How To Develop Cooling Tower Life Cycle Cost Analysis: Incorporating Part Load Values or IPLV

How To Develop Cooling Tower Life Cycle Cost Analysis: Incorporating Part Load Values or IPLV

Creating a reasonable load profile is essential for calculating and then comparing lifecycle costs of specific cooling towers, including various brands and/or models within a specific brand. To do that we have to estimate the number of hours a cooling tower will operate at …

How to Determine Control Head for a Variable Speed Pumping System

How to Determine Control Head for a Variable Speed Pumping System

To control a variable speed pumping system, we must determine the minimum operational head of the system. Some refer to this value as constant head, minimum head, independent head, etc. Throughout this and in other JMP blogs, we refer to it as ...

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....
