En un segundo aspecto, la invención se refiere a un enfriador evaporativo que permite, además de refrescar el aire dirigido hacia un ambiente interior, higienizar éste mediante el citado procedimiento basado en el uso de agua ozonificada.In a second aspect, the invention refers to an evaporative cooler that allows, in addition to cooling the air directed towards an indoor environment, to sanitize it by means of the aforementioned procedure based on the use of ozonated water.

Son conocidos en la técnica métodos y dispositivos para refrigerar el interior de cualquier habitáculo. En particular, la tecnología de enfriamiento evaporativo se basa en emplear la entalpía de vaporización del agua para reducir la temperatura del aire seco y caliente exterior mediante su contacto con agua y la consecuente transferencia de calor entre ambos, dando como resultado un aumento de la humedad y una disminución de la temperatura del aire que entra en el ambiente interior. Este intercambio adiabático se lleva a cabo en un panel filtrante saturado de agua presente en el dispositivo de enfriamiento evaporativo.Methods and devices for cooling the interior of any cabin are known in the art. In particular, evaporative cooling technology is based on using the enthalpy of vaporization of water to reduce the temperature of the dry and hot outdoor air through its contact with water and the consequent transfer of heat between the two, resulting in an increase in humidity. and a decrease in the temperature of the air entering the indoor environment. This adiabatic exchange is carried out in a filter panel saturated with water present in the evaporative cooling device.

Utilizando este tipo de tecnologías, y de acuerdo con el primer aspecto, la presente invención proporciona un procedimiento para la higienización de ambientes interiores mediante instalaciones de enfriadores evaporativos donde el agua que entra en contacto con el aire caliente y seco en el panel filtrante se ha tratado previamente con ozono mediante un ozonizador.Using this type of technology, and in accordance with the first aspect, the present invention provides a procedure for the sanitization of indoor environments by means of evaporative coolers installations where the water that comes into contact with the hot and dry air in the filter panel has been pretreated with ozone by means of an ozonator.

A este respecto, el ozono disuelto en el agua comienza su proceso de decaimiento y forma radicales hidroxilo (HO ), que reaccionan con los microorganismos presentes en el aire seco para inactivarlos mediante una fuerte oxidación que da como resultado oxígeno, agua y microorganismos inactivos.In this regard, ozone dissolved in water begins its decay process and forms hydroxyl radicals (HO), which react with microorganisms present in dry air to inactivate them through strong oxidation resulting in oxygen, water and inactive microorganisms.

Así, el procedimiento de la invención incluye una etapa de ozonización del agua de entrada al enfriador evaporativo de forma que, tras el intercambio de calor entre el aire caliente y seco del exterior y el agua ozonificada, el aire húmero, fresco y tratado con ozono circula hacia el ambiente interior higienizando dicho ambiente interior, además de refrescándolo y aportándole humedad. De acuerdo con la invención, esta etapa de ozonización del agua se lleva a cabo antes de su contacto con el aire exterior en el panel filtrante evaporativo.Thus, the process of the invention includes a step of ozonation of the water entering the evaporative cooler so that, after the heat exchange between the hot and dry air from outside and the ozonated water, the humid, fresh air treated with ozone it circulates towards the interior environment sanitizing said interior environment, in addition to refreshing it and providing it with humidity. According to the invention, this step of Ozonation of the water is carried out before its contact with the outside air in the evaporative filter panel.

El enfriador evaporativo de la invención incluye así un ozonizador dispuesto antes del panel filtrante y tras la entrada de agua de la red de suministro que aporta agua ozonificada para la transferencia de calor entre este agua ozonificada y el aire exterior. The evaporative cooler of the invention thus includes an ozonator arranged before the filter panel and after the entry of water from the supply network that provides ozonated water for the transfer of heat between this ozonated water and the outside air.

Mediante la adecuada regulación del ozonificador, se consigue la ozonización en un nivel adecuado para conseguir la óptima desinfección del aire y, consecuentemente, del ambiente de los diferentes ambientes interiores asistidos por el procedimiento y el enfriador evaporativo de la invención.Through proper regulation of the ozonator, ozonation is achieved at an adequate level to achieve optimum disinfection of the air and, consequently, of the environment of the different indoor environments assisted by the method and the evaporative cooler of the invention.
