1. An aircraft Ultra-High-Temperature Sterilization Air Conditioning System (UHTS-ACS), wherein an ultra-high-temperature sterilization recirculated air device is added on the basis of a traditional aircraft air conditioning system, and the ultra-high-temperature sterilization recirculated air device comprises an ultra-high-temperature sterilization recirculated air duct,
a heater,
a high-temperature injection mixing chamber, and
a primary heat exchanger bypass;
wherein
the ultra-high-temperature sterilization recirculated air duct is connected to a recirculated air main line in the traditional aircraft air conditioning system;
the ultra-high-temperature sterilization recirculated air duct is connected to the high-temperature injection mixing chamber,
so that ultra-high-temperature sterilization recirculated air, after being preheated by the heater, is then mixed with high-temperature engine bleed air in the high-temperature injection mixing chamber, and
the mixed high-temperature gas enters a compressor through the primary heat exchanger bypass to be compressed and heated, is subsequently cooled by a secondary heat exchanger and a turbine to a suitable temperature, and then is supplied to an aircraft cabin.
