The diluting liquid that has fallen into the condensate reservoir (7) and is accumulated therein is discharged to the outside of the absorption condenser through a discharge line (not shown). On the other hand, the refrigerant flowing in the heat transfer tube (3) is discharged to the outside of the heat transfer tube while cooling the diluent.
（考案が解決しようとする課題） 前記第13,14図に示す従来の吸収凝縮器は，蒸気を伝
熱管（２）の表面に落下した希釈液により吸収，凝縮さ
せ，その際，蒸気の放出する熱量または希釈液の受熱し
た熱量を伝熱管（３）内を流れる冷媒より吸熱するもの
であり，伝熱管（３）の表面に濡れていない部分が存在
すれば，伝熱管（３）は伝熱作用を殆ど行わないことに
なる。(Problems to be Solved by the Invention) In the conventional absorption condenser shown in FIGS. 13 and 14, the vapor is absorbed and condensed by the diluting liquid that has dropped onto the surface of the heat transfer tube (2), and the vapor is released at that time. The amount of heat to be generated or the amount of heat received by the diluting liquid is absorbed by the refrigerant flowing in the heat transfer tube (3), and if there is an unwetted portion on the surface of the heat transfer tube (3), the heat transfer tube (3) will transfer heat. Almost no heat is applied.
仮に濡れていたとしても，伝熱管（３）の表面に形成
された液膜（または液滴）が下方の伝熱管（３）に速や
かに流下しないで同じ伝熱管（３）の外表面に長く止ま
っていたとすれば，吸収，凝縮が進み，飽和液に近づく
とともに吸収，凝縮能力も低下する。Even if it is wet, the liquid film (or liquid droplets) formed on the surface of the heat transfer tube (3) does not immediately flow down to the lower heat transfer tube (3), but is long on the outer surface of the same heat transfer tube (3). If it stopped, absorption and condensation proceed, and as it approaches a saturated liquid, the absorption and condensation capabilities also decrease.
即ち，上方から流下してきた希釈液は，伝熱管（３）
外表面に均一に広がり，吸収，凝縮した後，伝熱管
（３）下部から伝熱管（３）の管軸方向に沿って下流側
に均一に流下するのが理想的である。That is, the diluted liquid flowing down from above is transferred to the heat transfer tube (3).
Ideally, it uniformly spreads on the outer surface, is absorbed and condensed, and then uniformly flows from the lower portion of the heat transfer tube (3) to the downstream side along the tube axis direction of the heat transfer tube (3).
但し実際には，上流から液柱（または液滴）で流下し
ててき，伝熱管（３）の外表面に或る程度広がると，伝
熱管（３）上に流下してきた液柱（または液滴）の位置
より伝熱管（３）外表面に沿って円周方向下方に延ばし
た部分，即ち，伝熱管（３）下部付近から液柱（または
液滴）のまま流下し，それ以外の部分から流下するのは
僅かである。また下流に行く程，液柱（または液滴）の
合体が生じて，伝熱管（３）下部の管軸方向に存在する
液柱（または液滴）の間隔も長くなる。However, in reality, when the liquid column (or liquid droplet) flows down from the upstream side and spreads to some extent on the outer surface of the heat transfer tube (3), the liquid column (or liquid) flowing down on the heat transfer tube (3) is reached. A portion that extends circumferentially downward along the outer surface of the heat transfer tube (3) from the position of the droplet, that is, the liquid column (or droplet) flows down from the vicinity of the lower part of the heat transfer tube (3), and the other portion There is only a small amount of runoff. Further, as it goes downstream, coalescence of liquid columns (or droplets) occurs, and the interval between the liquid columns (or droplets) existing in the tube axis direction below the heat transfer tube (3) also becomes longer.
このことは実験例でも明らかである。これらのことに
より，伝熱管（３）上に流下してきて，伝熱管（３）下
部より流下してゆく液柱（または液滴）間を伝熱管
（３）の表面に沿って円周方向下方に延ばした部分，即
ち，伝熱管（３）下部付近に存在する液柱（または液
滴）は，伝熱管（３）の表面に長く止まっていなくて，
伝熱がスムーズに行われるが，他はこの部分よりも悪い
と言える。This is also clear in the experimental example. Due to these, the liquid columns (or droplets) that flow down onto the heat transfer tube (3) and flow down from the lower part of the heat transfer tube (3) are circumferentially downward along the surface of the heat transfer tube (3). The liquid column (or liquid droplets) existing near the bottom of the heat transfer tube (3), that is, near the bottom of the heat transfer tube (3), does not remain on the surface of the heat transfer tube (3) for a long time.
Heat transfer is performed smoothly, but it can be said that other parts are worse than this part.
また液膜が厚過ぎると，熱抵抗となり，伝熱を阻害す
ることも明らかである。その他，伝熱管（３）に接触し
ない希釈液は，冷媒との熱交換しないため，ごく僅かな
蒸気を吸収しただけで飽和液になり，伝熱に殆ど寄与し
ないことも明らかである。It is also clear that if the liquid film is too thick, it will cause thermal resistance and hinder heat transfer. In addition, it is also clear that the diluent that does not come into contact with the heat transfer tube (3) does not exchange heat with the refrigerant, and therefore becomes a saturated liquid by absorbing a very small amount of vapor and hardly contributes to heat transfer.
以上により，前記第13,14図に示す従来の吸収凝縮器

