Adding an evaporative cooling tower to a chilled water loop can up the COP to 7ish, an air-cooled chiller by itself maxes out around 4. It’s almost twice as effective at removing heat. Air cooled chillers are fine for a commercial office building or tip-up warehouse, but data centers need to remove an enormous amount of heat.
