FIELD: engines and pumps.
SUBSTANCE: system comprises the first compressor (6a) to expose air to the first compression stage, the second compressor (6b) to expose air to the second compression stage, the first cooling system with a circulating coolant and the second cooling system with a circulating coolant, which has lower temperature compared to the coolant in the first cooling system. The system comprises the first cooler (9a) of supplied air arranged between the first compressor (6a) and the second compressor (6b) and cooled with the help of the coolant from the second cooling system, the second cooler (9b) of supplied air arranged downstream the second compressor (6b) and cooled with the help of the coolant from the first cooling system, and the third cooler (9c) of supplied air arranged downstream the second cooler (9b) of supplied air and cooled with the help of the coolant from the second cooling system.
EFFECT: increased efficiency of compressed air cooling.
