The present invention relates to a hot water storage hot water heater that performs heating and drying.

図１１は、従来の給湯式給湯暖房装置１の全体構成を示す模式図である。従来の装置では、一般的に図１１に示すような回路で給湯暖房が行われている。まず、給湯用の高温水を貯湯する貯湯タンク７と、冷媒圧縮機２・冷媒水熱交換器３・膨張弁４および冷媒空気熱交換器５を有する冷媒回路Ｒを備えたヒートポンプ熱源機１ａとが有り、給湯水加熱回路Ｋ１にて貯湯タンク７の下部から取り出した低温水をヒートポンプ熱源機１ａによって沸き上げ、その沸き上げた高温水を貯湯タンク７の上部に戻して貯えると共に、その高温水を用いて給湯を行っている。   FIG. 11 is a schematic diagram showing an overall configuration of a conventional hot water supply type hot water supply / room heating device 1. In a conventional apparatus, hot water supply / heating is generally performed in a circuit as shown in FIG. First, a hot water storage tank 7 for storing hot water for hot water supply, a heat pump heat source machine 1a having a refrigerant circuit R having a refrigerant compressor 2, a refrigerant water heat exchanger 3, an expansion valve 4 and a refrigerant air heat exchanger 5, The low temperature water taken out from the lower part of the hot water storage tank 7 by the hot water supply heating circuit K1 is boiled by the heat pump heat source unit 1a, and the high temperature water thus boiled is returned to the upper part of the hot water storage tank 7 and stored. Hot water is supplied using

また８は、高温水を１次側８ａに流通させて２次側８ｂのブラインを加熱する水ブライン熱交換器であり、ブライン加熱回路Ｋ２にて貯湯タンク７の上部から取り出した高温水を水ブライン熱交換器８に流通させた後、貯湯タンク７の下部に戻している。そして、ブライン循環回路Ｂｊにて水ブライン熱交換器８でて加熱されたブラインを暖房器１０との間で循環させて暖房や乾燥などを行っている。   Reference numeral 8 denotes a water brine heat exchanger for circulating high temperature water to the primary side 8a to heat the brine on the secondary side 8b. The high temperature water taken out from the upper part of the hot water storage tank 7 by the brine heating circuit K2 is water. After being circulated through the brine heat exchanger 8, it is returned to the lower part of the hot water storage tank 7.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram illustrating an overall configuration of a hot water storage type hot water supply / room heating device 1 according to a first embodiment of the present invention. The hot water storage hot water heater 1 in the present embodiment uses hot water while heating hot water while heating and storing hot water to a high temperature (about 90 ° C. in the present embodiment) using a supercritical heat pump cycle. Then, a brine such as an antifreeze liquid serving as a heat exchange medium is heated to an intermediate temperature (40 to 60 ° C. in this embodiment), and the brine is used for heating in a house, for example, floor heating.

尚、超臨界ヒートポンプサイクルとは、高圧側の冷媒圧力が冷媒の臨界圧力以上となるヒートポンプサイクルを言い、例えば二酸化炭素・エチレン・エタン・酸化窒素などを冷媒とするヒートポンプサイクルである。給湯装置１は大きく分けて、主に後述する冷凍サイクル機器が収納されたヒートポンプ熱源機１ａと、主に貯湯タンク７が収納されたタンクユニット１ｂと、当実施例の場合は床暖房ユニット１ｃとよりなる。   The supercritical heat pump cycle refers to a heat pump cycle in which the refrigerant pressure on the high pressure side is equal to or higher than the critical pressure of the refrigerant. For example, the heat pump cycle uses carbon dioxide, ethylene, ethane, nitrogen oxide or the like as the refrigerant. The hot water supply apparatus 1 is roughly divided into a heat pump heat source machine 1a in which mainly refrigeration cycle equipment, which will be described later, is housed, a tank unit 1b in which mainly a hot water storage tank 7 is housed, and a floor heating unit 1c in this embodiment. It becomes more.

また、ヒートポンプ熱源機１ａ内は、大きく分けてヒートポンプサイクルの冷媒回路Ｒと、給湯関係の給湯水加熱回路Ｋ１とで構成されている。まず冷媒回路Ｒは、冷媒を圧縮する冷媒圧縮機２と、給湯用水の加熱手段である冷媒水熱交換器３と、冷媒減圧手段である膨張弁４と、大気から吸熱するための冷媒空気熱交換器５とを環状に接続して構成され、冷媒として臨界温度の低い二酸化炭素（ＣＯ２）が封入されている。 The heat pump heat source unit 1a is roughly divided into a refrigerant circuit R for a heat pump cycle and a hot water supply heating circuit K1 for hot water supply. First, the refrigerant circuit R includes a refrigerant compressor 2 that compresses refrigerant, a refrigerant water heat exchanger 3 that is a heating means for hot water supply, an expansion valve 4 that is a refrigerant decompression means, and refrigerant air heat that absorbs heat from the atmosphere. The exchanger 5 is connected in a ring shape, and carbon dioxide (CO 2 ) having a low critical temperature is enclosed as a refrigerant.

