Speaker Biography:
Charles Jelen is an Application Engineer based out of La Crosse, WI. He is primarily responsible for pre-sale
support of Trane Systems and System Concepts. His areas of expertise are in Chilled Water
Systems, Refrigerants, and System Modeling. Charles has been with Trane for 8 years and has held roles
as TRACE 700 Product Manager, Centrifugal and Water-Cooled Product Support Engineer, and CDS
(Customer Direct Service) Support Engineer. Prior to joining Trane Charles worked as a sales engineer
for a process automation company out of Minneapolis, MN. He is currently involved with ASHRAE at the

from the University of Minnesota, and he lives with his family in La Crosse, WI.

This presentation will provide a system level overview of Sensible Cooling Terminal units, Dedicated
Outside Air units, and the potential chiller plant configurations that feed those components. As
buildings are designed for lower energy use, the resulting reduction in cooling loads presents an
economically feasible opportunity for systems that use zone-level, sensible-only cooling equipment.
These systems combine a dedicated outdoor air system with chilled-water, sensible-cooling terminals to
deliver a flexible, energy efficient solution to provide comfortable spaces and simplify maintenance.
