Controller
The controller has the responsibility of ensuring optimal operation of the system. Control
parameters can be set for various components. For storage tanks, for example, target temperatures,
switching temperatures.
Cooled Cooled
Costs
Consumption of goods to create and sell services and other goods.
Daily consumption [l]
The average daily domestic hot water consumption. This is usually 35-45 liters per person and day at
a water temperature of 50°.
Declared value for thermal conductivity λ [W/(mK)]
Value of the → thermal conductivity of a construction material or product under specific external and
internal conditions which can be considered typical of the behavior of this product when installed in
a component.
Default data Def.
Design temperature °C
Temperature determined by the relevant climate zone as per DIN EN 12831 supplement 1 table 1a. The
design temperature is the maximum (necessary) temperature of the heating water which suffices at
the lowest winter temperature for the heating system to provide the building with required amounts
of heat.
Deverter / injection system
Special version of a control circuit. Particularly useful when the user is far away from the output but if
required needs hot water promptly (often RLT)
DHW consumption DHW con
DHW requirement
→ Daily consumption
DHW requirement, specific, qT
The heat, based on the floor space, that must be provided for heating domestic hot water. The
guideline value from the EnEV is 12.50 kWh/m²a.
Diffuse radiation Gdiff [W/m²]
Part of solar irradiation which strikes a horizontal or tilted surface via scattering through air
molecules and mist particles or reflection on clouds.
DIN V 18599
"Energy efficiency of buildings, calculation of net, final, and primary energy requirements for
heating, cooling, ventilation, domestic hot water, and lighting" Basis of calculation for the EnEV
2009 certifications for residential and non-residential buildings
Direct radiation Gdir [W/m²]
Part of solar irradiation which strikes a horizontal or tilted surface without changing direction.
