Description

【０００１】
【発明の属する技術分野】
本発明は、冷房などの冷却運転に使用する三重効用吸収冷凍機に係わるものである。
【０００２】
【従来の技術】
この種の吸収冷凍機としては、例えば吸収器で冷媒を吸収した吸収液が低温熱交換器、中温熱交換器、高温熱交換器、高温再生器、高温熱交換器、中温再生器、中温熱交換器、低温再生器、低温熱交換器を順次経由して吸収器に還流するように配管した、例えば特開２０００−２５７９７６公報の図1、図２に提案された三重効用吸収冷凍機などが周知である。
【０００３】
前記特開２０００−２５７９７６公報に提案された、いわゆるシリーズフローの三重効用吸収冷凍機においては、再生圧力が大気圧を大きく超えて５００ｋＰａ程度にもなるために圧力容器となり、製造上の制約が大きくなる。また、主要部品の肉厚増加に伴うイニシャルコストの増加も避けられない。
【０００４】
一方、そのＣＯＰは１．５程度に過ぎず、製造コストの増加の割には熱効率の改善効果が乏しいと云った問題点があった。
【０００５】
【発明が解決しようとする課題】
したがって、製造コストが大幅に上昇することがないように、再生圧力の大幅な上昇を抑えることができ、且つ、ＣＯＰの改善が図れる三重効用吸収冷凍機を提供する必要があり、それが解決すべき課題となっていた。
【０００６】
【課題を解決するための手段】
本発明は上記従来技術の課題を解決するための具体的手段として、吸収液を加熱して吸収液に含まれる冷媒を蒸発分離し、冷媒が吸収できるように吸収液を再生する再生器として高温再生器、中温再生器、低温再生器を備えると共に、異なる温度の吸収液同士が熱交換する熱交換器として高温熱交換器、中温熱交換器、低温熱交換器を備えた吸収冷凍機において、前記吸収器で冷媒を吸収した吸収液が低温熱交換器、中温熱交換器、中温再生器、高温熱交換器、高温再生器、高温熱交換器、中温熱交換器、低温再生器、低温熱交換器を順次経由して吸収器に還流するように吸収液管を接続すると共に、前記中温再生器から高温再生器に至る吸収液管にポンプを設け、かつ、前記中温再生器から吐出した吸収液の一部を、前記ポンプの設置位置より下流側でそのポンプ設置箇所の直後から分岐し、高温熱交換器を経由して中温熱交換器に向かって流れる吸収液と合流させるための吸収液管をさらに設けた、吸収冷凍機を提供することにより、前記した従来技術の課題を解決するものである。
【０００７】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて詳細に説明する。
【０００８】
〔第１の実施形態〕
本発明の第１の実施形態を、図１に基づいて詳細に説明する。図中１は高温再生器、２は中温再生器、３は低温再生器、４は凝縮器、５は蒸発器、６は吸収器、７は低温熱交換器、８は中温熱交換器、９は高温熱交換器、１０〜１２は吸収液ポンプ、１３は冷媒ポンプであり、それぞれは図１に示したように実線で示した吸収液管と破線で示した冷媒管とで接続され、吸収液と冷媒がそれぞれ循環可能に構成されている。
【０００９】
なお、蒸発器５には冷水管１４が通され、吸収器６と凝縮器４には冷却水管１５が直列に通されている。
【００１０】
したがって、上記構成になる吸収冷凍機においては、吸収液ポンプ１０、１１および冷媒ポンプ１２を運転し、高温再生器１に添設した図示しないバーナで天然ガスなどを燃焼させると、高温再生器１においては燃焼熱により吸収液が加熱され、吸収液から蒸発分離した冷媒蒸気と、濃縮された吸収液とが得られる。
【００１１】
高温再生器１で生成された高温の冷媒蒸気は、中温再生器２に入り、中温再生器２内にある吸収液、すなわち吸収器６内で冷媒を吸収して吸収液濃度を下げ、低温熱交換器７と中温熱交換器８とで熱交換して加熱され、吸収液ポンプ１０により吸収器６から供給された吸収液を加熱して冷媒を蒸発させる。
【００１２】
中温再生器２で吸収液から蒸発分離した冷媒蒸気は、低温再生器３に入り、低温再生器３内にある吸収液、すなわち高温再生器１の図示しないバーナによる加熱により冷媒を蒸発分離して吸収液濃度が高められ、高温熱交換器９と中温熱交換器８とで熱交換して冷却され供給された吸収液を加熱して冷媒を蒸発させる。
【００１３】
低温再生器３で加熱され、吸収液から蒸発分離した冷媒蒸気は凝縮器４に入り、冷却水管１５内を流れる冷却水に放熱して凝縮し、中温再生器２、低温再生器３それぞれで吸収液に放熱して凝縮し、中温再生器２、低温再生器３それぞれから流入する冷媒液と一緒になって蒸発器５に入る。
【００１４】
蒸発器５に入って底部に溜まった冷媒液は、冷媒ポンプ１２により上方から散布され、冷水管１４の内部を流れる水と熱交換して蒸発し、冷水管１４の内部を流れる水を冷却する。
【００１５】
蒸発器５で蒸発した冷媒は吸収器６に入り、低温再生器３における加熱で冷媒を蒸発分離し、吸収液の濃度が一層高まった吸収液、すなわち吸収液ポンプ１２により低温再生器３から低温熱交換器７を経由して冷却供給され、上方から散布される吸収液に吸収される。
【００１６】
吸収器６で冷媒を吸収して吸収液濃度が低下した吸収液は、吸収液ポンプ１０の運転により低温熱交換器７と中温熱交換器８とで熱交換して加熱された後、中温再生器２に供給され、高温再生器１の図示しないバーナによる加熱で吸収液から分離して供給される冷媒蒸気により加熱され、冷媒蒸気を分離する。
【００１７】
中温再生器２で冷媒を蒸発分離した吸収液は、吸収液ポンプ１１により高温熱交換器９を経由し、その高温熱交換器９で加熱されて高温再生器１に戻される。
【００１８】
上記のように吸収冷凍機が運転されると、冷水管１４の内部を流れて蒸発器５に入った冷水は、蒸発器５内において冷媒の気化熱により冷却され、その冷却された冷水が冷水管１４を介して図示しない冷却負荷に循環供給できるので、冷房などの冷却運転が熱効率に優れた三重効用により行える。
【００１９】
