Earth storage structural energy system and process for constructing a thermal storage well
A geothermal space conditioning and water heating system for a building structure comprises a battery of serially coupled thermal storage wells. Each well includes a dual concentric thermal conduction tube having an external circumference and an integrated earth interface and substantially moisture impervious clay platelet transition surrounding and at least double the tube circumference. The thermal storage battery has a cold port and a hot port maintained at a temperature greater than the cold port. A space conditioning arrangement is provided in which thermal transport fluid passes through a fan-driven radiator. A reversible heat pump has a radiator conditioned air coupled first heat exchanger and a downstream radiator fluid coupled second heat exchanger. A second heat pump has a first heat exchanger in thermal communication with a hot port coupled hot water heater and a cold port coupled second heat exchanger. A transient storage tank provides a time averaged uniform transport fluid temperature. Valving allows reversal of fluid from the hot and cold ports to and from the transient storage tank and the space conditioning arrangement as determined by multiple temperature sensors determining output states of a controller. The geothermal storage wells are established by circulating a mud in a well to stabilize the hole, running a conduit in the well and thereafter reverse-circulating a sand/gravel slurry through the conduit thereby packing the region between the conducting tube and the earth interface.