冷媒圧縮機２は、内蔵する駆動モータと、吸引したガス冷媒を臨界圧力以上の高圧にまで昇圧して吐出する高圧圧縮部とで構成しており、これらが密閉容器内に収納されている。そして、装置全体の制御手段である制御装置３０により通電制御される。冷媒水熱交換器３は、高圧圧縮部で昇圧された高温高圧のガス冷媒と給湯用水とを熱交換して給湯用水を加熱するもので、高圧冷媒通路３ａに隣接して給湯水通路３ｂが設けられ、その高圧冷媒通路３ａを流れる冷媒の流れ方向と給湯水通路３ｂを流れる給湯用水の流れ方向とが対向するように構成されている。   The refrigerant compressor 2 includes a built-in drive motor and a high-pressure compressor that discharges the sucked gas refrigerant to a high pressure equal to or higher than the critical pressure, and these are housed in a sealed container. The energization is controlled by the control device 30 which is a control means of the entire device. The refrigerant water heat exchanger 3 heats hot water by exchanging heat between the high-temperature and high-pressure gas refrigerant boosted by the high-pressure compressor and the hot-water supply water. The hot-water supply passage 3b is adjacent to the high-pressure refrigerant passage 3a. The flow direction of the refrigerant flowing through the high-pressure refrigerant passage 3a is opposed to the flow direction of hot water flowing through the hot water supply passage 3b.

膨張弁４は、冷媒水熱交換器３と冷媒空気熱交換器５との間に設けられ、冷媒水熱交換器３で冷却された冷媒を高圧から低圧まで減圧して冷媒空気熱交換器５に供給する。また、この膨張弁４は、弁開度を電気的に調整可能な構成を有し、制御装置３０により通電制御される。冷媒空気熱交換器５は、図示しない送風ファンによる送風を受けて、膨張弁４で減圧された冷媒を大気との熱交換によって蒸発させ、ガスとなった冷媒は先の冷媒圧縮機２に吸引される。   The expansion valve 4 is provided between the refrigerant water heat exchanger 3 and the refrigerant air heat exchanger 5, and depressurizes the refrigerant cooled by the refrigerant water heat exchanger 3 from high pressure to low pressure. To supply. The expansion valve 4 has a configuration in which the valve opening degree can be electrically adjusted, and is energized and controlled by the control device 30. The refrigerant air heat exchanger 5 receives air blown by a blower fan (not shown), evaporates the refrigerant decompressed by the expansion valve 4 by heat exchange with the atmosphere, and the refrigerant that has become a gas is sucked into the refrigerant compressor 2. Is done.

給湯関係の給湯水加熱回路Ｋ１は、給湯用水の加熱手段である上記冷媒水熱交換器３の給湯水通路３ｂと、給湯用水を循環させる給湯水循環ポンプ６と、給湯用水を貯留する貯湯タンク７とを環状に接続して構成される。給湯水循環ポンプ６は、図１に示すように、貯湯タンク７内の下部に設けられた低温水流出入部７ｂから冷水を冷媒水熱交換器３の給湯水通路３ｂを通して貯湯タンク７の上部に設けられた温水流出入部７ｃから還流する様に水流を発生させる。この給湯水循環ポンプ６は、内蔵するモータの回転数に応じて流水量を調節することができ、制御装置３０により通電制御される。   A hot water supply heating circuit K1 related to hot water supply includes a hot water supply passage 3b of the refrigerant water heat exchanger 3 serving as heating means for hot water supply, a hot water circulation pump 6 for circulating hot water, and a hot water storage tank 7 for storing hot water. Are connected in a ring shape. As shown in FIG. 1, the hot water circulating pump 6 is provided with cold water from the low temperature water inflow / outflow portion 7 b provided at the lower part of the hot water tank 7 through the hot water passage 3 b of the refrigerant water heat exchanger 3 and at the upper part of the hot water tank 7. A water flow is generated so as to recirculate from the warm water inflow / outflow portion 7c. The hot water circulation pump 6 can adjust the amount of flowing water according to the number of rotations of a built-in motor, and is energized and controlled by the control device 30.

