Opportunity Knocks:
Managing airflow to
enhance data center cooling performance and promote
energy efficiency
by Kishor Khankari, PhD, Associate
Partner, Syska Hennessy Group
Cooling alone can add up to as much as 50% of a data center’s
total energy expenditure for the year, leaving
owners searching for opportunities to reduce traditionally
fixed costs. From picking the low hanging fruits to employing
CFD modeling, airflow management is the opportunity knocking
on the legacy data center’s door.
The first step in managing airflow is to divide computer
rooms into separate hot and cold aisles. Additionally, sealing
leaks in the data center floor, raising ceiling heights,
employing containment systems and optimizing air conditioning
unit placement within each space, will also sharpen operational
procedures that can reduce energy expenditure.
Secondly, employing CFD modeling can provide owners with
an opportunity to optimize computer room scenarios, all
in a cost effective way without the traditional expense
of trial and error.
Join Syska’s Kishor Khankari, a PhD in Computational
Fluid Dynamics and developer of several CFD
software tools, in his white paper Opportunity
Knocks, as he explores practical techniques
to enhance the legacy data center’s cooling
performance and further promote its energy efficiency.

Sit in for the Applications Program Track on
June 21 and hear him present Indoor
Airflow Simulation Strategies
for Design of Clean Spaces during
the Cleanroom Airflow Simulation,
Pressurization, Filtration
and Air Quality Control Strategies session.
Cleanroom Airflow Simulation, Pressurization, Filtration and
Air Quality Control Strategies Air quality management in
high-tech cleanrooms is a
very complex task. In addition to typical outside air and VOC
level controls, cleanrooms also require stringent room air cleanliness,
pressure and filtration controls to minimize airborne cross
contamination due to particle and microbial migrations along
airflows and air leakage paths. Studies on these complex and
dynamic characteristics will help develop better airborne control
tools and strategies which are often achieved automatically
and optimized through building management system. This seminar
addresses various cleanroom indoor airflow simulation methods,
effective airlock control, automatic suite pressurization and
new filtration technology down to very fine nano particles.
Session Type: Seminar 6
Session Start Time: 8:00 AM
Session End Time: 9:30 AM

On June 22, Terry Rodgers will chair
the Free Cooling Opportunities for Data Centers session.
This transactions session
will present on a variety
of issues that are pertinent
to strategies and technologies
for providing free-cooling
of data centers, telecommunications
facilities, and combinations
thereof. Issues of recent
concern include water-side
and air-side economizers,
enthalpy wheels, geothermal heat sinks, climatic and geographical
considerations, indoor and outdoor air quality concerns, and
implementation in existing and planned data centers.
