Abstract
Description
本発明は、貯湯槽から複数の住戸に給湯をおこなうための給湯システムに関するものである。 The present invention relates to a hot water supply system for supplying hot water from a hot water storage tank to a plurality of dwelling units.
集合住宅において、１箇所に設置された貯湯槽から各住戸に給湯をおこなうことで、設備コストやランニングコストを抑えることができる給湯システムが知られている（特許文献１−３参照）。 In a housing complex, a hot water supply system is known that can suppress equipment costs and running costs by supplying hot water from a hot water tank installed in one place to each dwelling unit (see Patent Documents 1-3).
この貯湯槽に貯める湯は、共用の電気及び水を使用して作られるので、特許文献１には、各住戸に分岐される給湯配管に湯量計を設けることで、各住戸の使用量を把握できるようにした構成が開示されている。 Since the hot water stored in this hot water tank is made using common electricity and water, in Patent Document 1, the amount of water used in each dwelling unit is grasped by installing a hot water meter in the hot water supply pipe branched into each dwelling unit. A configuration that can be made is disclosed.
また、特許文献２には、貯湯槽から各住戸を回って貯湯槽に戻る循環用配管を設けることで、各住戸において安定した温度の湯がすぐに使用できるようにした構成が開示されている。 Patent Document 2 discloses a configuration in which hot water having a stable temperature can be immediately used in each dwelling unit by providing a circulation pipe that goes around each dwelling unit from the hot water tank and returns to the hot water storage tank. .
さらに、特許文献３には、循環中に低下する湯の温度を効率的に上昇させるための保温機能を有する保温用循環ポンプを備えた給湯システムの構成が開示されている。 Furthermore, Patent Document 3 discloses a configuration of a hot water supply system including a heat-retaining circulation pump having a heat-retaining function for efficiently increasing the temperature of hot water that decreases during circulation.
しかしながら、特許文献１に開示された給湯システムは、湯を循環させる経路がないため、各住戸で給湯栓を開けてから一定の温度の湯が吐出されるまでに時間がかかる。 However, since the hot water supply system disclosed in Patent Document 1 does not have a route for circulating hot water, it takes time to open hot water at a certain temperature after the hot water tap is opened in each dwelling unit.
一方、特許文献２の給湯システムでは、各住戸の中まで循環用配管を引き込むため、配管コストが高くなるうえに、各住戸の配管の上流側と下流側に２つの湯量計又は湯量計と定流量弁を設けなければならず、コストが嵩む。また、特許文献３の給湯システムも各住戸にまで循環用配管を引き込むため、配管コストが高くなる。 On the other hand, in the hot water supply system of Patent Document 2, since the circulation pipe is drawn into each dwelling unit, the piping cost is increased, and two hot water meters or hot water meters are fixed on the upstream side and the downstream side of the piping of each dwelling unit. A flow valve must be provided, which increases costs. Moreover, since the hot water supply system of patent document 3 also draws in the piping for circulation to each dwelling unit, piping cost becomes high.
そこで、本発明は、給湯栓を開けた直後から安定した温度の湯が供給されるとともに、配管コストを抑えることが可能な給湯システムを提供することを目的としている。 SUMMARY OF THE INVENTION An object of the present invention is to provide a hot water supply system that can supply hot water at a stable temperature immediately after opening a hot water tap and that can suppress piping costs.
前記目的を達成するために、本発明の給湯システムは、貯湯槽から複数の住戸に給湯をおこなうための給湯システムであって、共用空間に設置される給湯用の加熱手段としてのヒートポンプ式加熱装置と、前記ヒートポンプ式加熱装置に接続されるとともに同じ前記共用空間に設置される貯湯槽と、前記貯湯槽から複数の住戸に向けて配管されるとともに供給されなかった湯を貯湯槽に戻すための循環経路と、前記循環経路から各住戸に引き込まれるとともに前記循環経路に戻る経路がない枝管とを備えたことを特徴とする。 In order to achieve the above object, a hot water supply system of the present invention is a hot water supply system for supplying hot water from a hot water storage tank to a plurality of dwelling units, and a heat pump heating device as heating means for hot water supply installed in a common space And a hot water tank connected to the heat pump heating device and installed in the same common space, and piped from the hot water tank toward a plurality of dwelling units and returned to the hot water tank. A circulation path and a branch pipe that is drawn from the circulation path to each dwelling unit and does not return to the circulation path are provided.
