Pumped Refrigerant EconoPhase Economizer for Data Centers
Steve Wagner, Emerson Network Power/Liebert
The new technologies of Pumped Refrigerant Economizer with digital scroll compressor and electronic
expansion valves may be new to you. However, at the end of this session, you will understand how the
Pumped Refrigerant Economizer along with digital scroll compressors are used to reduce the power
consumption within a Data Center. While everyone understands how standard compressors are used to move
refrigerant throughout a system, now you will know about the efficient way of using a fluid pump and bypass
the compressor to achieve the same conditions at a much lower operating cost.
Live Work Orders in the HVAC Program are They Worth the Risk?
Andrew Erbach, Elgin Community College and Eugene Silberstein, ESCO Group
This presentation will focus on issues related to permitting students to work on non school equipment. These
"live work orders" may range from bringing a window unit or a PTAC from home to work on as a student
project, to an instructor taking students on a service call. Each institution operates under different
administrative procedures and policies. This presentation will include an open discussion period regarding
issues to be considered when deciding whether or not to permit live work orders.
Taking a System Approach to Compressor Troubleshooting
Jamie Kitchen, Danfoss
This session will focus on the benefits of taking a broader perspective when trouble shooting compressors
that when done correctly, can reveal otherwise hidden issues that can affect compressor performance and
longevity. The goal is to avoid the trap of feeling the need to blindly 'replace or adjust' without first finding
out what went wrong and how to ensure it does not happen again.
Launching a Blended Learning Curriculum
Lou Vendrell, Lincoln Technical Institute
While the terminology of blended learning, hybrid program or online learning may vary, HVACR programs are
rapidly moving elements of their programs online. This session will cover the steps needed to launch an
effective blended program that begins with submitting regulatory documents and ends with setting up a lab
for effective hands on. This session will cover the different tools that can be used in order to enhance the
student experience with an online program.
