Availability Manager Night Cycle Zone list Name

asked 2018-10-31 16:29:22 -0600

updated 2018-10-31 16:30:15 -0600

I have an airloop system connected to 3 zones. I am implementing a Night Cycle, but I want to specify CycleOnControlZone.

When you set the Use Night Cycle option to Cycle on Full System if Heating or Cooling Required, Openstudio will create a 4 OS:ModelObjectList. I think they are created as placeholders as they need to be populated for the forward translator (I have tried leaving all of them blank when using the CycleOnAny option).

How can I specify a single zone for CycleOnControlZone inside Openstudio? The dropdown only refers to the OS:ModelObjectList and all of the OS:ModelObjectList do not refer to anything or are referred by anything else in the .OSM file.

I went to the SDK documentation to find more info about the class. From my understanding, the ModelObjectList object can contain Model class objects. However, it does not look like I can access the vector from the GUI or modify it.

When you export as an .idf you get the list of all of the zones connected to the system. I want to be able to modify this list from the Openstudio GUI.

Quoting the SDK doc for 3.0.1 (but this was the same since 2.3.1)

You can set these by passing a vector of zones:

bool    setControlThermalZones (const std::vector< ThermalZone > &thermalZones)
bool    setCoolingControlThermalZones (const std::vector< ThermalZone > &thermalZones)
bool    setHeatingControlThermalZones (const std::vector< ThermalZone > &thermalZones)
bool    setHeatingZoneFansOnlyThermalZones (const std::vector< ThermalZone > &thermalZones)

and you can reset/clear them:

void    resetControlThermalZones ()    
void    resetCoolingControlThermalZones ()
void    resetHeatingControlThermalZones ()
void    resetHeatingZoneFansOnlyThermalZones ()

These are NOT exposed to the openstudiocoalition/OpenStudioApplication though, you must use the bindings to populate them, or they will be defaulted to ALL zones served by the AirLoopHVAC during ForwardTranslation: You can follow the (quite extensive) logic implemented in ForwardTranslateAvailabilityManagerNightCycle.cpp#L128-L450

Oh, this is from long before I understood the SDK, thanks for replying to this! For me, it is a great feeling to look back and see how much I've learned and a lot of it with your help.
