Evaporative cooling: origins, development and benefits
In the article he describes the origins by commenting on how the first evaporative cooling systems appeared in the 1930s, it was an artisanal system that consisted of hanging damp cloths from the windows so that the fans pushed the wet air inside. Later, systems were installed in which the cloth was replaced by straw or wood fiber and the fan was enclosed in a box.
The system stands out for working using the circulating air, keeping doors open, at the same time that it eliminates traces of dust or other substances, and therefore its benefits stand out, among which it is described that it can work in open spaces and with open windows, being green by not using refrigerant while saving energy.
Control y Ventilacion, S.L. is a company of international renown within the industrial and livestock sector, for being a manufacturer of products within the evaporative cooling sector, such as the HUMIBAT, evaporative plastic cooler; or its NUCLEOS towers, Cooling Towers. In both products, the substrate in which the evaporative process is produced is a plastic honeycomb, a honeycomb resistant both to physical and chemical attacks, and at the same time flexible, a honeycomb with a mesh structure, made of polyethylene High Density, and marketed under the names of PANAL C & V or in the case of being a drop separator, SEPARADOR C & V .
