目的は、流体の気液分離状態の均一化が図られた分流器を提供することである。   The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a flow divider in which the gas-liquid separation state of the fluid is made uniform.

本発明の分流器は、入口側配管と、入口側配管に接続された環状路と、環状路に接続された複数の出口側配管とを備えている。これによれば、複数の出口側配管のそれぞれに流れ込む流体の気液分離状態を均一化させることができる。   The shunt of the present invention includes an inlet side pipe, an annular path connected to the inlet side pipe, and a plurality of outlet side pipes connected to the annular path. According to this, the gas-liquid separation state of the fluid flowing into each of the plurality of outlet side pipes can be made uniform.

また、環状路に逆止弁が設けられていれば、環状路内での流体の流れが安定するため、複数の出口側配管のそれぞれに流れ込む流体の気液分離状態をより均一化させることができる。   In addition, if a check valve is provided in the annular passage, the flow of fluid in the annular passage is stabilized, so that the gas-liquid separation state of the fluid flowing into each of the plurality of outlet side pipes can be made more uniform. it can.

また、環状路がその一部に他の部分よりも流路断面が小さい部分を有すれば、その部分での流体の流速が大きくなるため、流体の均一化がより確実に図られる。   Further, if the annular path has a part having a smaller channel cross-section than the other part in the part, the flow velocity of the fluid in that part becomes larger, so that the fluid can be made more uniform.

また、環状路がほぼ円形であり、入口側配管と複数の出口側配管とが円周上に均等に配置されていてもよい。   Further, the annular path may be substantially circular, and the inlet side pipe and the plurality of outlet side pipes may be evenly arranged on the circumference.

また、入口側配管と環状路とは三方継手によって接続されていれば、環状路へ流れ込む流体の流れが一方向に固定され易いため、複数の出口側配管のそれぞれに流れ込む流体の気液分離状態をより均一化させることができる。また、入口側配管と環状路とは分岐継手によって接続されていてもよい。   In addition, if the inlet side pipe and the annular path are connected by a three-way joint, the flow of the fluid flowing into the annular path is easily fixed in one direction, so the gas-liquid separation state of the fluid flowing into each of the plurality of outlet side pipes Can be made more uniform. The inlet side pipe and the annular path may be connected by a branch joint.

以下、図を参照しながら、本発明の実施の形態の分流器を説明する。
実施の形態の分流器２００は、三方継手１０と、三方継手１０の３つの接続部のうちの一つに接続された入口側配管１と、両端が三方継手１０の他の２つの接続部に接続された環状路５０と、環状路５０に仕切弁１１１、１１２、１１３を介して接続された出口側配管１１、１２、１３とを備えている。 Hereinafter, a shunt according to an embodiment of the present invention will be described with reference to the drawings.
The shunt 200 according to the embodiment includes a three-way joint 10, an inlet-side pipe 1 connected to one of the three connections of the three-way joint 10, and both ends connected to the other two connections of the three-way joint 10. An annular passage 50 connected to the annular passage 50 and outlet pipes 11, 12, and 13 connected to the annular passage 50 via gate valves 111, 112, and 113 are provided.

上記の分流器２００には、入口側配管１内を流れている流体が流入する。環状路５０内では、流体が循環する。このとき、流体は攪拌されるため、たとえば、流体が空気調和機に使用されるフロンのような冷媒であれば、冷媒の気液分離状態が均一化される。したがって、出口側配管１１、１２、１３を流れる冷媒の気液分離状態がほぼ同一になる。その結果、前述の分流器２００が、複数の室内熱交換器と１つの室外熱交換器とが分流器を介して接続されているような、いわゆるマルチタイプエアコンに用いられる場合には、複数の室内熱交換器を流れる冷媒の気液分離状態がほぼ同一になる。また、通常のセパレートタイプエアコンにおいて、室内機（室内熱交換器を含む）内で冷媒を複数のパスに分流させる場合に前述の分流器を用いても、同様に、複数のパスにおける冷媒の気液分離状態をほぼ同一にすることができる。したがって、複数の室内熱交換器の冷房能力をほぼ同一にすることができる。また、入口側配管１から環状路５０内へ大きな流速で流体が流れ込んでも、環状路５０から出口側配管１１、１２、１３へ流れ出す流体の速度はそれほど大きくない。つまり、流体速度が環状路５０内で低減される。流体速度が分流器の分配性能へ与える悪影響を低減することが可能になる。   The fluid flowing in the inlet side pipe 1 flows into the flow divider 200. A fluid circulates in the annular path 50. At this time, since the fluid is agitated, for example, if the fluid is a refrigerant such as Freon used in an air conditioner, the gas-liquid separation state of the refrigerant is made uniform. Therefore, the gas-liquid separation state of the refrigerant flowing through the outlet side pipes 11, 12, and 13 is substantially the same. As a result, when the aforementioned flow divider 200 is used in a so-called multi-type air conditioner in which a plurality of indoor heat exchangers and one outdoor heat exchanger are connected via a flow divider, The gas-liquid separation state of the refrigerant flowing through the indoor heat exchanger becomes almost the same. Further, in a normal separate type air conditioner, when the refrigerant is divided into a plurality of paths in an indoor unit (including an indoor heat exchanger), the refrigerant gas in the plurality of paths is similarly used. The liquid separation state can be made substantially the same. Therefore, the cooling capacity of the plurality of indoor heat exchangers can be made substantially the same. Further, even if a fluid flows from the inlet side pipe 1 into the annular path 50 at a high flow rate, the speed of the fluid flowing out from the annular path 50 to the outlet side pipes 11, 12, 13 is not so high. That is, the fluid velocity is reduced in the annular path 50. It is possible to reduce the adverse effect of the fluid velocity on the distribution performance of the flow divider.

