Abstract:
1. A ground water restoration type terrestrial heat exchanger using an auto temperature bypass apparatus, comprising: a pipe well drilled in the ground; a ground water outlet pipe inserted into the pipe well so as to output ground water from the pipe well; a pump installed at the ground water outlet pipe; a heat exchanger in which the ground water pumped out is circulated to effect a terrestrial heat-exchange; a collection pipe connected to the heat exchanger to restore the ground water to the pipe well; a connection pipe connected between the pump and the heat exchanger; an auto temperature bypass apparatus installed at the connection pipe so as to automatically bypass the ground water from the connection pipe when a temperature of the ground water arrives at a predetermined value; a discharge pipe connected to the auto temperature bypass apparatus through which the bypassed ground water flows; a ground water restoration hole adjacent to the pipe well, the discharge pipe being inserted in the ground water restoration hole to restore the ground water nearby the pipe well; a filter unit provided at the discharge pipe so as to filter the ground water bypassed; and a booster pump provided downstream of the filter unit.
