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…

Cooling Tower Suction Piping Guidelines

When designing cooling tower suction piping, it is absolutely critical that engineers have sufficient NPSH to the condenser water pump and avoid any piping design errors that could cause air to come out of the pumping solution.  If either of these becomes a problem…

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. …
