まず、図８に示すように、貯湯タンク４０の上部に断熱カバー１０を配置し、矢印（１）で示すように、貯湯タンク４０の上部に断熱カバー１０を嵌め込んで、図９に示すような状態にする。 First, as shown in FIG. 8, the heat insulating cover 10 is arranged on the upper part of the hot water storage tank 40, and as shown by the arrow (1), the heat insulating cover 10 is fitted on the upper part of the hot water storage tank 40, as shown in FIG. Make it in a good state.

次いで、図９に示すように、各配管を、それぞれに対応する配管支持部の上部又は近傍に配置する。そして、矢印（２）で示すように、各配管を各配管支持部に当接させて支持させる。実際には、各配管を一本ずつ断熱カバー１０の配管支持部に載せる。その際、配管支持部に載せた配管の下端を貯湯タンク４０等に接続する。 Then, as shown in FIG. 9, each pipe is arranged in the upper part or the vicinity of the corresponding pipe support portion. Then, as shown by the arrow (2), each pipe is brought into contact with each pipe support portion to be supported. Actually, each pipe is placed on the pipe support portion of the heat insulating cover 10 one by one. At that time, the lower end of the pipe placed on the pipe support portion is connected to the hot water storage tank 40 or the like.

すなわち、配管１ａは、配管支持部３１に支持された後、下端が蒸発器７４に連結され、上端が地中熱交換器に連結される。配管１ｂは、配管支持部３２に支持された後、下端がポンプ８１に連結され、上端が地中熱交換器に連結される。配管２ａは、配管支持部３３に支持された後、下端のうちの一方が接続部２ｘにおいて貯湯タンク４０の側面に接続され、下端のうちの他方が凝縮器７２に連結される。また、配管２ａは、主管２ｍの上端が負荷装置に連結される。 That is, after the pipe 1a is supported by the pipe support portion 31, the lower end is connected to the evaporator 74 and the upper end is connected to the geothermal heat exchanger. After the pipe 1b is supported by the pipe support portion 32, the lower end is connected to the pump 81 and the upper end is connected to the geothermal heat exchanger. After the pipe 2a is supported by the pipe support portion 33, one of the lower ends is connected to the side surface of the hot water storage tank 40 at the connection portion 2x, and the other of the lower ends is connected to the condenser 72. Further, in the pipe 2a, the upper end of the main pipe 2m is connected to the load device.

配管２ｂは、配管支持部３４に支持された後、下端のうちの一方が接続部２ｙにおいて貯湯タンク４０の側面に接続され、下端のうちの他方がポンプ９１に連結される。また、配管２ｂは、上端が負荷装置に連結される。配管３ａは、配管支持部３５に支持された後、下端が接続部３ｘにおいて貯湯タンク４０の側面に接続され、上端が供給先に連結される。配管３ｂは、配管支持部３６に支持された後、下端が接続部３ｙにおいて貯湯タンク４０の側面に接続され、上端が供給元に連結される。 After the pipe 2b is supported by the pipe support portion 34, one of the lower ends is connected to the side surface of the hot water storage tank 40 at the connection portion 2y, and the other of the lower ends is connected to the pump 91. Further, the upper end of the pipe 2b is connected to the load device. After the pipe 3a is supported by the pipe support portion 35, the lower end is connected to the side surface of the hot water storage tank 40 at the connection portion 3x, and the upper end is connected to the supply destination. After the pipe 3b is supported by the pipe support portion 36, the lower end is connected to the side surface of the hot water storage tank 40 at the connection portion 3y, and the upper end is connected to the supply source.

