ABSTRACT:
An air cycle air conditioning system has an air expansion turbine arranged to deliver air through an outlet formed by a wall having an outer surface that defines in part passage means through which supply air flows to the turbine. Heat flow from the supply air into the wall prevents formation of ice in the outlet so that in at least one phase of system operation the turbine delivers air at sub-zero temperature with which large quantities of augmenting air can be mixed so as to increase the system cooling capacity.
