ASHRAE ST-16-015 - Improving Variable-Speed Pumping Control to Maximize Savings
January 1, 2016 - ASHRAE

According to some estimates, pumps account for between 10% and 20% of world electricity consumption (EERE 2001; Grundfos 2011). Unfortunately, about two-thirds of all pumps use up to 60% too much energy (Grundfos 2011), primarily because of inefficient flow control. Varying pump speed using...
