recordFourPortResistanceChillerWSE
Flow resistance model for the chiller and WSE package
Information
This class contains parameters that are used to compute the pressure drop in the Buildings.Applications.DataCenters.ChillerCooled package.Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Flow resistance › Medium 1 | |||
| Boolean | computeFlowResistance1 | true | =true, compute flow resistance. Set to false to assume no friction |
| Boolean | from_dp1 | false | = true, use m_flow = f(dp) else dp = f(m_flow) |
| Boolean | linearizeFlowResistance1 | false | = true, use linear relation between m_flow and dp for any flow rate |
| Real | deltaM1 | 0.1 | Fraction of nominal flow rate where flow transitions to laminar |
| Chiller | |||
| Modelica.Units.SI.PressureDifference | dp1_chi_nominal | Pressure difference on medium 1 side in the chillers | |
| Modelica.Units.SI.PressureDifference | dp2_chi_nominal | Pressure difference on medium 2 side in the chillers | |
| Waterside economizer | |||
| Modelica.Units.SI.PressureDifference | dp1_wse_nominal | Pressure difference on medium 1 side in the waterside economizer | |

| Flow resistance › Medium 2 | |||
| Boolean | computeFlowResistance2 | true | =true, compute flow resistance. Set to false to assume no friction |
| Boolean | from_dp2 | false | = true, use m_flow = f(dp) else dp = f(m_flow) |
