Test results
Congratulations. You have passed the test and completed the High efficiency hydronic systems
Achieved badges:
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.
Q: Hydronic systems take up much less space than forced air systems in a building. Why is that?
A: Because the water velocity in hydronic systems are higher than the velocity in ducts with air and hence much smaller pipes are used.
Q: Hydronic systems take up much less space than forced air systems in a building. Why is that?
A: Because when using hydronic systems such as chilled ceilings and floors, there is no need for ventilation.
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.
Q: Because the fan pressure needed in air handlers are much greater than the pressure needed in water based hydronic systems.
A: Because the efficiency of pumps are much greater than the efficiency of fans.
Q: Because the fan pressure needed in air handlers are much greater than the pressure needed in water based hydronic systems.
A: Because the fan pressure needed in air handlers are much greater than the pressure needed in water based hydronic systems.
Q: What effect does the introduction of radiant cooling systems have on the chilled water production?
A: With radiant cooling systems it is increasingly feasible to utilise sustainable chilled water sources for free cooling because the chilled water temperature is up to approx. 8 - 10 °C higher than with traditional systems.
Q: What effect does the introduction of radiant cooling systems have on the chilled water production?
A: Radiant cooling systems require more or less the same chilled water temperature as traditional systems, which means the use of sustainable sources are at the same level.
Q: What effect does the introduction of radiant cooling systems have on the chilled water production?
A: Production of chilled water from sustainable sources such as cold ground water or water from rivers and lakes is not feasible due to high initial investment and long distribution pipes.
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.
Q: How does radiant cooling in a room work?
A: A radiant ceiling or floor takes care of sensible and latent heat loads by absorbing heat in form of radiation as well as convection.
Q: How does radiant cooling in a room work?
A: Radiant ceilings or floors works both by radiation and convection and they take care of sensible as well as latent heat loads
Q: When is zoning an advantage?
A: When a building has different requirements to temperature or when the internal load from occupants is different.
Q: When is zoning an advantage?
A: When a building is more than 1000 m2
Q: When is zoning an advantage?
A: When a building has more than three floors
Q: Why is a mixing loop the best way to control a radiant system?
A: Because flow rate and temperature can be adjusted according to the desired performance of the radiant surface
Q: Why is a mixing loop the best way to control a radiant system?
A: Mixing loops allow for constant flow on both the primary and secondary side, which ensures reduced pumping costs
Q: Why is a mixing loop the best way to control a radiant system?
A: Because temperature is quickly and accurately adjusted in the radiant surface
