Correct
Q: What influence does the introduction of radiant cooling systems have on other building services?
A: Air volumes, air handlers and air ducts can be reduced in size because radiant cooling systems take care of the sensible heat loads and a dedicated outdoor air systems can be introduced (DOAS).
Correct
Q: The heat energy distribution costs of hydronic systems are about 1/10 of the cost of a forced air system. How come?
A: Because forced air systems need much more air volumes to transport the same amount of energy than is the case with water.
Correct
Q: How does radiant cooling in a room work?
A: A radiant ceiling or floor is a low temperature surface, which receives more heat radiation than it emits and thereby removes sensible heat loads. A radiant ceiling also absorbs heat by convection.
Correct
Q: When is zoning an advantage?
A: When a building has different requirements to temperature or when the internal load from occupants is different.
Correct
Q: Because the fan pressure needed in air handlers are much greater than the pressure needed in water based hydronic systems.
A: Because forced air systems need much more air volumes to transport the same amount of energy than is the case with water.
Correct
Q: Hydronic systems take up much less space than forced air systems in a building. Why is that?
A: Because hydronic systems use water as the cooling media, and water can carry more energy than air. That means smaller systems are needed to transport the same amount of energy.
