PURPOSE:To provide an attachment type fluidic element used at the air blowing opening of air conditioner, which operates to increase the deflection angle of air flow discharged from the air conditioner to a great extent and thus to obtain effective air conditioning effect. CONSTITUTION:At air blowing section 7, a fulidic element is constituted by upper plate 9, lower side wall 13, heat insulating member 14 adapted for preventing freezing, and lateral blade 12. Air from fan 3 passes through heat exchanger 5 and heater 6 and flows into section 7, where air flow is deflected vertically by the lateral blade 12 along the inclination angle of the same and also deflected horizontally by longitudinal blades 15, whereafter it is discharged therefrom. Here, it is possible to increase the downward inclination angle of air flow at the section 7, by employing heat insulating material 14, impermeable and low in surface roughness, and thereby effectually developing so-called Coanda effect. Alternatively, in place of said heating insulating material 14, a tape having the surface condition described as above may be applied on the surface of commonly used material which is air permeable and has a high surface roughness. |
