By having a differential pressure sensor installed across each chiller
1: How does distributed pumping ensure minimum flow over each chiller?
By running with maximum flow at maximum load
You can find the answer here >
1: How does distributed pumping ensure minimum flow over each chiller?
By ensuring the primary pump is larger than in a conventional system
You can find the answer here >
2: What is the key design element in Grundfos Distributed Pumping?
A new kind of intelligent valve
You can find the answer here >
2: What is the key design element in Grundfos Distributed Pumping?
The use of intelligent pumps instead of valves
2: What is the key design element in Grundfos Distributed Pumping?
Making bypass lines obsolete
You can find the answer here >
3: Why is there in most cases no bypass flow with a distributed pumping system?
Because primary pumps try to match primary flow and secondary flow
3: Why is there in most cases no bypass flow with a distributed pumping system?
The bypass valve is always closed
You can find the answer here >
3: Why is there in most cases no bypass flow with a distributed pumping system?
The system is never over-pumped
You can find the answer here >
4: Why is coil flow always correct in a distributed pumping system?
By using large variable speed-controlled primary pumps
You can find the answer here >
4: Why is coil flow always correct in a distributed pumping system?
Because Magna 3 pump speed is modulated based on terminal unit load
