Description

本発明は、吸収式加熱装置に圧縮式加熱装置を組合せたハイブリッド吸収式ヒートポンプシステム、吸収式冷却装置に圧縮式冷却装置を組合せたハイブリッド吸収式ヒートポンプシステム、ならびに吸収式加熱・冷却装置に圧縮式加熱・冷却装置を組合せたハイブリッド吸収式ヒートポンプシステムに関する。 The present invention relates to a hybrid absorption heat pump system in which a compression heating device is combined with an absorption heating device, a hybrid absorption heat pump system in which a compression cooling device is combined with an absorption cooling device, and a compression type in an absorption heating / cooling device. The present invention relates to a hybrid absorption heat pump system combined with a heating / cooling device.

従来から、吸収式加熱装置を利用して給湯と暖房を行なう吸収式ヒートポンプシステムや、吸収式冷却装置を利用して給湯と冷房を行なう吸収式ヒートポンプシステムが知られている。あるいは、吸収式冷却・加熱装置を利用して給湯と冷暖房を行なう吸収式ヒートポンプシステムが知られている（例えば特許文献１）。本明細書では、冷却・加熱装置とは、切換えることによって加熱された液を供給したり冷却された液を供給したりする装置を言う。構成上は冷却・加熱装置であっても、専ら加熱された液を供給する用い方がされる装置を加熱装置ということがあり、専ら冷却された液を供給する用い方がされる装置を冷却装置ということがある。ただし、加熱装置には冷却運転できないものも含まれ、冷却装置には加熱運転できないものも含まれる。
吸収式冷却・加熱装置は、冷媒で希釈された吸収溶液を加熱して冷媒蒸気と濃縮吸収溶液に分離する再生器と、分離された冷媒蒸気を凝縮する冷媒凝縮器と、凝縮された冷媒を蒸発させる冷媒蒸発器と、蒸発した冷媒を濃縮吸収溶液に吸収させる冷媒吸収器を備えている。冷媒は、冷媒蒸発器で蒸発し、冷媒吸収器で濃縮吸収溶液に吸収され、再生器で吸収溶液から蒸発して分離され、冷媒凝縮器で凝縮されるサイクルを繰返す。吸収溶液は、冷媒吸収器で冷媒を吸収して希釈化され、再生器で冷媒が蒸発して濃縮されるサイクルを繰返す。
冷媒吸収器で冷媒蒸気を濃縮吸収溶液に吸収するときに発熱することから、液を冷媒吸収器に通過させると液は加熱される。液を冷媒凝縮器に通過させると、液は冷媒蒸気を冷却して冷媒を凝縮させるとともに液自体は加熱される。加熱された液を利用すると暖房装置で暖房することや、給湯装置で給湯することが可能となる。
冷媒蒸発器で蒸発するときに冷却されることから、液を冷媒蒸発器に通過させると液は冷却される。冷却された液を利用すると冷房装置で冷房することが可能となる。
吸収式冷却・加熱装置は、冷媒吸収器と冷媒凝縮器を通過する液を利用すると、吸収式加熱装置となり、加熱された液を利用して暖房装置で暖房することを可能とする。冷媒蒸発器を通過する液を利用すると、吸収式冷却装置となり、冷却された液を利用して冷房装置で冷房することを可能とする。
給湯装置は、冷媒吸収器と冷媒凝縮器で発生する熱を利用して水道水を加熱して給湯する。 Conventionally, an absorption heat pump system that performs hot water supply and heating using an absorption heating device and an absorption heat pump system that performs hot water supply and cooling using an absorption cooling device are known. Alternatively, an absorption heat pump system that performs hot water supply and cooling / heating using an absorption cooling / heating device is known (for example, Patent Document 1). In this specification, the cooling / heating apparatus refers to an apparatus that supplies a heated liquid or a cooled liquid by switching. Even if it is a cooling / heating device, the device that is used exclusively to supply the heated liquid is sometimes referred to as the heating device, and the device that is used exclusively to supply the cooled liquid is cooled. Sometimes called a device. However, the heating device includes those that cannot be cooled, and the cooling device includes those that cannot be heated.
The absorption cooling / heating device heats an absorbing solution diluted with a refrigerant to separate it into a refrigerant vapor and a concentrated absorption solution, a refrigerant condenser that condenses the separated refrigerant vapor, and a condensed refrigerant. A refrigerant evaporator for evaporating and a refrigerant absorber for absorbing the evaporated refrigerant into the concentrated absorbent solution are provided. The refrigerant evaporates in the refrigerant evaporator, is absorbed in the concentrated absorbent solution by the refrigerant absorber, is evaporated and separated from the absorbent solution by the regenerator, and is condensed in the refrigerant condenser. The absorbing solution is diluted by absorbing the refrigerant in the refrigerant absorber and evaporating and concentrating the refrigerant in the regenerator.
Since heat is generated when the refrigerant vapor is absorbed into the concentrated absorbent solution by the refrigerant absorber, the liquid is heated when the liquid is passed through the refrigerant absorber. When the liquid is passed through the refrigerant condenser, the liquid cools the refrigerant vapor to condense the refrigerant and the liquid itself is heated. When the heated liquid is used, it is possible to heat with a heating device or to supply hot water with a hot water supply device.
Since it is cooled when it evaporates in the refrigerant evaporator, the liquid is cooled when it passes through the refrigerant evaporator. When the cooled liquid is used, it becomes possible to cool with the cooling device.
When the liquid that passes through the refrigerant absorber and the refrigerant condenser is used, the absorption-type cooling / heating apparatus becomes an absorption-type heating apparatus, and it is possible to heat the heated liquid using the heating liquid. When the liquid passing through the refrigerant evaporator is used, an absorption cooling device is formed, and the cooled liquid can be used to cool the cooling device.
The hot water supply device supplies hot water by heating tap water using heat generated by the refrigerant absorber and the refrigerant condenser.

