Three Types of Curve Control for Variable Speed Pumping Systems

We’ve been talking about variable speed control since September 11, 2017, beginning with this blog ASHRAE 90.1-2010/2013: Impact on Variable Speed Pump Control in Chilled Water Systems. Throughout our coverage of this topic, we have introduced and re-introduced the concepts of “Curve Control” and “Area Control” as variable speed pumping control strategies, each time digging a little bit deeper. Today we are going to take an all-inclusive look at Curve Control, because we feel like the concept is often misunderstood .....

ASHRAE 90.1-2010/2013: Impact on Variable Speed Pump Control in Chilled Water Systems

Today we begin a series of blogs exploring modern variable speed pump control. While we have written about variable speeding pumping in the past, we believe that the increasing presence of variable speed systems, along with the rapid evolution of control options, warrants a comprehensive look at variable speed pump control as a...
