openaire: EC/H2020/856602/EU//FINEST TWINS Funding Information: This study received funding from China Scholarship Council (No. 202006370019). The study received further funding from the FINEST Twins project, which is co-funded by the European Union (Horizon 2020 program, grant number 856602) and the Estonian government. The authors would like to thank Antti Säynäjoki from Aalto University Campus & Real Estate Ltd. for fruitful cooperation. In addition, the authors would like to especially thank Oleg Todorov and Markku Virtanen for the arrangement of measurement data for this study. Publisher Copyright: © 2022 The Authors Appropriate modeling of borehole thermal energy storage (BTES) system is crucial for accurate prediction of BTES-coupled ground source heat pump performance with accessible computational load. This study aims to validate 3-D numerical models developed in IDA ICE 4.8 and COMSOL for a large-scale asymmetric borehole field consisting of 74 groundwater-filled boreholes with average depth of 310 m in Otaniemi, Finland. Comparisons were conducted between the detailed-geometry IDA ICE and COMSOL borehole field models and between the detailed-geometry and simplified-geometry IDA ICE borehole field models. All these models were validated by 1.5-years brine temperatures measured by temperature sensors and a distributed temperature sensing monitoring system. The results show the detailed-geometry IDA ICE model can estimate the BTES inlet and outlet brine temperatures as well as the COMSOL model. The average inlet and outlet brine temperature differences against the measurement data in the detailed-geometry IDA ICE and COMSOL models were both within 1 ℃. The simplified-geometry IDA ICE models can predict the borehole field inlet and outlet brine temperatures with a similar high accuracy (within 1 ℃ against the measurement) and can reduce the computational time by 72 % less than the detailed-geometry IDA ICE model.
