UA correction factors for Merkel cooling towers
Extends from Modelica.Icons.Record (Icon for records).
Information
This data record specifies parameters for the flow and temperature correction of the convective heat transfer coefficients used in the model Buildings.Fluid.HeatExchangers.CoolingTowers.DryCooler.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Real | n_w | 0.85 | Water-side exponent for convective heat transfer coefficient, h~m_flow^n |
| Real | n_a | 0.8 | Air-side exponent for convective heat transfer coefficient, h~m_flow^n |
| General › Nominal condition | |||
| Real | r_nominal | 0.5 | Ratio between air-side and water-side convective heat transfer coefficient |
| Advanced › Modeling detail | |||
| Boolean | waterSideFlowDependent | true | Set to false to make water-side hA independent of mass flow rate |
| Boolean | airSideFlowDependent | true | Set to false to make air-side hA independent of mass flow rate |
| Boolean | waterSideTemperatureDependent | true | Set to false to make water-side hA independent of temperature |
| Boolean | airSideTemperatureDependent | true | Set to false to make air-side hA independent of temperature |
