    摘要： A pair of organic Rankine cycle systems (20, 25) are combined and their respective organic working fluids are chosen such that the organic working fluid of the first organic Rankine cycle is condensed at a condensation temperature that is well above the boiling point of the organic working fluid of the second organic Rankine style system, and a single common heat exchanger (23) is used for both the condenser of the first organic Rankine cycle system and the evaporator of the second organic Rankine cycle system. A preferred organic working fluid of the first system is toluene and that of the second organic working fluid is R245fa.

    摘要： A machine designed as a centrifugal compressor is applied as an organic rankine cycle turbine by operating the machine in reverse. In order to accommodate the higher pressures when operating as a turbine, a suitable refrigerant is chosen such that the pressures and temperatures are maintained within established limits. Such an adaptation of existing, relatively inexpensive equipment to an application that may be otherwise uneconomical, allows for the convenient and economical use of energy that would be otherwise lost by waste heat to the atmosphere.

    摘要： A method and system for recovering oil is used in an organic rankine cycle (ORC) system to recover oil from an evaporator of the ORC system and return the oil to an oil sump. The ORC system includes an evaporator, a turbine, a condenser and a pump, and is configured to circulate a refrigerant through the ORC system. The oil recovery system includes a recovery line configured to remove a mixture of oil and refrigerant from the evaporator. The mixture of oil and refrigerant passes through a heat exchanger in order to vaporize liquid refrigerant in the mixture and produce a mixture of oil and vaporized refrigerant. A delivery line is configured to deliver the mixture of oil and vaporized refrigerant to the turbine, at which point the oil may be separated from the vaporized refrigerant and recycled back to the oil sump.

    摘要： A turbomachine includes a housing and a rotatable shaft, where at least a portion of the rotatable shaft is located in the housing. The turbomachine also includes a magnetic thrust bearing that axially positions the rotatable shaft and a radial bearing that centers the rotatable shaft. The turbomachine includes a flexure including a first portion secured to the housing and a second portion axially moveable relative to the first portion. The second portion of the flexure is connected to the radial bearing, and the second portion moves axially to eliminate thrust loads on the radial bearing and allow the magnetic thrust bearing to carry axial loads.

    摘要： The shaft (20) of an engine (19) is coupled to a turbine (28) of an organic Rankine cycle subsystem which extracts heat (45-48, 25) from engine intake air, coolant, oil, EGR and exhaust. Bypass valves (92,94, 96, 99) control engine temperatures. Turbine pressure drop is controlled via a bypass valve (82) or a mass flow control valve (113). A refrigeration subsystem having a compressor (107) coupled to the engine shaft uses its evaporator (45a) to cool engine intake air. The ORC evaporator (25a) may comprise a muffler including pressure pulse reducing fins (121, 122), some of which have NOx and/or particulate reducing catalysts thereon.
