How do chilled-water CRACs fit into the classification of air cooling vs. liquid cooling?

Chilled-water CRACs (Computer Room Air Conditioners) are typically deployed at the periphery of data centers and use a separate cooling loop that does not communicate thermally with the electronic equipment. In this case, the system is considered air-cooled, as only air needs to be supplied to the electronic equipment for operation. The chilled water serves as a heat sink, but it is not supplied directly to the entity being cooled.
