COMBINED SYSTEM AND METHOD OF HEAT RECOVERY AND COOLING Russian patent published in 2020 - IPC F25B9/00 F01K25/10 F25B11/02 

FIELD: machine building.

SUBSTANCE: combined thermodynamic system (101) uses the removed heat from the exhaust gas of primary engine (162) for generating mechanical energy, which ensures operation of refrigerating circuit (105). System comprises power generating circuit (103) configured to circulate first flow of working fluid medium and to generate mechanical energy therefrom. Combined thermodynamic system (1) additionally comprises refrigerating circuit (105) containing refrigerating compressor (117), actuated by mechanical energy generated by power generating circuit (103), and configured to circulate second flow of said working fluid in refrigerating circuit (105). Cooling circuit (105) is configured to remove heat from process gas treated by process gas compressor (160).

EFFECT: technical result is reduction of power consumption increasing efficiency while maintaining power of gas turbine at constant level.
