FIELD: cooling blowers designed for cooling rooms with people in large industrial buildings. ^ SUBSTANCE: blower has diameter 4.5 - 12.0 m and it includes large number of blades. Each blade has tapered aerodynamic profile and it is driven by means electric motor for creating very large slowly moving air column. Such air column provides uniform smooth circulating air flow in inner rooms of building in order to promote natural process of cooling human bodies due to evaporation in all desired zones inside building. ^ EFFECT: enhanced efficiency of cooling. ^ 25 cl, 11 dwg |
