The advantage of ground heat collectors and geothermal baskets is its simpler approval procedure and the lower investment costs compared to borehole heat exchangers. For these type of source systems, however, there is no method for the determination and characterisation of its thermal behaviour in the subsurface, as it is the case for borehole heat exchangers using the thermal response test method. Therefore, in the subproject, a thermal test method for ground heat collectors is developed and tested using a trench collector as an example.
- Development of a test concept
- Design and construction of a modularly expandable test unit for trench collectors with heating and cooling function
- Construction of an experimental plant with trench collector at the Biberach University of Applied Sciences
- Test and validation of the trench collector model and evaluation methodology
