FIELD: aircraft air conditioning systems.
SUBSTANCE: air conditioning system for supersonic civil aircraft comprises sequentially located air preparation system, an air cooling unit (ACU) and an air recirculation system. Air preparation system includes electric supercharger (KM1,2) with cooling of electric motor and its fuel control system, air-to-air heat exchanger (AT), electric fan (EV1,2), air flow sensor (DRP1,2), bypass flaps and check valves (KO1,2,3,4). Air cooling unit consists of: turbo-cooler with turbine controlled nozzle assembly, unit of fuel-air heat exchangers, unit of loop air-to-air heat exchangers, moisture separator, located before turbo-cooler turbine stage, bypass flaps and air flow control. Air recirculation system includes fan with controlled rotation frequency.
EFFECT: improving energy efficiency.
