Mr. Creep and the Undermining of Variable Speed Curve Control

Mr. Creep and the Undermining of Variable Speed Curve Control

We call him Mr. Creep.

Mr. Creep is not an actual person but rather a phenomenon of an ever-increasing control head in a variable speed pumping system caused by frequent incidents of underflowing coils, the result of which is progressive increases in operating cost and potential non-compliance....

Flow Tolerance in a System with Variable Speed Pump Control

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 ...
