本発明は、上記の如く構成されているので、次
の如き作用効果を有する。
Since the present invention is configured as described above, it has the following effects.
(1) 低ポテンシヤル凝縮器の冷却機構に導かれる
冷却媒体を、高ポテンシヤル凝縮器の冷却機構

シヤルエネルギを有効に利用することができ、
その利用範囲を広げ、貴重で高価な高ポテンシ
ヤルエネルギの消費を節約することができる。(1) By making the cooling medium led to the cooling mechanism of the low-potential condenser lower than that of the cooling medium led to the cooling mechanism of the high-potential condenser, the pressure inside the low-potential low temperature generator is lowered and the boiling point is lowered. It is possible to lower the temperature and effectively utilize the low potential energy at low temperature.
It can widen its range of use and save consumption of valuable and expensive high potential energy.
(2) また、吸収器を出たあとの溶液経路が、三つ

最も濃度の低いξ1溶液を供給すれば(1)の低圧に
よる作用のほかに、濃度が小なることによる沸
点上昇度の低下作用が働いて、低い沸点で沸騰
を行うことができ、(1)の効果を一層助長するこ
とができる。(2) Also, since the solution path after leaving the absorber is first led to the low-potential low-temperature generator among the three generators, the solution is led from the absorber to the potential low-temperature generator with the lowest vapor pressure. If the ξ 1 solution with the lowest concentration is supplied, in addition to the effect of the low pressure in (1), the boiling point can be boiled at a low boiling point due to the effect of lowering the boiling point rise due to the small concentration. The effect of (1) can be further promoted.
(3) また、溶液経路が、次に高温発生器を通り、
最後に高ポテンシヤル低温発生器に導かれてい

において最大濃度ξ4にまで濃縮されるため最大
濃度ξ4における温度T4は、従来の如き高温発
生器で最大濃度の濃縮が行われる場合のＳ点の
温度Tsよりも低く、また最高温度T3よりもTs
よりも低く、そのときの濃度ξ3もξ4より小であ
るので、機器や管路の腐食を防止することがで
きる。(3) Also, if the solution path then passes through a high temperature generator,
Finally, by being led to a high-potential low temperature generator, the solution is concentrated to a maximum concentration ξ 4 under a relatively low pressure P L2 , so that the temperature T 4 at the maximum concentration ξ 4 is lower than the conventional high temperature T s lower than the temperature at point S when maximum concentration occurs in the generator T s and lower than the maximum temperature T 3
Since the concentration ξ 3 at that time is also smaller than ξ 4 , corrosion of equipment and pipes can be prevented.

冷却管１９におけるよりも低温の冷却水が通る。 18 and 19 are cooling pipes for condensation, and pipe line 2
0, 21, and 22 cause a cooling medium such as cooling water to flow. Cooling pipe 18 of low potential condenser C 1
is located upstream of the cooling pipe 19 of the high potential condenser C 2 in terms of the flow of the cooling medium, and therefore the cooling water at a lower temperature than in the cooling pipe 19 passes therethrough.

運転時の溶液サイクルをlogP−Ｔグラフにて
第２図に示す。 The solution cycle during operation is shown in Figure 2 as a logP-T graph.
冷却管１８内の冷却媒体温度は、冷却管１９内
のものより低いので、低ポテンシヤル凝縮器C1
内の凝縮温度及び飽和蒸気圧は、高ポテンシヤル
凝縮器C2内の凝縮温度及び飽和蒸気圧よりも低
い。従つて第２図における低ポテンシヤル低温発
生器GL１内の蒸気圧PL１は、高ポテンシヤル低
温発生器GL２内の蒸気圧PL２よりも低く、従つ
て蒸気温度も前者の内部の方が低い。 Since the coolant temperature in the cooling pipe 18 is lower than that in the cooling pipe 19, the low potential condenser C 1
The condensing temperature and saturated vapor pressure within the high potential condenser C2 are lower than those within the high potential condenser C2. Therefore, the steam pressure PL1 in the low-potential low-temperature generator GL1 in FIG. 2 is lower than the steam pressure PL2 in the high-potential low-temperature generator GL2, and therefore the steam temperature is also lower inside the former.
一方、溶液の沸点は濃度が低い方が低い。 On the other hand, the lower the concentration, the lower the boiling point of the solution.
従つて、最も蒸気圧が低い低ポテンシヤル低温
発生器GL１に、吸収器Ａから導かれた最も濃度
の低い低濃度（ξ1）溶液を供給すれば最も低い沸
点にて沸騰を行うことができる。即ち低い温度の
低ポテンシヤルエネルギにても溶液を濃縮せしめ
ることができる。 Therefore, if the lowest concentration (ξ 1 ) solution derived from the absorber A is supplied to the low potential low temperature generator GL1, which has the lowest vapor pressure, boiling can be performed at the lowest boiling point. That is, the solution can be concentrated even at low temperature and low potential energy.
しかる後溶液は高温発生器GH及び高ポテンシ
ヤル低温発生器GL２において高ポテンシヤルの
補助熱源により二重効用吸収冷凍サイクルを行
う。このように、溶液経路が、次に高温発生器
GHを通り、最後に高ポテンシヤル低温発生器
GL２に導かれることにより、溶液は、比較的低
い圧力PL２下において最大濃度ξ4にまで濃縮さ
れるため最大濃度ξ4における温度T4は、従来の
如き高温発生器で最大濃度の濃縮が行われる場合
のＳ点の温度Tsよりも低く、また最高温度T3も
Tsよりも低く、そのときの濃度ξ3もξ4より小で
あるので、機器や管路の腐食を防止することがで
きる。 Thereafter, the solution undergoes a dual effect absorption refrigeration cycle with a high potential auxiliary heat source in a high temperature generator GH and a high potential low temperature generator GL2. In this way, the solution path is then
Pass through GH and finally high potential low temperature generator
By being led to GL2, the solution is concentrated to the maximum concentration ξ 4 under a relatively low pressure PL2, so the temperature T 4 at the maximum concentration ξ 4 is the same as that at which concentration to the maximum concentration can be achieved with a conventional high temperature generator. lower than the temperature T s at point S when
Since it is lower than Ts and the concentration ξ 3 at that time is also smaller than ξ 4 , corrosion of equipment and pipes can be prevented.
しかして、熱源としては低ポテンシヤルエネル
ギを優先的に使用し、不足分を高いポテンシヤル
エネルギにて補うよう制御する。例えば冷水出口
温度が一定となるように流量制御弁２４及び２６

