The U.S. is among the countries bringing portable AC units to the Paris Olympics this summer since the Athletes' Village won't have any. Many athletes are worried about competing in extreme heat.
Heating/cooling works better with a heat sink, such as concrete. Water is also heavy, so laying it on top of the floor is far easier than suspending it from the ceiling. Also, in many places you will want to both heat and cool, and running heating and cooling in different locations costs up to twice as much. The easiest solution is to move the air, so fans do just fine.
