Validation of borehole heat exchanger models against multi-flow rate thermal response tests
Geothermics（2018）
Abstract
•An improved model has been validated for borehole heat exchangers.•Proposed model accounts for transit time effects and short-circuiting heat transfer in U-tube heat exchanger.•Model is validated against two multi-flow-rate thermal response tests.•Weighting factor applied to inlet and outlet fluid temperatures estimates mean temperature.
