Heating
What forms of supply(heating) are used on your project?
On a drainage and sewage drawing, how do you indicate a sand trap/collector well?
With a SFB
What does the abbreviation LAR stand for?
Local drainage of rainwater
What does the heat capacity show/indicate?
The building's heat accumulation capacity corresponding to the heat that is stored and released during a diurnal fluctuation.
What is the difference between direct and indirect district heating?
Direct - no exchanger - District heating water directly in the pipes.
Indirect - Plate exchangers between the district heating network and the heating system.
What is RB's well function?
RB is Cleaning well and are used for cleaning the pipes if necessary
Name two techniques that are often used in LAR systems.
Permeable pavements and rain beds.
(and fascines)
Hvilke skygge kategorier findes der i be18?
What shade categories are there in be18?
Where does it make the most sense to install calorifere?
The tool shop
What elevations should we have on a sand trap well?
Cover/terrain level
Inlet level
Outlet level
Water level
Bottom level
How do green roofs contribute to LAR?
Green roofs absorb and delay rainwater
Where does the internal heat supply come from?
From people, appliances, machines and lighting.
When are safety factors used in radiator sizing?
For flashings/cover, different mounts(pipe) and not typical sizes.
According to C213, what do PBS and PBR stand for?
PBS: Pump well - Wastewater
PBR: Pump well - Rainwater
What does a fascine consist of and what is its function?
The fascine typically consists of an underground structure filled with stones or plastic modules, which creates a cavity where rainwater can collect and slowly seep into the surrounding soil.
How can we reduce our transmission losses?
By having better u-values and less line loss.
What dimensioning parameters are required to dimension radiators/floor heating/heaters?
The temperature set and heat loss (which is obtained from be18 transmission)
What is the difference between the assumed and dimensioned water flow?
The assumed water flow is the estimated consumption based on experience etc.
The dimensioning is the water flow we design and dimension the pipes from the outside.
What does K-value mean when talking about sizing fascia?
The hydraulic conductivity of the soil (the speed of water seepage into the soil)
What is the Ff and G value telling us about the windows?
The Ff value is the Glass Share.
The G value is the solar heat transmittance of the window.
