Down flow cooling systems are the most common design of data centre cooling systems, and are named as such due to the way the CRAC units handle the air, with hot exhaust air entering through the top, passing over the internal cooling systems within, before being ejected out of the bottom of the unit. CRAC units, or computer room air conditioning units, are configured as either Down Flow Plenum or Down Flow Front Displacement

The overall design of your data centre cooling systems should be sized to the I.T. load, with the ability to expand without disruption to critical services which avoids energy wastage due to system losses. It is vital to build redundancy into your data centre cooling systems, as CRAC units require frequent servicing every 3 months as a minimum. Redundant systems provide additional resilience and facilitate repairs during maintenance checks.

It's paramount that down flow CRAC units are efficient and have a high sensible heat ratio (SHR), EC rated fans and electronic expansion values. Selecting the right cooling system will also have a significant effect on the PUE or DCiE.
