FIELD: ventilation.
SUBSTANCE: invention relates to aircraft protective equipment ventilation system. Ventilation system of pilot protective equipment of air conditioning system of aircraft (AC) includes hot line (5) connected to SCR hot line, first cold line (9) connected to cold line of SCR after turbo-cooler (4), second cold line (10) connected to cold line of SCR to turbine-cooler (4), excess pressure regulators (EPR) installed on hot line and second cold line (10), mixer-ejector (8). Hot and second cold lines are connected to inlet nozzles of mixer-ejector. First cold line (9) is connected to protective equipment. Output of mixer-ejector (8) is connected to the first cold line (9) with formation of ejector.
EFFECT: wider range of controlling temperatures of the air supplied to the protective equipment, particularly obtaining a lower temperature thereof compared to the existing system.
