ground heat exchanger double-u boreholes
Can I simulate a geothermal field with double-u boreholes in OpenStudio, without use of GLHEPro? I alredy know the proprieties of the ground and the borehole (tube and grout) and also the g-function of the field.
If I put this values in OS:GroundHeatExchanger:Vertical and I run the simulation, it give me this error: Severe ** Plant temperatures are getting far too cold, check controls and relative loads and capacities.
This is the condenser loop. On the right, you can see some parameters of the borehole; others values are:
Pipe out diameter: 0.032 m;
U-tube distance: 0.0505 m;
Pipe thickness: 0.003 m.
I used a "setpoint manager schedule" on the outlet node of the supply side that imposes a temperature of 6°C.
Also, you can see here the output error:
Please tag each question with the software you are using, e.g., 'openstudio' and 'glhepro' in this case.
Sounds like you have the ground loop running continuously or have the setpoint controls wrong. Could you update your question to describe the controls you are using and a screenshot of the loop(s) involved?