ここで、前記ヒートポンプ式加熱装置及び前記貯湯槽の稼働には共用の電気及び水が使用されるとともに、前記枝管には湯量計が接続される構成とすることができる。 Here, common electricity and water are used for the operation of the heat pump type heating device and the hot water storage tank, and a hot water meter is connected to the branch pipe.
また、給湯用の加熱手段として集熱パイプが配管された集熱器を備えた構成であってもよい。さらに、前記循環経路には保温用の加熱手段が接続されている構成にすることもできる。 Moreover, the structure provided with the heat collector by which the heat collecting pipe was piped as a heating means for hot water supply may be sufficient. Further, a heating means for keeping warm may be connected to the circulation path.
そして、前記共用空間は共用階段に隣接する空間であってもよい。また、複層階の集合建物に適用するに際して、前記循環経路が上層階の床又は下層階の天井に隣接して配管される構成とすることができる。 The shared space may be a space adjacent to a shared staircase. Further, when applied to a multi-storey apartment building, the circulation path may be arranged adjacent to the upper floor or the lower floor ceiling.
このように構成された本発明の給湯システムは、加熱手段としてヒートポンプ式加熱装置を使用している。また、供給されなかった湯を貯湯槽に戻す循環経路を備えるとともに、各住戸へは一方通行で湯が供給される。 The hot water supply system of the present invention configured as described above uses a heat pump heating device as a heating means. Moreover, while providing the circulation path which returns the hot water which was not supplied to a hot water storage tank, hot water is supplied to each dwelling unit by one way.
このため、少ないエネルギーで湯を作ることができるうえに、給湯栓を開けた直後から安定した温度の湯を使用することができる。また、各住戸に引き込まれる枝管は簡素な構成にできるため、配管コストを抑えることができる。 For this reason, hot water can be made with less energy, and hot water at a stable temperature can be used immediately after the hot water tap is opened. Moreover, since the branch pipe drawn into each dwelling unit can be made into a simple structure, piping cost can be held down.
さらに、各住戸の枝管に湯量計を接続することで、各住戸の使用量に応じて料金を徴収できるため、合理的である。また、太陽熱や大気熱を利用する集熱器を接続することによって、電気などのエネルギーの使用量を削減することができる。 Furthermore, it is reasonable to connect a hot water meter to the branch pipe of each dwelling unit so that a charge can be collected according to the usage amount of each dwelling unit. In addition, the amount of energy such as electricity can be reduced by connecting a collector that uses solar heat or atmospheric heat.
そして、循環経路に保温用の加熱手段を接続すれば、少量の湯の加熱にヒートポンプ式加熱装置を稼動させなくてもよくなるため、効率的である。また、共用階段の下や踊り場などの空いているスペースにヒートポンプ式加熱装置及び貯湯槽を設置すれば、空間を有効利用することができる。 If a heating means for heat insulation is connected to the circulation path, the heat pump heating device does not have to be operated for heating a small amount of hot water, which is efficient. Moreover, if a heat pump type heating device and a hot water tank are installed in a vacant space such as under a shared staircase or a landing, the space can be used effectively.
さらに、複層階の集合建物の各階の境界付近に循環経路の配管をおこなえば、上層階及び下層階の住戸までの枝管の長さを短くすることができ、配管コストを抑えることができるうえに、開栓後の短時間で安定した湯を供給できるようになる。 Furthermore, if piping of the circulation route is performed near the boundary of each floor of a multi-storey building, the length of the branch pipes to the upper and lower floor dwelling units can be shortened, and the piping cost can be suppressed. In addition, stable hot water can be supplied in a short time after opening.
以下、本発明の実施の形態について図面を参照して説明する。図１は、集合建物としての集合住宅１０に本実施の形態の給湯システム２を適用した構成を模式的に示した説明図である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram schematically showing a configuration in which the hot water supply system 2 of the present embodiment is applied to an apartment house 10 as an apartment building.
