FIELD: power industry.
SUBSTANCE: invention can be used in devices for conversion of heat energy to mechanical energy. A structure for conversion of heat energy to mechanical energy includes line circuit (3), circulation device (4) for circulation in line circuit (3) of a zeotropic mixture of cooling agents, which includes the first cooling agent and the second cooling agent, evaporator (6), heat source (7), turbine (9) and condenser (12). The first cooling agent has evaporation temperature that is higher than the second cooling agent at similar pressure. In evaporator (6) a mixture of cooling agents is evaporated by means of heat source (7). Turbine (9) is brought into movement by evaporated mixture of cooling agents. In condenser (12) the mixture of cooling agents is cooled so that it is condensed. There is a control device having a possibility of evaluation whether the mixture of cooling agents is fully evaporated in evaporator (6), and in case the situation is as described above, the structure is changed over to a low-effective state. When in a low-effective state, non-fully evaporated mixture of cooling agents, which leaves the evaporator, is supplied to separating device (14), in which some part of the mixture of cooling agents, which is in a liquid form, is separated from some part of the mixture of cooling agents, which is in a gaseous form; after that, only the gaseous part of the mixture of cooling agents is sent in the direction to the turbine in line circuit (3). When temperature of heat source (7) increases inversely to high temperature, the structure is changed over to a high-effective state, in which the separated liquid mixture of cooling agents is discharged back to line circuit (3). The invention describes a conversion method of heat energy to mechanical energy.
EFFECT: possible conversion of heat energy from a heat source with reduced temperature.
