Test results
Congratulations. You have passed the test and completed the 8 - Water boosting in commercial buildings
Achieved badges:
Q: What is a zone divided booster system?
A: The supply system is split into several zones, each with its own booster set
Q: What is a zone divided booster system?
A: A zone divided system is defined by only using in-line pumps
Q: What is a zone divided booster system?
A: You always have a spare pump in case of failure
Q: What is the purpose of pressure relief valves?
A: They reduce the pressure on the lower floors in single booster systems
Q: What is the purpose of pressure relief valves?
A: They reduce the pressure from the city mains at the entrance of the building
Q: What is the purpose of pressure relief valves?
A: They are used in high-rise buildings of more than 20 stories to reduce pressure on the top floors
Q: What are the benefits of an IE4 motor?
A: Fitted with a frequency drive the motor can adjust its speed to demand to lower energy consumption and wear
Q: What are the benefits of an IE4 motor?
A: The motor has all-magnetic bearings
Q: What are the benefits of an IE4 motor?
A: The motor has a built-in delta P sensor
Q: What is the benefit of a booster pump with variable speed
A: The pump automatically adjusts to changes in the water consumption to keep energy usage as low as possible
Q: What is the benefit of a booster pump with variable speed
A: A pump with variable speed is less noisy
Q: What is the benefit of a booster pump with variable speed
A: You can easily increase pressure in case of sediment build-up in pipes
Q: Does a zone divided system require pressure relief valves?
A: No
Q: Does a zone divided system require pressure relief valves?
A: Yes, if the pressure from the main exceeds 10 bar
Q: Does a zone divided system require pressure relief valves?
A: Yes, they will serve as a safety valve in case of pump failure
Q: How is it possible to make sure that an entire system performs at the best efficiency point at all times?
A: An intelligent controller
Q: How is it possible to make sure that an entire system performs at the best efficiency point at all times?
A: Correctly sized pipes
Q: How is it possible to make sure that an entire system performs at the best efficiency point at all times?
A: The right number of pumps
