FIELD: conditioning systems. SUBSTANCE: system consists of an open-loop air line which includes successively connected engine compressors 4, heat exchanger 3, and flying vehicle pressure cabin 5; and a closed-loop air line which includes successively connected pressure cabin 5, fan, and heat exchanger 2. A cooling loop is integrated in the system. The cooling loop consists of successively mounted thermally insulated tank 1 containing a liquified supercooled hydrocarbon, such as propane, heat exchangers 2, 3, and engines which burn the used propane. EFFECT: increased efficiency of operation, reduced mass of the system. 1 dwg
