Your question is not clear. Could you explain your question a bit in more detail?

A simple household fan doesn't give cold or hot air. It simply creates flow of air.

As vega said a fan creates a flow of air in the room. In summers you sweat, the flowing air evaporates the sweat and cools you. Try a simple experiment, blow air on the back of your hand, then wet the hand and again blow air over it, and feel the difference.

Well, I suppose you mean a device that can blow hot air, in the same context that a fan that can blow air to "cool" your skin.

There are heater devices out there that are shaped like desktop fans, but consists of a parabolic metal dish that emits heat from a heating element at the focal point. This dish also oscillates like fans do, and have a range of about 5-6m. Having a rotating blade might technically blow heated air to you, but that'll surely decrease the efficiency of the heating element.

Perhaps a hybrid device to incorporate a fan and heating element will suffice, though I doubt you'll actually have a synergy with them.

Fans are especially used in summer so their is no need of fan in winter because everybody like to safe themselves through other sources.
