An air cycle air conditioning system comprises a first air source for supplying cooling air and a second air source for supplying high temperature system air. The system further includes a device for transferring heat from the high temperature air and producing conditioned air having a temperature substantially lower than the high temperature system air. A mechanism for directing the conditioned air to the high temperature air prior to the high temperature air entering a component of the system for decreasing the temperature of the high temperature system air, prior to it contacting the system component is also provided. An air cycle air conditioning method comprises the steps of supplying cooling air and high temperature system air to a system component; transferring heat from the high temperature system air and producing conditioned air having a temperature substantially lower than the higher temperature system air; and mixing at least a portion of the conditioned air and the system air prior to its contact with the system component for decreasing the temperature of the high temperature air prior to reaching the system component.