この集合住宅１０は、複層階となる２階建てであり、図１に示すように１階と２階にそれぞれ２戸の住戸１Ａ，１Ｂ，１Ｃ，１Ｄがある。集合住宅１０の外観は、図３によって参照できるように、屋根１３と外壁１２とによって主に形成され、共用階段１６には２階の住戸１Ｃ，１Ｄの玄関に繋がる共用廊下１１が接続される。 The apartment house 10 is a two-story building having multiple floors, and there are two dwelling units 1A, 1B, 1C, and 1D on the first and second floors as shown in FIG. As can be seen from FIG. 3, the appearance of the apartment house 10 is mainly formed by the roof 13 and the outer wall 12. .
そして、集合住宅１０には、図１に示すように、給湯システム２が各住戸１Ａ−１Ｄの給湯設備として設置されている。この給湯システム２は、１台の貯湯式給湯装置３と、その貯湯式給湯装置３から複数の住戸１Ａ−１Ｄに湯を供給するために設けられる循環経路としての循環パイプ４と、循環パイプ４から各住戸１Ａ−１Ｄに引き込まれる枝管５Ａ−５Ｄとを主に備えている。 And in the apartment house 10, as shown in FIG. 1, the hot water supply system 2 is installed as the hot water supply equipment of each dwelling unit 1A-1D. The hot water supply system 2 includes a single hot water storage type hot water supply device 3, a circulation pipe 4 as a circulation path provided for supplying hot water from the hot water storage type hot water supply device 3 to the plurality of dwelling units 1 </ b> A- 1 </ b> D, and the circulation pipe 4. To the respective dwelling units 1A-1D. The branch pipes 5A-5D are mainly provided.
貯湯式給湯装置３は、外壁１２に隣接した共用空間に設置される。また、貯湯式給湯装置３には、各住戸１Ａ−１Ｄからは独立した共用部の水道管１４及び電線１５が接続されている。 The hot water storage type hot water supply device 3 is installed in a common space adjacent to the outer wall 12. Moreover, the hot water storage type hot water supply apparatus 3 is connected with a water pipe 14 and an electric wire 15 of a common part independent of each dwelling unit 1A-1D.
貯湯式給湯装置３は、給湯用の加熱手段としてのヒートポンプ式加熱装置３１と、そのヒートポンプ式加熱装置３１に接続される貯湯槽としての貯湯タンク３２とを主に備えている。 The hot water storage type hot water supply device 3 mainly includes a heat pump type heating device 31 as a heating means for hot water supply and a hot water storage tank 32 as a hot water storage tank connected to the heat pump type heating device 31.
ヒートポンプ式加熱装置３１は、熱を低温物体と高温物体との間で移動させることで加熱をおこなう装置で、二酸化炭素などの熱媒を熱搬送流体として循環させる際に圧縮と膨張を繰り返させることで、大気熱を取り込ませて水の加熱をおこなう。 The heat pump heating device 31 is a device that heats by moving heat between a low temperature object and a high temperature object, and repeats compression and expansion when circulating a heat medium such as carbon dioxide as a heat transfer fluid. Then, the water is heated by taking in atmospheric heat.
すなわち、ヒートポンプ式加熱装置３１を流れる液状の熱媒は、膨張弁（図示省略）で圧力を一気に下げられて低圧・低温状態になって液体のまま外気との熱交換部（図示省略）に搬送される。 That is, the liquid heat medium flowing through the heat pump type heating device 31 is reduced in pressure at a stretch by an expansion valve (not shown), becomes a low pressure / low temperature state, and is transferred to a heat exchanging part (not shown) with the outside air in a liquid state Is done.
そして、熱交換部に搬送された熱媒は、外気と熱交換をおこなうことで温度が上昇して気体になり、気体になった熱媒は、圧縮機（図示省略）内で圧縮されて高圧・高温状態になる。 Then, the heat medium conveyed to the heat exchange unit is heated to gas by exchanging heat with the outside air, and the heat medium turned into gas is compressed in a compressor (not shown) and is pressurized.・ It becomes hot.
