FIELD: instrument engineering. ^ SUBSTANCE: device, system and method aim at generation of column air flow. An air handling device comprises a body, an in-built driving wheel that generates downward air flow and in-built blades mounted in close proximity to the driving wheel at specified distance and serving to generate straight-line air flow. The device generates air flow that essentially holds column shape at the considerable distance. The method consists in generating air flow that essentially holds column shape at the considerable distance and is directed from ceiling to floor to mix air layers of air of various temperatures in an enclosed air space. Besides, the method consists that warm air directed from ceiling to floor accumulates thermal energy in floor, in devices being thereon and thereunder. If ceiling is colder than floor, accumulated energy is released. ^ EFFECT: reduced power consumption and noise level. ^ 32 cl, 24 dwg |
