Correct
Q: In a cooling system, a large body or surface with a lower temperature than the other surfaces in a room will…
A: …receive more radiation than it emits
Correct
Q: What does the superior energy capacity of water mean?
A: Hydronic systems consume much less energy for energy transportation than forced air systems
Correct
Q: How much energy is potentially saved when using a hydronic system instead of an air-based system?
A: Up to 35%
Correct
Q: What characterises forced-air systems for heating or cooling?
A: They depend on high air volumes for energy transport, often at high air velocities
Correct
Q: When using a hydronic system instead of an air-based system, how much extra floor space might the building owner get from space efficiency gains?
A: Can be as high as 5%, because of the significantly improved space performance
Correct
Q: Water’s heat capacity is how many times greater than that of air?
A: 4.2
