Geo-Thermal Air Coil

Abstract

A system designed to harness the natural energy of the sun and earth, by creating an energy exchange between the soil, using air as the medium. The medium, air, is also the desired product in its conditioned form. The energy exchanged in the system is in a harmonious relationship with season soil variation so as to produce constant air temperature regardless of season, or ambient air temperature.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a non-provisional application of provisional patent application No. 61 / 634,581, filed on Mar. 2, 2012, and priority is claimed thereto.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.BACKGROUND[0003]The interest in acquiring geothermal energy from the earth is great due to the tremendous potential benefit it offers. Failure to master the technology, however, results in limitations which are found in current geothermal systems. Balance with natural forces which this patent refers to as “seasonal soil variation” is a fundamental part in overcoming these limitations. This patent will address current shortcomings, by offering a specific design which offers a revolutionary new improvement, constant air temperature production.[0004]The first law of thermodynamics teaches that energy can neither be created nor destroyed. Many conditions energy is something that cannot be observed by the human eye, ther...

AI Technical Summary

Benefits of technology

The patent text describes a method for improving the energy transfer in geothermal systems. By increasing the rate of energy transfer using air or gas, the amount of tube length required for energy transfer is reduced. Additionally, air can be used to gain temperature change at deeper levels in the soil without risking energy transfer in areas where seasonal soil temperatures cannot reach. This leads to more efficient energy transfer in geothermal systems.

Problems solved by technology

Failure to master the technology, however, results in limitations which are found in current geothermal systems.

Today's geothermal systems lack a complete accounting of the influences that interact within a system, and therefore come short in their abilities to correctly harness this great energy source.

Geothermal systems have the potential to be some of the cheapest energy produced, yet they account for one of the smallest producers of energy in today's market.

Until now, this has been due to the limitations that our found in these systems.

Since the first law of thermodynamics teaches that the total energy in a system will remain constant in that system, it became essential that in the designing of a heat exchange system that all energy is accounted for and balanced, otherwise the energy being transferred will end up in an undesired location, and cause system the system to become unbalanced.

The first major limitation that geothermal systems face is the medium for the exchange.

Liquids have a major limitation in geothermal applications which is their natural capacity to hold and transfer energy.

This increases in length allows additional room for energy transfer to accomplish a specific system requirement, but does not correct the original obstacle of using a medium which transfers energy at a rate faster than the rate soil can absorb.

This increases in length allows additional room for energy transfer to accomplish a specific system requirement, but does not correct the original obstacle of using a medium which transfers energy at a rate faster than the rate soil can absorb.

This brings up a secondary limitation in a liquid geo-thermal system which is tube size.

(FIG. 4a) Most liquid geothermal system do not use a 12 inch tube or larger tubes in general because of the fundamental problem that liquids can hold large amounts of energy and will transfer more energy than the soil can hold.

Air lacks the ability to carry large amounts of energy compared to solids or liquids.
