[TRNSYS-users] Two boreholes and one heat pump installation

[Matthieu Saint-Ellier (215419)]

Dear TRNSYS users and support team,

I am dealing with a project containing a water-water heat pump and two U-tubes boreholes (Vertical ground heat exchangers).

The objective of this project is to extract energy from one of the borehole and try to store it in the other one thanks to the heat pump in order to use this energy in cold season for instance.

I would like to simulate this installation in an easy way on TRNSYS software.

In the first place, my problem is that on TRNSYS you can only have one borehole (Vertical ground heat exchanger) per project. However, in my model I would need two of these.
Therefore, I would like to know if there is any way to solve this problem or otherwise, which components of the TRNSYS library could be used to simulate the storage of energy in a borehole.

In the second place, the refrigerant of the heat pump I use is the 407C. But is seems that the attached file WWHP_Heating-Normalized.dat located in .\Tess Models\SampleCatalogData\Water-to-WaterHeatPump\Normalized only contains datas about the R134a refrigerant. I woud like to know how we can deal with other refrigerant.


Thank you very much.

Regards.
