The analysis of long-term borehole heat exchanger system exploitation
Computer Assisted Methods in Engineering and Science, 2017 The key issue in designing borehole heat exchangers (BHE) is the long-term performance of the ground source heat pump (GSHP) systems. The performance directly reflects economic profitability and depends on a large number of parameters including rock ...

Optimal sizing of borehole heat exchangers
Strojarstvo : časopis za teoriju i praksu u strojarstvu, 2009 The heat pumps coupled to the borehole heat exchangers (BHE) can serve for heating and/or cooling of buildings. Optimal sizing of BHE is important because of high drilling costs and importance of matching borehole thermal capacity with the capacity of the heat pump.
