現象を起こして希溶液の流れが阻害されてしまう。(Conventional technology and its problems) For the heat exchange of the solution in the absorption cycle, conventionally, a heat exchanger such as a shell tube type heat exchanger or a double tube type heat exchanger is installed between the regenerator and the absorber. And go. In such a heat exchanger, when trying to evaporate the refrigerant from the dilute solution in order to improve the efficiency, a so-called vapor lock phenomenon occurs and the flow of the dilute solution is hindered.

In the present invention, a heat exchange vessel 2 having an upper part communicated with a regenerator 1 in an absorption cycle is provided side by side. At the same time, a heat transfer tube 3 is provided in the heat exchange vessel 2 to form a concentrated solution supply path A from the regenerator 1 to the absorber 4 through the heat transfer tube 3 and the heat exchange tube The dilute solution supply path B extends to the upper part of the vessel 2, and the solution supply path C extends from the lower part of the heat exchange vessel 2 to the regenerator 1.

The dilute solution thus supplied into the container 2 is heated by exchanging heat with the high-temperature concentrated solution flowing through the heat transfer tube 3 through the heat transfer tube 3, and a part of the refrigerant evaporates or boils. The evaporated or boiled refrigerant vapor communicates with the upper space of the regenerator 1 through the upper communication part 6, and flows from a refrigerant vapor outlet 7 at a suitable position toward a condenser (not shown). On the other hand, the remaining solution that has released a part of the refrigerant stays at the bottom of the heat exchange container 2 and is sequentially supplied to the regenerator 1 through the solution supply path C, where it is subjected to regeneration and generation of refrigerant vapor.
The concentrated solution that has exchanged heat with the dilute solution has a lower temperature and flows to the absorber 4.

きる。As described above, in the present invention, the upper part is communicated with the regenerator 1, and in the heat exchange vessel 2 in which the steam is communicated,
Heat exchange between the concentrated solution from the regenerator 1 flowing through the heat transfer tube 3 and the dilute solution from the absorber 4 supplied to the container 2 does not cause vapor lock even when the refrigerant is evaporated or boiled from the dilute solution. Efficient heat exchange of the solution can be performed.