吸収式暖房装置の運転を持続するためには、あるいは吸収式冷却・加熱装置の加熱運転を持続するためには、冷媒蒸発器を通過する液が過度に冷却されないように加熱する必要がある。通常は、冷媒蒸発器で冷却された液を大気で加熱する。
吸収式冷却装置の運転を持続するためには、あるいは吸収式冷却・加熱装置の冷却運転を持続するためには、冷媒吸収器と冷媒凝縮器を通過する液が過熱されないように冷却する必要がある。通常は、冷媒吸収器と冷媒凝縮器で加熱された液を大気で冷却する。 In order to continue the operation of the absorption heating device, or in order to continue the heating operation of the absorption cooling / heating device, it is necessary to heat the liquid that passes through the refrigerant evaporator so as not to be excessively cooled. Usually, the liquid cooled by the refrigerant evaporator is heated in the atmosphere.
In order to continue the operation of the absorption cooling device or the cooling operation of the absorption cooling / heating device, it is necessary to cool the liquid passing through the refrigerant absorber and the refrigerant condenser so as not to be overheated. is there. Usually, the liquid heated by the refrigerant absorber and the refrigerant condenser is cooled in the atmosphere.

前記したように、暖房運転ないしは加熱運転を持続するとともに、十分な温度で給湯するには、冷媒蒸発器で冷却された液を加熱する必要がある。暖房運転が必要とされるのは大気温度が低いときであるが、特に大気温度が低い場合（例えば、５℃以下）に大気で加熱しようとしても、加熱に必要とされるだけの熱を得られない。この結果、暖房運転が不能となってしまうのみならず、給湯も不能となってしまう虞がある。一方、冷房運転ないしは冷却運転を持続するためには、冷媒吸収器と冷媒凝縮器で加熱された液を冷却する必要がある。冷房運転が必要とされるのは大気温度が高い場合であるが、特に大気温度が高い場合（例えば、３５℃以上）に大気で冷却しようとしても、必要とされるだけの冷却ができない。
このように暖房運転や給湯が不能となってしまったり、冷房運転が不能となってしまうと、システムに求められる能力を欠いていることとなり、不完全なシステムとなってしまう。 As described above, in order to maintain the heating operation or the heating operation and to supply hot water at a sufficient temperature, it is necessary to heat the liquid cooled by the refrigerant evaporator. Heating operation is required when the atmospheric temperature is low, but especially when the atmospheric temperature is low (for example, 5 ° C or less), even when trying to heat in the atmosphere, the heat necessary for heating is obtained. I can't. As a result, there is a possibility that not only heating operation becomes impossible but also hot water supply becomes impossible. On the other hand, in order to continue the cooling operation or the cooling operation, it is necessary to cool the liquid heated by the refrigerant absorber and the refrigerant condenser. The cooling operation is required when the atmospheric temperature is high. However, when the atmospheric temperature is particularly high (for example, 35 ° C. or more), even if it is attempted to cool in the atmosphere, the required cooling cannot be performed.
When heating operation or hot water supply becomes impossible or cooling operation becomes impossible in this way, the capability required of the system is lacking, resulting in an incomplete system.

冷却された第２循環液を加熱する方式には、大気熱交換器等を利用して大気で加熱する方式がある。この方式では大気温度が特に低いとき（例えば、５℃以下）は、大気から必要とされるだけの熱を得られず、暖房運転や給湯運転が不能となってしまう虞がある。また、小型のシステムには小型の大気熱交換器しか備えられないため、冷却された第２循環液を大気で加熱しても、大気温度が低いとき（例えば、１０℃以下）は、加熱能力が不足して必要なだけの暖房や給湯ができない場合がある。これらの場合は、冷却された第２循環液を熱媒体凝縮器で得られる高温でさらに加熱することが好ましい。
本システムによれば、吸収式加熱装置に圧縮式加熱装置を組合せるという簡易な構成によって、手間がかからず、しかも小型の大気熱交換器を備えるだけで、冷却された第２循環液を効率良く必要な温度まで加熱することができる。 (One preferred means)
During the heating operation, the hybrid absorption heat pump system heats the second circulating liquid cooled by the refrigerant evaporator in the atmosphere, and further heats the second circulating liquid heated in the atmosphere at a high temperature obtained by the heat medium condenser. It is preferable to do.
(The action and effect)
As a method of heating the cooled second circulating liquid, there is a method of heating in the atmosphere using an atmospheric heat exchanger or the like. In this method, when the atmospheric temperature is particularly low (for example, 5 ° C. or less), heat necessary for the atmosphere cannot be obtained, and there is a possibility that the heating operation or the hot water supply operation becomes impossible. In addition, since a small system is equipped only with a small atmospheric heat exchanger, even if the cooled second circulating fluid is heated in the atmosphere, when the atmospheric temperature is low (for example, 10 ° C. or less), the heating capacity Insufficient heat and hot water supply may not be possible. In these cases, it is preferable to further heat the cooled second circulating liquid at a high temperature obtained by the heat medium condenser.
According to the present system, the simple configuration of combining the absorption heating device with the compression heating device does not require time and effort, and the second circulating liquid that has been cooled can be obtained only by providing a small atmospheric heat exchanger. It can be efficiently heated to the required temperature.

