Validation model for flat plate collector with different settings for nPanel
Diagram of FlatPlateNPanels

Extends from AixLib.Fluid.SolarCollectors.Validation.FlatPlate (Validation model for FlatPlate).

Information

This model validates the solar collector model AixLib.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.
