Abstract:

This session will explore the troubleshooting process undertaken during the renovation of an elementary school’s condensing water system, which included the installation of two new water-cooled chillers, a cooling tower, and associated pumps. Despite proper design specifications, both chillers failed to maintain condensing water flow during startup. Through systematic analysis, the root causes of the issues—including sump basin debris restricting pump flow and an undersized cooling tower collection basin discharge—were identified and resolved. Participants will gain insights into diagnostic techniques, the impact of system configurations on performance, and best practices for resolving flow-related challenges in complex HVAC systems.

Learning Objectives:

1. Identify Common Flow Issues in Condensing Water Systems – Understand how system design, component sizing, and installation factors can contribute to water flow restrictions and failures.
2. Analyze System Performance and Diagnose Flow Disruptions – Learn how to use pressure drop measurements, pump curves, and manufacturer specifications to pinpoint performance deficiencies.
3. Evaluate the Impact of Component Sizing on System Operation – Examine how undersized drainage openings and improper flow balancing can affect cooling tower operation and system stability.
4. Enhance Project Efficiency Through Effective Planning and Coordination – Explore best practices for coordinating with controls contractors, selecting the right instruments, and executing pre-demo readings efficiently to support seamless system upgrades.
