Abstract

A geothermal heat recovery device includes a circulation flow path provided with a circulation pump, a heat medium pressurized by the circulation pump circulating through the circulation flow path in a hot liquid state; a heat exchanger installed underground and configured to heat the heat medium flowing through the circulation flow path with underground heat; a binary electricity generation device configured to recover, as electrical energy, thermal energy from the heat medium heated in the heat exchanger; a bypass path connected to the circulation flow path; and an adjustment mechanism configured to adjust a flow division ratio between a flow rate of the heat medium flowing into the heat exchanger and a flow rate of the heat medium bypassing the heat exchanger through the bypass path.