（一つの好ましい手段）
ハイブリッド吸収式ヒートポンプシステムは、冷房運転時には、前記冷媒吸収器と前記冷媒凝縮器を循環する第２循環液を大気で冷却し、大気で冷却された第２循環液を熱媒体蒸発器で得られる低温でさらに冷却することが好ましい。
（その作用と効果）
加熱された第２循環液を冷却する方式には、クーリングタワー等の蒸発潜熱を利用して冷却する開放方式と大気熱交換器等を利用して大気と顕熱熱交換で冷却する密閉方式がある。クーリングタワーでは水が次第に蒸発することによって、水に溶けた溶質が析出してしまう。析出した溶質の除去のために、クーリングタワーの維持、管理等のメンテナンスに手間がかかってしまうため、家庭用等の小型のシステムでは負担が大きく、実用性が低い。したがって、家庭用等の小型のシステムでは、大気熱交換器等を利用した密閉式で冷却することが好ましい。
しかしながら、小型のシステムには小型の大気熱交換器しか備えられない。よって、大気熱交換器によって大気で第２循環液を冷却しても、大気温度が高いときは、冷却能力が不足して必要なだけの冷房を行うことができない場合がある。また、大気温度が特に高いとき（例えば、３５℃以上）は、必要なだけの冷却ができず、冷房運転が不能となってしまう虞がある。これらの場合は、第２循環液を熱媒体蒸発器で得られる低温でさらに冷却することが好ましい。
本システムによれば、吸収式冷却装置に圧縮式冷却装置を組合せるという簡易な構成によって、手間がかからず、しかも小型の大気熱交換器を備えるだけで、第２循環液を必要な温度まで効率良く冷却することができる。 (One preferred means)
Hybrid absorption heat pump system, in the cooling operation, obtain a second circulating fluid to circulate said refrigerant condenser and the refrigerant absorber was cooled in the atmosphere, the second circulating fluid cooled in the air at the heat medium evaporator It is preferable to further cool at a low temperature.
(The action and effect)
There are two methods for cooling the heated second circulating fluid: an open method that uses latent heat of vaporization such as a cooling tower, and a sealed method that uses sensible heat exchange with the atmosphere using an atmospheric heat exchanger or the like. . In the cooling tower, water gradually evaporates, so that a solute dissolved in water is deposited. Since it takes time to maintain and manage the cooling tower in order to remove the precipitated solutes, a small system for home use has a large burden and is not practical. Therefore, in a small system for home use or the like, it is preferable to cool in a hermetic manner using an atmospheric heat exchanger or the like.
However, a small system can only be equipped with a small atmospheric heat exchanger. Therefore, even if the second circulating liquid is cooled in the atmosphere by the atmospheric heat exchanger, if the atmospheric temperature is high, the cooling capacity may be insufficient and the necessary cooling may not be performed. Further, when the atmospheric temperature is particularly high (for example, 35 ° C. or higher), it is not possible to perform cooling as much as necessary, and there is a possibility that the cooling operation may be disabled. In these cases, it is preferable to further cool the second circulating liquid at a low temperature obtained by the heat medium evaporator.
According to this system, the simple configuration of combining the absorption cooling device with the compression cooling device is labor-saving, and the second circulating fluid is supplied to the required temperature only by providing a small atmospheric heat exchanger. Can be efficiently cooled.

上述したハイブリッド吸収式ヒートポンプシステムは、冷媒で希釈された吸収溶液を加熱して冷媒蒸気と中濃度の吸収溶液に分離する高温再生器と、高温再生機で分離された冷媒蒸気の熱によって中濃度の吸収溶液を再加熱して冷媒蒸気と濃縮吸収溶液に分離する低温再生器を備えている。
（その作用と効果）
いわゆる二重効用の吸収式冷却装置や加熱装置等を利用することによって、吸収溶液を加熱する加熱源の加熱量が少なくすむ。このため、少ない加熱量で効率良く冷房または暖房を行なうことができる。 The above-described hybrid absorption heat pump system includes a high-temperature regenerator that heats an absorption solution diluted with a refrigerant and separates it into a refrigerant vapor and a medium-concentration absorption solution, and a medium concentration by the heat of the refrigerant vapor separated by the high-temperature regenerator. A low-temperature regenerator is provided that reheats the absorbent solution to separate the refrigerant vapor and the concentrated absorbent solution.
(The action and effect)
By using a so-called double-effect absorption cooling device or heating device, the heating amount of the heating source for heating the absorbing solution can be reduced. For this reason, it is possible to efficiently perform cooling or heating with a small heating amount.

本発明を具現化したハイブリッド吸収式ヒートポンプシステムの実施例を、図面を参照しながら詳細に説明する。図１は、本実施例のハイブリッド吸収式ヒートポンプシステム１の暖房運転時の状態を示し、図２は、冷房運転時の状態を示す。
最初に、暖房運転について説明をする。図１に示すように、ハイブリッド吸収式ヒートポンプシステム１は、空調装置１６と、貯湯熱交換器１８ａと、吸収式冷却・加熱装置２と、圧縮式冷却・加熱装置３から構成されている。 An embodiment of a hybrid absorption heat pump system embodying the present invention will be described in detail with reference to the drawings. FIG. 1 shows a state during heating operation of the hybrid absorption heat pump system 1 of the present embodiment, and FIG. 2 shows a state during cooling operation.
First, the heating operation will be described. As shown in FIG. 1, the hybrid absorption heat pump system 1 includes an air conditioner 16, a hot water storage heat exchanger 18 a, an absorption cooling / heating device 2, and a compression cooling / heating device 3.

吸収式冷却・加熱装置２は、主に、高温再生器４と、低温再生器６と、冷媒凝縮器８と、冷媒蒸発器１２と、冷媒吸収器１４と、大気・液熱交換器２０から構成されている。吸収式冷却・加熱装置２は、水分吸収剤である臭化リチウムの水溶液等のリチウム塩溶液（以下、吸収溶液という）を作動媒体とする。 The absorption cooling / heating device 2 mainly includes a high-temperature regenerator 4, a low-temperature regenerator 6, a refrigerant condenser 8, a refrigerant evaporator 12, a refrigerant absorber 14, and an air / liquid heat exchanger 20. It is configured. The absorption cooling / heating device 2 uses a lithium salt solution (hereinafter referred to as an absorption solution) such as an aqueous solution of lithium bromide that is a moisture absorbent as a working medium.

高温再生器４は、吸収溶液タンク４ａと、加熱源４ｂとを備えている。吸収溶液タンク４ａには、希釈された吸収溶液（以下、希液という）が収容される。吸収溶液タンク４ａに収容された希液は、加熱源４ｂによって加熱されて沸騰し、上部の分離器５で水蒸気と濃縮した中濃度の吸収溶液とに分離される（以下、吸収溶液から発生する水蒸気および水蒸気が凝縮した水を冷媒ということがある。また、中濃度の吸収溶液を中液という）。 The high temperature regenerator 4 includes an absorption solution tank 4a and a heating source 4b. The absorption solution tank 4a stores a diluted absorption solution (hereinafter referred to as a dilute solution). The dilute liquid stored in the absorption solution tank 4a is heated and boiled by the heating source 4b and separated into water vapor and concentrated medium concentration absorption solution by the upper separator 5 (hereinafter, generated from the absorption solution). Water vapor and water condensed with water vapor are sometimes referred to as refrigerants, and medium concentration absorbing solutions are referred to as medium liquids).