また、図１に示すように、環状路５０には、逆止弁６０が設けられている。そのため、環状路５０内の流体は常に一方向において循環する。したがって、環状路５０内での流体の逆流に起因する淀み部の発生がないため、流体の気液分離状態の均一性がより向上する。但し、図２に示す環状路５０に逆止弁が設けられていない分流器２００であっても、入口側配管１から環状路５０に流れ込む流体の経路が一直線状でれば、環状路５０内を流体がスムーズに循環し易いため、図１に示す分流器２００と同様の効果を得ることが可能となる。したがって、環状路５０と入口側配管１との接続には、図１に示すようなＴ型の三方継手（いわゆるチーズ）１０が用いられることが望ましい。   As shown in FIG. 1, a check valve 60 is provided in the annular path 50. Therefore, the fluid in the annular passage 50 always circulates in one direction. Therefore, since the stagnation part resulting from the backflow of the fluid in the annular path 50 does not occur, the uniformity of the fluid-gas separation state is further improved. However, even in the flow divider 200 in which the check valve is not provided in the annular path 50 shown in FIG. 2, if the path of the fluid flowing into the annular path 50 from the inlet side pipe 1 is straight, Therefore, it is possible to obtain the same effect as that of the flow divider 200 shown in FIG. Therefore, it is desirable to use a T-shaped three-way joint (so-called cheese) 10 as shown in FIG. 1 for the connection between the annular path 50 and the inlet side pipe 1.

また、図３に示すように、分流器２００は、その一部に他の部分より管径が小さな部分を含んでいてもよい。たとえば、管径が相対的に大きな部分５０ａと管径が相対的に小さな部分５０ｃとを備えていてもよい。管径が大きな部分５０ａと管径が小さな部分５０ｃとは、円錐状の接続部５０ｂおよび５０ｄによって接続されている。このように、環状路１０において管径が相対的に小さな部分があれば、管径が小さな部分において流体の速度が大きくなるため、循環路５０内での流体の循環がより一層スムーズに行なわれる。その結果、流体の気液分離特性がより一層向上する。   Moreover, as shown in FIG. 3, the flow divider 200 may include a part having a smaller pipe diameter than the other part. For example, a portion 50a having a relatively large tube diameter and a portion 50c having a relatively small tube diameter may be provided. The portion 50a having a large tube diameter and the portion 50c having a small tube diameter are connected by conical connection portions 50b and 50d. In this way, if there is a portion having a relatively small tube diameter in the annular passage 10, the fluid speed increases in the portion having a small tube diameter, so that the fluid is circulated more smoothly in the circulation passage 50. . As a result, the gas-liquid separation characteristics of the fluid are further improved.

また、図４に示すように、環状路５０は、平面的に見てほぼ円形をしており、その円形の環状路５０に、入口側配管１、出口側配管１１、１２、１３が互いに均等な間隔を隔てて配置されていてもよい。また、図５に示すように、入口側配管１と環状路５０とが分岐継手（Ｙ型継手）２０によって接続されていてもよい。   Further, as shown in FIG. 4, the annular path 50 has a substantially circular shape when seen in a plan view, and the inlet side pipe 1 and the outlet side pipes 11, 12, 13 are equal to each other in the circular annular path 50. You may arrange | position with a sufficient space | interval. As shown in FIG. 5, the inlet side pipe 1 and the annular path 50 may be connected by a branch joint (Y-type joint) 20.

さらに、図６および図７に示すように、入口側配管１と出口側配管１１、１２、１３とが互いに垂直な方向に延びる分流器において、環状路５０が用いられても、前述の効果と同様の効果得ることができる。また、図８および図９に示すように、入口側配管１と出口側配管１１、１２、１３とが互いに平行に延びるような分流器において、環状路５０が用いられても、前述の効果と同様の効果得ることができる。   Further, as shown in FIGS. 6 and 7, even if the annular passage 50 is used in the flow divider in which the inlet side pipe 1 and the outlet side pipes 11, 12, and 13 extend in a direction perpendicular to each other, the above-described effects are obtained. Similar effects can be obtained. Further, as shown in FIGS. 8 and 9, even if the annular passage 50 is used in the flow divider in which the inlet side pipe 1 and the outlet side pipes 11, 12, 13 extend in parallel with each other, the above-described effects are obtained. Similar effects can be obtained.
