Abstract: There are several types of HVAC water systems that are designed with diversity, it could be a chilled water system, heat pump loop water system, heating water system or most commonly a reheat water system. When diversity exists in an HVAC water system, the testing, adjusting, and balancing (TAB) of this system requires a system review and careful consideration of the approach to the TAB process. This presentation examines the appropriate TAB approaches to HVAC water system diversity and various testing scenarios.
