Description / Abstract:
This SAE Aerospace Information Report (AIR) covers the design
parameters for various methods of humidification applicable to
aircraft, the physiological aspects of low humidities, the possible
benefits of controlling cabin humidity, the penalties associated
with humidification, and the problems which must be solved for
practical aircraft humidification systems. The design information
is applicable to commercial and military aircraft. The
physiological aspects cover all aircraft environmental control
applications.
Purpose:
The purpose of this AIR is to provide guidelines for the design
of aircraft humidification systems. Physiological effects of
humidity levels on crew and passengers are reviewed. Various
techniques used for cabin humidification are discussed and
evaluated. Various technical issues are addressed, and effects
associated with humidification systems are described.
