Description

空気調和装置及び空気調和装置の製造方法Air conditioner and method of manufacturing air conditioner
　本発明は、側板が設けられた熱交換器を備える空気調和装置及びその空気調和装置の製造方法に関する。 The present invention relates to an air conditioner including a heat exchanger provided with a side plate and a method for manufacturing the air conditioner.
　空気調和装置に用いられる熱交換器は、例えば放熱フィンとチューブと側板とで構成されている。放熱フィン及びチューブは複数設けられており、複数のチューブが複数の放熱フィンに挿入されている。側板はチューブの端部に設けられており、側板には、複数のチューブが挿入される複数の穴が形成されている。熱交換器には、側板において、複数のチューブ同士を接続する接続部材が設けられている。この接続部材としては、例えばＵベンド管、三方ベンド管及びバルジ三方管等が挙げられる。また、チューブがヘアピン管である場合、チューブと接続部材とは一体的に形成される。 The heat exchanger used in the air conditioner is composed of, for example, heat radiation fins, tubes, and side plates. A plurality of radiation fins and tubes are provided, and a plurality of tubes are inserted into the plurality of radiation fins. The side plate is provided at the end of the tube, and the side plate is formed with a plurality of holes into which the plurality of tubes are inserted. The heat exchanger is provided with a connection member for connecting a plurality of tubes on the side plate. Examples of the connecting member include a U-bend pipe, a three-way bend pipe, and a bulge three-way pipe. When the tube is a hairpin tube, the tube and the connecting member are integrally formed.
　このような熱交換器に設けられる接続部材は、その接続パターン（パスパターン）が様々で且つ複雑である。このため、パスパターンが記載された図面が、別途用意される。そして、熱交換器を製造する作業者は、熱交換器とパスパターンが記載された図面とを交互に見比べつつ部品等を取り付けて組み立てている。パスパターンに関する部品は、多い場合、熱交換器１枚当たり１００個を超えることもある。また、その部品は、数種類に及ぶ場合もある。従って、作業時間が増加し、取り付け間違いによる仕損が発生する虞がある。 The connection member provided in such a heat exchanger has various and complicated connection patterns (path patterns). For this reason, a drawing in which a path pattern is described is prepared separately. And the operator who manufactures a heat exchanger attaches parts etc., and assembles, comparing the heat exchanger and the drawing in which the pass pattern was described alternately. In many cases, the number of parts related to the path pattern may exceed 100 per heat exchanger. In addition, there may be several types of parts. Therefore, the work time increases, and there is a possibility that a failure due to an attachment error occurs.
　また、パスパターンに関する部品は、前述の如く、主に、ヘアピン管、Ｕベンド管、三方ベンド管及びバルジ三方管の４種類である。これらの接続部材は、機能、外形、取り付け数及び場所等に制限がない。このため、取り付け場所の確認及び取り付ける接続部材自体の確認に起因する作業時間の増加、取り付け場所の確認及び取り付ける接続部材自体の確認に起因する取り付け間違いによる仕損が発生する虞がある。 Also, as described above, there are mainly four types of parts related to the pass pattern: hairpin tube, U-bend tube, three-way bend tube, and bulge three-way tube. These connecting members are not limited in function, external shape, number of attachments, location, and the like. For this reason, there is a possibility that an increase in work time due to the confirmation of the mounting location and the confirmation of the connecting member itself to be attached, and a failure due to an attachment error due to the confirmation of the mounting location and the confirmation of the connecting member itself to be attached may occur.
　なお、これらの接続部材がロウ付けによって取り付けられる場合、一旦取り付けられると、取り外しが困難である。このため、取り付け間違いが発生した場合、放熱フィン及び側板を含む熱交換器全体を廃棄しなければならない。 In addition, when these connecting members are attached by brazing, once attached, it is difficult to remove. For this reason, when an attachment mistake occurs, the entire heat exchanger including the radiation fins and the side plates must be discarded.

　図５は、本発明の実施の形態１に係る空気調和装置１の製造方法を示すフローチャートである。次に、空気調和装置１の製造方法について説明する。先ず、側板１３に、複数のチューブ１２が挿入される複数の穴１３ａが形成される。具体的には、第１の熱交換器４の側板１３となる平板状の金属板に、例えばバーリング処理によって複数の穴１３ａが形成される（ステップＳＴ１）。 FIG. 5 is a flowchart showing a method for manufacturing the air-conditioning apparatus 1 according to Embodiment 1 of the present invention. Next, the manufacturing method of the air conditioning apparatus 1 is demonstrated. First, a plurality of holes 13 a into which a plurality of tubes 12 are inserted are formed in the side plate 13. Specifically, a plurality of holes 13a are formed in the flat metal plate that becomes the side plate 13 of the first heat exchanger 4 by, for example, burring (step ST1).