貯湯タンク７は、耐蝕性に優れた金属製（例えばステンレス製）で断熱構造を有し、高温の給湯用水を長時間にわたって保温することができる。貯湯タンク７に貯留された給湯用水は、出湯時に低温水混合手段である給湯混合弁１３で、貯湯タンク７上部の高温水流出部７ｆからの高温水と水道からの冷水とを混合して温度調節した後、主に台所や風呂などに給湯される。尚、給湯混合弁１３も制御装置３０により通電制御される。   The hot water storage tank 7 is made of metal (for example, made of stainless steel) excellent in corrosion resistance and has a heat insulating structure, and can keep hot hot water for a long time. The hot water supply water stored in the hot water storage tank 7 is mixed with hot water from the high temperature water outflow part 7f above the hot water storage tank 7 and cold water from the water supply by the hot water supply mixing valve 13 which is a low temperature water mixing means when the hot water is discharged. After adjustment, hot water is supplied mainly to kitchens and baths. The hot water mixing valve 13 is also energized and controlled by the control device 30.

次に、床暖房ユニット１ｃであるが、大きく分けてブラインを加熱するブライン加熱回路Ｋ２と、床暖器１０へのブライン循環回路Ｂｊとで構成されている。まず、ブラインを加熱するブライン加熱回路Ｋ２は、ブラインの加熱手段である水ブライン熱交換器８と、熱源水を循環させる給湯用循環ポンプ９と、高温水を貯留する先の貯湯タンク７とを環状に接続して構成される。   Next, although it is the floor heating unit 1c, it is comprised roughly by the brine heating circuit K2 which heats a brine, and the brine circulation circuit Bj to the floor warmer 10. FIG. First, a brine heating circuit K2 for heating brine includes a water brine heat exchanger 8 that is a heating means for brine, a hot water supply circulation pump 9 that circulates heat source water, and a hot water storage tank 7 that stores high-temperature water. It is configured by connecting in a ring.

水ブライン熱交換器８は、貯湯タンク７に貯留された高温水とブラインとを熱交換してブラインを加熱するもので、高温水通路８ａに隣接してブライン通路８ｂが設けられ、その高温水通路８ａを流れる温水の流れ方向とブライン通路８ｂを流れるブラインの流れ方向とが対向するように構成されている。   The water brine heat exchanger 8 heats the brine by exchanging the high temperature water stored in the hot water storage tank 7 and the brine, and a brine passage 8b is provided adjacent to the high temperature water passage 8a. The flow direction of the hot water flowing through the passage 8a and the flow direction of the brine flowing through the brine passage 8b are configured to face each other.

そして、本実施形態の要部として、水ブライン熱交換器８の上流側、特に貯湯タンク７の上部側となる部位（接続部）Ａにて、給湯水加熱回路Ｋ１とブライン加熱回路Ｋ２とを
接続して連通させている。熱源水循環ポンプ９は、図１に示すように、貯湯タンク７内の上部に設けられた先の温水流出入部７ｃから高温水を水ブライン熱交換器８の高温水通路８ａを通して貯湯タンク７の下方部に設けられた中温水流入部７ｅから還流する様に水流を発生させる。この熱源水循環ポンプ９は、内蔵するモータの回転数に応じて流水量を調節することができ、制御装置３０により通電制御される。 And as the principal part of this embodiment, in the site | part (connection part) A which becomes the upper stream side of the water brine heat exchanger 8, especially the upper part of the hot water storage tank 7, the hot water supply heating circuit K1 and the brine heating circuit K2 are provided. Connect and communicate. As shown in FIG. 1, the heat source water circulation pump 9 is arranged below the hot water tank 7 through the hot water passage 8 a of the water brine heat exchanger 8 through the hot water inflow / outflow portion 7 c provided in the upper part of the hot water tank 7. A water flow is generated so as to recirculate from an intermediate temperature water inflow portion 7e provided in the portion. The heat source water circulation pump 9 can adjust the amount of flowing water according to the number of rotations of a built-in motor, and is energized and controlled by the control device 30.

また、床暖器１０へのブライン循環回路Ｂｊは、ブラインの加熱手段である上記水ブライン熱交換器８のブライン通路８ｂと、本実施例では暖房器として床暖房パネル１０と、ブラインを循環させるブライン用循環ポンプ１１とを環状に接続して構成される。床暖房パネル１０は、住居居室の床板下に配置される配管パネルである。   Further, the brine circulation circuit Bj to the floor warmer 10 circulates the brine in the brine passage 8b of the water-brine heat exchanger 8, which is a heating means of the brine, and the floor heating panel 10 as a heater in this embodiment. The brine circulation pump 11 is connected in a ring shape. The floor heating panel 10 is a piping panel arranged below the floor board of a residential room.

