Introducción al Enfriamento Evaporativo
Evaporative cooling dates back more than 4,000 years to Egyptian slaves fanning large, porous jars of water to keep royalty cool. Archeological studies from approximately 1,000 B.C. provide evidence of circulating water from aqueducts through the walls of buildings to provide cooling for the wealthy Egyptians, Romans, and Greeks, while commoners hung wet mats over doors to allow the flow of air to cool living structures.
Fast forward to the late 19th century to find pioneers in what is now the southwestern United States hanging wet cloths over windows and doors to reduce the effects of high temperatures in the hot, desert climate. With the invention of electricity, wet bed sheets would be hung on porches where electric fans would pull air through the wet cloth to provide a natural cooling effect on hot summer nights.
In 1916, the first claim to an aspen pad cooler was made when Frank Tombs demonstrated a device in Phoenix, AZ that he claimed would reduce a room's temperature by 20 to 40 degrees through the evaporation of water in a forced draft. However, the greatest contribution to evaporative coolers was through brothers Adam, Gust, and William Goettl who, in 1939, opened Goettl Brothers Metal Products Company, Phoenix, AZ, with one of the first evaporative cooler patents, and began mass-producing evaporative coolers. In the years following, most residences and buildings in the hot, arid regions of the southwest U.S. relied on evaporative coolers as a source of cooling.
Although the principal of evaporative cooling today is the same as that dating back to the Goettl Brothers, the technology is far superior. The use of high-tech fluted media, surge pumps, thermostats, and low-voltage motors make today's evaporative cooler highly efficient, low maintenance, and an excellent cooling solution. And in this evolution of high-tech coolers, with the widest and most innovative product offering and services provided to distributors worldwide, Symphony is truly the world leader in evaporative cooling solutions.