そして、高温再生器１においては、中温再生器２で既に冷媒を１回蒸発分離した吸収液が流入し加熱されるので、高温再生器１で吸収液から蒸発分離する冷媒蒸気の量は吸収液が吸収器６から直接流入するときと比較すると減少する。そのため、高温再生器１内の圧力は顕著に抑制され、４００ｋＰａ程度となる。
【００２０】
しかも、蒸発器５、吸収器６を２段化するなどの熱効率の改善を図ることで、ＣＯＰは１．７程度に改善される。
【００２１】
〔第２の実施形態〕
本発明の第２の実施形態を、図２に基づいて説明する。この第２の実施形態の吸収冷凍機が、前記図１に示した第１の実施形態の吸収冷凍機と相違する点は、吸収液ポンプ１１の下流側の吸収液管にある。
【００２２】
なお、理解を容易にするため、この第２の実施形態の吸収冷凍機においても、前記図１に示した第１の実施形態の吸収冷凍機と同様の機能を有する部分には同一の符号を付した。
【００２３】
すなわち、図２に示した第２の実施形態の吸収冷凍機においては、吸収液ポンプ１１の下流側の吸収液管が２路に分岐し、一方の管路は前記図１に示した第１の実施形態の吸収冷凍機と同様に、中温再生器２から吐出した吸収液の大半、例えば７０〜９０％程度が高温熱交換器９を経由して高温再生器１に至り、他方の管路は中温再生器２から吐出した吸収液の一部、例えば１０〜３０％程度が高温再生器１で加熱濃縮されて吐出し、高温熱交換器９を出て中温熱交換器８に向かって流れている吸収液と合流するように設けられている。
【００２４】
したがって、この第２の実施形態の吸収冷凍機においては、中温再生器２から高温再生器１に供給される吸収液の量は、前記第１の実施形態の吸収冷凍機よりさらに減少し、高温再生器１において吸収液から蒸発分離する冷媒蒸気の量も減少するので、再生圧力をさらに抑えることが可能になる。
【００２５】
この場合も、蒸発器５、吸収器６を２段化するなどの熱効率の改善を図ることで、ＣＯＰは１．７程度に改善される。
【００２６】
したがって、前記図１に示した第１の実施形態の吸収冷凍機においても、また、図２に示した第２の実施形態の吸収冷凍機においても、従来のものより設計圧力が低下しているため、製造上の制約が緩和される。また、主要部品を圧肉部材で製作する必要もなくなるので、イニシャルコストの増加も回避できる。
【００２７】
なお、本発明は上記実施形態に限定されるものではないので、特許請求の範囲に記載の趣旨から逸脱しない範囲で各種の変形実施が可能である。
【００２８】
【発明の効果】
以上説明したように、本発明の吸収冷凍機によれば、高温再生器に流入する吸収液の量が減少し、それにより高温再生器で発生する冷媒蒸気の量が減少するので、高温再生器内の圧力上昇が抑制される。
【００２９】
そのため、製造上の制約が緩和されるので、主要部品を圧肉部材で製作する必要もなくなり、イニシャルコストの増加も回避できる。

[00 07 ]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[00 08 ]
[First Embodiment]
A first embodiment of the present invention will be described in detail with reference to FIG. In the figure, 1 is a high temperature regenerator, 2 is a medium temperature regenerator, 3 is a low temperature regenerator, 4 is a condenser, 5 is an evaporator, 6 is an absorber, 7 is a low temperature heat exchanger, 8 is a medium temperature heat exchanger, 9 Is a high-temperature heat exchanger, 10 to 12 are absorption liquid pumps, and 13 is a refrigerant pump. Each is connected by an absorption liquid pipe indicated by a solid line and a refrigerant pipe indicated by a broken line as shown in FIG. Each of the liquid and the refrigerant is configured to be circulated.
[00 09 ]
A chilled water pipe 14 is passed through the evaporator 5, and a chilled water pipe 15 is passed through the absorber 6 and the condenser 4 in series.
[00 10 ]
Therefore, in the absorption refrigerator having the above-described configuration, when the absorption liquid pumps 10 and 11 and the refrigerant pump 12 are operated and natural gas or the like is burned by a burner (not shown) attached to the high-temperature regenerator 1, the high-temperature regenerator 1 In the method, the absorption liquid is heated by the combustion heat, and the refrigerant vapor evaporated and separated from the absorption liquid and the concentrated absorption liquid are obtained.
