Buildings.Fluid.Actuators.Valves.Data

Data records for table-based valves

Information

This package contains data for the valve Buildings.Fluid.Actuators.Valves.TwoWayTable.

Extends from Modelica.Icons.MaterialPropertiesPackage (Icon for package containing property classes).

Package Content

Buildings.Fluid.Actuators.Valves.Data.Linear Linear Linear opening curve

Buildings.Fluid.Actuators.Valves.Data.Generic Buildings.Fluid.Actuators.Valves.Data.Generic

Generic record for valve parameters

Information

This is a generic record for the normalized volume flow rates for different valve opening positions. See the documentation of Buildings.Fluid.Actuators.Valves.Data for how to use this record.

Extends from Modelica.Icons.Record (Icon for records).

Parameters

TypeNameDefaultDescription
Realy[:] Valve position, starting with 0 and ending with 1
Realphi[size(y, 1)] Normalized volume flow rates for the positions y

Modelica definition

record Generic "Generic record for valve parameters" extends Modelica.Icons.Record; parameter Real y[:](each min=0, each max=1) "Valve position, starting with 0 and ending with 1"; parameter Real phi[size(y,1)](each min=0, each max=1) "Normalized volume flow rates for the positions y"; end Generic;

Buildings.Fluid.Actuators.Valves.Data.Linear Buildings.Fluid.Actuators.Valves.Data.Linear

Linear opening curve

Information

Linear valve opening characteristics with a normalized leakage flow rate of 0.0001.

Note: This record is only for demonstration, as the implementation in Buildings.Fluid.Actuators.Valves.TwoWayLinear is more efficient.

Extends from Generic (Generic record for valve parameters).

Parameters

TypeNameDefaultDescription
Realy[:]{0,1}Valve position, starting with 0 and ending with 1
Realphi[size(y, 1)]{0.0001,1}Normalized volume flow rates for the positions y

Modelica definition

record Linear = Generic ( y = {0, 1}, phi = {0.0001, 1}) "Linear opening curve";
