Data record of nominal values
Extends from Modelica.Icons.Record (Icon for records).
Information
This is the base record of nominal values for air source DX heating coil models.
See the information section of Buildings.Fluid.DXSystems.Heating.AirSource.Data.Generic.DXCoil for a description of the data.
