# Fan vs. Air-conditioning

At the office, we have the air-conditioning turned on like crazy, and we are therefore freezing...

The air-conditioning is coming from the roof.

My question is:

Does putting a fan blowing in the opposite direction of the air conditioning (i.e. from the desk to the ceiling) helps reducing the effect of the air conditioning (by effect, I mean cold and air flow)? In other words, does the fan can cancel out the AC effect, assuming for simplicity that the two air flows have the same speed / amplitude?

Any technical / non-technical explanations are welcome.
