Description

SISTEMA INTELIGENTE CON COMUNICACIÓN INALAMBRICA PARA RECIRCULACIÓN DE AGUA, REGULACIÓN DE TEMPERATURA Y AHORRO DE ENERGÍA PARA USO EN INMUEBLES SMART SYSTEM WITH WIRELESS COMMUNICATION FOR WATER RECIRCULATION, TEMPERATURE REGULATION AND ENERGY SAVING FOR USE IN REAL ESTATE
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En lo referente al uso de agua caliente en el ámbito doméstico, industrial o comercial, se ha detectado a través del tiempo, un constante malgasto del fluido que se genera durante su proceso de precalentamiento, cuando se requiere alcanzar una mayor temperatura a la del ambiente para algún proceso. Regarding the use of hot water in the domestic, industrial or commercial environment, a constant waste of the fluid generated during its preheating process has been detected over time, when it is required to reach a higher temperature than the environment For some process.
El referido periodo necesario para aumentar la temperatura del agua conlleva un desperdicio considerable de la misma, la cual en la mayoría de los casos no se recupera ni utiliza. The aforementioned period necessary to increase the temperature of the water entails a considerable waste of it, which in most cases is not recovered or used.
El sistema que propone la presente invención ha sido diseñado para eliminar la problemática antes referida, para lo cual hace uso de tecnología moderna, así como de dispositivos especializados para dicha tarea como son las válvulas electrónicas o solenoides, entre otros componentes. DESCRIPCIÓN DE LA INVENCIÓN The system proposed by the present invention has been designed to eliminate the aforementioned problem, for which it makes use of modern technology, as well as specialized devices for said task such as electronic valves or solenoids, among other components. DESCRIPTION OF THE INVENTION
Este sistema de ahorro de agua y energía tiene como propósito el recircular el agua que sale del dispositivo de calentamiento del inmueble (caldera, boiler, calentador estacionario, calentador de paso, etc.), mientras regula la temperatura del agua a la especificada en el módulo de control, evitando con ello, el desperdicio de agua y energía durante el proceso de precalentamiento.  The purpose of this water and energy saving system is to recirculate the water that comes out of the building's heating device (boiler, boiler, stationary heater, step heater, etc.), while regulating the water temperature to the one specified in the control module, thereby avoiding wastage of water and energy during the preheating process.
Mediante una electroválvula de tres vías y dos posiciones se dirige el paso de agua hacia el inmueble o al recipiente de recirculación, dependiendo de la temperatura que tenga el fluido; una electroválvula de dos estados restringe o permite el acceso de agua caliente que sale del dispositivo de calentamiento hacia el elemento mezclador el cual cuenta con un sensor de temperatura, éste envía la señal de la medición al módulo de control del sistema que procesa la información por medio de microcontroladores, y en función a esto, el sistema regula la cantidad de agua fría necesaria para ajustar la temperatura del agua a la especificada por el usuario. Through a three-way, two-way solenoid valve, the water passage is directed to the building or to the recirculation vessel, depending on the temperature of the fluid; a two-state solenoid valve restricts or allows access of hot water leaving the heating device to the mixing element which has a temperature sensor, which sends the measurement signal to the system control module that processes the information by microcontroller medium, and according to this, the system regulates the amount of cold water necessary to adjust the water temperature to that specified by the user.
Mientras el agua no ha alcanzado la temperatura adecuada, el sistema la recircula hacia un recipiente por medio de una bomba que envía el agua de vuelta al dispositivo de calentamiento, evitando así el desperdicio de agua y energía. Cuando el sistema ha controlado y regulado la temperatura del agua a la temperatura requerida, permite el paso de la misma por el sistema hacia el inmueble. While the water has not reached the proper temperature, the system recirculates it to a container by means of a pump that sends the water back to the heating device, thus avoiding waste of water and energy. When the system has controlled and regulated the temperature of the water at the required temperature, it allows it to pass through the system to the property.
Durante el periodo de uso de agua en el inmueble, el sistema regula en tiempo real la alimentación y temperatura del fluido, haciendo el uso de la energía lo más eficientemente posible y evitar así el desperdicio de agua que no esté a la temperatura deseada. During the period of use of water in the building, the system regulates in real time the feeding and temperature of the fluid, making the use of energy as efficiently as possible and thus avoiding wasting water that is not at the desired temperature.
