JMP is excited to announce our new technical HVAC magazine! It is a great resource to get bite-sized educational pieces similar to the content featured in our seminars. Register to have the latest blog sent to your email address.
In our previous blog we explained the physics behind that noisy, destructive phenomenon known as cavitation – the result of too little NPSH at the suction of the pump. Today we’re going to dig a little deeper into…
Read MoreAnyone involved in the design or application of fluid pumping systems is familiar with NPSH or Net Positive Suction Head. We typically equate NPSH with one singular question: Is there enough…
Read MoreWhen 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…
Read MoreSo far in this series, you’ve learned how to incorporate all of the essential data into your cooling tower life cycle analysis -- everything from operational hours at part load conditions to suggested outdoor wet bulb design points. You’ve done most of the heavy lifting. Now it is up to the vendor to…
Read MoreIn 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. …
