A heat pump cycle X is configured. The radiator 4A and the heat receiver 4B are integrated with each other to constitute a refrigerant-to-water heat exchanger 4 as a heating device.

前記貯湯タンクユニット2は、タンク側外装ケース2A内に、ステンレス鋼板製の縦長な貯湯タンク12、給水配管13、給水開閉弁14、分岐給水配管15、貯湯用配管16、貯湯用循環ポンプ17、追い焚き用配管18、追い焚き用熱交換器19、風呂水用配管20、風呂水用循環ポンプ21、追い焚き用循環ポンプ22、給湯用配管23、混合弁装置24、風呂給湯開閉弁25、タンク側制御装置26等を収容している。   The hot water storage tank unit 2 has a vertically long hot water storage tank 12 made of a stainless steel plate, a water supply pipe 13, a water supply on / off valve 14, a branch water supply pipe 15, a hot water storage pipe 16, a hot water circulation pump 17, in a tank side outer case 2A. Reheating pipe 18, reheating heat exchanger 19, bath water pipe 20, bath water circulation pump 21, reheating circulation pump 22, hot water supply pipe 23, mixing valve device 24, bath hot water on / off valve 25, The tank side control device 26 and the like are accommodated.

前記給水配管13及び貯湯用配管16の出口部16Aが前記貯湯タンク12の底部に接続され、貯湯用配管16の入口部16B、追い焚き用配管18の出口部18A及び給湯用配管23がそれぞれ前記貯湯タンク12の頂部に接続されている。   The outlet 16A of the water supply pipe 13 and the hot water storage pipe 16 is connected to the bottom of the hot water storage tank 12, and the inlet part 16B of the hot water storage pipe 16, the outlet part 18A of the reheating pipe 18 and the hot water supply pipe 23 are respectively described above. It is connected to the top of the hot water storage tank 12.

27は前記ヒートポンプ側制御装置8とタンク側制御装置26とを配線接続する通信線、28は台所用リモートコントローラ、29は風呂用リモートコントローラであり、これら各リモートコントローラ28、29はタンク側制御装置26に配線接続されている。30は風呂を示している。   27 is a communication line for wiring connection between the heat pump side control device 8 and the tank side control device 26, 28 is a kitchen remote controller, 29 is a bath remote controller, and these remote controllers 28 and 29 are tank side control devices. 26 is connected by wiring. 30 indicates a bath.

ここで、台所などに設置してある蛇口(図示せず)を開けると、貯湯タンク12内上部の高温の湯が水道圧で給湯用配管23へ押し出され、給湯が行われると同時に、貯湯タンク12内下部には、底部に接続された水道配管13から水道水が給水される。   Here, when a faucet (not shown) installed in the kitchen or the like is opened, the hot water in the upper part of the hot water storage tank 12 is pushed out to the hot water supply pipe 23 by water pressure, and at the same time as hot water is supplied, Tap water is supplied to the lower part in 12 from a water pipe 13 connected to the bottom.

風呂30に注湯する湯張りを行う場合は、風呂用リモートコントローラ29の風呂湯張りスイッチ(図示せず)を押すと、貯湯タンク12内上部から給湯用配管23へ押し出された高温の湯が混合弁装置24へ流れ、ここで分岐給水管15から給水される水と混合されて、予め設定された温度の湯が風呂30へ注湯され、所定の湯量が注湯されると湯張りが完了する。この風呂30の湯張り時にも、湯張り運転の開始と同時に、貯湯タンク12内下部には、底部に接続された水道配管13から水道水が給水される。   When filling the bath 30 with hot water, if a bath hot water switch (not shown) of the remote controller 29 for bath is pressed, hot water pushed out from the upper part of the hot water storage tank 12 to the hot water supply pipe 23 is heated. It flows to the mixing valve device 24, where it is mixed with water supplied from the branch water supply pipe 15, hot water having a preset temperature is poured into the bath 30, and when a predetermined amount of hot water is poured, Complete. Even when the bath 30 is filled, tap water is supplied to the lower part of the hot water storage tank 12 from the water pipe 13 connected to the bottom at the same time as the start of the filling operation.

