modelBuildingRCZ1Valve
One-zone RC building model with distribution pumps and mixing valves
Extends from Buildings.DHC.Loads.BaseClasses.PartialBuilding (Partial class for building model).
Information
This is a simplified one-zone building model based on a one-element reduced order room model. The corresponding heating and cooling loads are computed with a four-pipe fan coil unit model derived from Buildings.DHC.Loads.BaseClasses.PartialTerminalUnit and connected to the room model by means of fluid ports.
The heating and chilled water distribution to the terminal units is modeled with an instance of Buildings.DHC.Loads.BaseClasses.FlowDistribution including a mixing valve to control the supply temperature.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Integer | nPorts_aHeaWat (from PartialBuilding) | 0 | Number of heating water inlet ports |
| Integer | nPorts_bHeaWat (from PartialBuilding) | 0 | Number of heating water outlet ports |
| Integer | nPorts_aChiWat (from PartialBuilding) | 0 | Number of chilled water inlet ports |
| Integer | nPorts_bChiWat (from PartialBuilding) | 0 | Number of chilled water outlet ports |
| Integer | nZon | 1 | Number of thermal zones |
| Configuration | |||
| Boolean | have_heaWat (from PartialBuilding) | false | Set to true if the building has heating water system |
| Boolean | have_chiWat (from PartialBuilding) | false | Set to true if the building has chilled water system |
| Boolean | have_eleHea (from PartialBuilding) | false | Set to true if the building has decentralized electric heating system |
| Boolean | have_eleCoo (from PartialBuilding) | false | Set to true if the building has decentralized electric cooling system |
| Boolean | have_fan (from PartialBuilding) | false | Set to true if fan power is computed |
| Boolean | have_pum (from PartialBuilding) | false | Set to true if pump power is computed |
| Boolean | have_weaBus (from PartialBuilding) | false | Set to true to use a weather bus |
| Boolean | have_heaLoa (from PartialBuilding) | have_heaWat or have_eleHea | Set to true if the building has heating loads |
| Boolean | have_cooLoa (from PartialBuilding) | have_chiWat or have_eleCoo | Set to true if the building has cooling loads |
| Scaling | |||
| Real | facMul (from PartialBuilding) | 1 | Multiplier factor |