以上のように、本実施の形態の断熱カバー１０は、複数の配管をそれぞれ個別に支持する複数の配管支持部３１～３６が側面部３０に形成されている。そして、複数の配管支持部３１～３６は、それぞれ、載置部と側面支持部とを有することから、貯湯タンク４０の周囲に配置される各配管を安定的に支持することができる。よって、貯湯タンク４０の周囲に配置される配管の連結作業を容易にし、作業効率の向上を図ることができる。すなわち、従来は、結束バンドなどの結束部材を用いて配管を断熱カバーの周囲に固定して連結作業を行っていたが、本実施の形態の断熱カバー１０は、複数の配管支持部を有するため、結束部材を用いることなく、各配管を安定的に支持することができる。そして、断熱カバー１０は、載置部３１ａ～３６ａに載せられた各配管の重さにより、上方向に外れにくくなる。 As described above, in the heat insulating cover 10 of the present embodiment, a plurality of pipe support portions 31 to 36 that individually support the plurality of pipes are formed on the side surface portions 30. Since each of the plurality of pipe support portions 31 to 36 has a mounting portion and a side surface support portion, each pipe arranged around the hot water storage tank 40 can be stably supported. Therefore, it is possible to facilitate the connection work of the pipes arranged around the hot water storage tank 40 and improve the work efficiency. That is, conventionally, the pipe is fixed around the heat insulating cover by using a binding member such as a binding band to perform the connecting work, but the heat insulating cover 10 of the present embodiment has a plurality of pipe support portions. , Each pipe can be stably supported without using a binding member. The heat insulating cover 10 is less likely to come off in the upward direction due to the weight of the pipes mounted on the mounting portions 31a to 36a.

また、複数の配管支持部３１～３６の載置部は、それぞれ、上面部２０と連続的に形成され、各配管の背面が接触する背面支持部と、各配管が載せられる支持側係合部と、を有している。よって、各配管の背面を２方向から支えることができるため、支持側係合部の作用と相まって、各配管をより安定的に支持することができる。 Further, the mounting portions of the plurality of pipe support portions 31 to 36 are formed continuously with the upper surface portion 20, respectively, and the back support portion with which the back surface of each pipe contacts and the support side engaging portion on which each pipe is mounted. And have. Therefore, since the back surface of each pipe can be supported from two directions, each pipe can be supported more stably in combination with the action of the support side engaging portion.

加えて、複数の配管支持部３１～３６の載置部は、支持側係合部の下端と連続的に形成され、各配管の背面を支持する下方支持部を有している。よって、各配管の背面を３箇所で支えることにより、各配管をさらに安定的に支持することができる。もっとも、複数の配管支持部３１～３６には、載置部が下方支持部を有しないものがあってもよく、複数の配管支持部３１～３６の全ての載置部が下方支持部を有しなくてもよい。 In addition, the mounting portions of the plurality of pipe support portions 31 to 36 are continuously formed with the lower ends of the support side engaging portions, and have a lower support portion that supports the back surface of each pipe. Therefore, by supporting the back surface of each pipe at three points, each pipe can be supported more stably. However, some of the plurality of pipe support portions 31 to 36 may not have a lower support portion, and all the mounting portions of the plurality of pipe support portions 31 to 36 have a lower support portion. You don't have to.

断熱カバー１０は、側面部３０の互いに対向する位置のそれぞれに、少なくとも１つの配管支持部が形成されている。本実施の形態における断熱カバー１０は、配管支持部３１及び３２と配管支持部３５及び３６とが対向するように配置されている。また、配管支持部３３は、配管支持部３５及び３６と対向するように配置されている。このようにすれば、配管によって断熱カバー１０を挟み込むことができるため、断熱カバー１０を安定的に支持することができる。 The heat insulating cover 10 is formed with at least one pipe support portion at each of the side surface portions 30 facing each other. The heat insulating cover 10 in the present embodiment is arranged so that the pipe support portions 31 and 32 and the pipe support portions 35 and 36 face each other. Further, the pipe support portion 33 is arranged so as to face the pipe support portions 35 and 36. By doing so, the heat insulating cover 10 can be sandwiched by the pipes, so that the heat insulating cover 10 can be stably supported.