このように高温状態になった熱媒が通る管と水が通る管とを接触させて間接的に熱交換をおこなわせることで、水を加熱することができる。他方、熱媒は、この熱交換によって温度が下がって液体になり、再び膨張弁に送られる。 Thus, water can be heated by making the pipe | tube with which the heat medium in a high temperature state passes, and the pipe | tube with which water passes are made to perform heat exchange indirectly. On the other hand, the temperature of the heat medium decreases due to this heat exchange and becomes liquid, and is sent to the expansion valve again.
ヒートポンプ式加熱装置３１の成績係数（ＣＯＰ）は、「放出する熱量」を「熱媒を圧縮する圧縮機を作動させる電力」で除した値であり、放出する熱量が多いほど成績係数（ＣＯＰ）は大きくなってエネルギー効率が良いとされる。 The coefficient of performance (COP) of the heat pump type heating device 31 is a value obtained by dividing “amount of heat released” by “electric power for operating the compressor that compresses the heat medium”, and the coefficient of performance (COP) increases as the amount of released heat increases. Is said to be large and energy efficient.
このように共用部の水と電気を使ってヒートポンプ式加熱装置３１によって作られた湯は、貯湯タンク３２に貯められる。なお、この貯湯タンク３２に貯める湯は、電気料金の安い深夜電力を使って作られる。 Thus, the hot water produced by the heat pump type heating device 31 using the water and electricity in the common area is stored in the hot water storage tank 32. The hot water stored in the hot water storage tank 32 is made using late-night power with a low electricity charge.
この貯湯タンク３２には、各住戸１Ａ−１Ｄに向けて配管されるとともに供給されなかった湯を貯湯タンク３２に戻すための循環パイプ４が接続される。すなわち、循環パイプ４の一端は貯湯タンク３２の上部に接続され、そこから往路管４１が２階の共用廊下１１に向けて延伸される。 The hot water storage tank 32 is connected to a circulation pipe 4 that is piped toward the dwelling units 1A to 1D and returns hot water that has not been supplied to the hot water storage tank 32. That is, one end of the circulation pipe 4 is connected to the upper part of the hot water storage tank 32, and the outgoing pipe 41 is extended from there toward the shared hallway 11 on the second floor.
また、共用廊下１１を通って各住戸１Ａ−１Ｄの近傍を通過した循環パイプ４の復路管４２の端部は、貯湯タンク３２に接続される。この復路管４２が接続される位置は、循環パイプ４が保温用の加熱手段を備えているか否かなどの諸条件によって変わる。 Further, the end of the return pipe 42 of the circulation pipe 4 that has passed through the common hallway 11 and in the vicinity of each dwelling unit 1 </ b> A- 1 </ b> D is connected to the hot water storage tank 32. The position where the return pipe 42 is connected varies depending on various conditions such as whether or not the circulation pipe 4 is provided with heating means for keeping warm.
すなわち、保温用の加熱手段によって循環パイプ４の搬送中に低下した温度を上昇させる場合は、貯湯タンク３２の温度の高い上部に湯を戻すことができる。他方、保温用の加熱手段がなく、循環パイプ４の搬送中の温度低下が大きい場合は、貯湯タンク３２の中央より下方の比較的温度が低い湯が貯まっている下部に湯を戻すことになる。 That is, when the temperature lowered during the conveyance of the circulation pipe 4 is raised by the heating means for keeping warm, the hot water can be returned to the upper part of the hot water storage tank 32 where the temperature is high. On the other hand, when there is no heating means for heat insulation and the temperature drop during the conveyance of the circulation pipe 4 is large, the hot water is returned to the lower part where hot water having a relatively low temperature is stored below the center of the hot water storage tank 32. .
また、循環パイプ４には循環ポンプ（図示省略）が接続されており、住戸１Ａ−１Ｄで湯が使用されていないときも含めて、常時、循環パイプ４には湯が循環している。この循環ポンプに上述した保温用の加熱手段を設けることができる。 Further, a circulation pump (not shown) is connected to the circulation pipe 4, and the hot water circulates in the circulation pipe 4 at all times, including when hot water is not used in the dwelling units 1A to 1D. The circulation pump can be provided with the above-described heating means for keeping warm.
