High-temperature sterilization air conditioning system for airplane and sterilization method

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 (), a heater (), a high-temperature injection mixing chamber () and a primary heat exchanger () bypass. The recirculated airline is connected to the high-temperature injection mixing chamber (). After being mixed with high-temperature engine bleed air (I) under the injection action of an injector (), the mixed high-temperature gas enters a compressor () through the primary heat exchanger () bypass to be compressed and heated, is regulated to a suitable temperature through cooling of a secondary heat exchanger () and a turbine (), 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, and thereby achieving the effects of killing the infectious viruses and inhibiting cross infection among people.
