FIELD: heating engineering, particularly heat pumps and domestic and industrial cooling plants. ^ SUBSTANCE: method involves simultaneously performing isothermal compression and adiabatic expansion of different working body portion parts with following pressure recovery to initial value in heating and cooling heat-exchangers. Heterogeneous working body supplied as foamed neutral liquid provided with foaming additives and inert gas, is compressed. Then the working body is separated into liquid and gaseous fractions, which are separately throttled and expanded correspondingly. After that the fractions are separately supplied into parallel heating and cooling heat-exchangers with following mixing thereof and foam generation. Device comprises working body circulation loops provided with compressor, throttle and cooling and heating heat-exchangers. Compressor outlet is connected with tangential connection pipe of separator. Upper connection pipe of separator is linked to expander inlet. Lower connection pipe thereof is attached to throttle, which in turn is connected with inlet nozzle of injector included in inlet connection pipe of compressor through heating heat-exchanger. Side connection pipe of injector is communicated with expander outlet through cooling heat-exchanger. The expander is mechanically or electrically linked to compressor drive. ^ EFFECT: decreased pressure in cooling and heating heat-exchangers to compressor pressure level and increased ecological safety. ^ 5 cl, 3 dwg |
