An environmental control system includes a primary heat exchanger (202) operable to transfer heat from an air source (204) to a refrigerant (206) in a generator flow (208) and output an air flow (210). An ejector (212) is operable to produce an intermediate refrigerant flow (214) based on receiving the generator flow as a motive fluid and drawing a vapor refrigerant flow (216) as a suction fluid. A refrigerant condenser (220) is operable to convert the intermediate refrigerant flow to a liquid refrigerant flow (222). A pump (242) is operable to provide the refrigerant to the primary heat exchanger from a portion of the liquid refrigerant flow. An expansion device (240) is operable to expand the liquid refrigerant flow prior to entering an evaporator. The evaporator is operable to convert the liquid refrigerant flow to the vapor refrigerant flow and produce a cooled evaporator air flow output based on the air flow.
