Dedicated managers and engineers of data centres face multiple decisions every day, and choosing the right precision air conditioning systems for their extensive server rooms is one of them. The larger the facility is, the more servers there are—and these servers require a streamlined cooling system as opposed to individual air conditioning units. But why do these devices need cold air?
1. CONTROLLED, COOL CONDITIONS IN SERVER ROOMS
Data centre servers require low temperatures to prevent heat damage. They emit warmth whenever they manage and store information. These smart machines will malfunction if the temperature inside their server rooms reaches high levels. Precision air conditioning systems specifically designed for server rooms are needed to prevent this from happening. There are two choices for these cooling systems: CRAH and CRAC.
2. CRAH
Computer Room Air Handler (CRAH) units remove heat using fans, water chilling systems, and cooling coils. It blows air over the coils that are filled with chilled water, decreasing the temperature of a server room. CRAH can maintain an optimal condition by maintaining a set fan speed. It can also utilise the air outside the facility to cool the servers, lowering the energy it consumes.
3. CRAC
Computer Room Air Conditioner (CRAC) is similar to air conditioner units used in homes. Hot air passes through its coils that are brimming with refrigerants. CRAC keeps its chilly state with a compressor and removes excess heat by discharging air, water, or glycol mixture. CRAC systems have only two switches, on and off, but newer models may let you control their airflow.
4. THE BOTTOMLINE
The type of precision air conditioning structure for server rooms depends on the size and density of the servers. Mismatched server and cooling system sizes can cause thermal issues and mechanical problems. However, a sensing cable is required for both CRAH and CRAC systems to detect any water leaks.