また、ブライン用循環ポンプ１１は、内蔵するモータの回転数に応じて循環させるブラインの流量を調節することができる。そして、このような床暖房は、人体が直接床材に触れても快適な暖房感が得られるよう、ブラインを熱く感じない６０℃程度の温度で供給し、冷たく感じない４０℃程度の温度で戻ってくるよう、流量を制御装置３０により通電制御される。   Moreover, the circulation pump 11 for brine can adjust the flow volume of the brine circulated according to the rotation speed of the built-in motor. And such floor heating supplies the brine at a temperature of about 60 ° C. that does not feel hot, and a temperature of about 40 ° C. that does not feel cold so that a comfortable heating feeling can be obtained even if the human body touches the floor material directly. The flow rate is controlled by the control device 30 so as to return.

本貯湯式給湯暖房装置１の作動としては、周知のヒートポンプサイクルと給湯水加熱回路Ｋ１とを用いた貯湯運転と、周知のブライン加熱回路Ｋ２とブライン循環回路Ｂｊとを用いた暖房運転以外に、本実施形態での特徴的な作動として沸き上げ暖房運転がある。これは、状況に応じて給湯水加熱回路Ｋ１で沸き上げた温水を先の接続部Ａを介してブライン加熱回路Ｋ２へ直接循環させて暖房を行うものである。   The operation of the hot water storage hot water heater 1 is not limited to a hot water storage operation using a known heat pump cycle and a hot water heating circuit K1, and a heating operation using a known brine heating circuit K2 and a brine circulation circuit Bj. There is boiling heating operation as a characteristic operation in the present embodiment. According to the situation, the hot water boiled in the hot water supply heating circuit K1 is directly circulated to the brine heating circuit K2 through the previous connection portion A to perform heating.

これは、給湯水加熱回路Ｋ１の給湯水循環ポンプ６とブライン加熱回路Ｋ２の熱源水循環ポンプ９とで流量を略同等とすることにより、給湯水加熱回路Ｋ１で沸き上げた温水が貯湯タンク７をバイパスして、ほぼそのままブライン加熱回路Ｋ２へ流すことができる。これによりヒートポンプ熱源機１ａでは、暖房に適した低い温度で沸き上げを行うことができるため、ＣＯＰが向上する。   This is because the hot water boiled in the hot water heating circuit K1 bypasses the hot water tank 7 by making the flow rates substantially equal between the hot water circulation pump 6 of the hot water heating circuit K1 and the heat source water circulation pump 9 of the brine heating circuit K2. As a result, it can flow almost directly to the brine heating circuit K2. Thereby, in the heat pump heat source machine 1a, since it can boil at the low temperature suitable for heating, COP improves.

図７は、制御装置３０における制御の一例を示すフローチャートである。ステップＳ１で直接暖房沸き上げを行うのか否かを判定し、その判定結果がＹＥＳで直接暖房沸き上げを行う場合はステップＳ２へ進み、ヒートポンプ熱源機１ａでの沸き上げ熱量を暖房必要熱量に変更して運転を行い、ステップＳ１での判定結果がＮＯで直接暖房沸き上げを行わない通常沸き上げの場合はステップＳ３へ進み、ヒートポンプ熱源機１ａでの沸き上げ熱量を通常の定格熱量に変更して運転を行うものである。   FIG. 7 is a flowchart illustrating an example of control in the control device 30. In step S1, it is determined whether or not direct heating and heating are performed. If the determination result is YES and direct heating and heating is performed, the process proceeds to step S2, and the amount of heating in the heat pump heat source unit 1a is changed to the amount of heat required for heating. If the result of determination in step S1 is NO and normal boiling is not performed, the process proceeds to step S3, and the amount of heating in the heat pump heat source unit 1a is changed to the normal rated heat amount. Driving.

ここで、本実施形態での特徴と、その効果についてまとめると、水ブライン熱交換器８よりも上流側において給湯水加熱回路Ｋ１とブライン加熱回路Ｋ２とを接続している。これによれば、貯湯タンク７を介さないで（つまり、貯湯タンク７内の貯湯と関係なく）直接ヒートポンプ熱源機１ａで沸き上げた温水を暖房側へ供給することができるようになり、暖房で必要とする低い温度（４０℃〜６０℃程度）で沸き上げることができるようになることから、ヒートポンプ熱源機１ａのＣＯＰを向上させることができる。   Here, when the characteristics in this embodiment and the effects thereof are summarized, the hot water supply heating circuit K1 and the brine heating circuit K2 are connected upstream of the water brine heat exchanger 8. According to this, it becomes possible to supply hot water boiled directly by the heat pump heat source unit 1a to the heating side without passing through the hot water storage tank 7 (that is, regardless of the hot water storage in the hot water storage tank 7). Since it becomes possible to boil at a required low temperature (about 40 ° C. to 60 ° C.), the COP of the heat pump heat source apparatus 1a can be improved.

