 You can be confident your CEUs will be recognized
–



Emerson Network Power CEUs are certified by IACET, the leading standards body in
continuing education training
We focus on delivering training outcomes, giving you substantive knowledge
that helps your career and can be measured
Post event testing and survey now required for CEUs
Post-event
CEUs, by IACET
–
Testing measures your knowledge about the learning objectives discussed in the
presentation
–
Those who indicated they
y want CEUs during
g webcast registration
g
will receive an email within
5 business days of the presentation, with a link to the online 10-question test and a short
presentation survey
–
You have 2 weeks after the email to take the test and do the survey
–
60% pass rate on test – you will be apprised via email of test results and can retake the test
once
–
After passing the test, you will receive your CEU certificate for download
CEUs
–
1 CEU = 10 content hours
–
This class is 1 hour, so you will receive 0.1 CEUs

Data Center Design and Control

Key to achieving and maintaining design
objectives
j
– Control
• iCOM controls to the Supply air but with Optimized Aisle
maintains the maximum Return Air Temperature
• Maintains capacity for 100% Availability
– Variable capacity (cooling and airflow)
– Measuring and Monitoring a tighter environment
– Some level of containment

Other Design Factors

Liebert DSE
– Simple, low maintenance and all Controls can be self contained with
iCOM and does not required a separate BMS
– Generally requires roof space for condensers
– Works best in climates with more than 35% of the dry bulb bin hours
temperatures at about 35 deg F below the RAT

Chilled Water
– Generally requires a BMS system for the chiller plant. Added cost?
– Economizer hours driven by adjusting the Leaving CW temperature
– Cost of water and treatment

Indirect Evaporative
–
–
–
–
–
Cost of water and treatment/ Availability
Does not take IT space – can be on the Roof or Side of building
Cooling support rooms may require other cooling solutions
Best in dry climates and higher RAT applications
Installation requires duct work – mostly operate in HAC config
48
Other Considerations

Installation costs
– As energy
gy cost come down, the first cost is the major
j
driver of the TCO
– Finding creative ways to bring down the installation
costs – factoryy built modules – eliminate on site
uncertainties


SCCR
Whit space use
White
– Cooling equipment in Galleries
– External to the building


BMS / Monitoring
Controlling to a Supply Air Temperature – means
to design to the Return Air Temperature
