We are using VFDs to control the pumps speed to match the flow requirements for varying load conditions in the building. In addition, 3 port bypass valves are installed at the index point to maintain cooling demand. Would Belimo controls be of use here in this design since the flow is already controlled using drives?
Technically both, but the video addresses the issue where the intent was for a building or coil to achieve a higher delta T (i.e. temperature rise across the building/coil), but the actual performance is less. The intent would be to match the desired condition at your chiller plant..

Is delta T calculated from the supply and return temperature of buldings or the chiller set point to return ???
