Abstract
An improved efficiency method and device for converting thermal energy into mechanical energy, and then, preferably, into electricity and/or refrigerating energy. A partially liquid stream fc0 of fluid FC is implemented; thermal energy is transferred to the stream fc0; the heated stream fc0 is sprayed to generate a fragmented stream fc1 of fluid FC. Simultaneously a partially liquid stream ft0 of fluid FT is implemented; thermal energy is transferred to the stream ft0 to generate a stream ft that may be in liquid form or a saturated liquid/vapor mixture; stream f1 is expanded in a chamber which also receives fragmented stream fc1 to form a two-phase mixed stream fc1/t whose kinetic energy is converted into mechanical energy which is optionally transformed into electrical energy or into refrigerating energy.
