<p>An air treating device (10) having a bellows box (12) in which is mounted a bellows compressor (13) formed of two spaced apart diaphragms (14, 141) having memory-shaped metal alloy elements embedded therein. The diaphragms (14, 141) are caused to contract and expand by slective heating of the memory-shaped metal alloy elements. The bellows compressor (13) is supported spaced in the bellos box (15) whereby air can flow through the box and as the bellows expand the air in the box (15) is cooled and expelled. As the diaphragms (14, 141) of the bellows compressor (13) contract, more air is sucked into the bellows box (15) and at the same time the refrigerant fluid inside the bellows is expelled into a condenser (26) where it is condensed to liquid. When the refrigerant liquid enters into the bellows it is vaporized and cools the bellows walls in their expanded state and the diaphragms (14, 141) act as a heat exchanger to cool air in said bellows box (15) and expel it therefrom.</p> |
