A floor mounted mobile air circulator comprises an air driving mechanism 3 (i.e. fan, turbine, compressor etc...) that draws air 1 in from an inlet orifice 2 at or near a floor. The air is communicated from the air driving mechanism through an upright / vertical air flow directing duct 8 and through an outlet orifice 10 at a sufficient velocity utilising the Coanda effect towards a ceiling to displace heated air trapped adjacent the ceiling so as to reduce a differential temperature gradient of the air between the floor and ceiling. A main volume of air is entrained / drawn through lateral orifices 6 and does not pass through the air driving mechanism. The air circulator may be powered by mains electricity, an integral battery (fig 3) or separate battery (fig 4). Temperature sensors may record the air temperature at floor and ceiling levels and subsequently control the flow of air as a result of the recorded temperature gradient between the floor and ceiling (figs 5 & 6). The air circulator may comprise of a hose connection so that the air circulator may be connected to a pressurised air supply (fig 2). |
