Flow Tolerance in a System with Variable Speed Pump Control

In our last blog we discussed how to leverage system diversity to maximize energy efficiency. Specifically, we learned that we can size heating or cooling capacity based on peak blog load rather than total connected load if the system is designed and operated correctly. Today, we will talk about flow tolerance and how ...

Hydronic Balancing Part 2: Making the Most of System Diversity

/
Practically any commercial or institutional building has a certain amount of diversity within its cooling load, meaning that peak loads will never occur simultaneously in all sections or zones of a facility. By mapping out the individual load patterns of these sections, engineers can adjust the mechanical design to reduce the overall amount of installed cooling capacity. This means incorporating variable flow, which necessitates precise hydronic balancing.
