Buildings.Fluid.SolarCollectors.Data
Data for solar thermal collectors
Information
Package with performance data for solar thermal collectors. All solar collector data package names begin with an abbreviation of the type of collector it is. The abbreviations are as follows:
- C: Concentrating
- FP: Flat Plate
- T: Tubular
Extends from Modelica.Icons.MaterialPropertiesPackage (Icon for package containing property classes).
