Airflow management is crucial for energy efficiency of data centers

Data Center Journal, April 2008


Kishor Khankari


Air is the primary means of heat and moisture removal from data centers. The cold air supplied from the air conditioning system should pass through the servers, pick up the heat, and return back to the air conditioning system without mixing with the cold stream of supply air. This should be a single-pass loop. The hot and cold streams in the data center should be isolated from each other. Any short-circuiting that mixes hot air with the cold air or cold air that bypasses the servers without picking up the heat is detrimental to the energy efficiency of data centers. It is important to provide special attention to these airflow management aspects during the design and operation of data centers.
