The invention provides an air cycle machine, an aircraft air conditioner and an aircraft, the air cycle machine comprises an expansion part, the expansion part comprises a temperature control shell and a turbine located in a containing cavity of the temperature control shell, and the temperature control shell is provided with an air supply duct communicating with the containing cavity and a high-temperature air inlet communicating with the air supply duct; a stirring and flow mixing assembly is further arranged in the air supply duct and located on the side, away from the expansion part, of the high-temperature air inlet, and the stirring and flow mixing assembly comprises a stirring impeller used for stirring and mixing air flowing through the stirring impeller; a temperature detection head of the temperature detection part is located in the air supply duct and located on the side, away from the expansion part, of the stirring impeller. The stirring impeller is used for achieving full mixing of high-temperature airflow and low-temperature airflow in the air supply duct, the temperature of the airflow flowing through the air supply duct is more uniform, the detected real-time temperature is more accurate, then it can be guaranteed that the temperature of the airflow sent out by the air supply duct is closer to a temperature control target value, and therefore the comfort of the air conditioner is improved.
本发明提供一种空气循环机、飞机空调及飞机,其中空气循环机,包括:膨胀部,膨胀部包括温控外壳以及处于温控外壳的容置腔内的涡轮,温控外壳具有与容置腔连通的送风风道以及与送风风道连通的高温空气进口;送风风道内还设有搅拌混流组件,且搅拌混流组件处于高温空气进口远离膨胀部的一侧,搅拌混流组件包括搅拌叶轮,用于搅拌混合流经其的空气;温度检测部件,其温度检测头处于送风风道内,且处于搅拌叶轮远离膨胀部的一侧。本发明利用搅拌叶轮实现对送风风道内的高低温气流的充分混合,送风风道内流经的气流温度更加均匀,检测到的实时温度更加准确,进而能够保证送风风道送出的气流温度与温度控制目标值更加接近,从而提升了空调舒适性。
