Abstract
The system consists in the installation of a set of condensation control elements located in the back and lower part in the outer condensing units of air conditioning systems and is used for eliminating by evaporation the liquid produced in the conditioning process. The system is formed by an electric liquid-level detector connected to the container for collecting liquids in the base of the outer condensing equipment and which, depending on the water level in the container, activates the impulsion pump which raises the water to conduits fastened to the back ventilation grille which is discharged, by sprinklers located in the ends thereof, onto the condenser, thereby evaporating the condensed liquid and removing the necessity of installing pipes to drain away condensates and improving thermal performance since the unit is cooled by the ventilation grille of the condensing unit.

ANTECEDENTES DE LA INVENCIÓN.BACKGROUND OF THE INVENTION
Hoy en día el acondicionamiento de aire es el proceso más completo de tratamiento del aire ambiente, consistente en regular las
condiciones en cuanto a temperatura (calefacción o refrigeración), humedad y calidad (renovación, filtrado).Nowadays air conditioning is the most complete process of ambient air treatment, consisting of regulating the conditions regarding temperature (heating or cooling), humidity and quality (renewal, filtering).
En los últimos años, Ia implantación de dispositivos acondicionadpres de aire se ha convertido en una necesidad, imprescindible para lograr el bienestar tanto en ambientes domésticos, laborales como de ocio.In recent years, the implementation of air conditioning devices has become a necessity, essential to achieve well-being in both domestic, work and leisure environments.
El estado de Ia técnica ha evolucionado tanto que se ofertan en el mercado dispositivos climatizadores económicos, de gran rendimiento, de fácil instalación y muy silenciosos pero todos ellos carecen de sistemas óptimos para Ia eliminación de los líquidos condensados procedentes de los desagües de las distintas unidades que los componen.The state of the art has evolved so much that economic, high-performance, easy-to-install and very quiet climate control devices are offered on the market but all of them lack optimal systems for the elimination of condensed liquids from the drains of the different units that make them up.
DESCRIPCIÓN DE LA INVENCIÓN.DESCRIPTION OF THE INVENTION
EI invento consiste en Ia adaptación sobre Ia unidad condensadora exterior de forma que instalando, el dispositivo de recogida del agua condensada en el proceso de climatización, en el que se ubica una sencilla bomba eléctrica de condensados, un sensor de nivel de líquidos y un conjunto de pequeñas tuberías ascendentes a modo de canalizaciones con pulverizadores en sus extremos, se bombea el agua condensada sobre el condensador de Ia unidad exterior, y gracias a Ia elevada temperatura de éste y a Ia acción del ventilador del equipo junto con el intercambio de humedad, el líquido condensado se evapora en el ambiente exterior, eliminando Ia necesidad de realizar canalizaciones de desagüe y/o colocación de recipientes para recogida de líquidos dé

DESCRIPCIÓN DE LOS DIBUJOS.DESCRIPTION OF THE DRAWINGS.
Para comprender mejor el alcance de esta invención, vamos a describirla sobre los dibujos adjuntos en los que se ha materializado un diseño preferido de Ia misma dado a título de ejemplo y sin carácter limitativo.To better understand the scope of this invention, we will describe it on the accompanying drawings in which a preferred design of the same given by way of example and without limitation has materialized.
La figura 1 muestra una vista trasera de una unidad condensadora de exteriores con el invento instalado yFigure 1 shows a rear view of an outdoor condensing unit with the invention installed and
La figura 2 muestra una vista lateral del mismo.Figure 2 shows a side view of it.
Podemos comprobar que, en los dibujos, hemos representado por (1) a Ia unidad condensadora exterior de un equipo de aire acondicionado, (2) recipiente para líquidos condensados, (3) dispositivo sensor de nivel de líquido, (4) bomba de impulsión, (5) canalizaciones ascendentes, (6) aspersores y (7) .rejilla de ventilación.We can verify that, in the drawings, we have represented (1) the external condensing unit of an air conditioning unit, (2) container for condensed liquids, (3) liquid level sensor device, (4) drive pump , (5) ascending pipes, (6) sprinklers and (7). Ventilation grill.
REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
Como se puede observar en los dibujos, el invento está conformado sobre una unidad condensadora de un equipo de aire acondicionado (1) y está constituido por un sensor de nivel de líquidos (3) que detecta Ia presencia y nivel de líquido que se acumula en el recipiente (2) de recogida de líquidos condensados que activa, en caso de alcanzar un nivel adecuado de líquido en el recipiente, Ia bomba eléctrica de impulsión (4). Esta bomba impulsa el líquido condensado a
través de las canalizaciones verticales traseras (5), ancladas sobre Ia rejilla de ventilación del equipo condensador exterior y es emitido al exterior en forma de una fina lluvia gracias a los aspersores (6). El agua vertida por los aspersores (6) cae directamente sobre Ia rejilla de ventilación (7) trasera de Ia unidad condensadora (1) que, al entrar en contacto con ella se evapora rápidamente influyendo para ello tanto Ia temperatura del condensador como el efecto del ventilador interior del condensador, así como Ia humedad del ambiente exterior.As can be seen in the drawings, the invention is formed on a condensing unit of an air conditioning unit (1) and is constituted by a liquid level sensor (3) that detects the presence and level of liquid that accumulates in the container (2) for collecting condensed liquids that activates, in case of reaching an adequate level of liquid in the container, the electric discharge pump (4). This pump drives the condensed liquid to through the rear vertical pipes (5), anchored on the ventilation grid of the external condensing equipment and is emitted to the outside in the form of a fine rain thanks to the sprinklers (6). The water discharged by the sprinklers (6) falls directly on the rear ventilation grill (7) of the condensing unit (1) which, when in contact with it, evaporates rapidly, influencing both the temperature of the condenser and the effect of the internal condenser fan, as well as the humidity of the external environment.
Una vez que el nivel de líquido del recipiente de recogida de condensados (2) se reduce, el sensor Io detecta y detiene Ia acción de Ia bomba y, por tanto, de los aspersores.Once the liquid level of the condensate collection container (2) is reduced, the sensor detects and stops the action of the pump and, therefore, of the sprinklers.
Como se puede observar, el invento es tan efectivo como sencillo y original. Este conjunto de elementos como son el sensor, Ia bomba, tuberías de canalización y aspersores son sencillos de manipular e instalar y económicos.As can be seen, the invention is as effective as it is simple and original. This set of elements such as the sensor, the pump, pipes and sprinklers are simple to handle and install and economical.
Con el invento, incluso se reducen significativamente los costos de instalación, que como ya se ha comentado, hace innecesaria Ia instalación de canalizaciones de desagüe que, en muchas ocasiones, afean las fachadas de los edificios, así como los gastos en energía ya que el agua vertida por los aspersores sobre Ia rejilla facilita Ia eliminación del calor y mejora el rendimiento térmico de Ia instalación, tal y como se puede observar en los dibujos anexos.
Dentro de Ia esencialidad de Ia invención, caben las variantes de detalle, asimismo protegidas y así podrá variar el tipo sensor de nivel, bomba de impulsión, características y cantidad canalizaciones de impulsión y de los aspersores, así como las dimensiones de las distintas partes del sistema, y desde luego, el material empleado.
With the invention, installation costs are even significantly reduced, which, as already mentioned, makes it unnecessary to install drainage pipes that, in many cases, affect the facades of buildings, as well as energy costs since Water poured by the sprinklers on the grid facilitates the elimination of heat and improves the thermal efficiency of the installation, as can be seen in the attached drawings. Within the essentiality of the invention, the detail variants are also protected, so that the type of level sensor, discharge pump, characteristics and quantity of discharge and sprinkler pipes, as well as the dimensions of the different parts of the device can vary system, and of course, the material used.