また、ヒートポンプ熱源機１ａから貯湯タンク７へ貯湯する場合のヒートポンプ熱源機１ａでの沸き上げ熱量に対し、ヒートポンプ熱源機１ａから直接ブライン加熱回路Ｋ２へ温水を供給する場合のヒートポンプ熱源機１ａでの沸き上げ熱量を低く制御するようにしている。これによれば、給湯および暖房への利用が両方可能な貯湯タンク７内への蓄熱する沸き上げ熱量は高くし、直接ブライン加熱回路Ｋ２へヒートポンプ熱源機１ａからの湯を供給する場合は、暖房に消費される熱量程度に低くすることで、貯湯タンク７内へ無駄な熱量を入れることなく、残湯による二度沸かしによるＣＯＰ低下を防ぐ事ができる。   Moreover, in the heat pump heat source unit 1a when supplying hot water directly from the heat pump heat source unit 1a to the brine heating circuit K2 with respect to the amount of heat generated in the heat pump heat source unit 1a when the hot water is stored in the hot water storage tank 7 from the heat pump heat source unit 1a. The boiling heat amount is controlled to be low. According to this, when the amount of boiling heat to be stored in the hot water storage tank 7 that can be used for both hot water supply and heating is increased, and the hot water from the heat pump heat source unit 1a is directly supplied to the brine heating circuit K2, heating is performed. By reducing the amount of heat consumed to about 10%, it is possible to prevent the COP from being lowered by boiling twice with the remaining hot water without putting unnecessary heat into the hot water storage tank 7.

（第２実施形態）
図２は、本発明の第２実施形態における貯湯式給湯暖房装置の構成を示す模式図である。上述した第１実施形態と異なる特徴は、給湯水加熱回路Ｋ１で沸き上げた温水がブライン加熱回路Ｋ２へと循環する流量を調整する第１の流量調整手段１４を有している。本実施形態では流量調整手段１４として比例弁を用いていずれかの経路と他の２経路との連通割合を可変するとともに、給湯水加熱回路Ｋ１の給湯水循環ポンプ６とブライン加熱回路Ｋ２の熱源水循環ポンプ９との流量をコントロールすることにより、貯湯タンク７の上部へ貯湯しながら暖房を行ったり、貯湯タンク７の上部から高温水を補充しながら暖房を行ったりができるようになっている。 (Second Embodiment)
FIG. 2 is a schematic diagram illustrating a configuration of a hot water storage type hot water supply / room heating apparatus according to a second embodiment of the present invention. A feature different from the first embodiment described above is that there is a first flow rate adjusting means 14 that adjusts the flow rate at which the hot water boiled up in the hot water supply heating circuit K1 circulates to the brine heating circuit K2. In this embodiment, a proportional valve is used as the flow rate adjusting means 14 to change the communication ratio between one of the paths and the other two paths, and the hot water circulation pump 6 of the hot water heating circuit K1 and the heat source water circulation of the brine heating circuit K2. By controlling the flow rate with the pump 9, heating can be performed while storing hot water in the upper part of the hot water storage tank 7, and heating can be performed while replenishing high-temperature water from the upper part of the hot water storage tank 7.

但し、流量調節手段として（１）給湯水加熱回路Ｋ１と温水流出入部７ｃ（２）温水流出入部７ｃとブライン加熱回路Ｋ２（３）給湯水加熱回路Ｋ１とブライン加熱回路Ｋ２との連通をそれぞれ切り換えることのできる切換弁１４を用いても良い。これによれば、ヒートポンプ熱源機１ａから貯湯タンク７へ高温水を貯湯するときに不要なブライン加熱回路Ｋ２側に高温水が流れたり、貯湯タンク７の高温水をブライン加熱回路Ｋ２に流しているときにヒートポンプ熱源機１ａ側から冷水を吸引したりすることを防ぐことができる。   However, as a flow rate adjusting means, (1) hot water supply heating circuit K1 and warm water inflow / outflow part 7c (2) hot water outflow inflow / inflow part 7c and brine heating circuit K2 (3) communication between hot water supply water heating circuit K1 and brine heating circuit K2 are switched. A switching valve 14 that can be used may be used. According to this, when storing high temperature water from the heat pump heat source device 1a to the hot water storage tank 7, high temperature water flows to the side of the brine heating circuit K2, which is unnecessary, or high temperature water from the hot water storage tank 7 is flowing to the brine heating circuit K2. Sometimes, it is possible to prevent cold water from being sucked from the heat pump heat source unit 1a side.

