Method for drying compressed gas by means of a drying device with an inlet for the compressed gas to be dried and an outlet for the dried compressed gas. The drying device includes at least two vessels filled with a regenerable desiccant and an adjustable valve system including a first valve block and a second valve block that connects the inlet, respectively outlet, to the vessels. The adjustable valve system is being regulated as such that at least one vessel will dry compressed gas, while the other vessel will be regenerated and cooled successively, wherein by regulation of the valve system the vessels will each in turn dry compressed gas. The method includes calculating the time period (t.sub.ads) during which a vessel (2) dries compressed gas, calculated on the basis of a (t.sub.ads) formula t.sub.ads=A*B.

A dry gas scrubber is disclosed. The dry gas scrubber is for treatment of an effluent stream and comprises: a chamber having an inlet for receiving the effluent stream, a cooler coupled with the inlet and configured to cool the effluent stream, and a resin chamber downstream of the cooler and configured to receive the effluent stream for treatment. In this way, the cooler is interposed between the process tool and the resin chamber and operates to cool the effluent stream prior to its being delivered to the resin chamber. Cooling the effluent stream in this way helps to improve the performance of the resin, even when the effluent stream is at an elevated temperature.

In one embodiment, a method for decreasing a humidity level in an information handling system includes: receiving, by a sound field chamber, an incoming airflow, the incoming airflow having a humidity level corresponding to an amount of water vapor in the incoming airflow; identifying, by a humidity controller, the humidity level of the incoming airflow; determining, by the humidity controller, that the humidity level is greater than a threshold humidity level; and in response to determining that the humidity level is greater than the threshold humidity level: causing, by the humidity controller, a sound source of the information handling system to generate a sound field within the sound field chamber, the sound field comprised of sound waves, the sound waves causing an acoustic agglomeration of the water vapor, the acoustic agglomeration causing the humidity level to decrease.

Atmospheric moisture harvester systems include two beds with water capture material, such as metal-organic framework (MOF), a heater, two fans, and a condenser having two sides, operatively configured into adsorption and desorption modes, wherein the MOF beds are interchangeable to cycle between the desorption and water adsorption modes. The systems may further include a photovoltaic panel powering the fans and condenser.

A compressed air drying system is provided for removing moisture from compressed air. The dryer operates in two modes in response to the demand for compressed air. In a first mode of operation, a refrigeration compressor runs continuously and the speed of a condenser fan is varied to maintain a constant cooling temperature. In a second mode of operation, the refrigeration compressor runs intermittently between on and off periods. As result, the cooling temperature fluctuates during the second mode of operation.

There is accordingly provided a device for measuring a person's ventilation including oxygen consumption. The device includes a breathing conduit with at least one sensor sampling port. The device includes a dehumidification conduit extending from the sensor sampling port towards a sensor. The dehumidification conduit has a proximal end portion flush with the sensor sampling port. The dehumidification conduit has a longitudinal axis about which the proximal end portion thereof extends. The breathing conduit is shaped to promote a flow of air adjacent the sensor sampling port in one or more directions perpendicular to the longitudinal axis.

An atmospheric water generation system comprises water vapor consolidation systems configured to increase the relative humidity of a controlled air stream prior to condensing water from the controlled air stream. The water vapor consolidation system comprises a fluid-desiccant flow system configured to decrease the temperature of the desiccant to encourage water vapor to be absorbed by the desiccant from an atmospheric air flow. The desiccant flow is then heated to encourage water vapor evaporation from the desiccant flow into a controlled air stream that circulates within the system. The humidity of the controlled air stream is thereby increased above the relative humidity of the atmospheric air to facilitate condensation of the water vapor into usable liquid water.