断熱カバー１０は、配管支持部に対し配管の全体的な荷重がかかる方向を支持方向としたとき、少なくとも１つの配管支持部の支持方向と、他の少なくとも１つの配管支持部の支持方向とが、互いに交差するように構成されている。本実施の形態における断熱カバー１０は、例えば、配管支持部３１及び３２における支持方向と、配管支持部３５及び３６における支持方向とが交差している。また、配管支持部３３における支持方向は、配管支持部３１及び３２における支持方向と交差すると共に、配管支持部３５及び３６における支持方向とも交差している。加えて、配管支持部３４における支持方向は、配管支持部３１及び３２における支持方向と交差すると共に、配管支持部３５及び３６における支持方向と交差している。 The heat insulating cover 10 has a support direction of at least one pipe support portion and a support direction of the other at least one pipe support portion when the direction in which the entire pipe load is applied to the pipe support portion is defined as the support direction. , Are configured to intersect each other. In the heat insulating cover 10 of the present embodiment, for example, the support directions of the pipe support portions 31 and 32 and the support directions of the pipe support portions 35 and 36 intersect with each other. Further, the support direction in the pipe support portion 33 intersects with the support direction in the pipe support portions 31 and 32, and also intersects with the support direction in the pipe support portions 35 and 36. In addition, the support direction in the pipe support portion 34 intersects with the support direction in the pipe support portions 31 and 32, and also intersects with the support direction in the pipe support portions 35 and 36.

このように、多様な支持方向が組み合わさるように複数の配管支持部を形成し、複数の配管支持部をバランスよく配置することにより、断熱カバー１０の周方向の回転を抑制し、断熱カバー１０をより安定的に支持することができる。すなわち、ある配管支持部の支持方向と他の配管支持部の支持方向とが互いに交差するようにし、これらの配管支持部に配管を配置することにより、断熱カバー１０の固定強度を増加させることができる。なお、本実施の形態における断熱カバー１０は、各配管支持部における支持方向が、それぞれ、断熱カバー１０の中心部へ向かうように形成されている。 In this way, by forming a plurality of pipe support portions so that various support directions are combined and arranging the plurality of pipe support portions in a well-balanced manner, rotation of the heat insulating cover 10 in the circumferential direction is suppressed, and the heat insulating cover 10 is arranged. Can be supported more stably. That is, the fixing strength of the heat insulating cover 10 can be increased by arranging the pipes in the pipe support portions so that the support directions of one pipe support portion and the support directions of the other pipe support portions intersect each other. can. The heat insulating cover 10 in the present embodiment is formed so that the support direction in each pipe support portion is directed toward the central portion of the heat insulating cover 10.

断熱カバー１０は、複数の配管支持部３１～３６のうち、２以上の配管支持部が隣接して平行に形成されている。本実施の形態の断熱カバー１０は、配管支持部３１と配管支持部３２とが隣接して平行に形成され、配管支持部３５と配管支持部３６とが隣接して平行に形成されている。このようにすれば、多くの配管を貯湯タンク４０の周囲に安定的に配置することができる。もっとも、本実施の形態では、２つの配管支持部が隣接して平行に形成された例を図示したが、これに限らず、断熱カバー１０は、隣接して平行に形成された３つ以上の配管支持部を有していてもよい。 In the heat insulating cover 10, two or more pipe support portions of the plurality of pipe support portions 31 to 36 are adjacent to each other and are formed in parallel. In the heat insulating cover 10 of the present embodiment, the pipe support portion 31 and the pipe support portion 32 are formed adjacent to each other in parallel, and the pipe support portion 35 and the pipe support portion 36 are formed adjacent to each other in parallel. By doing so, many pipes can be stably arranged around the hot water storage tank 40. However, in the present embodiment, an example in which two pipe support portions are formed adjacent to each other in parallel is illustrated, but the present invention is not limited to this, and the heat insulating cover 10 is formed in parallel with three or more. It may have a pipe support portion.