分離器５で分離された水蒸気は、冷媒経路５２を経て、低温再生器６内の再生熱交換器６ａ内に供給される。一方、分離器５で分離された中液は、中液経路６２を経て、再生熱交換器６ａの上部から滴下され、低温再生器６内に供給される。低温再生器６内では水蒸気と中液との熱交換が行なわれ、水蒸気は凝縮して水となる。また、低温再生器６内は低圧に保たれているため、この際に生じる凝縮熱によって中液が再沸騰し、中液が水蒸気と高濃度の吸収溶液（以下、濃液という）とに分離される。 The water vapor separated by the separator 5 is supplied into the regenerative heat exchanger 6 a in the low temperature regenerator 6 through the refrigerant path 52. On the other hand, the intermediate liquid separated by the separator 5 is dropped from the upper part of the regenerative heat exchanger 6 a through the intermediate liquid path 62 and supplied into the low temperature regenerator 6. In the low-temperature regenerator 6, heat exchange between the water vapor and the intermediate liquid is performed, and the water vapor is condensed into water. Further, since the low temperature regenerator 6 is kept at a low pressure, the middle liquid is reboiled by the condensation heat generated at this time, and the middle liquid is separated into water vapor and a high concentration absorbing solution (hereinafter referred to as a concentrated liquid). Is done.

再生熱交換器６ａ内で凝縮した水は、低圧に保たれた冷媒凝縮器８内に導かれて一気に蒸発する。また、低温再生器６で中液から分離した水蒸気は、水蒸気通路７を通って冷媒凝縮器８内に移動する。これらの水蒸気は、内部に大気熱交換用循環液が流れる凝縮熱交換器８ａ表面に接触し、凝縮して水となる。冷媒凝縮器８内の下部に溜まった水は、冷媒経路５４を経て、負圧タンク１０内の蒸発熱交換器１２ａの上部から滴下されて冷媒蒸発器１２に供給される。
一方、低温再生器６内で中液から分離され低温再生器６内の下部に溜まった濃液は、濃液経路６４を経て、負圧タンク１０内の吸収熱交換器１４ａの上部から滴下されて冷媒吸収器１４に供給される。 The water condensed in the regenerative heat exchanger 6a is led into the refrigerant condenser 8 kept at a low pressure and evaporated at a stroke. Further, the water vapor separated from the medium liquid by the low temperature regenerator 6 moves into the refrigerant condenser 8 through the water vapor passage 7. These water vapors contact the surface of the condensation heat exchanger 8a through which the circulating fluid for atmospheric heat exchange flows, and are condensed to become water. Water accumulated in the lower part of the refrigerant condenser 8 is dropped from the upper part of the evaporation heat exchanger 12a in the negative pressure tank 10 via the refrigerant path 54 and supplied to the refrigerant evaporator 12.
On the other hand, the concentrated liquid separated from the intermediate liquid in the low temperature regenerator 6 and accumulated in the lower part of the low temperature regenerator 6 is dropped from the upper part of the absorption heat exchanger 14a in the negative pressure tank 10 through the concentrated liquid path 64. To the refrigerant absorber 14.

負圧タンク１０内は低圧に保たれており、冷媒蒸発器１２の蒸発熱交換器１２ａに滴下された水は、蒸発熱交換器１２ａの表面で蒸発する。この際に生じる気化熱は、蒸発熱交換器１２ａ内を流れる大気熱交換用循環液を冷却する。蒸発した水は、冷媒吸収器１４の吸収熱交換器１４ａの表面を流れる濃液に吸収される。この際に生じる吸収熱は、吸収熱交換器１４ａ内を流れる暖房用循環液に吸収されて除去される。
吸収熱交換器１４ａの表面を伝って下流する濃液は、蒸発熱交換器１２ａの表面で発生した水蒸気を吸収するにつれて濃度が低下し、希液となって負圧タンク１０内の下部に溜まる。また、濃液が連続的に水蒸気を吸収することによって、負圧タンク１０内の圧力は一定に保たれる。 The inside of the negative pressure tank 10 is kept at a low pressure, and the water dropped on the evaporation heat exchanger 12a of the refrigerant evaporator 12 evaporates on the surface of the evaporation heat exchanger 12a. The heat of vaporization generated at this time cools the circulating fluid for atmospheric heat exchange flowing in the evaporating heat exchanger 12a. The evaporated water is absorbed by the concentrated liquid flowing on the surface of the absorption heat exchanger 14a of the refrigerant absorber 14. The absorbed heat generated at this time is absorbed and removed by the heating circulating fluid flowing in the absorption heat exchanger 14a.
The concentrated liquid downstream along the surface of the absorption heat exchanger 14a decreases in concentration as it absorbs water vapor generated on the surface of the evaporation heat exchanger 12a, and becomes a dilute liquid and accumulates in the lower part of the negative pressure tank 10. . Further, the concentrated liquid continuously absorbs the water vapor, so that the pressure in the negative pressure tank 10 is kept constant.

負圧タンク１０内の下部に溜まった希液は、ポンプ９７によって希液経路６６を前進する。希液は、希液経路６６を前進するうちに、低温熱交換器２４内で濃液経路６４内を流れる濃液と熱交換して熱を吸収する。これにより濃液は、冷媒吸収器１４内で水蒸気を十分に吸収することができる温度まで下げられる。次に、高温熱交換器２６内で中液経路６２内を流れる中液と熱交換して熱を吸収する。これにより中液は、低温再生器６に供給される前に温度が下げられる。熱を吸収した希液は、高温再生器４の吸収溶液タンク４ａ内に戻される。 The dilute liquid accumulated in the lower part of the negative pressure tank 10 is advanced in the dilute liquid path 66 by the pump 97. As the dilute liquid advances in the dilute liquid path 66, the dilute liquid exchanges heat with the concentrated liquid flowing in the concentrated liquid path 64 in the low-temperature heat exchanger 24 to absorb heat. Thereby, the concentrated liquid is lowered to a temperature at which the water vapor can be sufficiently absorbed in the refrigerant absorber 14. Next, heat is absorbed by exchanging heat with the intermediate liquid flowing in the intermediate liquid path 62 in the high-temperature heat exchanger 26. As a result, the temperature of the medium solution is lowered before being supplied to the low temperature regenerator 6. The diluted liquid that has absorbed heat is returned to the absorbing solution tank 4a of the high-temperature regenerator 4.

