Sorry. You did not pass the 69 - The Grundfos Distributed Pumping Course test this time
Achieved badges:
How would you rate this course?
1: 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
1: 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 >
1: Why is there in most cases no bypass flow with a distributed pumping system?
The system is never over-pumped

2: How do variable-speed pumps affect the manual balancing process in HVAC systems?
Variable-speed pumps make the manual balancing process obsolete by automatically balancing the system according to actual demands.
2: How do variable-speed pumps affect the manual balancing process in HVAC systems?
Variable-speed pumps require manual balancing to be performed more frequently to maintain system efficiency.

2: How do variable-speed pumps affect the manual balancing process in HVAC systems?
Variable-speed pumps complicate the manual balancing process, making it more tedious and time-consuming.

3: With a Distributed Pumping system, does commissioning and balancing
Is done quickly and easily
4: How does the MPC controller protect chillers from freezing?
By fulfilling the chiller setpoint signal

4: How does the MPC controller protect chillers from freezing?
By ensuring minimum flow over the active chille
4: How does the MPC controller protect chillers from freezing?
By chiller temperature signal

5: Why must low-pressure non-return valves be installed for each cooling loop with AHU’s?
You don’t need non-return valves – intelligent pumps make all valves redundant
You can find the answer here >
5: Why must low-pressure non-return valves be installed for each cooling loop with AHU’s?
To avoid backflow in case the AHU unit is out of operation
5: Why must low-pressure non-return valves be installed for each cooling loop with AHU’s?
You only need non-return valves for proportional pressure installations
You can find the answer here >
6: With a single dedicated pump for each terminal unit, which control mode is used?
Proportional pressure
You can find the answer here >
6: With a single dedicated pump for each terminal unit, which control mode is used?
Proportional pressure or constant temperature – doesn’t matter
You can find the answer here >
6: With a single dedicated pump for each terminal unit, which control mode is used?
Constant temperature
