Test results
Congratulations. You have passed the test and completed the 69 - The Grundfos Distributed Pumping Course
Achieved badges:
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 redundant
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: How much flow is required to achieve almost 80 % of the capacity?
A: 50%
Q: How much flow is required to achieve almost 80 % of the capacity?
A: 30%
Q: How much flow is required to achieve almost 80 % of the capacity?
A: 80%
Q: How does distributed pumping ensure minimum flow over each chiller?
A: By having a differential pressure sensor installed across each chiller
Q: How does distributed pumping ensure minimum flow over each chiller?
A: By running with maximum flow at maximum load
Q: How does distributed pumping ensure minimum flow over each chiller?
A: By ensuring the primary pump is larger than in a conventional system
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: How does the MPC controller protect chillers from freezing?
A: By fulfilling the chiller setpoint signal
Q: How does the MPC controller protect chillers from freezing?
A: By ensuring minimum flow over the active chille
Q: How does the MPC controller protect chillers from freezing?
A: By chiller temperature signal