暖房運転時には、冷媒吸収器１４の吸収熱交換器１４ａ内に暖房用循環液が流れる。冷媒吸収器１４の吸収熱交換器１４ａで吸収熱を吸収した暖房用循環液は、経路７４を経て冷媒凝縮器８の凝縮熱交換器８ａ内に供給される。凝縮熱交換器８ａでさらに凝縮熱を吸収した暖房用循環液は、凝縮熱交換器８ａから経路７２へ導出される。 During the heating operation, the circulating fluid for heating flows in the absorption heat exchanger 14a of the refrigerant absorber 14. The heating circulating fluid that has absorbed the heat absorbed by the absorption heat exchanger 14 a of the refrigerant absorber 14 is supplied into the condensation heat exchanger 8 a of the refrigerant condenser 8 via the path 74. The heating circulating fluid that has further absorbed the heat of condensation in the condensing heat exchanger 8a is led out to the path 72 from the condensing heat exchanger 8a.

冷媒凝縮器８の凝縮熱交換器８ａから導出された暖房用循環液は、経路７２と発電機２８を通過する。発電機２８は、燃料電池でもよく、エンジン式発電機でもよい。発電機２８は、発電に伴って発電熱を発生する。経路７２を通過する暖房用循環液は、発電熱によってさらに加熱される。発電機２８から排出される高温の排出ガスは、経路７９を経て高温再生器１４に導かれ、希液を加熱する。
暖房運転時には、三方弁９４の第１，第２，第３ポートが全て開かれる。発電機２８を経た暖房用循環液は、三方弁９４で分岐する。第３ポートＣから第１ポートＡを進んだ暖房用循環液は、経路７１から四方弁９０へ導かれる。暖房用循環液は四方弁９０の第４ポートＤから第１ポートＡを通り、経路８０を経て、空調装置１６に供給される。空調装置１６はこの実施例においては温水式である。
空調装置１６で暖房を行なって熱を放出した暖房用循環液は、経路８５を経て四方弁９２の第３ポートＣから第４ポートＤを通って、ポンプ９５によって経路７６を前進し、吸収熱交換器１４ａに戻される。 The heating circulating liquid derived from the condensation heat exchanger 8 a of the refrigerant condenser 8 passes through the path 72 and the generator 28. The generator 28 may be a fuel cell or an engine generator. The generator 28 generates generated heat as power is generated. The heating circulating fluid that passes through the path 72 is further heated by the generated heat. The high-temperature exhaust gas discharged from the generator 28 is guided to the high-temperature regenerator 14 through the path 79, and heats the diluted liquid.
During the heating operation, all of the first, second and third ports of the three-way valve 94 are opened. The circulating fluid for heating that has passed through the generator 28 is branched by a three-way valve 94. The circulating fluid for heating that has advanced from the third port C to the first port A is guided to the four-way valve 90 from the path 71. The circulating fluid for heating passes through the first port A from the fourth port D of the four-way valve 90, and is supplied to the air conditioner 16 through the path 80. The air conditioner 16 is a hot water type in this embodiment.
The heating circulating fluid that has been heated by the air conditioner 16 and has released heat passes through the path 85 from the third port C to the fourth port D of the four-way valve 92 and advances through the path 76 by the pump 95 to absorb the absorbed heat. Returned to the exchanger 14a.

一方、三方弁９４の第３ポートＣから第２ポートＢを進んだ暖房用循環液の一部は、貯湯槽１８の貯湯熱交換器１８ａへ導かれる。貯湯槽１８には、経路７５から水道水が導かれる。貯湯熱交換器１８ａでは、暖房用循環液と水道水の熱交換が行なわれ、暖房用循環液は水道水によって冷却され、水道水は暖房用循環液によって加熱される。
三方弁９６は、暖房運転時には、第２，第３ポートのみが開かれる。冷却された暖房用循環液は、三方弁９６の第３ポートＣから第２ポートＢを通って、経路７３経て、経路７６へ導かれる。ポンプ９５によって経路７６を前進し、吸収熱交換器１４ａに戻される。

暖房運転時には、冷媒蒸発器１２の蒸発熱交換器１２ａ内に大気熱交換用循環液が流れる。大気熱交換用循環液は、暖房運転時には、負圧タンク１０内の温度を一定に保つための加熱水となる。すなわち、吸収溶液の吸収能力を発揮させるためには、負圧タンク１０内の温度を一定に保つ必要があり、蒸発熱交換器１２ａ内に加熱された大気熱交換用循環液が流れることによって、温度が下降し過ぎることを禁止する。冷媒蒸発器１２の蒸発熱交換器１２ａを流れるうちに熱を奪われた大気熱交換用循環液は、経路８２から四方弁９０の第３ポートＣから第２ポートＢを通って、経路８１を経て、大気・液熱交換器２０に導かれる。大気・液熱交換器２０は、暖房運転時には大気からの吸熱のために利用され、送風機２１によって、大気から蒸発熱交換器１２ａで熱を奪われた大気熱交換用循環液に熱が加えられる。
大気・液熱交換器２０によって加熱された大気熱交換用循環液は、シスターン２２に導かれた後、圧縮式冷却・加熱装置３の圧縮式用熱交換器４０を経由し、経路７４から四方弁９２に導かれる。四方弁９２では第２ポートＢから第１ポートＡを通って、ポンプ９３によって経路８４を前進し、蒸発熱交換器１２ａに戻される。 During the heating operation, the atmospheric heat exchange circulating fluid flows in the evaporation heat exchanger 12a of the refrigerant evaporator 12. The circulating fluid for atmospheric heat exchange becomes heating water for keeping the temperature in the negative pressure tank 10 constant during heating operation. That is, in order to exhibit the absorption capacity of the absorption solution, it is necessary to keep the temperature in the negative pressure tank 10 constant, and the circulating fluid for atmospheric heat exchange flows in the evaporation heat exchanger 12a, Prohibit the temperature from dropping too much. The circulating heat for atmospheric heat exchange that has been deprived of heat while flowing through the evaporating heat exchanger 12a of the refrigerant evaporator 12 passes through the path 81 from the path 82 through the third port C to the second port B of the four-way valve 90. Then, it is guided to the atmosphere / liquid heat exchanger 20. The air / liquid heat exchanger 20 is used to absorb heat from the atmosphere during heating operation, and heat is added to the circulating fluid for atmospheric heat exchange that has been deprived of heat from the atmosphere by the evaporating heat exchanger 12a by the blower 21. .

