Abstract
The geothermal heat utilization system is capable of supplying underground water of an upper aquifer from the first upper opening to the second upper opening via the first pipe, and capable of supplying underground water of a lower aquifer from the second lower opening to the first lower opening via the second pipe. Further, the geothermal heat utilization system is configured to pump hot water and at the same time, pump cold water.
Claims11
A geothermal heat utilization system, comprising:
- a first well that includes a first upper opening that opens in an upper aquifer and a first lower opening that opens in a lower aquifer;
- a second well that includes a second upper opening that opens in the upper aquifer and a second lower opening that opens in the lower aquifer;
- a first pipe;
- a second pipe;
- a first heat exchanger connected to the first pipe;
- and
- a second heat exchanger connected to the second pipe,
- wherein the geothermal heat utilization system is capable of supplying underground water of the upper aquifer from the first upper opening to the second upper opening via the first pipe,
- wherein the geothermal heat utilization system is capable of supplying underground water of the lower aquifer from the second lower opening to the first lower opening via the second pipe, and
- wherein the geothermal heat utilization system is configured to pump hot water as the underground water to be supplied from one of the upper aquifer and the lower aquifer, and at the same time, pump cold water as the underground water to be supplied from the other of the upper aquifer and the lower aquifer.
An operation method for a geothermal heat utilization system,
- the system comprising:
- a first well that includes a first upper opening that opens in an upper aquifer and a first lower opening that opens in a lower aquifer;
- a second well that includes a second upper opening that opens in the upper aquifer and a second lower opening that opens in the lower aquifer;
- a first pipe;
- a second pipe;
- a first heat exchanger connected to the first pipe;
- and
- a second heat exchanger connected to the second pipe,
- the method comprising:
- a step of supplying underground water of the upper aquifer from the first upper opening to the second upper opening via the first pipe;
- and
- a step of supplying underground water of the lower aquifer from the second lower opening to the first lower opening via the second pipe,
- wherein hot water as the underground water to be supplied from one of the upper aquifer and the lower aquifer is pumped, and at the same time, cold water as the underground water to be supplied from the other of the upper aquifer and the lower aquifer is pumped.
