A method for converting heat energy into mechanical, electrical and/or thermal energy, includes two circuits which are connected one common subsection. The first circuit has an expansion apparatus, and the common subsection is connected to the first and second circuit via a jet compressor. A working medium is routed in the first circuit and a propellant is routed in the second circuit and a mixture of working medium and propellant is routed in the common subsection. The mixture is separated into a working medium stream and a propellant stream in a separation apparatus. The working medium is recirculated into the first circuit and is supplied to an evaporator unit. The evaporated working medium is supplied to the expansion apparatus and subsequently to the jet compressor. The separated propellant is recirculated into the second circuit and is supplied to a collector and is then supplied to the jet compressor.

Conversion of heat into mechanical energy by means of a jet compressor

A method of converting heat energy generated in an evaporator to mechanical energy by expanding an evaporated working fluid includes evaporating the working fluid in the evaporator and expanding the evaporated working fluid in an expansion device. The expansion is in a low-pressure expansion device which is formed as a roots blower in which the working fluid is expanded and heat energy is converted to mechanical energy.

Method of transforming heat energy to mechanical energy in a low-pressure expansion device

A method and a system for converting heat energy contained in fluids as noticeable or latent heat to mechanical energy, wherein a working fluid is evaporated by means of the heat energy, if necessary after transformation to a higher temperature level, by means of one or more series-connected heat pumps and expanded in an expansion device, and wherein the heat energy is at least partially converted to mechanical energy. The expansion occurs in a low-pressure expansion device and the energy contained in the expanded evaporated working fluid is recyclable into the evaporating device in an evaporating unit, which is usable for evaporating additional working fluid.

Method and installation for converting thermal energy from fluids into mechanical energy

A method for converting heat energy to mechanical energy includes expanding an evaporated working fluid with an expansion device connected to an evaporator. The expansion is carried out in a low-pressure expansion device and the energy contained in the expanded evaporated working fluid can be recycled into the evaporator and utilized for evaporating additional working fluid.
