Power Generation And Space Conditioning Using A Thermodynamic Engine Driven Through Environmental Heating And Cooling
US Patent:
7877999, Feb 1, 2011
Filed:
Apr 13, 2007
Appl. No.:
11/734854

Assignee:
Cool Energy, Inc. - Boulder CO
International Classification:
F01B 29/10, F02G 1/04, F01K 27/00, F01K 1/00, F01K 3/00, F03G 7/00, F03G 6/00
US Classification:
6064113, 60517, 606411, 606412, 60659, 60398
Abstract:
A thermodynamic engine is configured to convert heat provided in the form of a temperature difference to a nonheat form of energy. Heat is directed through a heating loop in thermal contact with a first side of the thermodynamic engine. A second side of the thermodynamic engine is coupled to an environmental cooling loop in thermal contact with an environmental cooling device. The thermodynamic engine is operated to dispense heat from the second side of the thermodynamic engine through the environmental cooling loop into the environmental cooling device. Operation of the thermodynamic engine thereby generates the nonheat form of energy from the temperature difference established between the first side and the second side of the thermodynamic engine.

Abstract:
A thermal source provides heat to a heat engine and or one or more thermal demands, including space and water heating and heat storage. Additionally the output of the heat engine may be used for local in situ electricity needs, or directed out over the grid. A system controller monitors conditions of the components of the system, and operates that system in modes that maximize a particular benefit, such as a total accrued desired benefit obtained such as reduced electricity cost, reduced fossil fuel use, maximized return on investment and other factors. The controller may use past history of use of the system to optimize the next mode of operation, or both past and future events such as predicted solar insolation.
Assembly For Sealing A Sliding Interface
US Patent:
2012021, Aug 23, 2012
Filed:
Dec 6, 2011
Appl. No.:
13/312837
Inventors:
Lee S. SMITH - Boulder CO, US

Brian Phillip Nuel - Boulder CO, US
International Classification:
F16J 15/16, F16J 9/00
US Classification:
277300, 277500, 277434
Abstract:
An assembly is disclosed for sealing the sliding interface between two objects capable of sliding or moving with respect to one another, but where the sliding interface must provide a substantial seal against pressure loss therethrough, such as where an assembly seals the sliding interface between a piston and a cylinder or between a rod and a bushing. Although some features of this invention would be beneficial in applications using a liquid lubricant, the invention is particularly beneficial in applications not using a liquid lubricant, where the materials of the piston, cylinder, and sealing system are chosen additionally for their ability to provide self-lubrication as they slide over each other, while providing low friction and a low wear rate during sliding.

International Classification:
F01B 29/10, F02G 1/04, F25B 9/00
US Classification:
60517, 60521, 62 6
Abstract:
Systems and methods for operating a thermodynamic engine are disclosed. The systems and methods may effect cyclic motion of a working fluid between hot and cold regions of a thermodynamic engine and inject a dispersible material into the working fluid at the hot or cold region during a heat-addition or heat-rejection process. The system and methods may also evacuate the dispersible material from the hot or cold region.
