Abstract

Device for reducing energy consumption of hot water, consisting of a heat exchanger located in a drain through which discharged or drained water flows on one side and cold water from the distribution network on the other side, producing an exchange of heat between both waters, without mixing, so that once the cold water from the outside is passed through the exchanger, it is directed to a valve or mixer tap where it is mixed with hot water. Having raised the temperature of the cold water the amount of hot water is reduced and therefore also saves the energy needed to heat the hot water saved.

Es objeto de la presente invención un dispositivo de ahorro de energía reductor del consumo de agua caliente, que como el propio título de la invención enuncia, permite reducir el consumo de agua caliente y por lo tanto reducir la energía directamente asociada a la cantidad de consumo de agua caliente ahorrado.The object of the present invention is a energy saving device reducing water consumption hot, which as the title of the invention itself states, allows to reduce the consumption of hot water and therefore reduce the energy directly associated with the amount of water consumption Hot saved.

Caracteriza a la presente invención la especial configuración, diseño y ubicación de los medios empleados para lograr el fin propuesto de reducción de consumo de agua caliente.Characterizes the present invention the special configuration, design and location of the media used to achieve the proposed end of water consumption reduction hot.

El objetivo de la presente invención se logra mediante el aprovechamiento de la energía contenida en el agua desaguada. Para ello se hace pasar al agua desaguada por un intercambiador de calor donde el calor contenido en dicha agua se transfiere al agua fría de entrada, previamente a ser mezclada con el agua caliente, resultando como consecuencia un menor consumo de agua caliente.The objective of the present invention is achieved. by harnessing the energy contained in the water drained For this, the drained water is passed through a heat exchanger where the heat contained in said water is transfers to the cold inlet water, before being mixed with hot water, resulting in lower consumption of Hot water.

Por lo tanto, la presente invención se circunscribe dentro del ámbito de los medios economizadores de energía y de modo particular de entre aquellos basados en el aprovechamiento de la energía contenida en un fluido a

Antecedentes de la invenciónBackground of the invention

En el ámbito doméstico hasta el momento se da la circunstancia de que el agua desaguada, en duchas y similares, no se aprovecha el potencial energético contenido en dicha agua desaguada ya que está siendo tirada al desagüe a una relativa alta temperatura, siendo susceptible de ser aprovechada la energía contenida en dicha agua.In the domestic sphere so far there is the  circumstance that the drained water, in showers and the like, does not the energy potential contained in said water is used drained since it is being thrown into the drain at a relatively high temperature, being able to be harnessed energy contained in said water.

La energía utilizada para calentar el agua se invierte en calentar el medio (aire, cuerpo y ducha) y el resto se vierte por el desagüe sin poder ser aprovechada. Por otro lado, en los grifos mezcladores de duchas y similares, lo que se produce es un proceso de mezcla entre volúmenes de agua caliente y de agua fría hasta alcanzar la temperatura del agua de salida conveniente al usuario.The energy used to heat the water is invests in heating the medium (air, body and shower) and the rest is poured down the drain without being able to be used. On the other hand, in shower mixer taps and the like, what is produced is a process of mixing between volumes of hot water and water cold until the temperature of the outlet water is reached to user.

Por lo tanto, el objetivo de la presente invención es el de reducir el consumo de agua caliente, y por ende, el de la energía necesaria para calentar el volumen de agua ahorrado, buscando la manera o el modo de aprovechar el potencial energético contenido en el agua desaguada.Therefore, the objective of the present invention is to reduce the consumption of hot water, and therefore , the energy needed to heat the volume of water saved, looking for the way or way to take advantage of the energy potential contained in the drained water.

Descripción de la invenciónDescription of the invention

La presente invención de dispositivo de ahorro de energía reductor del consumo de agua caliente consiste básicamente en la disposición de un intercambiador de calor situado en el desagüe.The present invention of saving device Energy reducing hot water consumption consists basically in the arrangement of a heat exchanger located in the drain.

En dicho intercambiador, por un lado, discurre o circula por un lado el agua desechada o desaguada mientras que por otro el agua fría proveniente de la red antes de pasar al mezclador. Resulta importante reseñar que el intercambio es únicamente de calor, sin que en ningún momento entren en contacto las aguas del desagüe con el agua de
ducha.In said exchanger, on the one hand, the discarded or drained water flows or circulates on the one hand while on the other the cold water coming from the network before passing to the mixer. It is important to note that the exchange is only of heat, without at any time the waters of the drain coming into contact with the water of
shower.

