Pneumatic to DDC in 20 Minutes - Non-invasive Retrofit of Pneumatic Thermostats
Presented by: Harry Sim of Cypress Envirosystems
Location: Legacy South 3
Pneumatic controls are still used in 70% of non-residential buildings, use more energy and require more
maintenance than traditional controls. Converting to DDC is often a costly process with long payback periods
and major building occupant disruption. In this session, attendees will learn about new non-invasive
technologies which install easily and cost much less than conventional DDC.
Presented by: Gene Ziegler of Parker Hannifan, Sporlan Divisions
Location: Legacy North 1
Refrigerant flow control valves work best when they are sized properly for their application. For many
applications, sizing is absolutely critical in order to achieve stable and optimal performance. This session will
discuss these issues and provide tips on how to convey this important material to your students.
Lab Exams: The Real Deal
Presented by: Carter Stanfield of Pearson
Location: Legacy North 2
This session will cover ways to administer hands-on exams in the lab, award defensible grades for lab
projects, and document the results.
Predictive Balancing Method to Balance HVAC Systems
Presented by: Robert Moss of Dwyer Instruments
Location: Legacy South 1
Predictive Balancing simplifies the Proportional Balancing method, taking the guesswork out of setting
dampers by determining the optimal flow rate for each terminal and reducing the number of steps required to
balance an HVAC system. An explanation of the method and field test results will be presented.
