modelFlatPlateNPanels
Validation model for flat plate collector with different settings for nPanel
Extends from Buildings.Fluid.SolarCollectors.Validation.FlatPlate (Validation model for FlatPlate).
Information
This model validates the solar collector model
Buildings.Fluid.SolarCollectors.ASHRAE93
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.
