Test results
Congratulations. You have passed the test and completed the 48 - Heating systems in commercial buildings
Achieved badges:
Q: Which of the following statements is correct?
A: For flue gas to condensate, the return temperature must be as high as possible
Q: Which of the following statements is correct?
A: For flue gas to condensate, the return temperature must be as low as possible
Q: Which of the following statements is correct?
A: The more efficiently a system operates, the more gas is required
Q: What is the main reason for a heating system being out of balance?
A: Owners buy pumps that are oversized
Q: What is the main reason for a heating system being out of balance?
A: The new pump can’t work with the old pump
Q: What is the main reason for a heating system being out of balance?
A: Commissioning of heating systems is generally poorly done
Q: What can happen if systems and zones are poorly balanced?
A: This may result in too high Delta T, which means you pay too much for energy
Q: What can happen if systems and zones are poorly balanced?
A: Nothing to worry about, if the extra energy costs don’t bother you
Q: What can happen if systems and zones are poorly balanced?
A: This may result in decreased Delta T and lower end-user comfort
Q: What happens if a heating system is imbalanced?
A: Operating costs are increased
Q: What happens if a heating system is imbalanced?
A: The building will be too hot
Q: What happens if a heating system is imbalanced?
A: The pump will vibrate excessively
Q: What is Grundfos FLOWLIMIT?
A: An electronic flow commissioning and limiting functionality built into the pump
Q: What is Grundfos FLOWLIMIT?
A: An external controller that works with the pump
Q: What is Grundfos FLOWLIMIT?
A: A quick commissioning tool that lets you adjust the right pressure and flow from the pump
Q: What is it a correctly balanced system helps with?
A: Keeping return temperatures high
Q: What is it a correctly balanced system helps with?
A: Adapting performance to increase flow
Q: What is it a correctly balanced system helps with?
A: Keeping Delta T at the design flow level
