ABSTRACT:
An air cooling system is provided wherein a refrigerant gas, which may be air, is expanded in a plurality of piston and cylinder elements which are concurrently rotated by a power driven shaft. The reaction force of the expanding gas produces mechanical energy assisting in the rotation of the power shaft. Valving arrangements are provided for supplying pressured gas to separate sets of piston and cylinder elements in timed sequence, if desired. The expanded, cooled gas is directed through a heat exchanger mounted on the rotating power shaft and returned to a compressor, also mounted on the rotating power shaft, for recompression and resupply to the rotating piston and cylinder elements. Alternately, the cooled gas may be fed directly into the room to be cooled.
