Effective Thermal Conductivity and Borehole Thermal Resistance in Selected Borehole Heat Exchangers for the Same Geology

open access: yesEnergies, 2022
Investigating the constructions of borehole heat exchangers with high efficiency (unit heat transfer between the heat carrier and ground) is important. One of the means to improve efficiency is the use of the most efficient construction of the borehole ...

Study on the Influence of Borehole Heat Capacity on Deep Coaxial Borehole Heat Exchanger [PDF]

open access: yesSustainability, 2022
Based on a semi-analytical model established previously for heat transfer in coaxial borehole heat exchangers, the influences of the heat capacities of different parts of the borehole (fluid, pipes and grout) on the performance of deep coaxial borehole heat exchanger (DCBHE) are analyzed.

Simulation Model for Borehole Heat Exchangers [PDF]

open access: yesLinköping Electronic Conference Proceedings, 2018
Abstract Seasonal thermal energy storage (STES) offers a solution to address the mismatch between production and consumption by storing the produced excess heat for later use. Borehole heat exchangers (BHEs) are one of the sensible STES technologies. In this paper, a long-term simulation model for BHEs was developed.

Improved Analysis of Borehole Heat Exchanger Performance

open access: yesEnergies, 2023
This paper provides recommendations for improved analyses of the performance of ground-coupled heat pumps. Most research on ground-coupled heat pumps focuses on improving the performance of borehole heat exchangers (BHE) and reducing system costs. However, the potential improvements are mainly assessed at the BHE level rather than considering the ...