上記したように台所や風呂30などの利用部への給湯が行われると、貯湯タンク12内の高温の湯が消費され、貯湯タンク12内における高温の湯の層が減少し、この高温の湯は貯湯タンク12内の上部にのみ貯留し、貯湯タンク12内の中間部や下部は、温度の低い湯或いは水が貯留された状態となる。   As described above, when hot water is supplied to a use section such as the kitchen or the bath 30, the hot water in the hot water storage tank 12 is consumed, and the hot water layer in the hot water storage tank 12 is reduced. Is stored only in the upper part of the hot water storage tank 12, and the intermediate part and the lower part of the hot water storage tank 12 are in a state where hot water or water having a low temperature is stored.

次に、お湯の沸き上げ運転について説明する。ヒートポンプユニット1の運転開始により、ヒートポンプサイクルXの圧縮機3が起動すると、二酸化炭素の冷媒が圧縮機3によって2段圧縮され、この圧縮機3で圧縮されて吐出した超臨界圧の高温・高圧の液状の冷媒は放熱器4Aで放熱して受熱器4Bを流れる水と熱交換し、その水を加熱する。   Next, hot water boiling operation will be described. When the compressor 3 of the heat pump cycle X is started by starting the operation of the heat pump unit 1, the carbon dioxide refrigerant is compressed in two stages by the compressor 3, and is compressed and discharged by the compressor 3. The liquid refrigerant radiates heat with the radiator 4A, exchanges heat with water flowing through the heat receiver 4B, and heats the water.

前記放熱器4Aで放熱して温度の低下した冷媒は、減圧装置5で減圧されて低圧となった後、蒸発器6に流れ、蒸発器6で空気から吸熱して蒸発し、低温・低圧のガス状の冷媒となり、アキュームレータ7に流れ、このアキュームレータ7から圧縮機3に吸入され再び圧縮される。   The refrigerant whose temperature has been reduced by releasing heat from the radiator 4A is reduced in pressure by the decompression device 5 and becomes low pressure, and then flows into the evaporator 6 and is evaporated by absorbing heat from the air in the evaporator 6. It becomes a gaseous refrigerant, flows into the accumulator 7, is sucked into the compressor 3 from the accumulator 7, and is compressed again.

上述のヒートポンプユニット1の運転開始に伴い、貯湯タンクユニット2内の貯湯用循環ポンプ17が起動し、この循環ポンプ17の運転により、前記貯湯タンク12内下部の低温或いは常温の水が、貯湯用配管16の出口部16Aから貯湯用配管16内へ流れ、貯湯用循環ポンプ17を介して受熱器4Bへ流れ、ここで前記放熱器4Aを流れる高温・高圧の冷媒と熱交換して加熱される。そして、この受熱器4Bで加熱された高温の湯は前記入口部16Bから貯湯タンク12内の上部に流入し、沸き上げ運転の時間の経過に伴って、貯湯タンク12内には80℃以上の湯の貯留量が徐々に増加し、この高温の湯の湯層が貯湯タンク12内の下部に至ると沸き上げ運転が完了する。   With the start of operation of the heat pump unit 1, the hot water circulation pump 17 in the hot water storage tank unit 2 is activated, and the operation of the circulation pump 17 causes the low or normal temperature water in the lower part of the hot water storage tank 12 to be used for hot water storage. It flows into the hot water storage pipe 16 from the outlet 16A of the pipe 16, flows into the heat receiver 4B through the hot water circulation pump 17, and is heated by exchanging heat with the high-temperature and high-pressure refrigerant flowing through the radiator 4A. . And the hot water heated by this heat receiver 4B flows into the upper part of the hot water storage tank 12 from the said inlet part 16B, and 80 degreeC or more is contained in the hot water storage tank 12 with progress of the time of boiling operation. When the hot water storage amount gradually increases and the hot water layer reaches the lower part of the hot water storage tank 12, the boiling operation is completed.

