148 Heat pump-driven external combustion engine US10316033 2002-12-11 US06715313B1 2004-04-06 Atsusi Takafu
There are many heat sources on the earth, and those heat sources radiate heat continuously. Though some of such heat sources are utilized with heat exchange technologies now, they can't deliver power to us effectively. In addition, though external combustion engines can utilize the heat generated from fuel combustion, they let out much carbon dioxide at the same time. This invention has solved above problem. In this invention, the driving energy for the external combustion engine (2) comes from the heat ventilation part/absorption part of the heat pump (1); wherein said heat pump (1) is a metal oxide heat pump (11), and said external combustion engine is a Sterling Engine (21) or a thermo-metal engine (22).
149 METHOD OF HEAT TRANSFORMATION FOR GENERATING HEATING MEDIA WITH OPERATIONALLY NECESSARY TEMPERATURE FROM PARTLY COLD AND PARTLY HOT HEAT LOSS OF LIQUID-COOLED INTERNAL COMBUSTION PISTON ENGINES AND DEVICE FOR EXECUTING THE METHOD US09601503 2000-08-02 US06484501B1 2002-11-26 Hans Otto Mieth; Peter Thomsen; Marcus Gunther
The invention relates to a process of heat transformation to convert the low-temperature waste heat from cooling circuits of block-type thermal power station (BTPS) reciprocating-piston combustion engines into steam or other heating media of a temperature required for operation by adopting the principle of the high-temperature heat pump according to which the low-temperature heat produced by recooling the engine cooling circuits to their required inflow temperature required by construction is transferred to a liquid working medium, is absorbed by the working media vapors by partial evaporation, and is brought, by compressing and condensing the working medium vapors, to the temperature of the in-plant heating media and is transferred to them. It is an object of the invention to provide a heat transformation process and devices for realizing the process according to the principle of the high-temperature heat pump using mechanical vapor compression by means of which the waste heat not only of the hot exhaust gas, but also the one of a proproportion as large as possible of the low-temperature waste heat from the cooling circuits for the cylinders, the lubricating oil, and the charging air/fuel mix may be used up to a lower temperature limit to be fixed for each project by conversion into the in-plant common heating medium in a technically reliable manner and at an economical relationship between the investment and operating expenditures to the output from the recuperated energy in reciprocating-piston engine BTPS for the heat supply to commercial and industrial enterprises. This is attained by the fact that inventive connections and devices prevent a drop below the ambient pressure in the critical low-temperature range and in all of the operating conditions of the heat transformer and the energy required for vapour compression is reduced to a minimum and, using steam expansion or hot-air prime movers, is gained completely or in part from the exhaust gas content of the BTPS engine (FIG. 1).

160 Combustion-powered refrigeration with decreased fuel consumption US090127 1987-08-27 US4745768A 1988-05-24 Hans P. Schorr; Daniel J. Dessanti
In refrigeration systems wherein the refrigerant compressor is driven by a prime mover powered by combustion of a fluid fuel, a notable saving in fuel consumption is achieved by utilizing waste heat in the hot exhaust gases from the prime mover in an absorption refrigeration unit that chills a coolant stream circulated to the condenser for the compressed refrigerant. Existing combustion-powered refrigeration systems can be improved by adding a lithium halide absorption unit to utilize heat in the exhaust gases to produce refrigeration that is used to condense the compressed refrigerant. A combustion turbine coupled to a centrifugal compressor is a preferred combination of prime mover and refrigerant compressor for economically producing tonnage refrigeration.
