Meeting Title: Spring YEA and Student Activities Learning Seminar
Meeting Details:

Spring YEA and Student Activities Learning Seminar

Meeting Location: The Barrel House, 10AM - 11:15AM.

For the February 8, 2017 chapter meeting, the Bluegrass Chapter will be hosting Distinguished Lecturer Doug Zentz. As part of his visit and before the regular Chapter meeting, Doug will lead an additional learning opportunity for the chapter and will present a 1.5 hour seminar on applied psychometrics.

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 Psychometrics (this example illustrates problem solving and integrates heat transfer equations of fluids).

This a great opportunity to receive a professional presentation of the topic as a refresher for an experienced engineer or practical introduction for younger engineers and students.

Cost for the seminar will be:


  • $40 for current ASHRAE members for both the Seminar and the regular lunch meeting and $35 for the seminar only. Note, by registering and attending both the seminar and lunch current members can save $5.
  • $50 for non-members. If a non-member joins or commits to join ASHRAE at the meeting they will get complementary admission to the seminar.
  • Students are free.


Pastries, coffee, and soft drinks will be provided.
