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.
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 …
Read MoreIn our last two blogs, we discussed Part Load Efficiency Value (PLEV) from Bell & Gossett. Today we will discuss how using PLEV as the only criteria for selection can lead to HVAC pump selections that aren’t necessarily the best choice...
Read MoreAlthough the DOE’s new pump efficiency standards raise the bar for manufacturers to build more efficient pumps, its rating system should not be looked at as a shortcut to efficient pump selection. Careful consideration of part load efficiencies applied to realistic load profiles is still the only way ...
Read MoreIt should be clear by now that selecting a pump based on design conditions and best efficiency point (BEP) will not yield optimum system efficiency. We’ve also learned that virtually every HVAC pump system will have a minimum amount of pump head, even in the absence of demand. In between these minimum and maximum operating conditions lies the control range for our pump. Keeping all this in mind, how do we select the most efficient pump for a specific application?
