How To Size A Waterside Economizer Part 1: How ASHRAE 90.1 Updates Have (Or WILL) Change Chilled Water Design

Has your state adopted ASHRAE 90.1-2010 or beyond into its commercial building code? If so, then it is highly likely that you should be incorporating either waterside or airside economizing into your cooling design. The Standard has effectively made air or waterside economizing a requirement in virtually every…

How To Develop Cooling Tower Life Cycle Cost Analysis: Defining Dry Bulb, Wet Bulb, and Approach

In our last blog we suggested incorporating IPLV (Integrated Part Load Values) into your cooling tower lifecycle cost analysis. Next, we need to fill in wet bulb temperatures that correspond with the part load conditions we’ve identified and already added to our lifecycle worksheet. …

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 Develop Cooling Tower Life Cycle Cost Analysis:  Filling In The Blanks

It is important that engineers be able to compare cooling towers (brands and configurations) in terms of both equipment and life cycle cost.  Just as important, that comparison needs to be based on realistic operating parameters.  At JMP we’ve developed a method that lets engineers…
