Abstract

An aircraft Ultra-High-Temperature Sterilization Air Conditioning System (UHTS-ACS) and a sterilization method are provided. An ultra-high-temperature sterilization recirculated air device is added on the basis of a traditional aircraft air conditioning system. The recirculated air device includes an ultra-high-temperature sterilization recirculated airline (9), a heater (26), a high-temperature injection mixing chamber (27) and a primary heat exchanger (12) bypass. The recirculated airline is connected to the high-temperature injection mixing chamber (27). After being mixed with high-temperature engine bleed air (I) under the injection action of an injector (28), the mixed high-temperature gas enters a compressor (15) through the primary heat exchanger (12) bypass to be compressed and heated, is regulated to a suitable temperature through cooling of a secondary heat exchanger (13) and a turbine (16), and then is supplied to an aircraft cabin. The system and method can perform ultra-high-temperature sterilization on the recirculated air of the aircraft air conditioning system, thus ensuring the cleanliness of the aircraft cabin supply air and the hygiene safety of people on board, …
