EmissionOnOff¶
Variant onoff: on below the set point minus half the band, off above it plus half the band
FastSmoothBuildings.Controls.EmissionOnOff, model (source)
Extends PartialEmissionControl.
Purpose
Emission control of a zone, trano's variant onoff: on when the zone falls below its scheduled set point
minus half the band, off when it rises above the set point plus half the band. The switch is a
Hysteresis, a bistable state, so the thermostat
has no event. It behaves as the OnOffController of the Modelica Standard Library with its
bandwidth.
Equations
y = onOff.y, the hysteresis of u = TSet −
TZon with uLow = −bandwidth/2 and uHigh =
bandwidth/2.
Parameters
bandwidth = 0.1 K. The hysteresis keeps its defaults, onOff.tau = 10 s and
onOff.dU = bandwidth/10; a modifier can lengthen and widen them for a calibration.
Use
Switches the ideal heater of the west room of Examples.TwoZones.
Parameters¶
| Parameter | Type | Unit | Default | Description |
|---|---|---|---|---|
| bandwidth | Real | K | 0.1 | Band of the on/off controller (Modelica OnOffController) |
