Test results
Congratulations. You have passed the test and completed the 48 - Heating systems in commercial buildings
Achieved badges:
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
Q: What does an intelligent circulator pump from Grundfos offer?
A: A built-in sensor that controls throttling valves
Q: What does an intelligent circulator pump from Grundfos offer?
A: Flow-limiting functionality that makes pump throttling valves redundant
Q: What does an intelligent circulator pump from Grundfos offer?
A: A built-in throttling valve, enabling greater precision control
Q: What is the efficiency increase achieved if FLOWLIMIT is enabled in an intelligent circulator pump?
A: 10%
Q: What is the efficiency increase achieved if FLOWLIMIT is enabled in an intelligent circulator pump?
A: Less than 10%
Q: What is the efficiency increase achieved if FLOWLIMIT is enabled in an intelligent circulator pump?
A: The primary benefit is improved occupant comfort, not system efficiency
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 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 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
