Zusammenfassung:	An environmental control system includes an airflow source (14), and an air cycle machine (22) in flow communication with the airflow source, and through which an airflow from the airflow source is directed. The air cycle machine includes a compressor (30) and a turbine (46). A liquid load heat exchanger (66) is located in flow communication with the turbine such that airflow downstream of the turbine exchanges thermal energy with a liquid flow at the liquid load heat exchanger to cool the liquid flow. A liquid load reheater (56) is located upstream of the turbine and upstream of the liquid load heat exchanger. The liquid load reheater is configured such that a thermal energy exchange between the airflow prior to the airflow entering the turbine and the liquid flow prior to the liquid flow entering the liquid load heat exchanger occurs at the liquid load reheater.
