Abstract
Abstract Apparatus for supplying a controlled atmosphere to a closed chamber. An ultrasonic nebulizer generates liquid particles and the particles are dispersed in air, or in a filtered air-gas mixture, to increase its specific heat. The resulting mixture is then passed through a temperature controlled heat exchanger and into the chamber.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
156 words
Apparatus for supplying a temperature and humidity controlled environment to an enclosed space, comprising, in combination: means for supplying filtered air under pressure to said space, a reservoir containing a liquid, an ultrasonic nebulizer for dispersing particles of the liquid into the filtered air, whereby the specific heat of the air-liquid particle mixture is such that a desired temperature can be maintained in such space without recirculation of air from such space, a heat exchanger positioned downstream from said ultrasonic nebulizer for changing the temperature of the dispersed liquid particles and filtered air, means operatively connected to said ultrasonic nebulizer and said heat exchanger for sensing and controlling the temperature and relative humidity conditions within such space, conduit means for carrying the dispersed liquid particles and filtered air from said heat exchanger to such space, and means for discharging such mixture from such space to atmosphere whereby the mixture is not recirculated through such enclosed space.
Claim 2
Dependent Claim
156 words
Apparatus for supplying a temperature and humidity controlled environment to an enclosed space, comprising, in combination: means for supplying filtered air under pressure to said space, a reservoir containing a liquid, an ultrasonic nebulizer for dispersing particles of the liquid into the filtered air, whereby the specific heat of the air-liquid particle mixture is such that a desired temperature can be maintained in such space without recirculation of air from such space, a heat exchanger positioned downstream from said ultrasonic nebulizer for changing the temperature of the dispersed liquid particles and filtered air, means operatively connected to said ultrasonic nebulizer and said heat exchanger for sensing and controlling the temperature and relative humidity conditions within such space, conduit means for carrying the dispersed liquid particles and filtered air from said heat exchanger to such space, and means for discharging such mixture from such space to atmosphere whereby the mixture is not recirculated through such enclosed space.
Claim 3
Dependent Claim
32 words
The apparatus of claim 1, including: means for supplying compressed oxygen, and means for controllably mixing the oxygen with the filtered air prior to dispersing the liquid particles into the filtered air.
Claim 4
Dependent Claim
184 words
Apparatus for supplying a controlled environment to an enclosed space comprising, in combination, blower means for supplying air under pressure, a nebulizer for dispersing liquid particles having a mass means size of between 1 and 6 microns into the air discharged from said blower means, whereby the specific heat of the air-liquid particle mixture is such that a desired temperature can be maintained in such space without recirculation of air from such space, heat exchanger means positioned downstream from said nebulizer for changing the temperature of the air-particle mixture, means operatively connected to said heat exchanger means for sensing and controlling the temperature within such space, said sensing and controlling means including temperature-sensing means operatively connected to said heat exchanger means, means for supplying a cooling fluid to said heat exchanger means, means for supplying a heating fluid to said heat exchanger means, a temperature control means for controlling the flow of said cooling fluid and said heating fluid to said heat exchanger, and means for discharging such mixture from such space to atmosphere whereby such mixture is not recirculated through such enclosed space.
