CRAC Systems: One of the Oldest and Most Widely Used Cooling Options for Data Centers

One of the oldest and most widely used types of cooling systems in data centers is the CRAC (Computer Room Air Conditioner). These systems are specifically designed to cool the internal air of the data center and focus directly on server equipment.

How CRAC Systems Work

CRAC systems operate using mechanisms similar to residential or commercial air conditioning systems, including:

• Compressor: Compresses the refrigerant to drive the cooling cycle.

• Refrigerant: Absorbs heat and transfers it outside the environment.

• Cooling Coils: Reduce the temperature of passing air.

• Fan: Distributes the cooled air efficiently.

These systems extract the heat generated by data center equipment and transfer it outside the environment.

Features and Benefits of CRAC

• Cold Air Circulation: CRAC systems deliver cold air directly to server equipment using raised floors or distribution ducts.

• Continuous Operation: They work 24/7 to maintain stable temperatures and prevent overheating due to high heat loads.

• Cost-Effective Performance: A reliable and economical solution for data centers requiring consistent cooling.

Conclusion

CRAC systems remain a reliable and cost-effective choice for cooling data centers, providing a stable and efficient solution for temperature management.