さらに、共用廊下１１に配管された循環パイプ４には、各住戸１Ａ−１Ｄ用の枝管５Ａ−５Ｄが接続される。これらの枝管５Ａ−５Ｄは、各住戸１Ａ−１Ｄに向けて一方通行の流れとなるような配管にされるもので、使用しなかった湯を循環パイプ４に戻す経路は設けられない。 Further, branch pipes 5A-5D for each dwelling unit 1A-1D are connected to the circulation pipe 4 piped in the common hallway 11. These branch pipes 5A-5D are piped so as to be a one-way flow toward each dwelling unit 1A-1D, and a path for returning unused hot water to the circulation pipe 4 is not provided.
循環パイプ４からは、１階の住戸１Ａ，１Ｂには天井側から枝管５Ａ，５Ｂの配管がされる。また、２階の住戸１Ｃ，１Ｄには、床に沿って枝管５Ｃ，５Ｄの配管がされる。 From the circulation pipe 4, branch pipes 5 </ b> A and 5 </ b> B are piped from the ceiling side to the dwelling units 1 </ b> A and 1 </ b> B on the first floor. Further, branch pipes 5C and 5D are piped along the floor in the dwelling units 1C and 1D on the second floor.
このように循環パイプ４を１階と２階の境界に隣接する共用廊下１１に配管すれば、１階の廊下に配管した後に２階の廊下に配管させる場合に比べて、循環パイプ４の総延長を短くすることができる。このため、循環パイプ４の搬送中の熱損失を減らすことができる。 In this way, if the circulation pipe 4 is piped in the common hallway 11 adjacent to the boundary between the first floor and the second floor, the total number of the circulation pipes 4 is larger than that in the case where the pipe is piped in the hallway on the second floor after being piped in the hallway on the first floor. Extension can be shortened. For this reason, the heat loss during conveyance of the circulation pipe 4 can be reduced.
また、循環パイプ４が１階と２階の境界付近に配管されていれば、１階の住戸１Ａ，１Ｂにも２階の住戸１Ｃ，１Ｄにも近くなるので、それぞれの枝管５Ａ−５Ｄの長さを短くできる。 Further, if the circulation pipe 4 is arranged near the boundary between the first floor and the second floor, the branch pipes 5A-5D are close to the first floor dwelling units 1A and 1B and the second floor dwelling units 1C and 1D. Can be shortened.
そして、これらの枝管５Ａ−５Ｄには、通過する湯量を計測するための湯量計６Ａ−６Ｄをそれぞれ取り付ける。ここで、枝管５Ａ−５Ｄを通過した湯は、循環パイプ４に戻ることがないため、湯量計６Ａ−６Ｄは、枝管５Ａ−５Ｄの引込口の一箇所にそれぞれ設ければよい。 And the hot water meter 6A-6D for measuring the amount of hot water to pass through is attached to these branch pipes 5A-5D, respectively. Here, since the hot water that has passed through the branch pipes 5A-5D does not return to the circulation pipe 4, the hot water meter 6A-6D may be provided at one place of the inlet of the branch pipes 5A-5D.
貯湯タンク３２の湯は共用部の水と電気を使って作られるため、各枝管５Ａ−５Ｄに湯量計６Ａ−６Ｄがなければ、湯の使用量を徴収しないか、又は各住戸１Ａ−１Ｄの均一料金にするしかない。 Since the hot water in the hot water storage tank 32 is made using water and electricity in the common area, if there is no hot water meter 6A-6D in each branch pipe 5A-5D, the amount of hot water used is not collected or each dwelling unit 1A-1D. There is no choice but to make a flat fee.
これに対して各枝管５Ａ−５Ｄに湯量計６Ａ−６Ｄを接続して各住戸１Ａ−１Ｄの湯の使用量が明確にできれば、使った分に応じた従量制の料金体系を採用することができる。この湯量計６Ａ−６Ｄは、目視によって読み取る構成であってもよいし、遠隔で計測値を集計できる構成であってもよい。 On the other hand, if a hot water meter 6A-6D is connected to each branch pipe 5A-5D and the amount of hot water used in each dwelling unit 1A-1D can be clarified, a pay-as-you-go system based on the amount used will be adopted. Can do. This hot water meter 6A-6D may be configured to be read visually, or may be configured to be able to tabulate measured values remotely.
