FIELD: aeronautical engineering. SUBSTANCE: air-conditioning system has inlet, outlet and bypass mains, flow regulator with two dampers fitted in inlet and bypass mains, two heat exchangers cooled with atmospheric air with compressor mounted between them which is mechanically linked with turbine of turbocooler by means of common shaft. System is provided with additional main connecting the inlet and outlet of compressor. Additional main is provided with check valve. Inlet bypass main provided with damper of flow regulator is brought in communication with outlet of heat exchanger mounted after compressor; outlet of bypass main is connected with outlet main. EFFECT: enhanced efficiency at reduced inlet pressure of air being cooled due to use of efficiency of cooling of heat exchanger mounted after compressor.
