Experimental dataset of the Smart Compact Heat Transfer Station (SCHTS) mobile laboratory: time series, operating regimes, and processed results

Version 1.0.0 of a publication-neutral experimental dataset from the first-generation Smart Compact Heat Transfer Station (SCHTS) mobile laboratory. The record contains selected archived five-minute heat-pump outlet-water-temperature series for experimental Regimes R0–R5; manually derived comparative heat-pump start counts for equal 12 h observation windows; complete 18 °C → minimum → 18 °C control intervals; immediate post-minimum temperature rises; measurement metadata; a data dictionary; source-provenance and quality-control documentation; publication mapping; neutral PNG/SVG reproducibility plots; and processing code. Original local timestamps are retained. No smoothing, resampling, additional interpolation, or synthetic data points were used. The secondary load circuit was inactive during the analysed intervals. The complete archived source workbook, journal manuscripts, graphical abstracts, and final annotated publication figures are not distributed.
