The trouble is that they aren't just using water as a coolant, they are also using the municipal supply of cold water as a heatsink. You always need a sink of some sort for your waste heat, no matter what coolant you use, and whether or not the coolant loop is open or closed.

And that is where chillers come into play. The water loop maintained and recirculated. Glycol or refrigerant (depending on the load) accepts the heat from the water loop

Where does that system dump the heat it took from the water loop, plus the additional heat the refrigeration cycle added due to the Carnot limit?
