    Abstract: A method for generating electricity and cold and a device for realizing same, consists in a closed absorption cycle in which a working body is a mixture of a low-boiling (refrigerant) component and a high-boiling (absorbent) component. The method involves evaporating a strong solution in a steam generator, thus forming a refrigerant vapor and a weak solution, expanding the refrigerant vapor in a turbine, thus producing work, and, after the turbine, absorbing spent vapor in an absorber, forming a strong solution. A distinguishing feature of the method consists in changing the concentration of a strong solution using two stages, including not only evaporation but also filtration. The proposed method and device allow for significantly increasing the efficiency of systems for generating electricity relative to analogous known methods.

  • Patent number: 9772127
    Abstract: A closed loop system utilizing a solar refrigerant turbocharger and pump in conjunction with a solar collector to operate a heating and cooling system for a building by utilization of a renewable energy source. The liquid pump within the solar turbocharger is used to boost the refrigerant pressures into the solar collector, the refrigerant absorbs heat inside the solar collector and changes phase from a liquid to a vapor. The vapor is expanded across the turbine causing the turbine to spin. The ability of the refrigerant to change phase or flash from a liquid to a vapor is due to the solar energy that is transferred from evacuated tubes into the solar collector manifold and into the refrigerant. The gas is routed to the solar turbo pump turbine to drive the compressor and liquid pump. The resulting fluid gas leaving the turbine is routed to the condenser for normal operation.
