Hi,
I have a conditioner in my server room but I have a curiosity regarding it - well more than a curiosity. I want to know how it's working.

My concept of a conditoner is that it blows cool air in that has been refrigerated and takes the hot air out of the room to refrigerate it. The cycle repeats so the air is always being recirculated rather than bringing in fresh air from outside.

When I put my hand up to the indoor unit I can feel the cool air being blown out but I can't understand where the hot air is being sucked out...
