7.3.5 Piping
System Definition > Collector Array > Piping
The following information is entered on the Piping page:
Image: Dialog for the piping of the
collector array
The single length of piping and the thermal conductivity coefficient for insulation is subdivided and
entered for inside, outside, and between the collectors. The distinction influences the calculation of
piping losses.
The nominal diameter of the pipes in the solar loop can be directly entered or calculated.
If you select specific, the program calculates the pipe diameter after you have entered the flow velocity.
As the calculation results in inexact values, the program automatically selects the next large DIN nominal
pipe diameter. Manual changes are possible at any time.
The thickness of insulation can be entered exactly or as % of nominal diameter. In this case, the
following insulation thicknesses are available: 20mm, 30mm, 40mm, 50mm, 65mm, 80mm, and 100mm.
For values up to 80mm, the thickness of the insulation is set to the next higher nominal diameter, while a
nominal diameter of 100mm is calculated for values above 80mm. The specific setting of 100% is
recommended, i.e. the thickness of the insulation approximates the nominal diameter.
7.4 Tanks
System Definition > Tank or system schematic
Different types of tanks are loaded depending on the system. The following tank types are included:
• Single coil DHW tank
• Dual coil DHW tank
• Heating buffer tank
• Combination tank (internal heat exchanger or tank in tank)
