Advanced thermal response tests: A review
Renewable and Sustainable Energy Reviews, 2020 Abstract In this study, the historical and technical development and the current status of distributed (DTRT) and enhanced (ETRT) thermal response tests (TRT) are reviewed. The different test setups of these advanced TRT are critically assessed and future research questions are outlined.

Influence of Different Heat Loads and Durations on the Field Thermal Response Test [PDF]
Energies, 2022 Geothermal energy exhibits considerable development potential in space heating. Shallow geothermal energy stored in the soil in the form of low-grade energy is mainly extracted via the ground source heat pump (GSHP) system.

Group thermal response testing for energy piles [PDF]
, 2015 ABSTRACT Thermal response testing is an in situ technique for characterising the thermal conductivity of the ground around a borehole heat exchanger. The test has seen renewed interest in recent years as an increasing number of ground heat exchangers are being constructed to provide renewable heating and cooling energy as part of ...
