AbstractAn air-conditioning system being powered by a supply of compressed air, has an air cycle machine which incorporates a filter. The filter receives pressurized air for filtration after said air has passed through a heater which optimizes the temperature and humidity of the air and passes through a second reheater downstream of the filter and upstream of the turbine to maximize the efficiency of the turbine.