The compression cooling / heating device 3 uses a compressible gas (hereinafter referred to as a heat medium) such as Freon and carbon dioxide as a working medium.

圧縮式冷却・加熱装置３には、冷房運転と暖房運転に応じて熱媒体の流れる方向を切替るための四方弁４２が設けられている。四方弁４２は反時計回りに、第１ポートＡが圧縮式用大気・液熱交換器３２からの入側、第２ポートＢが圧縮機３６からの入側、第３ポートＣが圧縮機３６への出側、第４ポートＤが圧縮式用熱交換器４０への出側となっている。
四方弁４２によって熱媒体の流れる方向が切替られることにより、暖房運転時には、圧縮式用大気・液熱交換器３２が熱媒体の蒸発器として作動し、圧縮式用熱交換器４０が熱媒体の凝縮器として作動する。以下の暖房運転時の説明では便宜のために、３２を蒸発器、４０を凝縮器という。 The compression-type cooling / heating device 3 is provided with a four-way valve 42 for switching the flow direction of the heat medium according to the cooling operation and the heating operation. In the four-way valve 42, the first port A is the inlet side from the compression atmosphere / liquid heat exchanger 32, the second port B is the inlet side from the compressor 36, and the third port C is the compressor 36. The fourth port D is the outlet side to the compression heat exchanger 40.
By switching the flow direction of the heat medium by the four-way valve 42, during the heating operation, the compression-type atmospheric / liquid heat exchanger 32 operates as a heat medium evaporator, and the compression-type heat exchanger 40 functions as a heat medium. Operates as a condenser. In the following description of the heating operation, for convenience, 32 is referred to as an evaporator and 40 is referred to as a condenser.

熱媒体は、高温高圧ガスの状態で凝縮器４０内に入る。熱媒体は、凝縮器４０内を通る際に、吸収式加熱装置２の大気熱交換用循環液と熱交換し、大気熱交換用循環液へ熱を付与しながら冷やされて凝縮する。これによって、吸収式冷却・加熱装置の大気熱交換用循環液がさらに加熱される。凝縮した熱媒体は、膨張弁３４に導かれ、膨張弁３４によって減圧され、膨張して冷却されて蒸発器３２に導かれる。蒸発器３２は、暖房運転時には、外気からの吸熱のために利用される。送風機３８によって、冷却された熱媒体に熱が加えられて熱媒体が蒸発する。蒸発した熱媒体は、四方弁４２の第１ポートＡから第３ポートＣを通って、圧縮機３６に導かれ、高温高圧ガスに圧縮される。高温高圧ガスに変化した熱媒体は、四方弁４２の第２ポートＢから第４ポートＤを通って、凝縮器４０に戻される。 The heat medium enters the condenser 40 in the state of high-temperature high-pressure gas. When passing through the condenser 40, the heat medium exchanges heat with the circulating fluid for atmospheric heat exchange of the absorption heating device 2, and cools and condenses while applying heat to the circulating fluid for atmospheric heat exchange. Thereby, the circulating fluid for atmospheric heat exchange of the absorption cooling / heating device is further heated. The condensed heat medium is guided to the expansion valve 34, decompressed by the expansion valve 34, expanded, cooled, and guided to the evaporator 32. The evaporator 32 is used for heat absorption from outside air during heating operation. Heat is applied to the cooled heat medium by the blower 38 to evaporate the heat medium. The evaporated heat medium passes from the first port A to the third port C of the four-way valve 42, is led to the compressor 36, and is compressed into high-temperature and high-pressure gas. The heat medium converted into the high-temperature and high-pressure gas is returned to the condenser 40 through the fourth port D from the second port B of the four-way valve 42.

圧縮式冷却・加熱装置３は、外気温度が低く、吸収式冷却・加熱装置２の大気・液熱交換器２０だけでは加熱能力不足となる場合に作動する。凝縮器４０内で大気熱交換用循環液に熱を付与することによって、吸収式冷却・加熱装置２の大気・液熱交換器２０だけでは十分に加熱されなかった大気熱交換用循環液の温度を上げる。 The compression-type cooling / heating device 3 operates when the outside air temperature is low and the air / liquid heat exchanger 20 of the absorption-type cooling / heating device 2 alone is insufficient in heating capacity. The temperature of the circulating fluid for atmospheric heat exchange that was not sufficiently heated only by the atmospheric / liquid heat exchanger 20 of the absorption cooling / heating device 2 by applying heat to the circulating fluid for atmospheric heat exchange in the condenser 40. Raise.