次に、本実施の形態の給湯システム２の作用について説明する。 Next, the effect | action of the hot water supply system 2 of this Embodiment is demonstrated.
このように構成された本実施の形態の給湯システム２は、加熱手段としてヒートポンプ式加熱装置３１を使用している。また、供給されなかった湯を貯湯タンク３２に戻す循環パイプ４を備えるとともに、各住戸１Ａ−１Ｄへは枝管５Ａ−５Ｄを通して一方通行で湯が供給される。 The hot water supply system 2 of the present embodiment configured as described above uses a heat pump heating device 31 as a heating means. Moreover, the circulation pipe 4 which returns the hot water which was not supplied to the hot water storage tank 32 is provided, and hot water is supplied to each dwelling unit 1A-1D through the branch pipes 5A-5D by one way.
すなわち、エネルギー効率のよいヒートポンプ式加熱装置３１によって、少ないエネルギーで湯を作ることができる。また、複数の住戸１Ａ−１Ｄに対して１台の貯湯式給湯装置３を設置すればよいので、設置スペースが少なくて済む。 That is, hot water can be made with less energy by the heat pump type heating device 31 with good energy efficiency. Moreover, since one hot water storage type hot water supply device 3 may be installed for the plurality of dwelling units 1A-1D, the installation space is small.
さらに、各住戸１Ａ−１Ｄに給湯装置を設置する場合は、住戸の数だけ高価なヒートポンプ式加熱装置が必要になりコストが嵩むうえに作動時の騒音も各所で発生することになるが、それに比べて１台の貯湯式給湯装置３を複数の住戸１Ａ−１Ｄで使用する構成とすることでコストや騒音を抑えることができる。 Furthermore, when installing a hot water supply device in each dwelling unit 1A-1D, a heat pump type heating device that is as expensive as the number of dwelling units is required, which increases costs and generates noise during operation. In comparison, cost and noise can be reduced by using a single hot water storage type hot water supply device 3 in a plurality of dwelling units 1A-1D.
また、循環パイプ４によって各住戸１Ａ−１Ｄ近くまで常時、湯が搬送されているため、各住戸１Ａ−１Ｄでは給湯栓を開けた直後から安定した温度の湯を使用することができる。 Moreover, since hot water is always conveyed to the vicinity of each dwelling unit 1A-1D by the circulation pipe 4, each dwelling unit 1A-1D can use hot water having a stable temperature immediately after opening the hot water tap.
すなわち、循環パイプ４を流れる湯は、常に安定した温度を保っているので、給湯栓を開けて枝管５Ａ−５Ｄ内の湯が排出されれば、すぐに安定した温度の湯が供給されることになる。 That is, since the hot water flowing through the circulation pipe 4 always maintains a stable temperature, when the hot water tap is opened and the hot water in the branch pipes 5A-5D is discharged, the hot water having a stable temperature is immediately supplied. It will be.
そして、２階建ての集合住宅１０の１階と２階の境界付近にある共用廊下１１に循環パイプ４の配管をおこなえば、２階及び１階の住戸１Ａ−１Ｄまでの枝管５Ａ−５Ｄの長さを短くすることができ、冷めた湯が管内に貯留される量も少なくなるので、開栓後の短時間で安定した温度の湯を供給できるようになる。 Then, if the circulation pipe 4 is piped in the common corridor 11 near the boundary between the first floor and the second floor of the two-story apartment building 10, the branch pipes 5A-5D up to the second floor and the first floor dwelling units 1A-1D. Since the amount of cold hot water stored in the pipe is reduced, it becomes possible to supply hot water at a stable temperature in a short time after opening.
また、枝管５Ａ−５Ｄが短ければ、配管コストを抑えることができる。さらに、各住戸１Ａ−１Ｄに引き込まれる枝管５Ａ−５Ｄは、循環をさせない簡素な構成にできるため、配管のための材料費や配管作業などのコストを抑えることができる。 Moreover, if branch pipe 5A-5D is short, piping cost can be held down. Further, the branch pipes 5A-5D drawn into the respective dwelling units 1A-1D can have a simple configuration that does not circulate, so that costs such as material costs for piping and piping work can be suppressed.
