Course description

What makes the Standing Column Well (SCW) different and compelling as a geothermal HVAC solution? Students in this course will investigate a number of SCW design applications, and review the key thermal and hydro-geological bases for good performance.

This course will be delivered in two parts: Lecture during module 1 will provide the background and tools students need to complete an entire design exercise on their own for homework. Module 2 will address all questions from module 1, plus all of the tough but important details that determine the success of standing column well systems in the real world. This is a self-paced course - students are not expected to be 'logged in' at any specific time.

Module 1 - Fundamentals of Standing Column Well Geothermal Systems

TOPICS COVERED: A look at what's unique to these systems as opposed to the more common closed loop approach. What's happening in the well as water is circulated between the building and the ground. A progression from cylindrical steady-state heat transfer to transient quasi-steady state implementation. Measurement of thermal conductivity, diffusivity and relaxation characteristics of the well. A look at a SCW installation: drilling techniques, HVAC Hardware, and controls.

  • Lesson 2: Understanding Well Bore Dynamics (26:56 minutes) Preview
  • Lesson 3: Well Bore Heat Transfer Made Easy (37:10 minutes)
  • Lesson 4: Important Thermal & Geo-Physics Measurements for Well Field Design (55:14 minutes)
  • Lesson 5: SCW Installation Example (20:58 minutes)
  • READING: 'How Ground/Water Source Heat Pumps Work' (.pdf)
Module 2 - Design Your Own Standing Column Well System

Students will use lessons from the first half of the course to complete a standing column well design exercise for homework.

  • Download the ARB Geowell Simulator Excel Spreadsheet (.xlsx)
  • VIDEO SOLUTION: Watch Dr. Koenig solve the homework question using the ARB Geowell Simulator (10:59 minutes)
  • HOMEWORK SOLUTION: Download a PDF of the homework solution (.pdf)
Module 3 - Advanced Standing Column Well Design Training

TOPICS COVERED: Unlike closed loops, open loop systems require extension into the mechanical room for heat exchange...towards a turnkey system. HVAC system performance hinges on EWT to the heat pumps and parasitic power used to transport heat. Addressing the time dependent elements of load, SCW temperature, heat pump operation and parasitic power over extended periods. What's the payback on the net capital outlay? We'll conclude by considering potential regulatory issues.

Conclusion - Feedback and Additional Resources

This is our last module but you still have access to the all of course materials for 12 months (1 year), so keep working and you'll be able to complete the course at your own pace. After your year of access expires you can optionally extend access with a HeatSpring Membership. Enjoy the course and keep in touch!
