Abstract
Common types of geothermal heat exchange, the surface and the depth is characterized by demanding uneven ground. Uniformity thermal load of the massive and efficiency may be a solution in the sense of optimizing energy storage capacity and therefore reduced surface / volume of land used.A solution atypical geothermal heat exchanger, shallow, variable spatial geometry using cylindrical or tapered, which compared with geothermal drilling or pilots, presents significant recovery in terms of thermal capacity of the ground.For the spiral pipe conducted with constant diameter is maintained disadvantage loading / unloading uneven ground. The situation is radically altered when using the spiral geometry of tapered or cylindrical modular charge transfer areas to which it is directly proportional to the reduction in temperature of the work and its evolution, leads to a transfer of that charge / discharge uniformly. From a functional perspective and energy, this solution is obvious superior to any surface or deep usual, the heat transfer in the heat exchanger is variable. The novelty of the proposed solution is a favorable argument optimizing surface geothermal exchanger used in making reversible heating / cooling with solar energy.
