Ferris State University

Douglas F. Zentz, Associate Professor, from the HVACR Programs within the College of Engineering Technology at Ferris State University received his Bachelor’s degree in Mechanical Engineering Technology from Purdue University in 1980 and Master degree in Career and Technical Education from Ferris State University in 2007. He is a past President of West Michigan ASHRAE, a past RVC for Region V, and past Chair for Student Activities within ASHRAE. Doug received the Distinguished Service Award from ASHRAE in 2015, a Distinguished ASHRAE Lecturer and is the RMCR for Region V.

In the field of HVACR, his background includes professional engineering sales for the Trane Company, manager of engineering-design-build for W.J. O’Neil Company in Detroit, and vice-president of engineering for EPPA-Strand Custom Air Handling in Detroit. This experience started in 1980 and continued until his transformation into teaching at Ferris State University in 2003.

In the area of teaching, he has taught junior and senior level HVAC Design (primary and secondary systems), Primary Equipment Selection, Commercial Building Heat Gain/ Heat and the senior Capstone Experience. His teaching experiences includes development of new curriculum (both in the traditional classroom and fully on-line) and teaching fully on-line courses for over 15 years. He has mentored eight (8) different student groups which have received either a First, Second, or Third place recognition from ASHRAE in the Student Design Competition. He serves on many educational committees and was a member of Fluke Instrument’s Advisory Board on IAQ.

In the area of professional speaking, he has been the guest speaker at over 60 events since 2005. Organizations which have invited him to speak include: 1) Mechanical Contractors of America, 2) Air Conditioning Contractors of America, 3) ASHRAE 4) ARI (teachers workshop), 5) Lily West Conference (educational workshop), 6) USGBC (West Michigan), 7) Ferris State University (Energy Conferences), and 8) Efficiency United (educational arm of 16 Michigan Utilities).

Dinner Presentation Topic

Applied Psychrometrics

This presentation will include the following elements; (a) a review of the Psychrometric processes, (b) defining state points of saturated air and how this creates the basis of the Psychrometric Chart, (c) the application of mixed air streams, (d) defining sensible heat ratio and applying this to the Psychrometric Chart, and (e) illustrating real world examples of HVAC systems to the Psychrometric Chart. The examples illustrated will include a common heating and ventilation unit with humidification, a 100% outside air unit used in process cooling applications where supply air temperature and absolute humidity are critical, a common VAV air handling unit with mixed return/outside air which must supply cooled air to satisfy a specific space Sensible Heat Ratio, and a more complex Dual Duct system where final supply air out of a diffuser can be calculated/illustrated through Psychrometrics (this example illustrates problem solving and integrates heat transfer equations of fluids).
