In order to be able to certify thermal response test (TRT) devices, the limits and capabilities of the TRT test rig developed in the previous project QEWS II, which emulates a real borehole heat exchanger (E-BHE), must be determined. This includes dealing with possible disturbances to which the TRT device is exposed in reality, such as electrical grid fluctuations, power interruptions, heating failures, changes in volume flow or also environmental influences due ot a poor test setup. Furthermore, the variation possibilities concerning the virtual borehole length and the thermal conductivity of the ground need to be extended.
- Extension of the TRT test rig (E-BHE) regarding interference effects on TRT devices
- Determining the limits of the E-BHE
- Carrying out field tests
- Analysis of the influence of the integrated borehole heat exchanger model and the evaluation methodology
- Elaboration of certification rules for TRT devices