次に、図3〜図5を用いて貯湯タンク12の断熱構造について説明する。前記貯湯タンク12は、それの上部の外郭が上部発泡性成形断熱材32により被覆され、一方、下部の外郭が下部発泡性成形断熱材33により被覆されている。そして、貯湯タンク12は、前記上部と下部の発泡性成形断熱材32、33により被覆されていない残余部分の外郭、即ち、中間部の外郭が、その中間部に巻き付けられるグラスウール製の面状断熱材34で被覆されている。35、35は貯湯タンク12の下部に設けられた複数の支持脚である。   Next, the heat insulation structure of the hot water storage tank 12 will be described with reference to FIGS. The hot water storage tank 12 has an upper outer shell covered with an upper foamable heat insulating material 32, while a lower outer shell is covered with a lower foamable heat insulating material 33. The hot water storage tank 12 is made of glass wool sheet heat insulation in which the outer portion of the remaining portion that is not covered by the upper and lower foamable heat insulating materials 32 and 33, that is, the outer portion of the intermediate portion is wound around the intermediate portion. It is covered with a material 34. Reference numerals 35 and 35 denote a plurality of support legs provided at the lower part of the hot water storage tank 12.

前記上部と下部の発泡性成形断熱材32、33は、耐熱性発泡ポリスチレンを成形金型により成形加工したものであり、前記貯湯タンク12の上部と下部の外郭に合わせた形状の窪み部32B、33Bをそれぞれ有し、その窪み部32B、33Bに貯湯タンク12の上部と下部を嵌合させて、貯湯タンク12に取り付けるものである。   The upper and lower foamable heat-insulating materials 32 and 33 are formed by molding heat-resistant foamed polystyrene with a molding die, and the recessed portions 32B having a shape matching the outer and upper outlines of the hot water storage tank 12 are provided. 33B is provided, and the upper part and the lower part of the hot water storage tank 12 are fitted to the depressions 32B and 33B, and the hot water storage tank 12 is attached.

また、前記上部発泡性成形断熱材32には、貯湯タンク12の頂部に接続された給湯用配管16や追い焚き用配管18などの配管を導出させる導出用開口部32Aが形成され、この導出用開口部32Aには配管を導出させた状態で、その導出用開口部32Aを塞ぐ隙間パット36を嵌合装着する。   The upper foaming molded heat insulating material 32 is formed with a lead-out opening 32A through which pipes such as the hot water supply pipe 16 and the reheating pipe 18 connected to the top of the hot water storage tank 12 are led out. In the state where the piping is led out to the opening 32A, a gap pad 36 for closing the leading opening 32A is fitted and mounted.

前記面状断熱材34は、図3に示すように、貯湯タンク12に巻き付けた後に金属線材などの締着具37、37を用いて、巻き付け装着状態を保持している。また、この面状断熱材34は、図5に示すように、グラスウール材34Aが軟質樹脂シートの袋体34Bに収容されており、グラスウールによる作業者への弊害を抑え、取り扱いを容易としている。前記軟質樹脂シートとしては、耐熱性のポリスチレンシート等が用いられている。   As shown in FIG. 3, the planar heat insulating material 34 is wrapped around the hot water storage tank 12 and then held in a wound state using fasteners 37, 37 such as a metal wire. Further, as shown in FIG. 5, the planar heat insulating material 34 includes a glass wool material 34A accommodated in a bag body 34B of a soft resin sheet, which suppresses harmful effects caused by glass wool on the operator and facilitates handling. As the soft resin sheet, a heat resistant polystyrene sheet or the like is used.

