１よりれる。(f) Embodiment of the invention In FIG. 4, (8) has a heating device (9), and absorbs a refrigerant to increase the refrigerant concentration (hereinafter referred to as concentrated liquid).
A regenerator (10) is a regenerator (8) that gasifies and separates the refrigerant from the absorption liquid by heating and boiling the refrigerant.
The condenser (formerly) has a brine heat exchanger (7) that cools and liquefies the refrigerant gas flowing in from the condenser (10), and vaporizes the refrigerant liquefied in the condenser (10) under low pressure conditions. The evaporator is designed to take the heat of the internal prine into the machine as latent heat of vaporization, and the vaporized refrigerant is absorbed in the evaporator 01 (1 hot water is evaporator 01), so that the refrigerant vaporization function in the evaporator Ql) can be maintained. The evaporator (11) and absorber θ2) each have a liquid dispersion device (1,1+0
4), and the concentrated liquid that has absorbed the refrigerant in the absorber (12) is refluxed to the regenerator (8), where the refrigerant is separated again through line 1.

熱機として利用できるものである。In such a configuration, the liquid flowing through the evaporator heat exchanger (section 7) is cooled, and the liquid flowing into the absorber heat exchanger (6) is heated, so the cooling temperature is adjusted on the evaporator (7) side. It can be used as an absorption refrigerator when connected to a load, and as an absorption heater when connected to a load by adjusting the temperature of the liquid heated on the absorber (6) side.

ft, (16) and a second liquid distribution device (17) are provided, and the refrigerant (or absorption) liquid that has been roughly dispersed in the first liquid distribution device (16) is transferred to the first liquid distribution device (16) and a second liquid distribution device (17). The liquid is redispersed by the force of the liquid distribution device 2, and the liquid is made to flow uniformly down the surface of the heat exchanger tube (19) of the heat exchanger.

The liquid spreads in the axial direction of the core due to collision with the fins of the second distribution device, branching, and the action of surface tension of the liquid, and is suspended as droplets from each group of wound fins.

滴下させることができイ）。As shown in FIGS. 5 to 7, the second liquid dispensing device performs droplet dispersion by distributing the liquid to the fin groups at each pitch created by winding the strip material. Although the number of locations at which liquid is dripped from the device to the heat exchanger tubes of the heat exchanger depends on the amount of liquid, it is possible to increase the number of locations several times that of the first distribution device and allow the liquid to be dripped into the heat exchanger tubes of the heat exchanger (b).

ある。In addition, the liquid dispersion device of the present invention has a needle-like fin string material that functions to increase damage caused by liquid dripping, unlike the conventional liquid dispersion device. However, if the amount of liquid dripping from the distribution device is uneven, or even when the amount of liquid supplied by the liquid dispersion device is small, local It is possible to eliminate the uneven distribution of droplets and make the surface of the heat exchanger tube fully visible.
