What is Direct Expansion Cooling?
Direct Expansion (DX) Cooling is a highly efficient cooling method where refrigerant directly absorbs heat from the air within the cooling unit. Unlike chilled water systems that require additional heat exchange processes, DX cooling provides faster and more direct temperature control.
The cooling process includes:
- Warm air is drawn into the cooling unit.
- Refrigerant absorbs heat directly from the air.
- The cooled air is delivered back into the data center environment.
- Heat is transferred outside through the refrigeration cycle.
- Intelligent controls continuously optimize cooling performance.
This approach helps maintain stable temperatures while minimizing energy consumption and infrastructure complexity.
