Annotation
The physical processes in the absorptionheat and mass transfer devices with a mobile nozzle have been analyzed experimentally. The ratio between specific humidity change of atmospheric air in the absorberand the initial specific humidity was obtained. Lithiumbromidesolution(Li-Br)was used as an absorbent in the experiment. The efficiency ofthe absorption process increases with the increasing concentration of the absorbent. It was concluded that, if initial specific humidity of atmospheric airis from 11 to.20 gr/kg, solar absorption system providesquite effective decreasing of the specific humidity of this air flow.In this work it was provenexperimentallythat, the use of absorption systems in question contributes to providing comfortable air-conditioning in the wide range of outside air parameters (хgas= 13...20 gr/kg, and t = 25...40 оC).The potential of the proposed solar system for air-conditioning systems in the areas of Russian South is shown.
