modelEN12975_Array
Validation model for collector according to EN12975 in array configuration
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model validates the solar collector model
Buildings.Fluid.SolarCollectors.EN12975
for the case where one model has multiple panels in a 2x2 array,
versus the case where two models are in parallel,
each having two panels in series.
The output of the block dT must be zero,
as both cases must have the same outlet temperatures.
Furthermore, the pressure drops over all models should be the same.
