A method of cooling air includes a liquid coolant subsystem including a cool water source configured to hold water, an air cooling subsystem including an air chamber that contains air therein, an air conditioning apparatus including a heat exchanger of a liquid-to-air type having a heat sink in thermal communication, a fan assembly configured to move air along the heat sink of the heat exchanger, a thermostat, a temperature sensor, and a control circuit in electronic communication with the temperature sensor and the thermostat, a plumbing subsystem including an inlet piping component in fluid communication with heat exchanger, an outlet piping component in fluid communication with the exchanger, and a solenoid valve. The control circuit may be configured to activate the fan assembly and to open the solenoid valve, allowing for the transfer heat to water from the air moved by the fan assembly.

Systems include a well having a production casing and a production tubing positioned therein, forming an annulus there between. A packer is positioned in the annulus at a position sufficient to separate the annulus into a first portion and a second portion. The well further includes a tie-back conduit positioned in the first portion of the annulus and configured to allow heat transfer between a working fluid flowing through the first portion of the annulus and a production fluid flowing through the production tubing, thus separating the circulating working fluid from fluids in the second portion of the annulus. A working fluid loop is fluidly connected to the first portion of the annulus. Co-production methods, methods of modeling, and computer-readable media including the methods of modeling are disclosed.

An assembly and process for forming a two stage extruded pipe having a central inner sleeve and a pair of outer attached lobes. The central sleeve shaped (also termed a grout receiving tube) is produced in an initial extrusion operation, following which it enters a cross head operation where a pair of outer lobes are attached to cross sectional exterior surface locations according to a second stage extrusion operation so as to be integrally formed therewith. Other steps include cooling of the dual stage extruded pipe, as well as sectioning and stacking the pipe. Additional steps include forming elongated slots or apertures into the central sleeve portion of the finished extrusion, such in non-interfering fashion with the individual passageway defining and lobes.

The present invention provides a method for operating a plurality of independent, closed cycle power plant modules each having a vaporizer comprising the steps of: serially supplying a medium or low temperature source fluid to each corresponding vaporizer of one or more first plant modules, respectively, to a secondary preheater of a first module, and to a vaporizer of a terminal module, whereby to produce heat depleted source fluid; providing a primary preheater for each vaporizer; and supplying said heat depleted source fluid to all of said primary preheaters in parallel.

Building heating and/or cooling methods are provided that can include continuously distributing fluid from within conduits within a concrete floor of a building to conduits within grounds surrounding and/or supporting the building while transferring air to/from the interior of the building via a heat exchanger.

Building heating/cooling systems are provided that can include: a building comprising walls and concrete floors; fluid containing conduit within the concrete floors; circulating fluid within the conduit; a least one heat exchanger operatively associated within the building and configured to transfer air to/from the building; and processing circuitry operatively coupled to fluid circulation controls and heat exchanger controls.

An apparatus for collecting solid materials from a fluid is provided. The apparatus includes a conduit configured to allow the fluid to flow therethrough. The apparatus further includes a mesh extending across the conduit. The mesh is configured to allow the fluid to flow therethrough and to allow a solid material to precipitate out of the fluid onto the mesh. The apparatus further includes a support structure configured to support the mesh in position across the conduit.

The field of the invention relates to systems and methods for exchanging heat from the degradation, decomposition, and chemical/biochemical transformation of municipal, industrial, and other types of waste. In one embodiment, a heat extraction system may include a closed-loop fluid circulation piping channeled throughout at least one heat extraction well oriented throughout a waste mass. The piping is fluidly coupled to a heat exchanger. A first circulation fluid is circulated through the closed-loop circulation piping into various depths of the waste mass to transfer thermal energy between said mass and said heat exchanger. In one embodiment, the transfer of thermal energy between the waste mass and the heat exchanger is used as alternative energy method and to control at least one of shear strength, compressibility, and hydraulic conductivity of the waste mass.

A geothermal expansion spool assembly includes an integrated or single piece configuration. The geothermal expansion spool assembly comprises an upper portion adapted to directly couple to a production valve and a lower portion adapted to surround and engage with a surface casing of a geothermal well, wherein the upper and lower portion are permanently fixed to one another.

This invention relates to treated geothermal brine compositions containing reduced concentrations of silica, iron, and potassium compared to the untreated brines. Exemplary compositions of the treated brine contain a concentration of silica ranging from about 0 mg/kg to about 15 mg/kg, a concentration of iron ranging from about 0 mg/kg to about 10 mg/kg, and a concentration of potassium ranging from about 300 mg/kg to about 8500 mg/kg. Other exemplary compositions of the treated brines also contain reduced concentrations of elements like rubidium, cesium, and lithium.

A geothermal system having a flow station connected to a heat pump that is connected to a heat pump that is connected to a flow vector assembly. The flow vector assembly is connected to a heating coil and a cooling coil disposed within the ductwork of a furnace. The flow vector assembly may also be connected to a flow helix heat exchanger assembly.
