Hello, I'm studying about horizontal ground exchanger.

I used 'GroundHeatExchanger:HorizontalTrench', can decision numbers of trenches, and space between of them.

I tried to use capillary tube for ground heat exchanger, but it's simulation time take so long time.(about 6 hours)

Then I found another method that 'PipingSystem:Underground' have more detailed inputs than 'GroundHeatExchanger:HorizontalTrench', it function as horizontal trenches.

Even after reading the engineering reference and input output reference, I don't know how to set it up

Could you tell me which parts?

@eoinfwepi based on object names you're using EnergyPlus, but are you using an EnergyPlus interface (OpenStudio, DesignBuilder, etc.)?

EnergyPlus cannot currently size a GSHP field, but it has been requested in this GitHub issue. If you would like to see this as well, give the issue a ๐Ÿ‘. From reading the issue, it appears that there may be some ongoing work in this area but it's not clear what the current status is.
