blockCaseTemperature
Block to compute the case temperature
Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).
Information
This block computes the case temperature for use in Buildings.Fluid.DataCenterEquipment.Racks.LiquidCooledSinglePhase.ColdPlateR_P.
The relative error of the data fit of the thermal resistance R
can be seen in the parameter relErrR.
