FIELD: transport.
SUBSTANCE: invention relates to aircraft air conditioning. Proposed system comprises air source 12, air pipeline 22-30 incorporating main valve 16 and air conditioning unit 32. Bypass pipeline 36-50, 58, 60 is arranged between source 12 and air conditioning unit 32 to comprise bypass valve 34 and bypass air pipeline section 22-26, 16 that makes second air system section made partially independent of air conditioning system. Air mass flow fed from source 12 via pipeline 22-30 into air conditioning unit 21 is adjusted by main valve 16.
EFFECT: reliable operation.
