일반적인 설명

The Computer Controlled Geothermal Energy Unit with Two-Well System, "EGTWC", is a laboratory scale unit designed to study a two-well system used for the exploitation of thermal energy stored under the Earth’s surface.

The main element is a tank with one working section and two side chambers, one for the inlet and the other for the outlet of water. The sand bed through which the groundwater flows is located in this tank. Its flow can be adjusted by height-adjustable overflows. The groundwater level in the working section can be visualized by manometric tubes.

It is a self-contained unit with a water supply tank (groundwater simulation) from which a computer controlled pump drives the water to the sand bed chamber. Before entering the supply chamber, the water is heated by a computer controlled heating element, allowing to control the groundwater temperature.

The water crosses the working section, where there is a two-well system, a production and an absorption one. In the production well, wateris pumped into a plate heat exchanger to transfer its thermal energy to an external flow (working fluid). The flow of groundwater pumped to the exchanger can be adjusted and the unit has the measurements of flows and temperatures of both currents allowing the realization of the energy balance.

The working fluid flow to be heated in the exchanger can be tap water from the laboratory or water from EDIBON recommended element "TERA", suitable to work with this unit.

At the exit of the exchanger, water flows towards the bottom of the absorption well, leaving the working section towards the supply tank through the outlet chamber.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
