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 |
20090019876 | Irrigation reservoir cooling system - A combined space-cooling and irrigation system and method of operation. The system is operated by an automated control unit specifically programmed to manage cooling and irrigation needs as follows. When irrigation water is needed, the system pumps cool water from a municipal water supply, a well, or a deep pond, through a heat exchanger on the way to a reservoir. The water pumped through the heat exchanger cools fluid in a separate closed circuit. The cooled fluid in the closed circuit is then used for cooling purposes, for example, to cool the air circulated through a house or building using a commercially available fan coil unit. The reservoir releases collected water for irrigation purposes at appropriate times. | 01-22-2009 |

20110308268 | Geothermal Exchange Module and a Method of use with an Augmented Water Temperature System - The present invention is a geothermal exchange process to deliver water, in a closed loop ground to water system, at temperatures approaching that of ground water. Such water temperatures were heretofore only achievable with ground water systems. Optimum energy saving and performance of ground coupled heat pumps are directly linked to heat exchange between a circulating water loop and ground temperature. This invention allows for the optimization of energy and performance. The efficiency of heat pumps diminishes with descending outside air temperatures. This invention allows for the manipulation of entry water temperatures to stem the problem of diminishing efficiencies. The water system makes use of a uniquely designed geothermal exchange module with increased conductivity to maximize heat transfer into the water. | 12-22-2011 |