（７）に直接落下する希釈液は，伝熱に寄与していな
い。As described above, the conventional absorption condenser shown in FIGS. 13 and 14 has the following problems. That is, (I) the diluent that is sprayed from the spray pipe (2), collides with the inner wall surface of the shell (1) and flows down there, and the diluent that directly drops into the condensate reservoir (7) is used for heat transfer. Not contributing.

りがスムーズに行われなくて，伝熱が円滑に行われな
い。(II) The diluted liquid sprayed from the spray pipe (2) flows through the heat transfer pipe (3), coalescing of liquid columns (or droplets) occurs, and the more downstream the heat transfer pipe (3) The distance between the liquid columns (or droplets) existing in the tube axis direction becomes long. That is, as it goes downstream, the diluting liquid once attached to the heat transfer tube (3) is not smoothly replaced, and heat transfer is not smoothly performed.
（III）希釈液の流下方向の投影面の伝熱管（３）に散
布液を均一に濡れるように散布するには，投影面積が大
きい場合，散布管（２）の本数を増やす必要があって，
構造が複雑になる上に，コスト高になる。(III) In order to uniformly spread the spray liquid on the heat transfer pipes (3) on the projection surface in the downflow direction of the diluting liquid, if the projected area is large, it is necessary to increase the number of spray pipes (2). ，
The structure is complicated and the cost is high.

The diluting liquid flowing down is collected in the liquid spraying tray through the liquid collecting tray, and the diluting liquid in the liquid spraying tray is passed through the many diluting liquid spraying holes provided in the liquid spraying tray, and the lower heat transfer pipe (the refrigerant in the pipe is The heat transfer pipes are evenly distributed over the outer surface of the heat transfer pipes, and the steam of the heat transfer medium is formed between the outer periphery of the liquid distribution tray and the inner wall surface of the shell. Guide to the direction of the heat transfer tube through, the diluent flowing down the outer peripheral surface of the heat transfer tube is cooled by the refrigerant flowing in the heat transfer tube, to condense the steam, the following problems that occurred in the conventional absorption condenser, That is, the dilution that collides with the inner wall surface of the shell and flows down the inner wall surface. The liquid can be dropped directly without flowing down to the outer surface of the heat transfer tube, the diluting liquid adhering to the outer surface of the heat transfer tube cannot be replaced smoothly, and the number of diluting liquid spray tubes can be increased to It is not necessary to sprinkle the spray liquid on the heat transfer tubes on the projection surface in the downflow direction so as to be evenly wetted, so that the heat transfer performance can be improved and the cost can be reduced.
