Method and device for converting thermal energy into electricity, high potential heat and cold

A method of converting thermal energy into electricity, greater-potential heat and cold involving:

• formation of a flow of refrigerant vapor and a flow of lean solution at elevated temperature and increased pressure from a strong solution,
• lowering the temperature and pressure of the refrigerant vapor through its expansion with transforming its energy into usable forms and producing a spent vapor flow,
• absorption of the reduced-pressure refrigerant vapor in the lean solution proceeding with the release of thermal energy and the formation of a strong solution,
• cooling the lean solution, heating the strong solution formed during the absorption, as well as
• increasing the pressure of the solution,
• wherein the refrigerant vapor, when work being done, is expanded to the temperature of the lean solution directly before absorption with subsequent absorbing the vapor in the lean solution.

An apparatus for converting thermal energy into electricity, greater-potential heat and cold comprising:

• a boiler with a separator for evaporation of a refrigerant and its separation from a solution;
• a heat engine connected to the separator with conveying pipelines for feeding a refrigerant vapor and
• a condenser with conveying means for feeding into the condenser the vapor and for removing from it the liquid refrigerant to an evaporator with an expansion valve,
• an absorber with conveying means for feeding into the absorber the refrigerant vapor and a lean solution, and with conveying means for delivering a strong solution from the absorber into the boiler,
• a pump for increasing a pressure and a circulation of the solution,
• a regenerative heat exchanger and a cooler,
• wherein the cooler has external cooling, is installed between the separator and the absorber in order to ensure the heating of the external heat carrier and a decrease in the temperature of the lean solution ahead of the absorber.
