NOVELTY - The system has a ground circuit (1), an augmentation circuit (2), a refrigerant loop (3), a refrigerant/water heat pump (4) , an augmentation water/water heat exchanger (5) and several geothermal exchange modules (111). The refrigerant/water heat pump links ground circuit with refrigerant loop. The augmentation water/water heat exchanger links the augmentation circuit with the ground circuit. Each geothermal exchange module comprises a thin wall outer shell, an inner pipe, an outer passageway, an inner passageway, an end plate, an o-ring seal, and optional tie rod.    USE - Geothermal exchange module and augmented thermal exchange system used in closed loop ground/water system.    ADVANTAGE - As the improved heat transfer results in greater operating efficiencies for geothermal heating and allows for the manipulation of entry water temperatures, the system improves geothermal heat exchange and heat pump performance. As the augmented booster boosts the heating performance of the heat pump, the augmented booster prevents the freezing of the water within the piping. As the optimum energy saving and performance of ground coupled heat pumps are directly linked to heat exchange between a circulating water loop and ground temperature, the system allows for the optimization of energy. As a spacer separates a module and allows each module to maximize the harvest of heat, the actual cylinder length while increasing the effective length per bore can be minimized. As the thermal output can be increased and in heating dominant climates the size of the geothermal field can be reduced, the initial system costs can be reduced. Since the harvesting of the ground heat is maximized when the cylindrical modules are utilized in parallel, the water output temperature is able to approach that of an underground stream. As the water system makes use of a uniquely designed geothermal exchange module with increased conductivity, the heat transfer into the water can be maximized. Hence the system is modular, can be manufactured in huge quantity at low cost, the system is suitable for factory assembly, the module can be easily installed with basic equipment and the module is relatively light in weight.
