FIELD: heat power engineering.
SUBSTANCE: device comprises pump, circulation circuit provided with two compressors in the top stage. Each of the compressors is connected with the condenser, throttle valve, and evaporator connected in series. The device is additionally provided with separating tank connected to the circulation circuit between two compressors in the top stage that separates the circulation circuit into two circuit, two steam-jet ejectors in the bottom stage interposed between the condenser, and compressor. The separating tank is additionally connected with the circulation circuit in the section between the nozzles of the steam-jet ejectors. The device has two regenerative heat exchangers each of which is interposed between the condenser and throttle valve. The evaporator is connected with the pump, to the top section of the separating tank, to the inlet of each steam-jet ejector, and to the outlet of each throttle valve.
EFFECT: enhanced efficiency.
