The Air-Conditioning, Heating, and Refrigeration Institute has introduced two new certification programs for variable frequency drives (VFDs) and datacom cooling (DCOM) equipment.
Take a large hospital, subtract unexamined rules of thumb, add meaningful incremental improvements like VFD’s and a controls upgrade, and what do you get? Smarter engineering via improved performance for both the pumps and the chillers. But it all starts with one little question.
The VARIOspeed® VFD is designed specifically for pressure control applications. As the flow and head conditions change in the pumping system, the VARIOspeed® VFD is able to automatically control the pump speed and maintain a constant discharge pressure.
