| 20080196859 | Method of transferring heat energy between a heat exchanging subsystem above the surface of the earth and material therebeneath using a coaxial-flow heat exchanging structure generating turbulence along the outer flow channel thereof - A method of transferring heat energy between a heat exchanging subsystem installed above the surface of the Earth, and material beneath the surface of the Earth, by installing one or more coaxial-flow heat exchanging structures in the material beneath the surface of the Earth. Each coaxial-flow heat exchanging structure has inner and out flow channels along which aqueous-based heat transfer fluid is circulated. Turbulence is generated in the aqueous-based heat transfer fluid flowing along the outer flow channel, thereby improving the transfer of heat energy between the aqueous-based heat transfer fluid and material beneath the surface of the Earth along the length of the outer flow channel. | 08-21-2008 |
| 20080209933 | System for exchanging heat within an environment using a coaxial-flow heat exchanging structure with helically-finned tubing - An coaxial-flow-flow heat exchanging structure having a proximal end and a distal end for exchanging heat between a source of fluid at a first temperature and the environment (e.g. ground, water, slurry) at a second temperature. The coaxial-flow-flow heat exchanging structure comprises a thermally-conductive flowguide tube having a hollow conduit extending from said proximal end to said distal end. A helically-finned tubing is disposed within the hollow conduit of said thermally-conductive flowguide tube, and has a central conduit for conducting a heat exchanging fluid, from said proximal end, along the central conduit towards the distal end, and returning back to the proximal end along a spiral annular flow channel formed between the thermally-conductive flowguide tube and the helically-finned tubing. | 09-04-2008 |
| 20080210402 | Method of incrasing the rate of heat energy transfer between a heat exchanging subsystem above the surface of the earth and material therebeneath using a coaxial-flow heat exchanging structure generating turbulence along the outer flow channel thereof - A method of transferring heat energy between a heat exchanging subsystem installed above the surface of the Earth, and material beneath the surface of the Earth, by installing one or more coaxial-flow heat exchanging structures in the material beneath the surface of the Earth. Each coaxial-flow heat exchanging structure has inner and out flow channels along which aqueous-based heat transfer fluid is circulated. Turbulance is generated in the aqueous-based heat transfer fluid flowing along the outer flow channel, to increase the rate of heat energy transfer between the aqueous-based heat transfer fluid and material beneath the surface of the Earth along the length of the outer flow channel. This in turn increases the rate of heat energy transfer between the heat exchanging subsystem installed above the surface of the Earth and material beneath the surface of the Earth. | 09-04-2008 |
| 20090250200 | Coaxial-flow heat transfer structures for use in diverse applications - An coaxial-flow heat exchanging structure having a proximal end and a distal end for exchanging heat between a source of fluid at a first temperature and the environment (e.g. air, ground, water, slurry etc.) at a second temperature. The coaxial-flow heat transfer structure comprises: a thermally conductive outer tube section, and an inner tube section having an inner flow channel and being coaxially arranged within the outer tube section. An outer flow channel is formed between the inner and outer tube sections, and helically-extending turbulence generator is provided along the outer flow channel, so as to create turbulence along the flow of heat exchanging fluid flowing between the inner and outer flow channels, and thereby increasing the heat transfer through the walls of the outer tube section to the ambient environment. | 10-08-2009 |

| 20110220320 | Method of and apparatus for interfacing geothermal equipment (GTE) in a building with a ground loop heat exchanging (GLHE) subsystem installed in the deep earth environment outside of the building - A geothermal system including geothermal equipment (GTE) for transferring heat energy in a building. A ground loop heat exchanging (GLHE) subsystem is interfaced with the GTE, and a plate heat exchanger (PHE) for interfacing the GTE and the GLHE subsystem. The PHE establishes a first hydraulic loop between the GTE, and the PHE. The PHE established a second hydraulic loop between the GLHE subsystem and the PHE. The volumetric flow rate within the second hydraulic loop is greater or less than the volumetric flow rate within the first hydraulic loop. The PHE exchanges heat energy between the first and second hydraulic loops so that the GLHE subsystem is operated at inlet water temperatures that enable maximum heat transfer rate (HTR) performance when the GTE is fully loaded. | 09-15-2011 |
