03.
Q: With a single dedicated pump for each terminal unit, which control mode is used?
A: Proportional pressure
03.
Q: With a single dedicated pump for each terminal unit, which control mode is used?
A: Proportional pressure or constant temperature – doesn’t matter
03.
Q: With a single dedicated pump for each terminal unit, which control mode is used?
A: Constant temperature
04.
Q: Why is coil flow always correct in a distributed pumping system?
A: By using large variable speed-controlled primary pumps
04.
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
04.
Q: Why is coil flow always correct in a distributed pumping system?
A: Because the system runs with maximum flow at maximum load
05.
Q: How does distributed pumping ensure minimum flow over each chiller?
A: By having a differential pressure sensor installed across each chiller
05.
Q: How does distributed pumping ensure minimum flow over each chiller?
A: By running with maximum flow at maximum load
05.
Q: How does distributed pumping ensure minimum flow over each chiller?
A: By ensuring the primary pump is larger than in a conventional system
