Test results
Congratulations. You have passed the test and completed the Water boosting in commercial buildings
Achieved badges:
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 storeys to reduce pressure on the top floors
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 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: Where are the booster sets in a zone divided system placed?
A: In the basement of the building
Q: Where are the booster sets in a zone divided system placed?
A: Next to the tap at the critical spot
Q: Where are the booster sets in a zone divided system placed?
A: In a pit right in front of the building
Q: What is the purpose of a booster pump?
A: To increase water pressure
Q: What is the purpose of a booster pump?
A: To reduce lime sediments in steel pipes
Q: What is the purpose of a booster pump?
A: To increase water pressure in plate heat exchangers used for hot water production
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
