Part Load Efficiency Values (PLEV) Part 5: BTUH Load Output vs. Percent of Flow Tolerance

We recently introduced the part load efficiency value (PLEV) aspect of the Bell & Gossett online pump selection tool. PLEV for pumps is based on flow rate while the Integrated Part Load Value (IPLV) for chillers is based on load. This final segment on PLEV will look at the difference.

Let’s begin by examining....

Part Load Efficiency Values (PLEV) Part 2: How to use PLEV for Pump Selection

In our last blog post, we introduced the PLEV, or Part Load Efficiency Value from Bell and Gossett. This week we look at some selections and how to use PLEV.

PLEV was created to give a weighted average of the pump efficiency for the HVAC and plumbing industry. This new efficiency average gives the engineer or designer an efficiency that is most likely a better representation of the actual...