De la misma manera, en virtud de que el usuario contará con la capacidad de fijar la temperatura de salida del sistema, ya sea mediante el uso de controles electrónicos o sistemas de comunicación inalámbrica, ya no será necesario el empleo de agua fría adicional para templar el agua al momento de utilizarla, como frecuentemente es regulada la temperatura del agua al día de hoy en regaderas y fregaderos. In the same way, because the user will have the ability to set the system's output temperature, either through the use of electronic controls or wireless communication systems, it will no longer be necessary to use additional cold water to tune the water at the time of use, as the temperature of the water is frequently regulated today in showers and sinks.
Para complementar la descripción y con objeto de asistir a una mejor comprensión de las características del invento, se acompaña a la presente descripción, como parte integrante de la misma, un diagrama, en el cual con carácter ilustrativo y no limitativo, se presenta lo siguiente: Figura 1: To complement the description and in order to assist in a better understanding of the characteristics of the invention, a diagram is attached to the present description, as an integral part thereof, in which, for illustrative and non-limiting purposes, the following is presented : Figure 1:
Muestra un diagrama del sistema y sus componentes en estado de reposo, en la que las dos válvulas principales para el funcionamiento y circulación del agua, tanto fría como caliente, se encuentran en estado cerrado. Este diagrama ilustra los componentes del sistema, entre los que figuran: Módulo de control (1), que mediante el uso de microcontroladores se encargará de procesar la información así como de realizar las operaciones necesarias en el sistema, de igual forma se intercomunicará con un sensor de temperatura (8) que le proveerá de la información del estado térmico del agua para la operación así como también con un módulo inalámbrico para la comunicación con otros sistemas. It shows a diagram of the system and its components in the state of rest, in which the two main valves for the operation and circulation of water, both cold and hot, are in the closed state. This diagram illustrates the components of the system, including: Control module (1), which through the use of microcontrollers will be responsible for processing the information as well as performing the necessary operations in the system, in the same way it will intercommunicate with a Temperature sensor (8) that will provide you with the information of the thermal state of the water for the operation as well as with a wireless module for communication with other systems.
También se muestran una electroválvula de cuatro vías-dos posiciones (2) que es la válvula que se encargará de recircular el agua o permitir el acceso al inmueble cuando las condiciones se hayan cumplido, es decir la temperatura sea la adecuada. Also shown are a four-way solenoid valve - two positions (2) which is the valve that will be in charge of recirculating the water or allowing access to the property when the conditions have been met, that is, the temperature is adequate.
La válvula dos vías-dos posiciones (3) permitirá el paso de agua caliente cuando sea solicitada por el usuario, para ser mezclada con el agua fría, cuyo suministro será regulado por una electroválvula reguladora de caudal (4) con el objetivo de establecer la proporción de agua fría con respecto a la caliente para alcanzar la temperatura requerida. The two way valve - two positions (3) will allow the passage of hot water when requested by the user, to be mixed with the cold water, whose supply will be regulated by a flow regulating solenoid valve (4) in order to establish the proportion of cold water with respect to the hot to reach the required temperature.
De igual forma, se muestra el recipiente plástico (5) en el cual se almacenará agua que se recircula en el sistema para posteriormente, mediante una bomba hidráulica (6), se regresa al dispositivo de calentamiento. Likewise, the plastic container (5) in which water that is recirculated in the system will be stored for later, by means of a hydraulic pump (6), is returned to the heating device.
Por último, el sistema contará con una electroválvula anti-retorno (7) que aislará la alimentación de agua al dispositivo de calentamiento mientras el sistema opera, mejorando de esta forma su eficiencia en la recirculación y ahorrando así agua y energía. Finally, the system will have a non-return solenoid valve (7) that will isolate the water supply to the heating device while the system operates, thereby improving its recirculation efficiency and thus saving water and energy.
En la figura también se presentan las siguientes referencias para diferencias las etapas térmicas del agua: agua fría (AF), agua caliente (AC), agua recirculada (AR), drene de agua de tuberías (DAT), agua mezclada (AM), agua a temperatura fuera de parámetro (ATFP), agua a temperatura deseada (ATD). The figure also shows the following references for differences in the thermal stages of water: cold water (AF), hot water (AC), recirculated water (AR), drain of water from pipes (DAT), mixed water (AM), water at out of parameter temperature (ATFP), water at desired temperature (ATD).
