ギーを付与するように構成していた。In an absorption air conditioner in which a cooling tower (29) is connected to (28b) by a cooling water circulation path (30), a heat exchange pipe (31) is bent and provided inside the evaporator (24), An indoor heat exchanger (23) is connected to the heat exchange pipe (31) through a cold water circulation path (32), and an evaporator (24) is connected to the heat exchange pipe (31).
) was configured to provide cold energy to the indoor heat exchanger (23) using cold water.
しかし、蒸発器（２４）の熱交換用パイプ（３１）が、
十分な熱交換能力を備えさせるためには大型で大重量に
なり、この点が例えば一般家庭で利用できるように吸収
式冷房機を小型・軽量化する上で大きな障害の１つにな
っている。However, the heat exchange pipe (31) of the evaporator (24)
Providing sufficient heat exchange capacity requires a large size and heavy weight, which is one of the major obstacles in making absorption air conditioners smaller and lighter so that they can be used in general households. .
本発明の目的は、蒸発器の内部の熱交換用パイプを無く
し、吸収式冷房機を小型・軽量化できるようにする点に
ある。An object of the present invention is to eliminate the heat exchange pipe inside the evaporator, thereby making it possible to reduce the size and weight of an absorption type air conditioner.
本発明の特徴構成は、蒸発器の冷媒受部に室内用熱交換

発させる撒布具に前記室内用熱交換器を冷媒還元路で接
続したことにあり、その作用効果は次の通りである。The characteristic configuration of the present invention is that an indoor heat exchanger is connected to a refrigerant receiving part of an evaporator by a refrigerant supply path, and the indoor heat exchanger is connected to a refrigerant return path to a spreading tool that spreads and evaporates refrigerant in the evaporator. The functions and effects are as follows.

冷却することによって、従来必要であった蒸発器内の大
型で大重量の熱交換用パイプを省略でき、蒸発器を従来
技術よりも大巾に小型・軽量化できるようになった。In other words, a refrigerant such as water is circulated between the evaporator and the indoor heat exchanger, and after being cooled through evaporation in the evaporator, the low-temperature liquid refrigerant collected in the refrigerant receiver is transferred to the indoor heat exchanger. By cooling the air with refrigerant in an indoor heat exchanger, the large and heavy heat exchange pipes inside the evaporator that were previously required can be omitted, and the evaporator can be made larger than with conventional technology. It has become possible to make it much smaller and lighter.
その結果、たとえ一般家庭で利用する場合でも設置場所
