Description

  The present invention relates to a cooling / heating roof fan.

  A roof fan installed on a roof of a factory or the like is conventionally used only for sucking outside air and sending it indoors for indoor ventilation.

  By the way, due to global warming, the temperature often increases abnormally in summer. However, since the conventional roof fan simply takes the outside air indoors and circulates it, if the outside air itself is at a high temperature, the indoor air temperature remains high, which is not preferable as a work environment. There is also a risk of affecting the machines and devices that are operating. For this reason, a separate indoor cooling device is required, which requires extra costs.

  Further, since the conventional roof fan blows cold air indoors in winter, the driving of the fan is stopped.