タンクユニット５０の複数の配管は、それぞれ、側面が側面支持部に接触するように配置される上端部４ａと、上端部４ａの下端に接続され、載置部に接触するように配置される配管側係合部４ｂと、を有している。すなわち、タンクユニット５０の複数の配管は、それぞれ、上部が屈曲しており、その屈曲形状に合わせて各配管支持部が掘られている。したがって、各配管は各配管支持部によって安定的に支持される。 The plurality of pipes of the tank unit 50 are connected to the upper end portion 4a arranged so that the side surface is in contact with the side surface support portion and the lower end portion of the upper end portion 4a, respectively, and are arranged so as to be in contact with the mounting portion. It has a side engaging portion 4b and. That is, each of the plurality of pipes of the tank unit 50 has a bent upper portion, and each pipe support portion is dug according to the bent shape. Therefore, each pipe is stably supported by each pipe support portion.

また、断熱カバー１０の複数の配管支持部３１～３６は、それぞれ、各配管の上端部４ａと配管側係合部４ｂとによる屈曲形状に合わせた形状となっている。そして、貯湯タンク４０の周囲に配置される複数の配管の各々の屈曲形状は、互いに異なっている。したがって、各配管と各配管支持部との対応関係を一見して把握することができるため、どの配管をどの配管支持部に配置するかを容易に見分けることができる。すなわち、タンクユニット５０の組み立ての際、配管の上部と、断熱カバー１０に形成されている配管支持部の形状とを見比べることにより、各配管を簡単に正しい位置へ配置することができる。 Further, the plurality of pipe support portions 31 to 36 of the heat insulating cover 10 each have a shape that matches the bending shape of the upper end portion 4a and the pipe side engaging portion 4b of each pipe. The bent shapes of the plurality of pipes arranged around the hot water storage tank 40 are different from each other. Therefore, since the correspondence between each pipe and each pipe support portion can be grasped at a glance, it is possible to easily distinguish which pipe is arranged in which pipe support portion. That is, when assembling the tank unit 50, each pipe can be easily arranged at the correct position by comparing the upper part of the pipe with the shape of the pipe support portion formed on the heat insulating cover 10.

さらに、配管２ａは、２つの上端部４ａを有しており、これら２つの上端部４ａは、配管側係合部４ｂによって連結されている。したがって、配管２ａは、配管支持部３３に載せた状態において、主管２ｍの上端部４ａが、背面支持部３３ｈｙ、下方支持部３３ｎ、及び側面支持部３３ｂに支持され、分岐管２ｎの上端部４ａが、背面支持部３３ｈｘ及び側面支持部３３ｂに支持される。加えて、配管２ａは、配管側係合部４ｂが支持側係合部３３ｋに係合する。よって、配管２ａは、配管支持部３３によって安定的に支持することができる。なお、上記実施の形態では、２つの上端部４ａを有する配管として配管２ａのみを例示したが、これに限らず、タンクユニット５０は、２つの上端部４ａを有する複数の配管を有していてもよい。 Further, the pipe 2a has two upper end portions 4a, and these two upper end portions 4a are connected by a pipe side engaging portion 4b. Therefore, in the state where the pipe 2a is placed on the pipe support portion 33, the upper end portion 4a of the main pipe 2m is supported by the back support portion 33hy, the lower support portion 33n, and the side surface support portion 33b, and the upper end portion 4a of the branch pipe 2n is supported. Is supported by the back surface support portion 33hx and the side surface support portion 33b. In addition, in the pipe 2a, the pipe-side engaging portion 4b engages with the support-side engaging portion 33k. Therefore, the pipe 2a can be stably supported by the pipe support portion 33. In the above embodiment, only the pipe 2a is exemplified as the pipe having the two upper end portions 4a, but the tank unit 50 is not limited to this, and the tank unit 50 has a plurality of pipes having the two upper end portions 4a. May be good.

