Recently my office manager said this, after I requested a desk fan:
...using a fan causes a draught, which then leads the air conditioning to believe it’s cooler than it is and it then blows out even more hot air
I responded saying this is incorrect as fans simply move air, they don't make it cooler. It feels cool to us, but would make no difference to the air temperature measured by the air con.
I thought this would be an interesting question to post here, and would of course give me back-up. (For those interested, I got fed up waiting for a fan so I just bought my own.)
So my question is, is there any reason why the use of desktop fans in my office would make the air conditioning think it was getting cooler?
