Improve Data Center Cooling in Four Strategic Steps
Balancing cost efficiency with environmental responsibility is often challenging. However, data centers present an ideal opportunity to align these goals, fostering both economic savings and a reduced carbon footprint. With the ongoing rise in energy expenses and data center demands, optimizing cooling efficiency remains a priority. By adopting best practices, you can enhance your current data center’s cooling performance and prepare for future advancements.
Effective Sealing for Data Center Optimization
Proper sealing is crucial for data centers, serving as the cornerstone for maximizing cooling efficiency. Inadequate sealing can lead to cooling inefficiencies and increased humidity. Consider these steps to ensure an effective seal:
- Ensure doors remain closed consistently.
- Create a vapor barrier using materials like plastic film, vapor-retardant paint, vinyl wall coverings, and flooring systems, which is a cost-effective method for controlling the environment.
- Seal any apertures around pipes and cables entering through walls and floors.
- Conduct a thorough assessment to identify and rectify any sealing weaknesses.
Optimizing Airflow with Hot-Aisle/Cold-Aisle Configuration
The hot-aisle/cold-aisle design efficiently transfers heat from your equipment while minimizing energy usage. This setup promotes optimal airflow, enhances the capacity of computer room precision air conditioners (CRAC), and reduces the energy load on each unit.
This system arranges racks to face each other, drawing air from the cold aisle and expelling hot air from the back, forming a hot aisle. Placing CRAC units perpendicularly to these aisles boosts the return air temperature, further increasing efficiency.
Implementing Aisle Containment Systems
After establishing a hot-aisle/cold-aisle configuration, the next step involves implementing hot or cold aisle containment. This approach prevents the mixing of hot and cold air between aisles. By sealing aisles with panels above and between racks and installing doors at each end, you can significantly boost cooling capacity and energy efficiency.
This containment strategy allows for enhanced cooling of higher heat loads per rack by raising the return air temperature to the CRAC units. More insights can be found in the white paper “Focused Cooling Using Cold Aisle Containment”.
Advanced Cooling with Intelligent Systems
Using intelligent control systems like the Liebert DSE, your cooling system can operate more efficiently by minimizing energy use and providing advanced diagnostics. The Liebert DSE is up to 70% more efficient and uses technologies like dynamic fan control and compressor modulation to optimize energy distribution.
The Liebert iCOM with Optimized Aisle Control allows for independent compressor and fan operation to better match IT load and airflow needs. This optimized operation results in warmer return air to the cooling units, preventing overcooling and saving energy.
