Fig. 1. The thermodynamic cycle of the BERS: 1-2 – working fluid heating and boiling in the vapour generator; 2-3 working fluid
expansion in the ejector nozzle; 3-4 and 5-4 – working and refrigerant fluids isobaric mixing at the evaporation pressure; 4-4’ –
vapour mixture compression in the ejector; 6 -8 and 7--9 – working and refrigerant fluids condensation in the fractionating
condenser and the refrigerant fluid condenser; 8-8’ – liquid refrigerant throttling to the evaporator; 9 -1 – liquid working fluid
feeding to the vapour generator; 8’- 5 –the refrigerant fluid evaporation
