Air is extracted from a pressurized air source. An air-to-air heat exchanger (115) receives and cools the extracted pressurized air. Further, an expansion turbine (130) receives at least a portion of the cooled pressurized air from the air-to-air heat exchanger and expands the cooled pressurized air into chilled air while extracting work. An air-to-coolant heat exchanger (120) receives the chilled air from the expansion turbine which is used to chill refrigerant coolant. The air-to-air heat exchanger (115) also receives the chilled air reclaimed from the air-to-coolant heat exchanger (120), subsequent to chilling the refrigerant coolant, to cool the air extracted from the pressurized air source. In one embodiment, the extracted work is used to drive a generator (135) to supply electricity to a distribution system.
