1 is an overall schematic diagram showing a refrigerant circuit branch unit of an air-conditioning apparatus according to Embodiment 1 of the present invention, FIG. 2 is a side view showing an installation state of the branch unit according to Embodiment 1 of the present invention, and FIG. side view of a refrigerant circuit branch unit of an air conditioner according to the first embodiment of the invention, FIG 4 is an exploded perspective view showing a refrigerant circuit branch unit of the air conditioner according to embodiment 1 of the present invention, Figure 5 is the It is a front exploded view which shows the refrigerant circuit branch unit of the air conditioning apparatus by Embodiment 1 of invention . In the figure, the air conditioner 1 includes one outdoor unit 2 and a plurality of indoor units 3. The outdoor unit 2 includes a part of a refrigerant circuit such as an outdoor heat exchanger, a compressor, and a four-way valve, a fan that allows air to flow to exchange heat with the outdoor heat exchanger, and a motor that drives the fan. A control circuit (none of which is shown) for controlling the device is incorporated. The indoor unit 3 includes a part of a refrigerant circuit such as an indoor heat exchanger, a fan that causes air to flow to exchange heat in the indoor heat exchanger, a motor that drives the fan, and control of the device. A control circuit (none of which is shown in the figure) is included. The refrigerant circuit in the outdoor unit 2 and the refrigerant circuit of the indoor unit 3 are connected via a refrigerant liquid pipe 5 and a refrigerant gas pipe 6, and the indoor unit 3 is connected to the refrigerant liquid pipe 5 on the outdoor unit 2 side. A branch unit 4 for branching to the refrigerant gas pipe 6 on the side is installed on the way.

前記分岐ユニット４の外郭は主に、上下方向に開放したケーシング７と、このケーシング７の上開口部に取り付けられる上蓋８、また、ケーシング７の下開口部に取り付けられる下蓋９で構成されている。前記ケーシング７の一方側面には室外機２側に接続される室外機２側配管取出口１１が設けられており、室外機側のガス管１２、液管１３を延出させ、このガス管１２、液管１３を押さえ込む押え部材１１ａを備えている。また、ケーシング７の他方側面には前記室内機３側に接続される配管を取り出す室内機３側配管取出口１４が設けられており、室内機側ガス管１５、液管１６を延出させ、このガス管１５、液管１６を押さえ込む第２の押え部材１４ａを備えている。さらに、前記ケーシング７内部の冷媒回路１０は、上下に２分割された前記室内機側ガス管１５、液管１６上側を密着状態で押さえる室内機側ガス管押え１７ａ、液管押え１７ｂ、室外機側ガス管押え１７ｃおよび液管押え１７ｄを備えた上断熱材１７と、同じく前記室外側ガス管１２、液管１３下側を密着状態で押える室内機側ガス管押え１８ａ、液管押え１８ｂ、室外機側ガス管押え１８ｃおよび液管押え１８ｄを備えた下断熱材１８によって気密状態に組立て密閉されると同時に保持される。そして、前記冷媒回路分岐ユニット４は、図２に示すように天井１９などに設けられた点検口２０から見える位置に天井梁２２に吊り具２１により据付けられている。 The outer shell of the branch unit 4 is mainly composed of a casing 7 opened in the vertical direction, an upper lid 8 attached to the upper opening of the casing 7, and a lower lid 9 attached to the lower opening of the casing 7. Yes. An outdoor unit 2 side pipe outlet 11 connected to the outdoor unit 2 side is provided on one side surface of the casing 7, and the gas pipe 12 and the liquid pipe 13 on the outdoor unit side are extended. The holding member 11a for pressing the liquid pipe 13 is provided. Further, the other side surface of the casing 7 is provided with an indoor unit 3 side pipe outlet 14 for taking out a pipe connected to the indoor unit 3 side, and extends the indoor unit side gas pipe 15 and the liquid pipe 16, A second presser member 14 a for pressing the gas pipe 15 and the liquid pipe 16 is provided. Further, the refrigerant circuit 10 inside the casing 7 includes an indoor unit side gas pipe presser 17a, a liquid pipe presser 17b, and an outdoor unit that press the upper side of the indoor unit side gas pipe 15 and the liquid pipe 16 that are divided into two vertically. The upper heat insulating material 17 provided with the side gas pipe presser 17c and the liquid pipe presser 17d, and the indoor unit side gas pipe presser 18a, the liquid pipe presser 18b, which press the lower side of the outdoor gas pipe 12 and the liquid pipe 13 in a close contact state. The outdoor unit side gas pipe presser 18c and the liquid pipe presser 18d are assembled and sealed in an airtight state by the lower heat insulating material 18 and are held at the same time. The refrigerant circuit branching unit 4 is installed on the ceiling beam 22 by a hanger 21 at a position that can be seen from an inspection port 20 provided on the ceiling 19 or the like as shown in FIG .

