Abstract
An environmental control system of an aircraft includes a primary heat exchanger, a secondary heat exchanger and an air cycle machine. The air cycle machine includes a compressor fluidly coupled to an outlet of the primary heat exchanger and an inlet of the secondary heat exchanger, a dehumidification system arranged in fluid communication with the outlet of the secondary heat exchanger, a first turbine fluidly coupled to an outlet of the secondary heat exchanger and optionally a second turbine disposed downstream of the first turbine that receives air from the first turbine in a normal mode a first humidity sensor disposed fluidly between the first turbine and the second turbine that measures humidity of air that has left the first turbine as it enters the second turbine in the normal mode.
