The airflow in a greenhouse of this design involves three main factors: the water drops; the foliage as a source of heat and water; and the fans. The interaction between the water drops and the air in their immediate neighbourhood causes cooling of the air and increases its specific gravity and, as a result of that, this air flows downwards and passes among the foliage. While among the foliage this air absorbs excess sensible and latent heat at the same time. The specific gravity of the air diminishes (especially among the upper foliage that is exposed to solar radiation) or increases (among the lower foliage), in accordance with the local heat balance, as a result of which a rising or falling flow, respectively, is initiated. In either case, there is a vertical flow which cause thorough mixing of the air in the greenhouse, which was manifested in the results obtained.
