  • Flight Instruments and Equipment (Aeroindustry)
CONT

Air-cycle refrigeration systems ... are used in many modern commercial aircraft for air-conditioning the cabin. ... The compressed air, when expanded in an expander turbine, drops enough in temperature to be used to chill the cabin air. Such a system for aircraft is effective and lightweight because it makes use of air already compressed by the power compressors.

DEF

Machine frigorifique utilisant la détente de l'air préalablement comprimé.

CONT

[...] Comprimé, [l'air] subit un refroidissement à pression constante, puis est détendu dans une machine à turbine [...] On utilise aussi la machine frigorifique à air pour le conditionnement d'air des avions, parce qu'elle est légère et compacte.

OBS

La distinction que le «Nouveau dictionnaire international du froid» (DIFRA) établit entre les termes «machine», «système» et «installation» est intéressante, mais la plupart des sources consultées les emploient l'un pour l'autre.
