Method and device for generation of electric power and cold using low-potential heat sources

A method for producing electric energy and cold using low-potential heat sources, comprising

• circulation of a solution comprising a refrigerant as a low-boiling component and an absorbent as a high-boiling component, with periodic heating and cooling said solution,
• evaporation of a high concentration the solution during heating with formation of a steam flows of the refrigerant and a weak solution of elevated temperature and pressure,
• using of the refrigerant steam flow in a heat engine with formation at a turbine exit of an exhaust steam of reduced temperature and pressure,
• decrease in temperature and pressure of the weak solution,
• absorption of the exhaust steam by the weak solution under cooling with formation of a strong solution,
• increase in pressure of the strong solution and feeding of the solution for evaporation,
• wherein
• the strong solution is divided into flows with increased concentration of the absorbent and flows with increased concentration of the refrigerant, whereas the flow with increased concentration of the absorbent being used as weak solution during absorption,
• while the flow with increased concentration of the refrigerant being employed during the evaporation as a high concentration solution after an additional increase in pressure and temperature.
