Cooling Data Center Without Raised Floor

Typical raised floor cooling capacities can be determined per the following table.

Cooling data center without raised floor. Allow for increasing cooling capacity without load impact 4. Many of the traditional reasons for the raised floor no longer exist and some of the costs and limitations that a raised floor creates are avoidable by using hard floor designs. The accessible raised floor plenum facilitates future changes such as added cooling or electrical infrastructure it is easier to run new conduits or piping under a raised floor than it is to run overhead in a live data center. Maintaining proper environmental conditions within non raised floor data centers doesn t have to be complex if you use the right metric in your control strategy.

Data center cooling best practices. That warm rises and is collected cooled and returned to beneath the floor to repeat the process. Cold air from a computer room air conditioner crac or computer room air handler crah pressurized the space below the raised floor. Robert tozer director of operational intelligence ltd however though not efficient the raised floor in association with air.

In our ibxs with raised floor we use the underfloor plenum primarily for air delivery and routing of. One can create a computer model of the whole data center complete with the raised floor air conditioning units perforated tiles and server racks. Provide for cooling distribution improvements without load impact. Raised floor here cool air is supplied from underneath an elevated perforated floor.

Cooling in a data center is an excellent application for computational fluid dynamics cfd. It offers a new paradigm for meeting the cooling challenge. This paper discusses factors to consider when determining whether a data center should use a raised floor or a hard floor design. Systems which mostly use raised floor cooling i think we will still continue to see raised floor cooling designs and for valid reasons dr.

Legacy cooling and the end of raised floor for decades computer rooms and data centers utilized raised floor systems to deliver cold air to servers. Raised floor data center raised floor. For more information on controlling data center cooling using delta t read the vertiv white paper overcoming the challenges in cooling non raised floor data centers. Complexity involved in balancing variable air delivery across a raised floor.

This air will collect the heat and rise up towards the ceiling. But the benefits of eliminating raised floors are too great to ignore prompting the need for a fresh approach to cooling design in a non raised floor data center environment. The conditioned cold air will be forced by a fan in the crac unit into the void under the floor and small holes or grills in the floor tiles will allow the air to leave the void in strategic places.
