Correct
Q: What is the key design element in Grundfos Distributed Pumping?
A: The use of intelligent pumps instead of valves
Correct
Q: How much flow is required to achieve almost 80 % of the capacity?
A: 50%
Correct
Q: Pump energy savings in a distributed pumping system are around:
A: 54%
Correct
Q: What is the benefit of aligning primary side flow with secondary side flow?
A: To avoid or minimise the ‘low’ Delta T syndrome
Correct
Q: How does distributed pumping ensure minimum flow over each chiller?
A: By having a differential pressure sensor installed across each chiller
Correct
Q: Why is there in most cases no bypass flow with a distributed pumping system?
A: Because primary pumps try to match primary flow and secondary flow
