An air cycle air conditioning system (10) for rgulating the temperature and pressure of diverse loads includes open and closed loop sections (12) and (16). A first load (14) requiring heating or cooling with constantly supplied fresh air is provided with chilled air from first turbine (75) and warm air from first bypass valve (50). A second load (20) which can be heated or cooled with a supply of recirculating air is provided with chilled air from second turbine (130) and warm air from a second bypass valve (170). Air is supplied to the second turbine from a compressor driven by the first turbine whereby the first turbine maintains the temperature of both loads either by the direct supply of air thereto or by driving another turbo-compressor system. |
