modelEN12975NPanels
Validation model for collector according to EN12975 with different settings for nPanel
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 the number of panels is 1 for the instance solCol
and 10 for the instance solCol1.
The instances difHeaGai and difHeaLos
compare the heat gain and heat loss between the two models.
The output of these blocks should be zero, except for rounding errors.