また、各住戸１Ａ−１Ｄの枝管５Ａ−５Ｄに湯量計６Ａ−６Ｄを接続することで、各住戸１Ａ−１Ｄの使用量に応じて料金を徴収できるため、合理的である。 In addition, it is reasonable to connect the hot water meter 6A-6D to the branch pipes 5A-5D of each dwelling unit 1A-1D, so that charges can be collected according to the usage amount of each dwelling unit 1A-1D.
さらに、循環パイプ４に保温用の加熱手段を接続することによって、少量の湯の加熱にヒートポンプ式加熱装置３１を稼動させなくてもよくなるため、効率的である。 Furthermore, by connecting a heating means for heat insulation to the circulation pipe 4, it is not necessary to operate the heat pump heating device 31 for heating a small amount of hot water, which is efficient.
以下、前記した実施の形態で説明した給湯システム２とは別の形態の給湯システム２Ａについて、図２，３を参照しながら説明する。なお、前記実施の形態で説明した内容と同一乃至均等な部分の説明については、同一用語や同一符号を付して説明する。 Hereinafter, a hot water supply system 2A different from the hot water supply system 2 described in the above embodiment will be described with reference to FIGS. Note that the description of the same or equivalent parts as those described in the above embodiment will be described with the same terms and the same reference numerals.
この実施例で説明する給湯システム２Ａには、集熱器としての太陽熱集熱器７が接続されている。太陽熱集熱器７は、給湯用の加熱手段として設置され、貯湯式給湯装置３Ａに接続される。 A solar heat collector 7 serving as a heat collector is connected to the hot water supply system 2A described in this embodiment. The solar heat collector 7 is installed as a heating means for hot water supply, and is connected to the hot water storage type hot water supply apparatus 3A.
太陽熱集熱器７は、内部に集熱パイプ（図示省略）が蛇行して配管されている。この太陽熱集熱器７は集合住宅１０の屋根１３の上に設置され、太陽熱や大気熱によって温められた集熱パイプ内部の水が接続管７１を通って貯湯式給湯装置３Ａに流れ込む。 The solar heat collector 7 is provided with a heat collecting pipe (not shown) meandering inside. The solar heat collector 7 is installed on the roof 13 of the apartment house 10, and the water inside the heat collection pipe heated by solar heat or atmospheric heat flows into the hot water storage hot water supply device 3 </ b> A through the connection pipe 71.
このように水道管１４から供給される水の温度を太陽熱集熱器７によって上昇させる構成とすることで、ヒートポンプ式加熱装置３１の負荷を減らすことができれば、電気エネルギーの使用量を削減することができる。 Thus, if the load of the heat pump type heating device 31 can be reduced by adopting a configuration in which the temperature of the water supplied from the water pipe 14 is raised by the solar heat collector 7, the amount of electric energy used can be reduced. Can do.
また、この実施例の貯湯式給湯装置３Ａは、図３に示すように、集合住宅１０の共用空間にある共用階段１６の下方空間に設置される。この図３では、共用階段１６の下方空間に、１台のヒートポンプ式加熱装置３１と２台の貯湯タンク３２，３２とが収容されている。 Moreover, the hot water storage type hot water supply apparatus 3A of this embodiment is installed in a space below the common staircase 16 in the common space of the apartment house 10, as shown in FIG. In FIG. 3, one heat pump type heating device 31 and two hot water storage tanks 32 and 32 are accommodated in the space below the shared staircase 16.
共用階段１６の下方空間のように空いているスペースにヒートポンプ式加熱装置３１及び貯湯タンク３２を設置できれば、空間を有効利用することができる。 If the heat pump type heating device 31 and the hot water storage tank 32 can be installed in an empty space such as the space below the common staircase 16, the space can be used effectively.
また、各住戸１Ａ−１Ｄから比較的に離れた場所に設けられる共用階段１６に隣接して貯湯式給湯装置３Ａを設置すれば、稼動時の騒音も気にならなくなる。 Moreover, if the hot water storage type hot water supply device 3A is installed adjacent to the shared staircase 16 provided at a location relatively distant from each of the dwelling units 1A-1D, noise during operation will not be bothered.
