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.
are you sure the ques is right thats on your mind? if not, elaborate
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.ankita15if a fan can give cold air in summer then y we cannt get hot air fm the same fan in winter???????😎
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.
