Data set from 2nd May 2024 to 12 May 2024 of a heat extraction test on a planar trench collector

This data set provides two different temperature measurements (PT100 and thermistors), as well as the determination of the volumetric water content and the bulk electrical conductivity of the subsurface. During the observation period, heat was extracted at a rate of approximately -0.7 kW. Unfortunately, the compressor ceased operation despite continued requests from the control system on May 11th at around 18:50. Due to the presence of a buffer tank and the continued volume flow, the exact time of compressor failure cannot be determined. On May 2nd at 15:57, both fluid circulation and heat extraction were initiated. The test was conducted with a constant volume flow of 0.35 m³/h, which remained unchanged until the end of the data set.
