Now that the heat of summer squeezes, you want a good drink of fresh water. But did you know that one of the most primitive water cooling systems, the botijo, uses the same principle as the most modern cooling towers or cooling towers?
Yes, both mechanisms are based on evaporative cooling, so the simple botijo of the town and the more sophisticated cooling towers have a common origin. The botijo is a porous clay vessel, and its main function is to keep the water cool compared to the outside temperature. In fact, a botijo can lower the temperature of the water up to ten degrees less than the ambient temperature, and can do it in less than an hour, and without using any type of external energy. This is possible thanks to the porosity of its surface.
It is a simple physical process: water needs energy to go from liquid to gaseous state (that is, to evaporate), and this energy contribution can be made by the environment or by the system itself that is in action (that is, the Water). That is why, when evaporating, water extracts the necessary energy from the water’s own temperature, and water, therefore, goes down.
The porosity of the botijo surface allows these evaporated molecules to escape, and therefore the process does not stagnate, re-heating the water. For this it is necessary that there be an air current, better dry and hot, that this steam is carried. That is why botijos are usually left outside the rooms: at the door of the houses, for example.
The principle of evaporation is used in many cultures to cool water, food and environments, and currently has applications in industrial refrigeration. In Control y Ventilación, S.L. we are experts in evaporative cooling, and we want to wish you a happy and fresh summer.
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 .
