Patent number: 8813514Abstract: A Geothermal Rail Cooling and Heating System is a reversible system process that accelerates heat transfer between the steel rail used in railway track and the adjacent earth. It is comprised of the Rail Heat Exchangers specially shaped to fit tightly inside the rail web, a refrigerant cycling on its physical condensing and evaporative characteristics, a mechanical and power supply system, and an underground tubing loop system for heat dissipation or absorption.

Publication number: 20120318474Abstract: The present invention relates to a ground circuit in a low-energy system, said ground circuit comprising a connection pipeline (3), collection pipe system (2) and a return pipeline (4) for circulating a transfer fluid. The ground circuit is utilized for transferring thermal energy recovered from its surroundings, for instance, to a heat pump (5) or the like. The present ground circuit collection pipe system (2) is characterized by consisting of a hollow profile (6) arranged to be a coil, whereby the hollow profile is connected at its first end to a connection pipeline (3) for conveying the transfer fluid along the hollow profile from the first coil end to the second, and at the second end of the coil the second end of the hollow profile is connected to the return pipeline (4) for conveying the transfer fluid from the hollow profile towards the place where used. At the opposite ends of this hollow profile there are advantageously arranged means for controlling the fluid flow provided therein.Type: ApplicationFiled: September 23, 2010Publication date: December 20, 2012Inventor: Mauri Antero Lieskoski

Publication number: 20120267444Abstract: The present invention relates to an artificial freezing apparatus and a freezing method therefor. The present invention includes a supporter for vertically moving a water ice maker over and under the surface of water; and the water ice maker for producing an ice while being vertically moved by the supporter and to fall down thus-produced ice into the surface of water. In accordance with the present invention as described above, the present invention can separate some from the water and expose it to the atmosphere to naturally freeze the separated water and return thus-produced ice to the surface of water to thereby accelerate the freezing process on the surface and thus make some ice on the surface when it is difficult to ice, and creating various additional effects such as preventing global warming, preserving ecosystems and the like.Type: ApplicationFiled: December 22, 2010Publication date: October 25, 2012Inventor: Hi-Ryong Byun

Patent number: 8291722Abstract: The present invention is an apparatus that includes a chamber rotor with a chamber and an extension rotor with an extension. The rotors are housed in a rotor case. A pressure cavity is at least transiently formed by the extension rotor and the chamber rotor. The present invention also includes a compressor that includes a chamber rotor with a chamber and an extension rotor with an extension where the extension is adapted to be received in the chamber when the rotors are synchronously rotated. The compressor also includes a power input shaft attached to the extension rotor and a gear assembly attached to the rotors that is adapted to insure the synchronous rotation of the rotors. A rotor case houses the rotors and has an intake port and an exhaust port. The present invention also includes an engine that is similar to the compressor and includes a spark plug. Methods of compressing, pumping and generating electricity and mechanical power are also part of the present invention.Type: GrantFiled: April 3, 2009Date of Patent: October 23, 2012Inventor: Jerome R. Lurtz

Patent number: 8161759Abstract: A method of and apparatus for 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, 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.Type: GrantFiled: October 31, 2007Date of Patent: April 24, 2012Assignee: Kelix Heat Transfer Systems, LLCInventors: John E.

Patent number: 8109110Abstract: A direct exchange geothermal heating/cooling system has a self-adjusting expansion valve and a bypass flow path to improve efficiency when the system operates in a heating mode. The expansion valve may operate based solely on pressure from the vapor refrigerant transport line. The system may alternatively include an accumulator, a compressor, and an oil separator, wherein an oil return line returns oil from the oil separator to the accumulator. Additionally, a direct exchange geothermal heating/cooling system may include a hot-gas bypass valve for diverting heated vapor refrigerant to the liquid refrigerant line. Finally, a direct exchange geothermal heating/cooling system having a sub-surface heat exchanger extending to a depth of at least 300 feet may use a refrigerant particularly suited for such an application.Type: GrantFiled: October 14, 2008Date of Patent: February 7, 2012Assignee: Earth To Air Systems, LLCInventor: B.
