Vertical hydraulic conductivity of borehole heat exchanger systems before and after freeze-thaw cycle stress
(International Ground Source Heat Pump Association, 2018)Quality assurance is a very important aspect in the planning, implementation and operation of borehole heat exchangers (BHE). Within the research project Quality Assurance for Borehole Heat Exchangers (QEWS) the hydraulic ... -
Video inspection of wells in open loop ground source heat pump systems in Norway
(International Ground Source Heat Pump Association, 2018)This paper presents results from video inspections of groundwater wells in Melhus and Elverum, in Norway. The method has identified iron hydroxides, bacterial growth and sand production as causes of clogging in different ... -
Virtual borehole for thermal response test unit calibration: Test facility and concept development
(International Ground Source Heat Pump Association, 2018)Precise calculation of the borehole length requires good estimation of the ground thermal conductivity. In practice, the ground thermal conductivity is measured in-situ at a specific location using what is referred to as ...