値に達するまでは流量制御弁２６は開かず、流量
制御弁２４が最大開度に達し、なおかつ熱源が不
足する時のみ流量制御弁２６を開いて高ポテンシ
ヤルエネルギを補うようにする。 Therefore, low potential energy is preferentially used as a heat source, and control is performed to compensate for the deficiency with high potential energy. For example, the flow control valves 24 and 26
When controlling the flow rate control valve 24, the flow rate control valve 26 does not open until the opening degree of the flow rate control valve 24 reaches the maximum value, and the flow rate control valve 26 does not open until the flow rate control valve 24 reaches the maximum opening degree and the heat source is insufficient. to compensate for high potential energy.
なお管路４と管路８を連結する配管３０と弁３
１を設け、低ポテンシヤルエネルギだけで足りて
いる場合には、この連絡配管３０に溶液を流し、
吸収器Ａへ送り、単効用のサイクルとすることも
できる。 Note that the pipe 30 and valve 3 connecting the pipe 4 and the pipe 8
1, and if only low potential energy is sufficient, pour the solution into this connecting pipe 30,
It can also be sent to absorber A to create a single-effect cycle.
本実施例のものは、以上の如く構成され作用す
るので、低温の低ポテンシヤルエネルギを有効利
用することができ、高ポテンシヤルエネルギの消
費を節減することができる。 Since the device of this embodiment is constructed and operates as described above, low-temperature low-potential energy can be effectively utilized, and consumption of high-potential energy can be reduced.
また、前記の如く蒸気圧PL１をPL２よりも低
くすることができるので、蒸発器Ｅに戻す冷媒液
の温度は、冷媒サイクルに最終通路を低ポテンシ
ヤル凝縮器C1とすることにより低くすることが
できるので、冷媒循環量の単位重量当たりの冷媒
能力が増すことにより効率の向上が得られる。 Furthermore, since the vapor pressure PL1 can be made lower than PL2 as described above, the temperature of the refrigerant liquid returned to the evaporator E can be lowered by providing the final passage in the refrigerant cycle with the low potential condenser C1 . Therefore, efficiency can be improved by increasing the refrigerant capacity per unit weight of refrigerant circulation.
また、低ポテンシヤルエネルギの温度は、低温
溶液熱交換器HELの低濃度溶液出口（第２図の

まで利用できる場合は、単効用サイクルとして利
用できることになる。 Moreover, the temperature of the low potential energy can be slightly higher than the low concentration solution outlet (point in FIG. 2) temperature of the low temperature solution heat exchanger HEL. In this case, the low potential energy can be used as a preheat for the absorption solution cycle even though the amount of heat or temperature of the low potential energy is low enough to barely heat up to a point. If it can be used to a point state or higher, it can be used as a single-effect cycle.
蒸気圧PL１は低ければ低い程点の状態を定
める低濃度溶液の温度を低くすることができるの
でできるだけ低温の冷却水を低ポテンシヤル凝縮
器C1の冷却管１８に通すことが好ましい。 The lower the vapor pressure PL1 is, the lower the temperature of the low-concentration solution that determines the point state can be lowered, so it is preferable to pass cooling water as low as possible through the cooling pipe 18 of the low-potential condenser C1 .
吸収器Ａにも冷却管２９が備えられており、こ

る。 The absorber A is also equipped with a cooling pipe 29, and a common cooling medium can be used for this. Even in that case, it is preferable to always pass the cooling medium through the low potential condenser C1 first, so the following combinations of cooling medium flow orders are used.