El agua fría tras su paso por el intercambiador de calor eleva su temperatura, por lo que la cantidad o flujo de agua caliente en la válvula mezcladora o grifo es claramente inferior a la cantidad necesaria de agua caliente que si el agua fría proviniese directamente de la red de suministro.Cold water after passing through the exchanger of heat raises its temperature, so the amount or flow of hot water in the mixing valve or tap is clearly less than the necessary amount of hot water than if the water cold came directly from the supply network.

Ahora bien, con el objetivo de lograr un mejor aprovechamiento en el proceso de intercambio de calor entre fluidos, el intercambiador puede contar con un elemento activo que aprovecha parte de la presión de la red para crear una convención forzada de modo que se favorece el intercambio de calor. Esta solución es muy indicada cuando no existe espacio físico para la instalación de un intercambiador pasivo que es mas grande.Now, in order to achieve a better use in the heat exchange process between fluids, the exchanger can have an active element that take advantage of part of the network pressure to create a convention forced so that heat exchange is favored. This solution is very indicated when there is no physical space for installation of a passive exchanger that is larger.

Si por ejemplo consideramos que la temperatura de entrada del agua fría es 12ºC y la del agua caliente es de 60ºC, suponiendo que la temperatura de salida del mezclador es de 38ºC y que la temperatura del agua de desagüe es de 30ºC, un intercambiador que elevara la temperatura del agua fría de 12ºC a 22ºC produciría un ahorro del consumo de agua caliente de un 38%.If for example we consider that the temperature cold water inlet is 12 ° C and hot water is 60 ° C, assuming that the outlet temperature of the mixer is 38 ° C and that the temperature of the drain water is 30 ° C, a exchanger that will raise the cold water temperature from 12ºC to 22ºC would produce a saving of hot water consumption of a 38%

Para ilustrar esto comparamos la ducha sin el intercambiador y con el intercambiador.To illustrate this we compare the shower without the exchanger and with the exchanger.

Realización preferente de la invenciónPreferred Embodiment of the Invention

A la vista de las figuras se describe seguidamente un modo de realización preferente de la invención propuesta.In view of the figures described then a preferred embodiment of the invention proposal.

En la figura 1, podemos observar que el dispositivo de ahorro de energía consiste en un intercambiador situado debajo del desagüe (1) por el que discurre el agua desaguada o desechada por un lado, mientras que por otro lado en un serpentín interior (2) se hace discurrir el agua fría (3) proveniente de la red de suministro, sin mezclarse ambas aguas en ningún momento, y con el objetivo de elevar la temperatura de dicha agua fría.In figure 1, we can see that the energy saving device consists of an exchanger located under the drain (1) through which the water flows drained or discarded on the one hand, while on the other hand in a Inner coil (2) cold water runs (3) from the supply network, without mixing both waters in no time, and with the aim of raising the temperature of said cold water.

El agua fría (3) una vez que ha pasado a través del intercambiador, que en la figura representada es un serpentín (2) discurre hasta la válvula o grifo mezclador (5), donde lógicamente, al haberse elevado la temperatura del agua proveniente de la red exterior, produce como consecuencia una reducción en el consumo de agua caliente (4).Cold water (3) once it has passed through of the exchanger, which in the represented figure is a coil (2) runs to the valve or mixer tap (5), where logically, having raised the temperature of the water coming of the external network, results in a reduction in the hot water consumption (4).

El intercambiador puede disponer de un elemento activo (no representado) que aprovecha la presión de la red para crear una convección forzada y favorecer el intercambio de calor.The exchanger can have an element active (not shown) that takes advantage of network pressure to create forced convection and favor the exchange of hot.

El dispositivo representado en la figura 1 muestra la realización que tendría lugar en una obra nueva, donde el intercambiador se integraría en la propia bañera o recipiente de desagüe.The device represented in figure 1 shows the realization that would take place in a new work, where the exchanger would be integrated in the bathtub or container itself Drain

Ahora bien, en todas aquellas instalaciones ya realizadas, con el objetivo de lograr los fines propuestos, el intercambiador sería un intercambiador desmontable (6), tal y como se muestra en la figura 2, y constructivamente hablando estaría conformado por una base o soporte (7), sobre el que se dispone un serpentín de intercambio (8) por el que discurre el agua fría, contando además con una tapa o cierre superior (9) que cuenta con dos conexiones; una para la entrada de agua fría proveniente de la red de distribución exterior, y otra para la conexión hacia la válvula o grifo mezclador.Now, in all those facilities already carried out, with the aim of achieving the proposed purposes, the exchanger would be a removable exchanger (6), just as it is shown in figure 2, and constructively speaking it would be formed by a base or support (7), on which a exchange coil (8) through which cold water runs, also having a top cover or closure (9) that has two connections; one for the cold water inlet coming from the external distribution network, and another for connection to the mixer valve or tap.