[00 11 ]
The high-temperature refrigerant vapor generated in the high-temperature regenerator 1 enters the intermediate-temperature regenerator 2, absorbs the refrigerant in the intermediate-temperature regenerator 2, that is, absorbs the refrigerant in the absorber 6, and reduces the concentration of the absorbed liquid. Heat is exchanged between the exchanger 7 and the intermediate temperature heat exchanger 8 and heated, and the absorption liquid supplied from the absorber 6 is heated by the absorption liquid pump 10 to evaporate the refrigerant.
[00 12 ]
The refrigerant vapor evaporated and separated from the absorbing liquid in the intermediate temperature regenerator 2 enters the low temperature regenerator 3 and evaporates and separates the refrigerant by heating with the absorbing liquid in the low temperature regenerator 3, that is, the burner (not shown) of the high temperature regenerator 1. The absorption liquid concentration is increased, and heat is exchanged between the high-temperature heat exchanger 9 and the intermediate temperature heat exchanger 8 to cool the supplied absorption liquid and evaporate the refrigerant.
[00 13 ]
The refrigerant vapor heated by the low temperature regenerator 3 and evaporated and separated from the absorption liquid enters the condenser 4, dissipates heat to the cooling water flowing in the cooling water pipe 15, and is condensed by the medium temperature regenerator 2 and the low temperature regenerator 3. The liquid is dissipated and condensed, and enters the evaporator 5 together with the refrigerant liquid flowing from the intermediate temperature regenerator 2 and the low temperature regenerator 3.
[00 14 ]
The refrigerant liquid that has entered the evaporator 5 and accumulated at the bottom is sprayed from above by the refrigerant pump 12, evaporates by exchanging heat with the water flowing inside the cold water pipe 14, and cools the water flowing inside the cold water pipe 14. .
[00 15 ]
The refrigerant evaporated in the evaporator 5 enters the absorber 6, evaporates and separates the refrigerant by heating in the low temperature regenerator 3, and the absorption liquid whose concentration of the absorption liquid is further increased, that is, the absorption liquid pump 12 cools the refrigerant from the low temperature regenerator 3. It is cooled and supplied via the heat exchanger 7 and absorbed by the absorbing liquid sprayed from above.
