Q: In a cooling system, a large body or surface with a lower temperature than the other surfaces in a room will…
A: …emit more radiation than it receives
Q: In a cooling system, a large body or surface with a lower temperature than the other surfaces in a room will…
A: …emit and receive the same amount of radiation
Q: What characterises hydronic systems for heating or cooling?
A: Lower energy distribution costs and improved space efficiency
Q: What characterises hydronic systems for heating or cooling?
A: No change in energy distribution costs; improved space efficiency
Q: What characterises hydronic systems for heating or cooling?
A: Lower energy distribution costs; no change in space efficiency
Q: Water’s heat capacity is how many times greater than that of air?
A: 2.1
Q: Water’s heat capacity is how many times greater than that of air?
A: 2.4
Q: Water’s heat capacity is how many times greater than that of air?
A: 4.2
Q: How much energy is potentially saved when using a hydronic system instead of an air-based system?
A: Up to 25%
Q: How much energy is potentially saved when using a hydronic system instead of an air-based system?
A: Up to 35%
Q: How much energy is potentially saved when using a hydronic system instead of an air-based system?
A: More than 40%
Q: How much more power does a forced air system use for the distribution of air than a hydronic system?
A: Twice as much power is required by air-based systems
Q: How much more power does a forced air system use for the distribution of air than a hydronic system?
A: Both use the same power; hydronic systems benefit from improved space efficiency only
Q: How much more power does a forced air system use for the distribution of air than a hydronic system?
A: As much as 10 times more power may be required by air-based systems
Q: What does the superior energy capacity of water mean?
A: Hydronic systems are not as good as forced-air systems, because they don’t release energy as readily
Q: What does the superior energy capacity of water mean?
A: Hydronic systems consume much less energy for energy transportation than forced air systems
Q: What does the superior energy capacity of water mean?
A: Water’s high density makes it inefficient for energy distribution in heating or cooling systems
