Data Center Cooling Equipment
Cooling is one of the most important infrastructure considerations because computing equipment continuously produces heat during operation.
Data center cooling systems must maintain appropriate environmental conditions while avoiding unnecessary energy consumption.
The Department of Energy’s data center efficiency guidance emphasizes evaluating IT equipment, environmental conditions, air management, and cooling systems together.
1. Precision Air Conditioning
Precision cooling systems are designed for environments containing computing and electronic equipment.
Unlike ordinary comfort cooling, data center cooling must account for equipment heat loads, airflow distribution, temperature monitoring, and operating reliability.
CRAC and CRAH systems are common examples of room-level cooling equipment.
2. In-Row Cooling Systems
In-row cooling places thermal management equipment within or alongside rows of server racks.
This configuration can help address localized heat loads and reduce airflow problems in higher-density environments.
For example, Vertiv lists the Liebert CRV in-row cooling system with published capacities of 32–50 kW.
This model is designed for high-density applications requiring targeted thermal management.
Official product information: https://www.vertiv.com/en-us/products-catalog/thermal-management/in-row-cooling/
3. Liquid Cooling Systems
Liquid cooling is increasingly relevant for high-density computing infrastructure, including AI and high-performance computing environments.
Unlike conventional air cooling, liquid cooling transfers heat through a liquid-based thermal management system.
Common technologies include:
- Direct-to-chip liquid cooling.
- Rear-door heat exchangers.
- Liquid cooling distribution units.
- Facility water loops.
- Specialized heat rejection equipment.
A Cooling Distribution Unit (CDU) provides an interface between cooling loops and the IT equipment, managing aspects such as fluid delivery and operating conditions.
Liquid cooling may be appropriate when equipment power density exceeds the practical capabilities of the planned air-cooling architecture.
However, it introduces additional requirements involving plumbing, fluid management, monitoring, maintenance, and equipment compatibility.
4. Hot-Aisle and Cold-Aisle Containment
Airflow organization is another important part of data center cooling.
Hot-aisle and cold-aisle arrangements organize equipment orientation to help manage the movement of incoming cool air and exhausted hot air.
Containment systems can help reduce the mixing of hot and cold air.
Schneider Electric provides data center solutions that include in-row cooling, in-room cooling, and aisle containment.
