Abstract

A first vane module, a second vane module, a third vane module, and a fourth vane module are sequentially controlled in successive order, thereby generating round swing wind swirling around an indoor unit. Consequently, it is possible to provide direct wind in the discharge direction of each vane module and to provide indirect wind to an indoor space deviating from the discharge direction of each vane module.
