Code

SE-STS1

Version

2.0

Offered by

Supply Engineering

ECTS

5

Prerequisites

For exchange/transfer students:
General admission requirements and basic understanding of heating systems, heat pumps and energy.

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.

 • Measure heat conductance and heat capacity in soil samples.

 • Explain the working principle of a heat pump.

 • Calculate heat capacity from thermal response test data.

 • Calculate head loss in a pipe system with refrigerant.

 • 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 advantages and disadvantages of various drilling methods.

 • 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.

 • Describe the principal counts in legislation and standards for geothermal systems.

 • Explain the main principles of function and quality control.
