Congratulations. You have passed the test and completed the 97 - Pumping schemes in chilled water systems
Achieved badges:
Q: Why is the constant primary circulation system no longer used?
A: The parts are no longer available
Q: Why is the constant primary circulation system no longer used?
A: It's too noisy
Q: Why is the constant primary circulation system no longer used?
A: It's not very energy-efficient
Q: What do condensor pumps do?
A: They dissipate heat from chiller compressor coils to the atmosphere
Q: What do condensor pumps do?
A: They distribute chilled water to the conditioned space.
Q: What do condensor pumps do?
A: There is no such thing as a condenser pumps
Q: Why is low Delta T a serious problem for a typical pumping scheme?
A: It results in heavy wear and tear of the valves
Q: Why is low Delta T a serious problem for a typical pumping scheme?
A: It reduces the installed chiller capacity at the plant
Q: Why is low Delta T a serious problem for a typical pumping scheme?
A: It causes the system to break down, because of a safety measure
Q: What happens to the return air temperature when the heat load at the end of the day decreases?
A: The return air temperature increases
Q: What happens to the return air temperature when the heat load at the end of the day decreases?
A: The return air temperature also decreases
Q: What happens to the return air temperature when the heat load at the end of the day decreases?
A: The return air temperature remains the same, but the supply temperature increases.