[00 16 ]
The absorption liquid whose absorption liquid concentration has been reduced by absorbing the refrigerant in the absorber 6 is heated by exchanging heat between the low-temperature heat exchanger 7 and the intermediate temperature heat exchanger 8 by the operation of the absorption liquid pump 10, and is then regenerated at an intermediate temperature. The refrigerant vapor is heated by the refrigerant vapor supplied to the vessel 2 and separated and supplied from the absorbent by heating with a burner (not shown) of the high-temperature regenerator 1 to separate the refrigerant vapor.
[00 17 ]
The absorption liquid obtained by evaporating and separating the refrigerant in the medium temperature regenerator 2 is heated by the high temperature heat exchanger 9 via the high temperature heat exchanger 9 by the absorption liquid pump 11 and returned to the high temperature regenerator 1.
[00 18 ]
When the absorption refrigerator is operated as described above, the cold water flowing through the cold water pipe 14 and entering the evaporator 5 is cooled by the heat of vaporization of the refrigerant in the evaporator 5, and the cooled cold water is cooled by the cold water. Since it can be circulated and supplied to a cooling load (not shown) via the pipe 14, a cooling operation such as cooling can be performed by triple effect with excellent thermal efficiency.
[00 19 ]
In the high-temperature regenerator 1, since the absorption liquid that has already evaporated and separated the refrigerant once in the medium-temperature regenerator 2 flows and is heated, the amount of refrigerant vapor evaporated and separated from the absorption liquid in the high-temperature regenerator 1 is the absorption liquid. Is reduced as compared to when the gas flows directly from the absorber 6. Therefore, the pressure in the high temperature regenerator 1 is remarkably suppressed and becomes about 400 kPa.
[00 20 ]
In addition, the COP is improved to about 1.7 by improving the thermal efficiency such as the two stages of the evaporator 5 and the absorber 6.
[00 21 ]
[Second Embodiment]
A second embodiment of the present invention will be described with reference to FIG. The absorption refrigerator of the second embodiment is different from the absorption refrigerator of the first embodiment shown in FIG. 1 in the absorption liquid pipe on the downstream side of the absorption liquid pump 11.
[00 22 ]
For ease of understanding, in the absorption refrigerator of the second embodiment, the same reference numerals are used for the parts having the same functions as those of the absorption refrigerator of the first embodiment shown in FIG. It was attached.
[00 23 ]
That is, in the absorption refrigerator of the second embodiment shown in FIG. 2, the absorption liquid pipe on the downstream side of the absorption liquid pump 11 is branched into two paths, one of which is the first one shown in FIG. As in the absorption refrigerator of the embodiment, most of the absorption liquid discharged from the intermediate temperature regenerator 2, for example, about 70 to 90%, reaches the high temperature regenerator 1 via the high temperature heat exchanger 9, and the other pipe line. Is a part of the absorbing liquid discharged from the intermediate temperature regenerator 2, for example, about 10 to 30% is heated and concentrated in the high temperature regenerator 1 and discharged, and flows out from the high temperature heat exchanger 9 toward the intermediate temperature heat exchanger 8. It is provided to merge with the absorbing liquid.
[00 24 ]
Therefore, in the absorption refrigerator of the second embodiment, the amount of the absorption liquid supplied from the intermediate temperature regenerator 2 to the high temperature regenerator 1 is further reduced as compared with the absorption refrigerator of the first embodiment. Since the amount of refrigerant vapor that evaporates and separates from the absorbing liquid in the regenerator 1 also decreases, the regeneration pressure can be further suppressed.
[00 25 ]
Also in this case, the COP is improved to about 1.7 by improving the thermal efficiency such as the two stages of the evaporator 5 and the absorber 6.
[00 26 ]
Therefore, also in the absorption refrigerator of the first embodiment shown in FIG. 1 and in the absorption refrigerator of the second embodiment shown in FIG. 2, the design pressure is lower than the conventional one. Therefore, manufacturing restrictions are eased. In addition, since it is not necessary to manufacture the main parts with a compact member, an increase in initial cost can be avoided.
[00 27 ]
In addition, since this invention is not limited to the said embodiment, various deformation | transformation implementation is possible in the range which does not deviate from the meaning as described in a claim.
[00 28 ]
【The invention's effect】
As described above, according to the absorption refrigerator of the present invention, the amount of the absorption liquid flowing into the high temperature regenerator is reduced, thereby reducing the amount of refrigerant vapor generated in the high temperature regenerator. The pressure rise inside is suppressed.
[00 29 ]
As a result, manufacturing restrictions are alleviated, so that it is not necessary to manufacture the main parts with a compact member, and an increase in initial cost can be avoided.
