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 power conversion system which uses a plurality of transistors to convert DC power to AC power is made more efficient by the use of liquid refrigerant to cool the transistors. A plurality of passages are formed in a cold plate on which the transistors are mounted, and liquid refrigerant is flashed into the passages to cool the cold plate and the transistors. The liquid refrigerant can by derived from a condenser from an organic rankine cycle or a vapor compression cycle.

摘要： In order to effectively extract the waste heat from a reciprocating engine, the normal heat exchanger components of an engine are replaced with one or more heat exchangers which have the motive fluid of an organic rankine cycle system flowing therethrough. With the heat transfer in the plurality of heat exchangers, the engine is maintained at a reasonable cool temperature and the extracted heat is supplied to an ORC turbine to generate power. The heat is derived from a plurality of sources within the reciprocating engine, and at least two of those sources have their fluids passing through the same heat exchanger. In one embodiment, the engine coolant and the engine lubricant pass through the heat exchanger in the same direction, and the ORC motive fluid passes therethrough in a counterflow relationship.
