What are the advantages of modern data center cooling approaches, such as DX systems and chilled water systems?

Modern data center cooling approaches, like Direct Expansion (DX) systems and chilled water systems, offer improved efficiency, flexibility, and scalability compared to traditional methods. DX systems use refrigerant to cool the air directly, while chilled water systems use a central chiller plant to cool the water, which is then distributed to the data center. These modern approaches can provide higher cooling capacities, better air flow management, and reduced energy consumption.
