Deep Boreholes in GSHP Systems: Pressure Considerations & Installation Practices
About this course
In such cases, hydrostatic pressures must be considered to ensure successful installation can take place. This course focuses on the necessary calculations along with the recommended installation practices for deep geothermal borehole design and installation.
Who should enroll? Geothermal system designers, but particularly architects and engineers involved in commercial system design. You'll get access to the lecture video, an Excel calculator, and additional resources.
This course was developed by the team at GeoPro, GeoConnections, and Dandelion.
Learning Objectives
- Understand the advantages and disadvantages of deep bore design
- Review current industry trends
- Learn how to calculate and evaluate internal versus external hydrostatic pressures exerted on a system.
- Determine the critical design factor, pipe burst or pipe collapse, and learn steps to avoid issues altogether.
