A cooling system is simple in structure, efficient, and durable due to a lowered burden on bearings and reduced loss of drive power. The cooling system includes a compressor having a first rotor for compressing air, a cooler for cooling high-temperature, high-pressure air delivered form the compressor, and an expander having a second rotor for effecting adiabatic expansion of air cooled by the cooler. The expander has a speed change mechanism for transmitting drive torque of a prime mover to the compressor and a common shaft that extends through the first and second rotors. The expander is interposed between the speed change mechanism and the compressor.