さらに、タンクユニット５０において、複数の配管のうちの少なくとも１つは、下端が貯湯タンク４０の側面に接続されている。本実施の形態では、配管２ａの下端のうちの一方と、配管２ｂの下端のうちの一方とが、貯湯タンク４０の側面に接続されている。そして、配管２ａ及び配管２ｂは、貯湯タンク４０の側面に沿って上方向に伸びており、上部が配管支持部によって支持されている。したがって、特許文献１の断熱カバーのように、複数の配管をまとめて通過させる大きな開口部を中央部に設ける必要がない。つまり、断熱カバーを発砲断熱材と蓋部材とに分けて作成する必要がないため、本実施の形態の構成を採れば、断熱カバーの形成が容易となる。 Further, in the tank unit 50, the lower end of at least one of the plurality of pipes is connected to the side surface of the hot water storage tank 40. In the present embodiment, one of the lower ends of the pipe 2a and one of the lower ends of the pipe 2b are connected to the side surface of the hot water storage tank 40. The pipe 2a and the pipe 2b extend upward along the side surface of the hot water storage tank 40, and the upper portion is supported by the pipe support portion. Therefore, unlike the heat insulating cover of Patent Document 1, it is not necessary to provide a large opening in the central portion through which a plurality of pipes can pass together. That is, since it is not necessary to separately create the heat insulating cover for the foamed heat insulating material and the lid member, the heat insulating cover can be easily formed by adopting the configuration of the present embodiment.

上記の実施の形態は、断熱カバー及びタンクユニットにおける好適な具体例であり、本発明の技術的範囲は、これらの態様に限定されるものではない。例えば、上記の実施の形態では、貯湯タンク４０の周囲に６本の配管が配置される例を示したが、これに限定されない。タンクユニット５０において、貯湯タンク４０の周囲に配置される配管は、２本以上５本以下であってもよく、７本以上であってもよい。加えて、配管支持部の形状は、各図に例示した形状に限らず、各配管の上部形状に合わせて適宜変更することができる。ただし、配管支持部は、載置部と側面支持部とを有するように構成する。 The above embodiments are suitable specific examples of the heat insulating cover and the tank unit, and the technical scope of the present invention is not limited to these embodiments. For example, in the above embodiment, an example in which six pipes are arranged around the hot water storage tank 40 is shown, but the present invention is not limited to this. In the tank unit 50, the number of pipes arranged around the hot water storage tank 40 may be 2 or more and 5 or less, or 7 or more. In addition, the shape of the pipe support portion is not limited to the shape illustrated in each figure, and can be appropriately changed according to the upper shape of each pipe. However, the pipe support portion is configured to have a mounting portion and a side surface support portion.

また、図１では、配管２ｂの下端のうちの一方が貯湯タンク４０の側面に直接的に接続された例を示したが、これに限らず、配管２ｂの下端のうちの一方は、別に設けられた冷媒回路等の熱交換器を介して貯湯タンク４０の側面に接続されてもよい。配管２ａの下端のうちの一方も同様、別に設けられた冷媒回路等の熱交換器を介して貯湯タンク４０の側面に接続されてもよい。なお、ブライン回路８０を循環させる熱媒体として、水などのブライン以外の熱媒体を採用してもよい。 Further, FIG. 1 shows an example in which one of the lower ends of the pipe 2b is directly connected to the side surface of the hot water storage tank 40, but the present invention is not limited to this, and one of the lower ends of the pipe 2b is provided separately. It may be connected to the side surface of the hot water storage tank 40 via a heat exchanger such as a refrigerant circuit. Similarly, one of the lower ends of the pipe 2a may be connected to the side surface of the hot water storage tank 40 via a heat exchanger such as a separately provided refrigerant circuit. As the heat medium for circulating the brine circuit 80, a heat medium other than brine such as water may be adopted.
