Existing chilled water systems provide the capability to cool buildings efficiently. Yet there are often ways that these existing systems can be upgraded and improved to increase efficiency, better serve building occupants and use existing infrastructure to keep projects cost effective.

This presentation:

  • Discusses chiller retrofits and replacement
  • Explores different design parameters (flow rates and temperatures) and the opportunities they offer existing systems
  • Examines use of variable flow in existing systems
  • Considers controls to optimize and reduce system energy use

Recommended audience: Facilities managers, consulting engineers, contractors, and students.

Mistakes lead to “experience” – that is, knowing what you never want to have happen to you again. It’s a lot less painful to learn from other people’s “experience.”

This seminar, originally presented at an ASHRAE annual conference, covers common chilled water system mistakes; and more importantly how to avoid or mitigate them. Chilled water systems covered include new, retrofit, conversion/addition, and replacement. In addition, control options are also discussed.

Whether novice or experienced, come shake your head, laugh a bit, and learn together.

Recommended audience: Students, consulting engineers, contractors, facilities managers, and anybody else who wants to learn from others’ mistakes!
