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 |

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.

20160040911 | Cold island effect device - The cold island effect belongs to a phenomenon of climate change. At present, human research on the cold island effect is only limited to the field of science, and does not involve the technical field of invention. The present invention realizes the first application of the cold island effect principle in the technical field. The cold island effect device of the present invention comprises a plurality of reflecting devices. The reflecting devices are installed above the ground, the water surface or the building, and the reflecting planes thereof are parallel to the horizontal plane or are inclined. Most of sunshine can be reflected back to the space, so that a relatively cryogenic cold island is formed on the surface region where the reflecting devices are located and the cold island effect is formed through the interaction of ambient atmosphere, thereby achieving the purposes of heatstroke prevention and temperature reduction and drought resistance and moisture preservation. | 02-11-2016 |
20160054032 | PHASE-CHANGE COOLING OF SUBTERRANEAN POWER LINES - A cooling system for a subterranean power line may include a cooling tube configured to house a fluid. Heat generated by the subterranean power line may be radiated and/or conducted to the cooling tube and absorbed by the fluid within the cooling tube. As the fluid heats up, it may change phase from a liquid to a gas. The hot gas may rise to a heat-exchanging condenser configured to dissipate the heat and condense the fluid back into a liquid. The cool, condensed liquid my return from the heat-exchanging condenser to the cooling tube. Risers, gas transport tubes, pressure regulation systems, fluid storage tanks, and other components described herein may increase the efficiency of the cooling system and/or otherwise improve the viability of the cooling system for subterranean power lines. | 02-25-2016 |
20160069617 | HEAT RECOVERY APPARATUS AND METHOD - A grey water heat recovery apparatus has first and second passes arranged in counter-flow orientation. The heat recovery apparatus is made from commonly available materials. The heat recovery apparatus has a hot side for grey water, and a cold side for fresh water supplied under pressure. The heat recovery apparatus is used to pre-heat water for a water heater, and extracts heat from the grey water drains of a building in which the grey water drains are segregated from the sewage drains. The fresh water is carried in copper or stainless steel coils or linear tubing modules in series, each coil or linear tubing module being immersed in a grey water sump in a cylindrical plastic pipe. The water level in the sump is determined by the drain outlet level, and is high enough to immerse at least the dominant portion of the fresh water coil in grey water. The coils have a return leg such that both ends of the fresh water coil are carried out through the same upper end pipe closure, without a pressurized line wall penetration in the walls of the plastic pipe. The entire assembly may be enclosed in a unitary external housing with easily accessible connection fittings. | 03-10-2016 |

20160123629 | System and Method for Geothermal Heat Exchange - Apparatus and method transfer heat between a geothermal mass and a geothermal heat exchange unit embedded within the geothermal mass, utilizing a geothermal heat exchange system comprised of the heat exchange unit. The unit includes a chamber enclosed by plate-like walls presenting a very large heat transfer area. The walls are spaced apart by a small distance compared to the heat transfer area, configuring the chamber to contain a thin, film-like volume of a liquid heat exchange medium. The heat exchange medium is flowed into and out of the chamber at a prescribed rate of flow, and the capacity of the chamber is such that the volume of heat exchange medium contained within the chamber during operation of the geothermal heat exchange system is great enough to enable the flowing heat exchange medium to mix with static, dwelled heat exchange medium maintained within the chamber as heat exchange medium flows through the chamber at the prescribed rate of flow and is circulated in the system. | 05-05-2016 |

20160377303 | HIGH EFFICIENCY HEATING AND/OR COOLING SYSTEM AND METHODS - HVAC systems and methods for delivering highly efficient heating and cooling using ambient air as the working fluid. A plenum has an upstream inlet and a downstream outlet, each in fluid communication with a target space to be heated or cooled. Ambient air is drawn into the inlet at an incoming pressure and an incoming temperature. The inlet and outlet are gated, respectively, by first and second rotary pumps. A heat exchanger in the plenum transfers heat into or out of the air, provoking a change in air volume within the plenum. Work is harvested in response to change in air volume. The systems and methods can be configured to replace a traditional blower fan used to circulate the interior and exterior air. The systems and methods can be configured to implement a technique referred to as Convergent Refrigeration. | 12-29-2016 |