（第３実施形態）
図３は、本発明の第３実施形態における貯湯式給湯暖房装置の構成を示す模式図である。上述の実施形態と異なる特徴は、第１の流量調整手段１４と上流側のヒートポンプ熱源機１ａとの間の給湯水加熱回路Ｋ１と貯湯タンク７の上部とを連通させたバイパス流路１５、もしくは第１の流量調整手段１４と下流側の水ブライン熱交換器８との間のブライン加熱回路Ｋ２と貯湯タンク７の上部とを連通させたバイパス流路１５のいずれかを設けている。尚、図示しないが、流量調節手段１４と下流側の水ブライン熱交換器８との間のブライン加熱回路Ｋ２と貯湯タンク７の上部とを連通させたバイパス流路１５を設けた構成であっても良い。 (Third embodiment)
Drawing 3 is a mimetic diagram showing the composition of the hot water storage type hot-water supply heating device in a 3rd embodiment of the present invention. A feature different from the above-described embodiment is that the hot water supply heating circuit K1 between the first flow rate adjusting means 14 and the upstream heat pump heat source unit 1a communicates with the upper part of the hot water storage tank 7, or One of the bypass flow paths 15 is provided in which the brine heating circuit K2 between the first flow rate adjusting means 14 and the downstream water brine heat exchanger 8 and the upper part of the hot water storage tank 7 communicate with each other. Although not shown in the figure, a bypass flow path 15 is provided in which the brine heating circuit K2 between the flow rate adjusting means 14 and the downstream water brine heat exchanger 8 and the upper part of the hot water storage tank 7 communicate with each other. Also good.

これによれば、給湯水加熱回路Ｋ１とブライン加熱回路Ｋ２とで流量に差を設けても、その流量差をバイパス流路１５で吸収することができる。例えば給湯水加熱回路Ｋ１の流量＞ブライン加熱回路Ｋ２の流量であれば、その流量差分をバイパス流路１５から貯湯タンク７の上部へ貯湯しながら暖房を行うこともでき、給湯水加熱回路Ｋ１の流量＜ブライン加熱回路Ｋ２の流量であればその流量差分、貯湯タンク７の上部からバイパス流路１５を介して高温水を補充しながら暖房を行うこともできるようになる。   According to this, even if there is a difference in flow rate between the hot water heating circuit K1 and the brine heating circuit K2, the flow rate difference can be absorbed by the bypass flow path 15. For example, if the flow rate of the hot water heating circuit K1> the flow rate of the brine heating circuit K2, heating can be performed while hot water is stored from the bypass flow path 15 to the upper part of the hot water storage tank 7, and the hot water heating circuit K1 If the flow rate <the flow rate of the brine heating circuit K2, the difference between the flow rates, heating can be performed while replenishing high temperature water from the upper part of the hot water storage tank 7 via the bypass passage 15.

（第４実施形態）
図４は、本発明の第４実施形態における貯湯式給湯暖房装置の構成を示す模式図である。上述の実施形態と異なる特徴は、給湯水加熱回路Ｋ１とブライン加熱回路Ｋ２とを接続した部位Ａと上流側のヒートポンプ熱源機１ａとの間の給湯水加熱回路Ｋ１から貯湯タンク７の中間部７ｇへ分岐させた分岐流路１６を設けると共に、その分岐部に沸き上げ流路切換手段１７を配設し、制御装置３０は状況に応じて沸き上げ流路切換手段１７を制御するようにしている。 (Fourth embodiment)
FIG. 4 is a schematic diagram showing a configuration of a hot water storage type hot water supply / room heating apparatus according to a fourth embodiment of the present invention. A feature different from the above-described embodiment is that an intermediate portion 7g of the hot water storage tank 7 from the hot water heating circuit K1 between the portion A connecting the hot water heating circuit K1 and the brine heating circuit K2 and the upstream heat pump heat source unit 1a. A branch flow path 16 is provided, and a boiling flow path switching means 17 is provided at the branch portion. The control device 30 controls the boiling flow path switching means 17 according to the situation. .

尚、沸き上げ流路切換手段１７は比例弁であっても切換弁であっても良い。これによれば、ヒートポンプ熱源機１ａが低温で沸き上げているときで暖房での使用温水量が少ない場合など、過剰となった低温沸き上げ温水を中温水として貯湯タンク７の中間部７ｇに溜めることができる。   The boiling flow path switching means 17 may be a proportional valve or a switching valve. According to this, when the heat pump heat source unit 1a is boiling at a low temperature and the amount of hot water used for heating is small, excess low-temperature boiling hot water is stored in the intermediate portion 7g of the hot water storage tank 7 as intermediate temperature water. be able to.

