Two thermal performance test (TPT) datasets of a single U-tube borehole heat exchanger with inlet setpoint temperatures of 30?°C and 40?°C.

ABSTRACT: The presented thermal performance test (TPT) datasets were related to the research article "New perspectives in thermal performance test: Cost-effective apparatus and extended data analysis" (Choi et al., 2018), where a new TPT apparatus was developed by adding a solid-state-relay and a proportional-integral-derivative (PID) controller to a thermal response test apparatus. Using the developed apparatus connected to a 50-m-long vertical ground heat exchanger, two TPTs were conducted for 144?h with inlet setpoint temperatures of 30?°C and 40?°C. The raw data were measured at 5?s intervals and consisted of the inlet, and outlet fluid temperatures, and the flow rate. The attached MATLAB script allows users to easily filter the data at user-specified time intervals. Moreover, the execution of code provides two additional quantities: heat injection rate and unit heat exchange rate. The datasets are shared for the following purposes: (1) performance comparison of various ground heat exchangers using the unit heat exchange rate (2) comparison of the control performance of a newly developed TPT apparatus, (3) validation of an analytical or numerical thermal response model, and (4) validation of a parameter estimation algorithm.
