PURPOSE:To enhance the effect of air conditioning by a method wherein a mixed air outlet is spread in the horizontal direction and sloped downward and the angle of the slope of the mixed air outlet is adjustable. CONSTITUTION:Main bodies of unit air conditioners b1, b2... are arranged overhead and along a production line L, and the main body b1 covers a working zone a1, for example. Because the main bodies b1 and b2 cover the wide working zones a1 and a2, base faces d1 and d2, and d3 and d4 of air outlets c1 and c2, and c3 and c4 are respectively formed in an inverse pitched-roof shape and sloped downward. Since the widths of air conditioning zones vary depending upon the height of the working zones a1 and a2 above a floor F, the slope angles are adjustable.
