| 摘要 |
A system for simply controlling the moisture content of gases, such as air, by use of a hydroscopic medium which is subject to regeneration characterized by the combination of (a) means for maintaining constant temperature of the medium in the regeneration zone, (b) a liquid level controller for maintaining constant liquid level in the regeneration zone, and (c) a density controller system sensitive to changes of liquid density of the circulating medium, units (b) and (c) serving to add additional quantities of hydroscopic medium to the regeneration zone upon a drop in liquid level therein, and/or concentration of the circulating medium.
