passenger air condition kit或者pneumatic air cycle kit两个说法都有
维基百科上时这么说的
The equipment is referred to variously as PAC, air conditioning pack, or A/C pack, but there is a lack of consistency and agreement as to the derivations and meanings:
Pack. as an abbreviation of package, applied to both pneumatic and non-pneumatic systems (Boeing, Airbus, Embraer, Bombardier and Lockheed)
PAC as an acronym meaning either Passenger Air Conditioning or pneumatic air conditioning (the latter being found on systems control panels of at least one business jet supplier)
PACK as an acronym for pneumatic air cycle kit