このように吸収式冷却・加熱装置と圧縮式冷却・加熱装置を併用することによって、外気温度が低い場合でも、負圧タンク内の温度を一定に保つための加熱に必要な温度まで大気熱交換用循環液を加熱することができる。外気温度が特に低いときは、吸収式冷却・加熱装置だけでは暖房や給湯が不能となる虞もあったが、このような事態も回避される。
また、暖房や給湯が不能となる程ではないが大気温度が低い場合も、大きな大気・液熱交換器を必要とせず、十分な暖房運転ないしは加熱運転を持続するために必要な温度まで大気熱交換用循環水を加熱することができる。
さらに、貯湯槽の入側の経路に発電機を備えることによって、発電機を利用して暖房用循環液が空調装置と貯湯槽で奪われる熱を予め補完すると共に、高温の排ガスの熱も高温再生器で無駄なく使用される。 By using the absorption cooling / heating device in combination with the compression cooling / heating device in this way, even when the outside air temperature is low, atmospheric heat exchange is performed up to the temperature required for heating to keep the temperature in the negative pressure tank constant. The circulating fluid for use can be heated. When the outside air temperature is particularly low, there is a possibility that heating and hot water supply may not be possible with only the absorption cooling / heating device, but such a situation is also avoided.
In addition, even if the air temperature is low, although heating and hot water supply are not disabled, large air / liquid heat exchangers are not required, and atmospheric heat is maintained up to the temperature required to maintain sufficient heating or heating operation. The replacement circulating water can be heated.
Furthermore, by providing a generator in the path on the inlet side of the hot water tank, the circulating fluid for heating is supplemented in advance with the air conditioner and the hot water tank using the generator, and the heat of the hot exhaust gas is also high. It is used without waste in the regenerator.

次に、図２を参照して、冷房運転について説明をする。吸収式冷却・加熱装置２では、冷房運転時には、四方弁９０，９２によって冷房用循環液と大気熱交換用循環液の流路が切替られ、冷媒蒸発器１２の蒸発熱交換器１２ａ内に冷房用循環液が流れ、冷媒吸収器１４の吸収熱交換器１４ａ内に大気熱交換用循環液が流れる。 Next, the cooling operation will be described with reference to FIG. In the absorption-type cooling / heating device 2, during the cooling operation, the flow paths of the circulating fluid for cooling and the circulating fluid for atmospheric heat exchange are switched by the four-way valves 90 and 92, and the cooling is performed in the evaporation heat exchanger 12 a of the refrigerant evaporator 12. The circulating fluid for use flows, and the circulating fluid for atmospheric heat exchange flows into the absorption heat exchanger 14a of the refrigerant absorber 14.

蒸発熱交換器１２ａで熱を奪われた冷房用循環液は、経路８２を経て四方弁９０の第３ポートＣから第１ポートＡを通って、経路８０を経た後、空調装置１６に供給される。空調装置１６はこの実施例においては水冷式である。
空調装置１６で冷房を行なって熱を吸収した冷房用循環液は、経路８５を経て四方弁９２の第３ポートＣから第１ポートＡを通って、ポンプ９３によって経路８４を前進し、蒸発熱交換器１２ａに戻される。 The cooling circulating fluid deprived of heat by the evaporative heat exchanger 12a is supplied to the air conditioner 16 via the path 82, the third port C of the four-way valve 90, the first port A, and the path 80. The The air conditioner 16 is water-cooled in this embodiment.
The circulating fluid for cooling that has been cooled by the air conditioner 16 and absorbed the heat passes through the path 85 from the third port C of the four-way valve 92 through the first port A, advances through the path 84 by the pump 93, and evaporates heat. Returned to the exchanger 12a.

冷媒吸収器１４の吸収熱交換器１４ａ内を流れる大気熱交換用循環液は、冷房運転時には、負圧タンク１０内の温度を一定に保つための冷却水となる。吸収熱交換器１４ａ内に冷却された大気熱交換用循環液が流れることによって、温度が上昇し過ぎることを禁止する。吸収熱交換器１４ａを流れるうちに吸収熱を吸収した大気熱交換用循環液は、経路７４を経て冷媒凝縮器８の凝縮熱交換器８ａ内に供給される。凝縮熱交換器８でさらに凝縮熱を吸収した大気熱交換用循環液は、凝縮熱交換器８ａから経路７２へ導出される。 The circulating fluid for atmospheric heat exchange flowing in the absorption heat exchanger 14a of the refrigerant absorber 14 serves as cooling water for keeping the temperature in the negative pressure tank 10 constant during the cooling operation. It is prohibited that the temperature rises excessively when the cooled circulating fluid for atmospheric heat exchange flows in the absorption heat exchanger 14a. The circulating fluid for atmospheric heat exchange that has absorbed the absorbed heat while flowing through the absorption heat exchanger 14 a is supplied into the condensation heat exchanger 8 a of the refrigerant condenser 8 via the path 74. The atmospheric heat exchange circulating fluid that has further absorbed the condensation heat in the condensation heat exchanger 8 is led out to the path 72 from the condensation heat exchanger 8a.

経路７２へ導出された大気熱交換用循環液は、発電機２８を経る。
三方弁９４は、冷房運転時には、第２，第３ポートのみが開かれ、大気熱交換用循環液は貯湯槽１８へ導かれる。貯湯熱交換器１８ａでは、大気熱交換用循環液と水道水の熱交換が行なわれ、大気熱交換用循環液は水道水によって冷却され、水道水は大気熱交換用循環液によって加熱される。
三方弁９６は、冷房運転時には、第１，第３ポートのみが開かれる。水道水で冷却された大気熱交換用循環液は、三方弁９６の第３ポートＣから第１ポートＡを通って、四方弁９０に導かれる。四方弁９０では第４ポートＤから第２ポートＢを通って、経路８１を経て、さらに大気・液熱交換器２０に導かれる。大気・液熱交換器２０は、冷房運転時には放熱のために利用され、送風機２１によって、水道水によって冷却し切れなかった液を冷却する。これによって、吸収熱交換器１４ａと凝縮熱交換器８ａで吸収された熱が大気に放出される。
大気・液熱交換器２０によって冷却された大気熱交換用循環液は、シスターン２２に導かれた後、圧縮式冷却・加熱装置３の圧縮式用熱交換器４０を経由し、四方弁９２の第２ポートＢから第４ポートＤを通って、ポンプ９５によって経路７６を前進し、吸収熱交換器１４ａに戻される。
一方、貯湯槽１８内で加熱された温水は、経路７７を経て給湯口１９へ供給される。 The circulating fluid for atmospheric heat exchange led to the path 72 passes through the generator 28.
In the cooling operation, only the second and third ports of the three-way valve 94 are opened, and the atmospheric heat exchange circulating fluid is guided to the hot water storage tank 18. In the hot water storage heat exchanger 18a, heat is exchanged between the circulating fluid for atmospheric heat exchange and tap water, the circulating fluid for atmospheric heat exchange is cooled by tap water, and the tap water is heated by the circulating fluid for atmospheric heat exchange.
Only the first and third ports of the three-way valve 96 are opened during the cooling operation. The circulating fluid for atmospheric heat exchange cooled with tap water is guided from the third port C of the three-way valve 96 through the first port A to the four-way valve 90. In the four-way valve 90, the fourth port D passes through the second port B, passes through the path 81, and is further guided to the atmosphere / liquid heat exchanger 20. The air / liquid heat exchanger 20 is used for heat dissipation during the cooling operation, and the blower 21 cools the liquid that cannot be completely cooled by the tap water. Thereby, the heat absorbed by the absorption heat exchanger 14a and the condensation heat exchanger 8a is released to the atmosphere.
The circulating fluid for atmospheric heat exchange cooled by the atmospheric / liquid heat exchanger 20 is guided to the cistern 22, and then passes through the compression heat exchanger 40 of the compression cooling / heating device 3, and passes through the four-way valve 92. From the second port B through the fourth port D, the pump 95 advances the path 76 and returns to the absorption heat exchanger 14a.
On the other hand, the hot water heated in the hot water storage tank 18 is supplied to the hot water supply port 19 through the path 77.

