La presente invención se refiere al campo de las tecnologías de limpieza y purificación de aire, particularmente de aquellas que son portátiles y que comprenden sistemas de ventilación para la eliminación de carga biológica, partículas en aire y compuestos volátiles. The present invention relates to the field of air purification and cleaning technologies, particularly those that are portable and that comprise ventilation systems for the removal of bioburden, airborne particles, and volatile compounds.
ANTECEDENTES BACKGROUND
Algunas enfermedades respiratorias se caracterizan por ser altamente contagiosas y causar daños graves a la salud e incluso la muerte. Estudios han mostrado que los virus que causan estás enfermedades son capaces de transportarse en gotículas suspendidas de hasta 2.5 pm de diámetro, conocidas como aerosoles, que pueden viajar en el aire por varios metros de distancia. Científicos reconocen dentro de esta categoría al COVID-19, enfermedad causada por el virus SARS-CoV-2 [Milton DK (2020); Nardell EA y Nathavitharana RR (2020); Tang S, et al (2020)]. Al mismo tiempo, en el aire pueden existir vahas clases de partículas sólidas conocidas como PM2.5 que también son peligrosas para la salud humana y que son responsables de alrededor de 7 millones de muertes en el mundo [https://www.who.int/data/gho/data/themes/topics/topic- details/GHO/ambient-air-pollution; Anenberg SC, et al. (2019); Wu X, et al. 2020]. Some respiratory diseases are characterized by being highly contagious and causing serious damage to health and even death. Studies have shown that the viruses that cause these diseases are capable of being transported in suspended droplets up to 2.5 pm in diameter, known as aerosols, which can travel in the air for several meters. Scientists recognize COVID-19, a disease caused by the SARS-CoV-2 virus, within this category [Milton DK (2020); Nardell EA and Nathavitharana RR (2020); Tang S, et al (2020)]. At the same time, various kinds of solid particles known as PM2.5 can exist in the air, which are also dangerous to human health and are responsible for around 7 million deaths worldwide [https://www.who. int/data/gho/data/themes/topics/topic-details/GHO/ambient-air-pollution; Anenberg SC, et al. (2019); WuX, et al. 2020].
La QMS (Organización Mundial de la Salud) y la CDC (Centers for Disease Control and Prevention) han reconocido que, para bajar los riesgos de contagio de este virus es necesario contar con tecnologías que comprenden un sistema de filtrado y purificación de aire, además de sistemas de ventilación natural o asistida que mantengan un ambiente más seguro en edificios y casas. Estas instituciones han emitido una serie de recomendaciones que comprenden la atención de las políticas de una institución especialista en HVAC (Heating, Ventilating and Air Conditioning) Por su parte, la ASHRAE (American Society of Heating, Refrigerating and Air- Conditioning Engineers) es la sociedad más prestigiosa y referente en estas cuestiones. Esta sociedad tiene vahos años emitiendo políticas y recomendaciones al respecto de la ventilación y limpieza de aire para edificios y casas. Dentro de las recomendaciones que la ASHRAE hace al respecto de la disminución del riesgo de contagio está el uso de filtros (MERV y HEPA) y lámparas UV-C para sistemas portátiles o centrales. The QMS (World Health Organization) and the CDC (Centers for Disease Control and Prevention) have recognized that, in order to lower the risks of contagion from this virus, it is necessary to have technologies that include an air filtering and purification system, as well as of natural or assisted ventilation systems that maintain a safer environment in buildings and houses. These institutions have issued a series of recommendations that include attention to the policies of an institution specializing in HVAC (Heating, Ventilating and Air Conditioning). For its part, the ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) is the most prestigious and benchmark society in these matters. This society has several years issuing policies and recommendations regarding ventilation and air cleaning for buildings and houses. Among the recommendations that ASHRAE makes regarding the reduction of the risk of contagion is the use of filters (MERV and HEPA) and UV-C lamps for portable or central systems.
Los virus y contaminantes transportados en el aire (biológicos, químicos y sólidos) pueden ser separados con relativa facilidad haciendo pasar el aire contaminado a través de medios filtrantes que sean capaces de retener los mencionados aerosoles, estos medios pueden ser los filtros tipo HEPA o MERV 13 (o superior). Existen otras tecnologías que auxilian en la desinfección del ambiente, como las lámparas de luz ultravioleta (UV) de 256 nm que permiten eliminar la carga biológica mediante diversos mecanismos asociados al contenido energético de esta radiación. Se ha demostrado que la radiación UV en la zona “C” es capaz de modificar el ADN y ARN de los virus de diversos tipos siempre y cuando la radiación y dosis sea la adecuada según el tipo de virus [Sabino CP, el al. (2020); Buonanno M, et al. (2020); Heilingloh CS, et al. (2020)]. Viruses and airborne contaminants (biological, chemical and solid) can be relatively easily separated by passing the contaminated air through filter media that are capable of retaining the aforementioned aerosols, these media can be HEPA or MERV type filters. 13 (or higher). There are other technologies that help disinfect the environment, such as 256 nm ultraviolet light (UV) lamps that allow the biological load to be eliminated through various mechanisms associated with the energy content of this radiation. It has been shown that UV radiation in zone "C" is capable of modifying the DNA and RNA of viruses of various types as long as the radiation and dose is adequate according to the type. of viruses [Sabino CP, al. (2020); Buonanno M, et al. (2020); Heilingloh CS, et al. (2020)].
Actualmente, la mayoría de los edificios y casas carecen de un sistema de ventilación con la capacidad de llevar a cabo la purificación y limpieza efectiva del aire en ambientes cerrados, lo que aumenta el riesgo de contagio de las enfermedades altamente contagiosas como el COVID- 19, en especial si en esos lugares se reúne un número considerable de personas y se carece de fuentes de ventilación naturales o artificiales. Ante esto, surge la necesidad de contar con equipos de filtración portátiles efectivos que incorporen un sistema para la purificación del aire, además de que posean otras características que permitan su funcionamiento en armonía con el espacio en el que se encuentren funcionando, que sean silenciosos y confortables. Currently, most buildings and houses lack a ventilation system with the capacity to carry out effective air purification and cleaning in closed environments, which increases the risk of contagion of highly contagious diseases such as COVID-19. , especially if such places gather a considerable number of people and there are no natural or artificial sources of ventilation. Given this, the need arises to have effective portable filtration equipment that incorporates a system for air purification, in addition to having other characteristics that allow its operation in harmony with the space in which it is operating, that are silent and comfortable.

A continuación, se analizan algunos documentos de patente relevantes, así como algunos productos disponibles en el mercado. In the state of the art there are some technologies that offer some of the benefits mentioned, although their main disadvantages are that they handle low air flows, not all of them integrate UVC lamps and those that do have very low capacity and their positioning reduces their effectiveness. Some relevant patent documents as well as some products available on the market are discussed below.
