초록 ▼

A system for conditioning working fluid in environmental control systems includes arrangements for minimizing icing from a variable flow velocity turbine exit flow at subfreezing conditions, wherein the turbine is very closely located to the downstream heat exchanger, including a backpressure plate for minimizing flow velocity stratification, an internal bypass passage arranged to produce a relatively predictable bypass flow ratio regardless of the flow velocity stratification, and other anti-icing techniques.

대표청구항 ▼

A system for conditioning a working fluid to be distributed from a source thereof to a point of use, comprising: an air cycle machine including a compressor mechanically driven by a turbine, said compressor receiving working fluid from said source and operable to compress and heat the working fluid, said turbine operable to expand and cool the working fluid to subfreezing conditions prior to its delivery to the point of use; first means for receiving and further cooling the working fluid discharged from said first means; condenser heat exchange means, receiving working fluid discharged from said reheater means, for condensing vapor entrained in the working fluid, said condenser means receiving the subfreezing working fluid discharged from said turbine to effect said condensing; separator means, receiving the working fluid and condensed vapor discharged from said condenser means, for separating and removing the condensed vapor from the working fluid, at least a portion of the working fluid discharged from said separator means being directed through said reheater means to effect said further cooling of the working fluid discharged from said first means, and substantially all of the working fluid discharged from the separator means being delivered to said turbine; a hot air passage extending from a location upstream of said compressor to a second location downstream of said condenser heat exchange means; control means at said second location for controlling the ratio of cold air from said turbine and hot air from said hot air passage to be delivered to the point of use, whereby substantially only the cold air portion of working fluid delivered to the point of use passes through said turbine and said condenser heat exchange means; said condenser heat exchange means defining a core having first and second passageways arranged for heat exchange between the fluids therein, and further including: first inlet and outlet plenum chambers at opposite inlet and outlet faces of said core, said first inlet and outlet plenum chambers communicating with said first passageway, said first inlet plenum chamber receiving the subfreezing working fluid discharged from said turbine and being sufficiently close-coupled to said turbine to produce a substantial stratification of flow velocity of he subfreezing working fluid impinging upon aid inlet face of the core, said first outlet plenum chamber receiving and collecting the working fluid discharged from the first passageway for delivery thereof to said control means; second inlet and outlet plenum chambers communicating with said second passageway, said second inlet plenum chamber receiving the working fluid discharged from said reheater means, and said second outlet plenum chamber receiving and collecting the working fluid discharged from said second passageway for delivery thereof to said separator means; and a thin, solid plate disposed in said first outlet plenum chamber in a position spaced slightly from said outlet face.