次に、冷媒回路分岐ユニット４をメンテナンスする場合は、最初に、ケーシング７の上蓋８もしくは下蓋９を取り外す。そして、上断熱材１７もしくは下断熱材１８が露出するので、これらのいずれかを取り外す。上断熱材１７もしくは下断熱材１８を取外した状態で冷媒回路１０が露出するため、メンテナンスすることが容易に可能となる。メンテナンスが終了した後は、前述と逆の順序で部品を装着すれば良い。   Next, when maintaining the refrigerant circuit branch unit 4, first, the upper lid 8 or the lower lid 9 of the casing 7 is removed. And since the upper heat insulating material 17 or the lower heat insulating material 18 is exposed, either of these is removed. Since the refrigerant circuit 10 is exposed with the upper heat insulating material 17 or the lower heat insulating material 18 removed, maintenance can be easily performed. After the maintenance is completed, the components may be mounted in the reverse order as described above.

分岐ユニット４は、通常、天井裏・床下・高所などに設置される事が多く、メンテナンス作業者は、点検口２０を通して分岐ユニット４の上方向もしくは下方向でメンテナンス作業する。よって、冷媒回路１０を上方向もしくは下方向から直接確認できるため、メンテナンス性が良い。 In many cases, the branch unit 4 is usually installed behind the ceiling, under the floor, or in a high place, and the maintenance worker performs maintenance work in the upward or downward direction of the branch unit 4 through the inspection port 20. Therefore, since the refrigerant circuit 10 can be directly confirmed from the upper direction or the lower direction, the maintainability is good.

以上の実施の形態１は、冷媒回路１０を、上下に２分割された上断熱材１７と下断熱材１８によって密閉したものである。これは、温度が低くなった冷媒回路１０への結露防止を目的とするが、部品の寸法精度が低いと上断熱材１７と下断熱材１８の接合面に隙間が生じ、気密性が保てず結露する可能性がある。これを回避するため、図７に示す様な鈎形状の上鈎接合面１７ｅと下鈎接合面１８ｅとすることにより、接合面部が増加すると同時に嵌合性が向上し、気密性が向上することが出来る。   In the first embodiment described above, the refrigerant circuit 10 is sealed by the upper heat insulating material 17 and the lower heat insulating material 18 which are divided into two vertically. This is intended to prevent dew condensation on the refrigerant circuit 10 at a low temperature. However, if the dimensional accuracy of the parts is low, a gap is generated at the joint surface between the upper heat insulating material 17 and the lower heat insulating material 18 to maintain airtightness. There is a possibility of condensation. In order to avoid this, by using the upper collar joint surface 17e and the lower collar joint surface 18e as shown in FIG. 7, the joint surface area increases, and at the same time, the fitting property is improved and the airtightness can be improved. .

また、前記上断熱材１７と下断熱材１８の接合面にシール材（図示されていない）を設けても同等の効果を得ることが出来る。   Further, even if a sealing material (not shown) is provided on the joint surface between the upper heat insulating material 17 and the lower heat insulating material 18, the same effect can be obtained.
