Abstract: An air treating device having a bellows box in which is mounted a bellows compressor formed of two spaced apart diaphragms having memory-shaped metal alloy elements embedded therein. The diaphragms are caused to contract and expand by selective heating of the memory-shaped metal alloy elements. The bellows compressor is supported spaced in the bellows box whereby air can flow through the box and as the bellows expand the air in the box is cooled and expelled. As the diaphragms of the bellows compressor contract, more air is sucked into the bellows box and at the same time the refrigerant fluid inside the bellows is expelled into a condenser 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 act as a heat exchanger to cool air in said bellows box and expel it therefrom.

Abstract: An environmental control system which atomizes filtered and purified or pretreated water introduced at high pressures through a plurality of spaced nozzles which have orifices having a diameter of about 10 microns to produce a mist of microscopic particles which evaporate at elevated temperatures by flash evaporation to produce a significant cooling effect. At normal temperatures cooling is minimal but humidification is obtained. The nozzles which may be especially designed to eliminate or minimize clogging of the orifices are installed in elongated pipes or conduits at selected intervals either in a single line or alternatively in a dual line of parallel pipes spaced one above or in front of the other with the nozzles arranged in a staggered manner so that the effluent spray is from the upper pipe and is not ejected above the spray from the lower pipe. Additionally, the pipes are positioned so that the ejection of spray from the nozzles can occur at angles which will provide an optimum spray pattern.
