<p>An improved ground source heat pump system wherein the subterranean piping installation comprises modular heat exchange units. Each modular heat exchange unit (36, 38, 40) comprises a plurality of parallel secondary or branch conduits (54, 56, 58, 54A). The use of multiple parallel secondary conduits significantly increases the heat exchange capacity of the system. Because of the increased efficiency of such a system, less piping is required, which in turn reduces the cost of labor and materials to install such a system and the area of land mass required to contain it. Moreover, because the heat exchange units are modular, they can be prefabricated at a remote site and then conveniently transported to construction site and installed much more quickly than the extended lengths of conventional piping.</p> |
