FIELD: devices for transformation of thermal energy. SUBSTANCE: low-pressure working medium is evaporated in evaporator for absorbing energy of low-temperature source. Then, working medium is compressed in compressor and is fed to jet apparatus where it is mixed with liquid flow fed from separator mounted on condenser. Flow of working medium from jet apparatus is directed to condenser where it is cooled transferring heat to high-temperature receiver. EFFECT: enhanced power efficiency to reduced consumption of power. 12 cl, 2 dwg
