Do Freon gas leaks occur in Airplane conditioning systems as well? I was just reading about Aircraft Conditiong Systems and found that, the A.C. mechanism begins with compressor in the engine. Do these compressor also work the way in which AC/Refrigerator's compressor do? If they do, then Freon Gas Leaks should be something happening atleast once in a long period .. They are pretty common with household Air conditioning system.So, does this happens? I have never really heard of something like this happening to an aircraft..
Large aircraft use air conditioning packs (air-cycle machines) which uses only air, compressors and heat exchangers to cool/heat the air. There is no freon involved.
