An experimental investigation of the influence of intermittent and continuous operating modes on the thermal behaviour of a full scale geothermal energy pile

摘要

Heat pumps connected to geothermal energy piles have variable operating hours. These variable hours\udcan affect the thermal behaviour of these piles. Some key findings are presented for intermittent (16\udhour) and continuous (24 hour) cooling modes in this abstract. It is found that the 16 hour cooling\udmode is more beneficial in terms of energy extraction, ground recovery, pile temperature and strain\udrecovery.