更に、前記面状断熱材34には、反射膜38が付設されている。この反射膜38は、アルミニウム蒸着シートで形成され、前記袋体34Bの一面の略全体に貼り付けて、貯湯タンク12からの放射熱を貯湯タンク12側へ反射させて、保温・断熱性を一層高めている。   Further, a reflective film 38 is attached to the planar heat insulating material 34. The reflective film 38 is formed of an aluminum vapor deposition sheet, and is attached to substantially the entire surface of the bag body 34B to reflect the radiant heat from the hot water storage tank 12 to the hot water storage tank 12 side, thereby further improving heat insulation and heat insulation. It is increasing.

上述の実施例によれば、給水配管13、貯湯用配管16、追い焚き用配管18及び給湯用配管23を含む複数の配管が接続され、加熱装置としてのヒートポンプサイクルXの冷媒対水熱交換器4で加熱された湯を貯留する貯湯タンク12を備えたヒートポンプ式の給湯装置Aにおいて、貯湯タンク12は、上部及び下部の外郭がそれぞれ上部と下部の発泡性成形断熱材32、33により被覆されると共に、この上部と下部の発泡性成形断熱材32、33により被覆されていない残余の外郭が巻き付けによるグラスウール製の面状断熱材34で被覆されている構成であるから、常時、80℃以上の高温の湯が貯留される貯湯タンク12の上部が、型成形された上部発泡性成形断熱材32で覆われ、また、貯湯タンク12の中間部がグラスウール製の面状断熱材34で覆われる構成であるから、高温部である貯湯タンク12上部の放熱ロスが、保温・断熱性に優れた型成形の上部発泡性成形断熱材32で抑制され、貯湯タンク12の中間部の放熱ロスが面状断熱材34で抑えられ、貯湯タンク12の保温・断熱性を維持しつつ、型成形による発泡性成形断熱材でのタンク被覆面積を半減できると共に、発泡性成形断熱材の使用数も半減できるなど、発泡性成形断熱材の成形金型の小型化やセット数の削減が図れ、投資コストを抑えながら、断熱構造の作業性に優れ、しかも、十分な保温・断熱効果の得られる給湯装置の貯湯タンクと成せる。   According to the above-described embodiment, a plurality of pipes including the water supply pipe 13, the hot water storage pipe 16, the reheating pipe 18 and the hot water supply pipe 23 are connected, and the refrigerant-to-water heat exchanger of the heat pump cycle X as a heating device is connected. In the heat pump type hot water supply apparatus A having the hot water storage tank 12 for storing the hot water heated in 4, the upper and lower outer shells of the hot water storage tank 12 are covered by the upper and lower foamable heat insulating materials 32 and 33, respectively. The upper and lower foamed heat insulating materials 32 and 33 are not covered by the remaining outer shell and are covered with a glass wool sheet heat insulating material 34, so that the temperature is always 80 ° C. or higher. The upper part of the hot water storage tank 12 in which hot water is stored is covered with a molded upper foaming heat insulating material 32, and the intermediate part of the hot water storage tank 12 is glass wool. Therefore, the heat dissipation loss at the upper part of the hot water storage tank 12, which is a high temperature part, is suppressed by the mold-formed upper foaming heat insulating material 32 having excellent heat insulation and heat insulation properties. The heat dissipation loss in the middle portion of the heat sink 12 is suppressed by the planar heat insulating material 34, while maintaining the heat insulation and heat insulating properties of the hot water storage tank 12, the tank covering area of the foamable heat insulating material by molding can be halved and the foaming property can be reduced. The number of molded insulation materials can be halved, and the mold of foamable insulation materials can be reduced in size and the number of sets can be reduced. -It can be used as a hot water storage tank for a hot water supply device that can provide heat insulation.

また、前記グラスウール製の面状断熱材34は、グラスウール材34Aが軟質樹脂シートの袋体34Bに収容されているため、グラスウールによる作業者へのカユミやチクチク感などの弊害を抑え、取り付け作業時の取り扱い性を向上できる。   Further, since the glass wool material 34A is accommodated in the soft resin sheet bag 34B, the glass wool sheet-like heat insulating material 34 suppresses harmful effects such as scabs and tingling to the worker due to glass wool, and is attached at the time of installation work. Can be improved.
