Energy Optimization of an Installation of Reversible Geothermal Heat Pump

The present agents of society are demanding more rational harnessing of energy and its more efficiency approaching. Geothermal energy is a renewable energy which uses the heat of the ground and besides, it can be used by everybody in all the world. About 10 meters below the Earth's crust, the Earth stays nearly a constant temperature between 283 and 288 K in nearly all locations. So geothermal drilling is a process whereby heat is taken from the Earth and used in a productive way for energy needs. The low enthalpy geothermal energy is more and more approached through the heat pump. So it is necessary to establish criteria to improve the efficiency of these devices as a way in both heating or cooling. The scope of this project is to study and to improve the ideal dimensions of the heat exchangers of the condenser, the evaporator and the desuperheater over a commercial prototype of a heat pump. For that, we have been monitoring the complete installation to study the pressures, the temperatures and the flow meters of the whole circuits. The purpose is to realize the simulation, the design, the installation and the monitoring of the new components to allow an experimental energy optimization.
