Chillers and Cooling Towers
Data center chillers and cooling towers are crucial. They remove heat from servers and other equipment. Chillers send chilled water through pipes to absorb heat, which is then sent to cooling towers.
The cooling towers release this heat into the air through evaporation. This keeps the data center’s temperature between 68-77°F (20-25°C).
CRAC/CRAH Units
CRAC (Computer Room Air Conditioner) and CRAH (Computer Room Air Handler) units are essential. They control the environment in data centers. They keep the humidity level between 40-60%.
CRAC units cool the air with refrigerants. CRAH units use chilled water from chillers. Advanced sensors in these units ensure precise control.
Redundancy and Backup Systems
HVAC redundancy is vital for data center design. It ensures the system keeps running even when something goes wrong. N+1 redundancy, with one extra unit ready to take over, is recommended.
Redundant systems and backup parts prevent costly downtime. They ensure there’s no single point of failure. This includes power supplies, cooling units, and control systems.
Data Center HVAC Design Considerations
Designing HVAC systems for data centers is key to their performance and life span. We’ll look at sizing, scalability, and right-sizing. These are crucial for a system that works well.
Sizing and Capacity Planning
Getting the size and capacity right is the first step. It’s about figuring out how much heat different equipment like servers produce. ASHRAE 90.4 says cooling uses half the energy in data centers, which is important to remember.
