ABSTRACT:
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.
