That data center likely still uses liquid to liquid heat exchangers with a chilled water loop and cooling towers to reject heat outside, but I could be wrong. P

Piping refrigerant around a massive building costs way more than chilled water, same goes for filling up the system, glycol and water is cheaper than refrigerant.
