Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the appended claims will include such modifications and variations as long as they fall within the spirit of the invention.

According to an embodiment of the present invention, it is possible to provide a ceiling fan to generate the flow and circulation of the air, and to apply the embodiments of the present invention to a heating and cooling device, an air conditioning unit and an air conditioning system having a ceiling fan for industrial use can do.

Claims (6)
