<p>An air conditioning system, being powered by a supply (52) of compressed air, has an air cycle machine (12) which incorporates a regenerable filter (18). The filter (18) receives pressurized air for filtration from the air cycle machine compressor (30), and receives purge air from the air cycle machine turbine (32) downstream of a load heat exchanger (16). The air cools the load before purging the filter (18) thereby minimizing system power requirements.</p> |
