Test results
Congratulations. You have passed the test and completed the 69 - The Grundfos Distributed Pumping Course
Achieved badges:
Q: Why is coil flow always correct in a distributed pumping system?
A: By using large variable speed-controlled primary pumps
Q: Why is coil flow always correct in a distributed pumping system?
A: Because Magna 3 pump speed is modulated based on terminal unit load
Q: Why is coil flow always correct in a distributed pumping system?
A: Because the system runs with maximum flow at maximum load
Q: Why must low-pressure non-return valves be installed for each cooling loop with AHU’s?
A: You don’t need non-return valves – intelligent pumps make all valves redundanteed
Q: Why must low-pressure non-return valves be installed for each cooling loop with AHU’s?
A: To avoid backflow in case the AHU unit is out of operation
Q: Why must low-pressure non-return valves be installed for each cooling loop with AHU’s?
A: You only need non-return valves for proportional pressure installations
Q: With a single dedicated pump for each terminal unit, which control mode is used?
A: Proportional pressure
Q: With a single dedicated pump for each terminal unit, which control mode is used?
A: Proportional pressure or constant temperature – doesn’t matter
Q: With a single dedicated pump for each terminal unit, which control mode is used?
A: Constant temperature
Q: What is the key design element in Grundfos Distributed Pumping?
A: A new kind of intelligent valve
Q: What is the key design element in Grundfos Distributed Pumping?
A: The use of intelligent pumps instead of valves
Q: What is the key design element in Grundfos Distributed Pumping?
A: Making bypass lines obsolete
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
Q: Why is there in most cases no bypass flow with a distributed pumping system?
A: The bypass valve is always closed
Q: Why is there in most cases no bypass flow with a distributed pumping system?
A: The system is never over-pumped
Q: With a Distributed Pumping system, does commissioning and balancing
A: Take longer
Q: With a Distributed Pumping system, does commissioning and balancing
A: Become obsolete
Q: With a Distributed Pumping system, does commissioning and balancing
A: Is done quickly and easily
