Main purpose
Knowledge
The student will gain knowledge about geothermal systems as a sustainable energy source and to obtain an understanding of the physical design, dimensions, functions and operation of these systems.
Skills
After the completion of the course, the student must be able to:
• Describe the thermal properties of rock and soil.
• Explain the working principle of a heat pump.
• Calculate thermal conductivity from thermal response test data.
• Dimension a geothermal system using the professional software EED.
• Calculate COP for a heat pump by measuring produced and spent energy in a system.
• Describe the construction of a borehole heat exchanger and identify critical areas.
• Identify the various conflicts of interest in relation to ground source heating and cooling.
