DX (Direct Expansion) Cooling is a method of air conditioning used in data centres, where refrigerant directly absorbs heat from the air passing through a cooling coil. Unlike chilled water systems, DX cooling does not require a separate chiller, making it a compact and efficient solution for smaller facilities or edge deployments. DX cooling systems are often used in conjunction with economizers to reduce energy consumption during cooler weather. They offer precise temperature control but may face limitations in scalability for larger facilities.
DX cooling uses refrigerants directly, whereas chilled water systems rely on water and a separate chiller to cool the air.
DX cooling is compact, cost-effective, and ideal for smaller or edge data centres requiring precise temperature control.
Yes, DX cooling is more suited for small to medium-sized facilities, with chilled water systems often preferred for larger, high-density data centres.