（第５実施形態）
図５は、本発明の第５実施形態における貯湯式給湯暖房装置の構成を示す模式図である。上述の実施形態と異なる特徴は、中温水取り出し経路１８と、その中温水取り出し経路１８から取り出した中温水と貯湯タンク７の上部から取り出した高温水とを混合して給湯設定温度よりも所定温度以上高い温度に調節する中温水混合手段としての中温水混合弁１２とを有し、その中温水混合弁１２から流出する温水と給水路から供給される低温水とを低温水混合手段としての給湯混合弁１３にて混合して給湯設定温度に調節する貯湯式給湯暖房装置において、先の分岐流路１６を中温水取り出し経路１８に接続している。 (Fifth embodiment)
FIG. 5 is a schematic diagram showing a configuration of a hot water storage type hot water supply / room heating device according to a fifth embodiment of the present invention. A feature different from the above-described embodiment is that the medium-temperature water take-out path 18, the medium-temperature water taken out from the medium-temperature water take-out path 18 and high-temperature water taken out from the upper part of the hot water storage tank 7 are mixed to have a predetermined temperature higher than the preset hot water supply temperature. The hot water supply valve as the low temperature water mixing means includes the intermediate temperature water mixing valve 12 as the intermediate temperature water mixing means for adjusting the temperature to a high temperature, and the hot water flowing out from the intermediate temperature water mixing valve 12 and the low temperature water supplied from the water supply channel. In the hot water storage type hot water supply and heating apparatus that is mixed by the mixing valve 13 and adjusted to the hot water supply set temperature, the previous branch flow path 16 is connected to the intermediate hot water take-out path 18.

これは、周知の中温水取り出しがあるものにおいてはその中温水取り出し経路１８を用いて中温水の注入も行うようにするものである。配管経路を兼用した構成となるため貯湯タンク７の接続孔を増やすこともなく、簡易でコストを抑えることができる。また、貯湯タンク７の放熱ロスも抑えることができる。   In this case, in the case where there is a known medium-temperature water extraction, the intermediate-temperature water is also injected using the medium-temperature water extraction path 18. Since it becomes the structure which shared the piping path, it does not increase the connection hole of the hot water storage tank 7, and can suppress cost simply. Moreover, the heat loss of the hot water storage tank 7 can also be suppressed.

FIG. 6 is a schematic diagram illustrating a configuration of a hot water storage type hot water supply / room heating device according to a sixth embodiment of the present invention. A feature different from the above-described embodiment is that the branched flow branched from the hot water heating circuit K1 between the heat pump heat source unit 1a on the upstream side of the portion A where the hot water heating circuit K1 and the brine heating circuit K2 are connected. The passage 16 and the second flow rate adjusting means 19 for adjusting the flow rate of the hot water flowing into the branch flow channel 16 and the flow rate of the hot water flowing toward the portion A side are provided. The second flow rate adjusting means 19 may be a proportional valve or a switching valve. According to this, the amount of hot water turned to heating by the second flow rate adjusting means 19 and the amount of hot water injected into the hot water storage tank 7 can be adjusted.

また、分岐流路１６と貯湯タンク７の中間部７ｇとを接続する第１流路３１と、分岐流路１６と貯湯タンク７の下方部７ｉとを接続する第２流路３２とを有し、第２の流量調整手段１９は、分岐流路１６から第１流路３１へと流入する温水の流量および分岐流路１６から第２の流路３１へと流入する温水の流量を調整するようにしている。これによれば、貯湯タンク７内の残湯状況に応じて、中温水の注入位置を変えることができる。   Moreover, it has the 1st flow path 31 which connects the branch flow path 16 and the intermediate part 7g of the hot water storage tank 7, and the 2nd flow path 32 which connects the branch flow path 16 and the lower part 7i of the hot water storage tank 7.

（第７実施形態）
図７は、本発明の第７実施形態における貯湯式給湯暖房装置の構成を示す模式図である。上述の実施形態と異なる特徴は、貯湯タンク７の下部側にて給湯水加熱回路Ｋ１とブライン加熱回路Ｋ２とを接続して連通させたバイパス流路２０を設けると共に、制御装置３０は、状況に応じてブライン加熱回路Ｋ２で熱交換を終えた温水をバイパス流路２０を介して給湯水加熱回路Ｋ１へ循環させるようにしている。これによれば、貯湯タンク７内に不要な中温水を注入することが防げるため、残湯を増やしたり２度沸かししたりすることによるＣＯＰの悪化を防ぐことができる。 (Seventh embodiment)
FIG. 7 is a schematic diagram illustrating a configuration of a hot water storage type hot water supply / room heating device according to a seventh embodiment of the present invention. A feature different from the above-described embodiment is that a bypass channel 20 is provided on the lower side of the hot water storage tank 7 to connect the hot water heating circuit K1 and the brine heating circuit K2 and communicate with each other. Accordingly, the hot water having been subjected to heat exchange in the brine heating circuit K2 is circulated to the hot water supply water heating circuit K1 via the bypass flow path 20. According to this, since it is possible to prevent unnecessary medium temperature water from being poured into the hot water storage tank 7, it is possible to prevent the deterioration of COP caused by increasing the remaining hot water or boiling it twice.

