HVACR Controls & Sensors: Their Design and Operation
Joe Marchese, Refrigeration Service Engineers Society
Napa Room C
HVACR systems use a variety of sensors to monitor and control their operation. These sensors
convert physical quantities such as temperature, pressure, and flow into an electrical signal
which can be interpreted by the system's controller. This session will cover how these sensors
convert physical quantities into readable signals. Mr. Marchese will provide attendees with the
ability to provide their students the necessary information to properly troubleshoot common
sensors used in many applications.
Breaking Through the Technology Barrier in Technical Education
Dr. Chris Molnar, Porter & Chester Institutes
Napa Room D
Learn how to modernize and standardize your curriculum by utilizing tablets, replacing paper
with electronic, and implementing instructional technology in a vocation program while
increasing student involvement, soft skills, and responsibility. The tablet has many more uses
than just an eBook reader or a game machine; this device can make a difference in your
classroom. During this presentation Dr. Molnar will explore a model that can be followed by
others. Upon completion of this session the attendee will have developed a game plan to bring
instructional technology into their HVAC programs and be able to anticipate and navigate some
of the obstacles to success.

Retro-Commissioning for Existing Facilities
Jim Bochat, National Environmental Balancing Bureau
Sonoma Room A
This session will cover building commissioning in general and retro-commissioning in particular.
Discussion points include: what are Cx and RCx, optimization of HVAC systems, optimization of
control systems, electrical system evaluation and improvement, system performance and
operations evaluation, operator instruction and training.
Pressure Enthalpy Simplified
Eugene Silberstein, CMHE, Suffolk County Community College
Sonoma Room B
This session will cover some easy to implement tips that will enable you to introduce pressure
enthalpy in a logical manner that will enhance learning of the basic refrigeration cycle. Starting
with the basic "refrigeration cycle square," we will slightly modify the diagram and then ease
into the pressure enthalpy chart and its components.
