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: 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
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 benefit of aligning primary side flow with secondary side flow?
A: To ensure distributed pumps never miss water on the suction side
Q: What is the benefit of aligning primary side flow with secondary side flow?
A: To avoid increasing pressure in the bypass pipe
Q: What is the benefit of aligning primary side flow with secondary side flow?
A: To avoid or minimise the ‘low’ Delta T syndrome
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
