Modelling a GSHP coupled with ground water open loop

Hi @MingboPeng,

I would like to model a Ground Source heatpump coupled with a ground water open loop using Ironbug.
In the link below they talk about the PlantComponent:TemperatureSource.
Is it difficult to use this plant component in combination with Ironbug?

Hi @Erikbeeren
I have never modeled with PlantComponent:TemperatureSource for the open water loop.
OpenStudio has this object already: https://openstudio-sdk-documentation.s3.amazonaws.com/cpp/OpenStudio-3.0.0-doc/model/html/classopenstudio_1_1model_1_1_plant_component_temperature_source.html

It should be easy to add it to Ironbug, but not sure how to model this open water loop correctly.
Let me look into some documents, will keep you updated.

Hi @MingboPeng,
Here is the input output reference from energyplus:

It would be nice if the source temperature could be scheduled.

Hi @Erikbeeren the “ScheduleFile” has been added in newest Ironbug for loading hourly csv files

Hi @Erikbeeren

Here is the updated Ironbug with PlantComponent.

I think it should work like this, but haven’t really tested. Please let me know if it works for you.

Hi @MingboPeng,

Thanks for the work, I will let you know if it works.

Only one other problem: When I installed this new ironbug release, the intersect mass component disappeared.