　次に、側板１３において、接続対象となる複数のチューブ１２に対応する穴１３ａの間に、複数のチューブ１２を接続する接続部材１４の種類に対応したマーキング１５が施される。具体的には、複数の穴１３ａ同士の間に、刻印治具によってマーキング１５が打刻される（ステップＳＴ２）。そして、金属板の上端部及び下端部が９０°曲げられる。これにより、第１の熱交換器４の側板１３が製造される（ステップＳＴ３）。その後、この側板１３を用いて第１の熱交換器４が製造され、その第１の熱交換器４を用いて空気調和装置１が製造される。 Next, on the side plate 13, markings 15 corresponding to the types of connecting members 14 that connect the plurality of tubes 12 are provided between the holes 13a corresponding to the plurality of tubes 12 to be connected. Specifically, the marking 15 is stamped by a marking jig between the plurality of holes 13a (step ST2). And the upper end part and lower end part of a metal plate are bent 90 degrees. Thereby, the side plate 13 of the first heat exchanger 4 is manufactured (step ST3). Thereafter, the first heat exchanger 4 is manufactured using the side plate 13, and the air conditioner 1 is manufactured using the first heat exchanger 4.
　次に、本実施の形態１に係る空気調和装置１の運転状態について説明する。圧縮機３は、冷媒を吸入し、この冷媒を圧縮して高温高圧のガスの状態で吐出する。この吐出された冷媒は、第１の熱交換器４に流入し、第１の熱交換器４は、室外空気との熱交換により、冷媒を凝縮する。凝縮された冷媒は、膨張部５に流入し、膨張部５は、凝縮された冷媒を膨張及び減圧する。そして、減圧された冷媒は、第２の熱交換器６に流入し、第２の熱交換器６は、室内空気との熱交換により、冷媒を蒸発する。このとき、室内空気が冷却されて、室内が冷房される。そして、蒸発されて高温低圧のガスの状態となった冷媒は、圧縮機３に吸入される。 Next, the operating state of the air conditioner 1 according to Embodiment 1 will be described. The compressor 3 sucks the refrigerant, compresses the refrigerant, and discharges the refrigerant in a high-temperature and high-pressure gas state. The discharged refrigerant flows into the first heat exchanger 4, and the first heat exchanger 4 condenses the refrigerant by exchanging heat with outdoor air. The condensed refrigerant flows into the expansion unit 5, and the expansion unit 5 expands and depressurizes the condensed refrigerant. Then, the decompressed refrigerant flows into the second heat exchanger 6, and the second heat exchanger 6 evaporates the refrigerant by exchanging heat with room air. At this time, the room air is cooled and the room is cooled. Then, the refrigerant that has been evaporated to become a high-temperature and low-pressure gas state is sucked into the compressor 3.
　このように、本実施の形態１にかかる空気調和装置１は、冷房運転を行う際に用いられるものであるが、冷媒回路２に流路切替部を設けることによって、冷房運転だけでなく暖房運転も実施可能に構成されてもよい。 As described above, the air-conditioning apparatus 1 according to the first embodiment is used when the cooling operation is performed. By providing the flow path switching unit in the refrigerant circuit 2, not only the cooling operation but also the heating operation is performed. May also be configured to be feasible.
　図６は、本発明の実施の形態１における第１の熱交換器４の側板１３を示す正面図である。次に、本実施の形態１に係る空気調和装置１の作用について説明する。図６において、実線矢印は、第１の熱交換器４の一端部の側板１３に取り付けられる接続部材１４の取り付け位置と、冷媒の流通方向とを示すものである。また、図６において、破線は、第１の熱交換器４の他端部の側板１３に取り付けられる接続部材１４の取り付け位置を示すものである。このように、第１の熱交換器４においては、両端部の側板１３で取り付けられる接続部材１４が異なるため、両端部の側板１３には、夫々異なるマーキング１５が施されている。 FIG. 6 is a front view showing the side plate 13 of the first heat exchanger 4 according to Embodiment 1 of the present invention. Next, the effect | action of the air conditioning apparatus 1 which concerns on this Embodiment 1 is demonstrated. In FIG. 6, a solid line arrow indicates the attachment position of the connection member 14 attached to the side plate 13 at one end of the first heat exchanger 4 and the refrigerant flow direction. In FIG. 6, the broken line indicates the attachment position of the connection member 14 attached to the side plate 13 at the other end of the first heat exchanger 4. Thus, in the 1st heat exchanger 4, since the connection member 14 attached by the side plate 13 of both ends differs, the marking 15 which is different is given to the side plate 13 of both ends, respectively.
