ABSTRACT:
An air conditioner comprises a compressing and expanding apparatus which includes a compressing system for compressing air taken into compression chambers in one of two cylinder blocks through an inlet aperture and discharging the air from an outlet aperture, and an expanding system for taking in the compressed air through an entrance aperture into expansion chambers in the other cylinder block and expanding the air therein. The air conditioner further comprises a heat exchanger for cooling positioned in the air flow between an outlet aperture of the compressing system and an entrance aperture of the expanding system. Since air is utilized as the cooling medium for the air conditioner, no air pollution or other problem is caused even if it is released into the atmosphere. Moreover, since multiple chambers are provided to process a large amount of air and since the compressing system and the expanding system are arranged compactly, the compressing and expanding apparatus can be compact.
