De esta manera se puede conseguir un ahorro adicional en cuanto a los costes de inversión de la instalación.This way you can achieve savings additional in terms of the investment costs of the installation.

Para su mejor compresión, se adjunta a título de ejemplo explicativo pero no limitativo unos dibujos de una realización preferente de la presente invención.For better compression, it is attached as explanatory but not limiting example some drawings of a preferred embodiment of the present invention.

La figura 1 muestra un esquema de una instalación de agua corriente de acuerdo a las presentes mejoras;Figure 1 shows a diagram of an installation of running water according to the present improvements;

La instalación mejorada del ejemplo de la figura 1 es una instalación de agua corriente, del tipo de las existentes en las viviendas. La instalación está compuesta, al igual que el ejemplo mostrado en la figura 1 de la Patente original, por un primer tramo común (1) que presenta una llave de corte (19) y un regulador de la presión de la instalación (20), un circuito de agua caliente (2) con sistema de caldera (22), un circuito de agua fría (3) y, al menos, un punto de consumo (4) en este caso un grifo para agua fría y caliente. El grifo (4) dispone de un dispositivo (5) accionable por el usuario y que pone en comunicación los circuitos de agua caliente (2) y agua fría (3), como ya se explicó en la descripción de la Patente original. El circuito de agua caliente (2) opera a mayor presión que el circuito de agua fría (3). Esto se consigue en el ejemplo mediante el regulador de presión (7) situado al inicio del circuito de agua fría (3).The improved installation of the example in the figure 1 is a running water installation, of the existing type In the houses. The installation is composed, as is the example shown in figure 1 of the original Patent, by a first common section (1) presenting a cutting key (19) and a installation pressure regulator (20), a water circuit hot (2) with boiler system (22), a cold water circuit (3) and at least one consumption point (4) in this case a tap for hot and cold water The tap (4) has a device (5) user-operated and communicates circuits of hot water (2) and cold water (3), as explained in the Description of the original patent. The hot water circuit (2) operates at a higher pressure than the cold water circuit (3). This is achieved in the example by means of the pressure regulator (7) located at the beginning of the cold water circuit (3).

El ejemplo mostrado también comparte con el mostrado en la Patente original la válvula (9'), y el presostato (10) situados en el circuito de agua fría.The example shown also shares with the shown in the original Patent the valve (9 '), and the pressure switch (10) located in the cold water circuit.

De forma característica para las presentes mejoras, los medios de evacuación (8) conectan el circuito de agua fría (3) con un punto de la instalación situado aguas arriba del generador de agua caliente o caldera (22), lo que en el ejemplo se realiza a través de una bomba (13), que podrá ser de similares características a la bomba utilizada en el ejemplo de la Patente original para sacar agua del depósito intermedio, y de una válvula antirretorno (23).Characteristically for those present improvements, the evacuation means (8) connect the water circuit cold (3) with a point of the installation located upstream of the hot water generator or boiler (22), which in the example is performed through a pump (13), which may be similar characteristics to the pump used in the example of the Patent original to draw water from the intermediate tank, and from a valve non-return (23).

El presostato (10) gobierna el funcionamiento de la válvula (9) y de la bomba (13) a través del relé (24).The pressure switch (10) governs the operation of the valve (9) and the pump (13) through the relay (24).

Cuando se acciona el dispositivo (5) a través del mando (6), quedan conectados los circuitos de agua caliente (2) y de agua fría (3), lo que provoca un aumento de la presión del circuito de agua fría (3). Al aumentar la presión, el presostato (10) conecta el relé (24), el cual cierra la válvula (9') y pone en funcionamiento la bomba (13). Cuando la temperatura del agua en el punto de consumo (4) es la requerida, los circuitos de agua fría y caliente dejan de estar conectados. El funcionamiento de la bomba (13) hace que disminuya la presión por debajo del nivel de alarma del presostato (10), el cual detiene la bomba (13) y abre la válvula (9').When the device (5) is operated through the control (6), the hot water circuits (2) and cold water (3), which causes an increase in circuit pressure of cold water (3). When the pressure increases, the pressure switch (10) connects the relay (24), which closes the valve (9 ') and puts pump operation (13). When the water temperature in the consumption point (4) is the one required, the cold water circuits and Hot stop being connected. Pump operation (13) causes the pressure to fall below the alarm level of the pressure switch (10), which stops the pump (13) and opens the valve (9 ').

Gracias a esta conexión de los medios de evacuación (8) a un punto situado aguas arriba de la caldera (22), es posible prescindir del depósito de almacenamiento intermedio mostrado en la figura 1 de la Patente original. De esta manera se simplifica la instalación, disminuyendo sus costes y ahorrando espacio.Thanks to this media connection of evacuation (8) to a point located upstream of the boiler (22), it is possible to dispense with the intermediate storage tank shown in figure 1 of the original patent. This way it simplifies installation, reducing costs and saving space.

Otra mejora prevista, no mostrada en la figura, consiste en sustituir el dispositivo (5) por una válvula de accionamiento manual, de tipo conocido, que conecte los circuitos de agua caliente (2) y de agua fría (3), careciendo de medios sensibles a la temperatura, siendo el usuario quien deba comprobar cuándo la temperatura de la instalación ha alcanzado la temperatura requerida.Another expected improvement, not shown in the figure, consists in replacing the device (5) with a valve manual drive, of known type, that connects the circuits of hot water (2) and cold water (3), lacking sensitive means at the temperature, the user being the one who should check when the installation temperature has reached the temperature required

De esta manera, también se disminuyen los costes de inversión de la inversión. Si bien esta mejora conlleva una cierta reducción de la comodidad para el usuario, esto puede no ser un inconveniente en cierto tipo de instalaciones, como por ejemplo instalaciones con bajo índice de consumo, tales como segundas residencias.In this way, costs are also reduced Investment investment. While this improvement involves a some reduction of user comfort, this may not be an inconvenience in certain types of facilities, such as facilities with low consumption rate, such as second residences

Como ya se indicó en la Patente original, existen numerosas variantes que quedan dentro del alcance de la presente invención y las mejoras aquí expuestas. Por ejemplo, en una realización alternativa, será posible prescindir de la válvula (9'), sustituyéndola por una válvula antirretorno, si esta función no pudiese realizarse mediante el regulador (7). De esta manera se podrá conectar directamente la señal del presostato (10) a la bomba (13). También resultarán evidentes para un experto en la materia múltiples combinaciones entre las mejoras aquí expuestas y las diferentes realizaciones descritas en la Patente Original.As already indicated in the original Patent, there are numerous variants that remain within the scope of this invention and the improvements set forth herein. For example, in a alternative embodiment, it will be possible to dispense with the valve (9 '), replacing it with a non-return valve, if this function does not could be done by the regulator (7). This way it You can directly connect the pressure switch signal (10) to the pump (13). They will also be evident to an expert in the field multiple combinations between the improvements presented here and the different embodiments described in the Original Patent.

En general, todo lo no que afecte, altere, cambie o modifique la esencia de las mejoras descritas, será variable a los efectos de la presente invención.In general, everything that does not affect, alter, change or modify the essence of the described improvements, it will be variable to Effects of the present invention.
