Chilled Water Systems
Available in both virtual and in-person, instructor-led formats, this Chilled Water Systems seminar will teach you how to keep your system running efficiently, whether it keeps people or equipment cool.
Description
Students will learn about components used in chilled water systems, uses and applications of chilled water systems among many other things. This seminar is perfect for anyone looking to increase their knowledge about chillers, cooling towers and other chilled water systems.
Course Outline
Day One - Discussion Topics
Day One examines the basics of chilled water systems including chillers and cooling towers. We’ll do an overview and review heat theories so students understand why things happen.