また、ブライン加熱回路Ｋ２から給湯水加熱回路Ｋ１へ温水を供給する場合のヒートポンプ熱源機１ａでの沸き上げ熱量は、貯湯タンク７へ蓄熱する場合のヒートポンプ熱源機１ａでの沸き上げ熱量よりも低く制御するようにしている。作動としては第１実施形態での図７のフローチャートと同様になる。これによれば、暖房で消費される熱量以上の熱量を貯湯タンク７へ蓄熱することが少なくなるため、残湯によるＣＯＰ低下を防ぐことができる。   In addition, when the hot water is supplied from the brine heating circuit K2 to the hot water supply heating circuit K1, the amount of heating in the heat pump heat source unit 1a is lower than the amount of heating in the heat pump heat source unit 1a when storing heat in the hot water storage tank 7. I try to control it. The operation is the same as the flowchart of FIG. 7 in the first embodiment. According to this, since the amount of heat more than the amount of heat consumed by heating is less likely to be stored in the hot water storage tank 7, it is possible to prevent a COP decrease due to the remaining hot water.

（第８実施形態）
図９は、本発明の第８実施形態における貯湯式給湯暖房装置の構成を示す模式図である。上述の実施形態と異なる特徴は、先のバイパス流路２０のいずれか一端側、もしくは両端の接続部に流量調節手段２１を配設すると共に、制御装置３０は状況に応じて流量調節手段２１を制御するようにしている。尚、この流量調節手段２１は比例弁であっても切換弁であっても良い。これによれば、貯湯タンク７の下部に不要な中温水が流入したり、貯湯タンク７の下部から不要に冷水を吸引したりすることを防ぐことができる。 (Eighth embodiment)
FIG. 9 is a schematic diagram showing a configuration of a hot water storage type hot water supply / room heating device according to an eighth embodiment of the present invention. A feature different from the above-described embodiment is that the flow rate adjusting means 21 is disposed on one end side or both ends of the bypass flow path 20, and the control device 30 sets the flow rate adjusting means 21 according to the situation. I try to control it. The flow rate adjusting means 21 may be a proportional valve or a switching valve. According to this, it is possible to prevent unnecessary middle temperature water from flowing into the lower part of the hot water storage tank 7 and unnecessary suction of cold water from the lower part of the hot water storage tank 7.

本実施形態では流量調節手段として、いずれかの経路と他の２経路との連通割合を可変できる比例弁２１を用いると共に、給湯水加熱回路Ｋ１の給湯水循環ポンプ６とブライン加熱回路Ｋ２の熱源水循環ポンプ９との流量をコントロールすることにより、中温水をヒートポンプ熱源機１ａへ供給しながら、貯湯タンク７の下部へ中温水を戻したり、貯湯タンク７の下部から冷水を流出させたりができるようになっている。   In this embodiment, a proportional valve 21 that can change the communication ratio between one of the two paths and the other two paths is used as the flow rate adjusting means, and the hot water circulation pump 6 of the hot water heating circuit K1 and the heat source water circulation of the brine heating circuit K2 are used. By controlling the flow rate with the pump 9, the medium temperature water can be returned to the lower part of the hot water storage tank 7 and the cold water can be discharged from the lower part of the hot water storage tank 7 while supplying the intermediate temperature water to the heat pump heat source unit 1 a. It has become.

但し、流量調節手段として1)ブライン加熱回路Ｋ２と低温水流出入部７ｂ2)低温水流出入部７ｂと給湯水加熱回路Ｋ１3)ブライン加熱回路Ｋ２と給湯水加熱回路Ｋ１との連通をそれぞれ切り換えることのできる切換弁２１を用いても良い。これによれば、構成が簡素になることよりコストを抑えることができる。   However, as the flow rate adjusting means, 1) the brine heating circuit K2 and the low temperature water inflow / outflow portion 7b2) the low temperature water outflow inflow portion 7b and the hot water heating circuit K13), the communication between the brine heating circuit K2 and the hot water heating circuit K1 can be switched respectively.