　図６に示すように、各接続部材１４は、マーキング１５の種類に応じて取り付けられる。例えば、２本の平行な直線のマーキング１５が施された部分には、Ｕベンド管１４Ａが取り付けられる。また、２本の直交する直線のマーキング１５が施された部分には、三方ベンド管１４ｂが取り付けられる。更に、破線においてはマーキング１５が図示されていないが、ヘアピン管（チューブ１２）が取り付けられる。そして、流入ヘッダ４ａから流入した冷媒は、ヘアピン管（チューブ１２）、Ｕベンド管１４Ａ、ヘアピン管（チューブ１２）、三方ベンド管１４ｂの順に流通する。 As shown in FIG. 6, each connecting member 14 is attached according to the type of marking 15. For example, a U-bend tube 14A is attached to a portion where two parallel straight markings 15 are provided. A three-way bend pipe 14b is attached to a portion where two orthogonal straight markings 15 are provided. Furthermore, although the marking 15 is not shown in the broken line, a hairpin tube (tube 12) is attached. And the refrigerant | coolant which flowed in from the inflow header 4a distribute | circulates in order of the hairpin pipe | tube (tube 12), U bend pipe | tube 14A, the hairpin pipe | tube (tube 12), and the three-way bend pipe | tube 14b.
　三方ベンド管１４ｂで分岐した冷媒の一方は、ヘアピン管（チューブ１２）、Ｕベンド管１４Ａ、ヘアピン管（チューブ１２）、Ｕベンド管１４Ａ、ヘアピン管（チューブ１２）の順に流通して第１の流出ヘッダ４ｂに流出する。また、三方ベンド管１４ｂで分岐した冷媒の他方は、ヘアピン管（チューブ１２）、Ｕベンド管１４Ａ、ヘアピン管（チューブ１２）、Ｕベンド管１４Ａ、ヘアピン管（チューブ１２）の順に流通して第１の流出ヘッダ４ｂに流出する。 One of the refrigerants branched by the three-way bend tube 14b flows in the order of the hairpin tube (tube 12), the U bend tube 14A, the hairpin tube (tube 12), the U bend tube 14A, and the hairpin tube (tube 12). It flows out to the outflow header 4b. Further, the other refrigerant branched by the three-way bend pipe 14b flows in the order of the hairpin pipe (tube 12), the U bend pipe 14A, the hairpin pipe (tube 12), the U bend pipe 14A, and the hairpin pipe (tube 12). 1 outflow header 4b.
　以上説明したように、側板１３には、接続対象となる複数のチューブ１２に対応する穴１３ａの間に、複数のチューブ１２を接続する接続部材１４の種類に対応したマーキング１５が施されている。このため、サポート材がなくとも、位置決めが容易である。従って、製造コストを削減することができる。また、マーキング１５は、接続部材１４の種類毎に異なるため、取り付ける接続部材１４を容易に認識することができる。このため、複数の接続部材１４が存在する場合においても取り付け作業性を向上させることができる。 As described above, the side plate 13 is provided with the markings 15 corresponding to the types of the connecting members 14 that connect the plurality of tubes 12 between the holes 13a corresponding to the plurality of tubes 12 to be connected. . For this reason, positioning is easy even without a support material. Therefore, the manufacturing cost can be reduced. Further, since the marking 15 is different for each type of the connecting member 14, the connecting member 14 to be attached can be easily recognized. For this reason, attachment workability | operativity can be improved even when the some connection member 14 exists.
　また、これにより、第１の熱交換器４に接続部材１４を取り付ける時間を短縮することができる。また、取り付け作業性が向上するため、第１の熱交換器４の品質を向上させることができる。更に、接続部材１４がロウ付けによって取り付けられても、取り付け間違いの発生を抑制することができるため、放熱フィン１１及び側板１３を含む第１の熱交換器４全体を廃却するリスクを軽減することができる。これにより、省エネルギーに資する。 This also shortens the time for attaching the connection member 14 to the first heat exchanger 4. Moreover, since attachment workability | operativity improves, the quality of the 1st heat exchanger 4 can be improved. Furthermore, even if the connection member 14 is attached by brazing, it is possible to suppress the occurrence of attachment mistakes, so that the risk of discarding the entire first heat exchanger 4 including the radiation fins 11 and the side plates 13 is reduced. be able to. This contributes to energy saving.

In this case, the refrigerant flowing in from the expansion part 5 flows through the hairpin tube, the U-bend tube 14A, the three-way bend tube 14b, etc., and flows out to the second outflow header 6b. Moreover, in Embodiment 1, the marking 15 is given to the side plate 13 of the first heat exchanger 4, but the marking 15 may be given to the side plate 13 of the second heat exchanger 6.
　また、チューブ１２はヘアピン管であり、チューブ１２と接続部材１４とは一体的に形成されている。これにより、ヘアピン管の取り付け作業性を向上させることができる。 Further, the tube 12 is a hairpin tube, and the tube 12 and the connecting member 14 are integrally formed. Thereby, the attachment workability | operativity of a hairpin pipe | tube can be improved.
