GROUND WATER RESTORATION TYPE TERRESTRIAL HEAT EXCHANGER USING AUTO TEMPERATURE BYPASS APPARATUS

摘要

An underground water restoration type ground heat exchanger using an automatic temperature bypass device is provided to restore the underground water to the original temperature with the ground heat by discharging the underground water when the temperature of the underground water is inappropriate for the heat exchange of the heat exchanger. An underground water restoration type ground heat exchanger includes an automatic temperature bypass unit(70) installed in a connection pipe(60). The automatic temperature bypass unit discharges the underground water through a discharge pipe(80) branched from the connection pipe when the temperature of the underground water flowing out from an outflow pipe(20) of a well(10) reaches a set temperature. The discharge line is inserted in an underground water restoration hole(90) so that the discharged underground water is recovered approximately to the initial temperature by the underground water restoration hole.
