Finally, there seems to be a solution on the market, at least for commercial construction. Advantix Systems has developed a liquid dessicant system that first pulls the excess moisture out of the air, and then cools it to the right temperature. This is considerably more efficient that traditional AC technology, which is based on the principle of cooling air to the dewpoint in order to draw off the condensed moisture. This overcooled air is then re-heated to a more comfortable temperature. The Advantix technology pulls air through a strong brine solution which absorbs the excess moisture. This brine water-filter also serves to clean the air of particulates larger than 5 microns, which covers most mold spores, pollen, and dust, but not smoke or insecticide. For the engineering type, the Advantix website has a detailed schematic diagram, and for the rest of us, there is a very nifty video explaining the basic science of absorption and diffusion. The website also provide the calculations behind their energy saving claims, and a mention of “competitive pricing.” A few of the case studies offered projected savings, which will hopefully be updated with actual performance numbers and payback periods as these figures become available. Overall, I appreciate the transparency of information on the website.
This technology was initially developed to manage the air conditions of ice-skating. The company is relatively new on American shores, but the USA President, Ms. Hannah Granade was named “Most Creative People in Business” in 2012 by Fast Company. Certainly, Advantix is a company worth watching, and we can only hope that they will scale their product to residential size in the near future.
