This class is targeted at mechanical engineers and goes over design practices and choices the engineer can make that will improve energy efficiency well over the current ASHRAE minimum targets. The class materials will take 60 – 75 minutes to present, and a six question quiz at the end will be administered to verify the content was understood. Learning Objectives At the successful conclusion of this course, you’ll be able to identify and discuss:

• Review the difference in part load operation between centrifugal and screw chillers, and when to use one over the other.
• Explain how condenser water temperature (and flows) impacts screw and centrifugal operation and efficiency.
• Explain how chillers in a series-counterflow arrangement can provide savings over chillers in standard parallel arrangement.
• Review why screw chillers are a viable option for series-counterflow, and centrifugals are typically not.