圧縮式冷却・加熱装置３では、四方弁４２によって熱媒体の流れる方向が切替られ、冷房運転時には、圧縮式用大気・液熱交換器３２が熱媒体の凝縮器として作動し、圧縮式用熱交換器４０が熱媒体の蒸発器として作動する。以下の冷房運転時の説明では便宜のために、３２を凝縮器、４０を蒸発器という。 In the compression-type cooling / heating device 3, the flow direction of the heat medium is switched by the four-way valve 42. During the cooling operation, the compression-type atmospheric / liquid heat exchanger 32 operates as a heat medium condenser, and the compression-type heat is supplied. The exchanger 40 operates as a heat medium evaporator. In the following description of the cooling operation, for convenience, 32 is referred to as a condenser and 40 is referred to as an evaporator.

熱媒体は、蒸発器４０内を通る際に、吸収式冷却・加熱装置２の大気熱交換用循環液と熱交換し、吸収式冷却・加熱装置２の大気熱交換用循環液の熱を冷却する。蒸発した熱媒体は、四方弁４２の第４ポートＤから第３ポートＣを通って、圧縮機３６に導かれる。圧縮機３６は、蒸発した熱媒体を高温高圧ガスに圧縮する。高温高圧ガスに変化した熱媒体は、四方弁４２の第２ポートＢから第１ポートＡを通って、凝縮器３２に導かれる。凝縮器３２には送風機３８が備えられており、冷房運転時には、放熱のために利用される。送風機３８によって、熱媒体の熱が大気に放出され、熱が奪われた熱媒体は凝縮液に凝縮される。凝縮液に変化した熱媒体は、膨張弁３４に導かれ、膨張弁３４によって減圧されて冷却された上で、蒸発器４０に戻される。 When the heat medium passes through the evaporator 40, it exchanges heat with the circulating fluid for atmospheric heat exchange of the absorption cooling / heating device 2, and cools the heat of the circulating fluid for atmospheric heat exchange of the absorption cooling / heating device 2. To do. The evaporated heat medium is guided from the fourth port D of the four-way valve 42 to the compressor 36 through the third port C. The compressor 36 compresses the evaporated heat medium into a high-temperature and high-pressure gas. The heat medium changed into the high-temperature and high-pressure gas is guided from the second port B of the four-way valve 42 to the condenser 32 through the first port A. The condenser 32 is provided with a blower 38, which is used for heat dissipation during cooling operation. The heat of the heat medium is released to the atmosphere by the blower 38, and the heat medium deprived of the heat is condensed into a condensate. The heat medium changed into the condensate is guided to the expansion valve 34, is decompressed by the expansion valve 34, is cooled, and is returned to the evaporator 40.

圧縮式冷却・加熱装置３は、外気温度が高く、吸収式冷却・加熱装置２の大気・液熱交換器２０だけでは冷却能力不足となる場合に作動する。蒸発器４０内で吸収式冷却・加熱装置２の大気熱交換用循環液の熱を吸収することによって、吸収式冷却・加熱装置２の大気・液熱交換器２０だけでは十分に冷却されなかった大気熱交換用循環液の温度を下げる。 The compression-type cooling / heating device 3 operates when the outside air temperature is high and the air / liquid heat exchanger 20 of the absorption-type cooling / heating device 2 alone is insufficient in cooling capacity. By absorbing the heat of the circulating fluid for atmospheric heat exchange of the absorption-type cooling / heating device 2 in the evaporator 40, the atmospheric-liquid heat exchanger 20 of the absorption-type cooling / heating device 2 alone was not sufficiently cooled. Reduce the temperature of the circulating fluid for atmospheric heat exchange.

このように吸収式冷却・加熱装置と圧縮式冷却・加熱装置を併用することによって、負圧タンク内の温度を一定に保つための冷却に必要な温度まで大気熱交換用循環液を冷却することができる。外気温度が特に高いときは、吸収式冷却・加熱装置だけでは冷房が不能となる虞もあったが、このような事態も回避される。
また、冷房が不能となる程ではないが大気温度が高い場合も、大きな大気・液熱交換器を必要とせず、十分な冷房運転を持続するために必要な温度まで大気熱交換用循環水を冷却することができる。 In this way, by using the absorption cooling / heating device and the compression cooling / heating device together, the circulating fluid for atmospheric heat exchange is cooled to the temperature required for cooling in order to keep the temperature in the negative pressure tank constant. Can do. When the outside air temperature is particularly high, there is a possibility that the cooling cannot be performed only by the absorption cooling / heating device, but such a situation is also avoided.
Even if the air temperature is not high enough to make cooling impossible, it is not necessary to use a large air / liquid heat exchanger, and the circulating water for air heat exchange is supplied to the temperature required to maintain sufficient cooling operation. Can be cooled.
