に構成していた。Conventionally, as shown in Fig. 4, a generator (21) heated by a heat source such as a burner, a condenser (22), and an indoor heat exchanger (2
The evaporator (24) and absorber (25) connected to
The absorber (25) and generator (21) are connected to the absorption liquid circulation path (27).
), a heat exchange pipe (28a) is installed inside the case of the condenser (22) and absorber (25).
, (28b) are bent and provided, and these pipes (28b) are bent.
8a) and (28b) were connected to the cooling tower (29) by a cooling water circulation path (30), and the refrigerant and absorption liquid in the condenser (22) and absorber (25) were cooled. .

障害になっていた。However, because the cooling tower (29) is open to the atmosphere, troublesome water management and disposal of dirt and mud are required, which causes environmental deterioration due to the generation of bacteria and water droplets, and furthermore, the absorber (25) The heat exchange pipe (28b) and the cooling tower (29) must be large and heavy in order to have sufficient heat exchange capacity, and these points make it difficult to use absorption type air conditioners in general households. It was a big obstacle in doing so.
本発明の目的は、大気開放型のクーリングタワーに起因
する欠点を無くし、かつ、吸収器と室外用熱交換器を小
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 drawbacks caused by a cooling tower that is open to the atmosphere, and to make it possible to reduce the size and weight of an absorber and an outdoor heat exchanger.

設けたことにあり、その作用効果は次の通りである。[Means for Solving the Problems] A characteristic configuration of the present invention is that an outdoor heat exchanger for an absorber and a condenser is formed in a closed pipe type and air-cooled, and the condenser is connected to an absorption liquid receiving part of the absorber. The internal heat exchange pipe and the outdoor heat exchanger are connected in that order by an absorption liquid supply path, and an absorption liquid return path is provided for returning the absorption liquid from the outdoor heat exchanger to the absorber. Its effects are as follows.
つまり、吸収器と凝縮器に対する室外用熱交換器を閉管

る。In other words, the outdoor heat exchanger for the absorber and condenser is a closed pipe type and air-cooled, and the absorption liquid is circulated between the heat exchange pipes in the absorber and condenser and the outdoor heat exchanger. By cooling the liquid directly with air, it is possible to eliminate the conventionally required cooling tower that is open to the atmosphere, and
The temperature of the absorption liquid can be raised higher than in the conventional indirect heat exchange method, and heat can be radiated more efficiently. The outdoor heat exchanger can be made smaller and lighter, and the heat exchange pipe of the absorber can be omitted.
その結果、大気開放型のクーリングタワーが無いために
管理や保守が容易であり、かつ、環境衛生面において優

一般家庭においても便利に実用できる吸収式冷房機を提
供できるようになった。As a result, since there is no cooling tower that is open to the atmosphere, management and maintenance are easy, and it is superior in terms of environmental hygiene, and the absorber and outdoor heat exchanger can be made sufficiently small and lightweight.
It is now possible to provide an absorption type air conditioner that can be conveniently used in general households.
