Abstract

Método para la gestión de un calentador de agua de acumulación (1) en el que el agua se calienta mediante un elemento calefactor (3) dirigido por un regulador (4), comprendiendo dicho método, - una primera etapa, durante una secuencia de ciclos de extracción, - en la que se adquiere la información con respecto a un perfil de extracción de dicha secuencia de ciclos de extracción, realizándose dicha adquisición de la información durante el primero de dichos ciclos de extracción - una segunda etapa, - en la que se asigna a la temperatura del agua (Tm) el valor de la temperatura de extracción (Tset.k) suficiente para garantizar dicha extracción a la temperatura de uso (Tu), infiriéndose dicho valor de la temperatura de extracción (Tset.k) a partir de la información anterior adquirida y considerándose dicha temperatura del agua (Tm) representativa de la distribución de la temperatura dentro del depósito de almacenamiento (2) de dicho calentador de agua de acumulación (1) - en el que la temperatura del agua (T, T(tc)) se mide en una zona de dicho depósito de almacenamiento (2) que, en relación con otras zonas, puede verse más influida por las variaciones de temperatura debido a la entrada de agua fría caracterizada porque - dicho perfil de extracción se repite sustancialmente sin cambios en posteriores ciclos de extracción - dicha segunda etapa se realiza antes del tiempo (tik) de inicio de cada extracción (Pk) de todas las extracciones (n) comprendidas en cada ciclo de extracción - dicha temperatura del agua (Tm) se mantiene inferior o igual a la temperatura establecida máxima (Tset.max) inferior a valores peligrosos, y caracterizado por que - dicha adquisición de información en el perfil de extracción comprende calcular, para cada una de dichas extracciones (k), - el tiempo de inicio de la extracción (tik,) - y la disminución de temperatura correspondiente (ΔTk) - realizándose dicho cálculo únicamente procesando los datos obtenidos - a partir de la medición del tiempo transcurrido (t, tc), - a partir de dicha temperatura del agua (T, T(tc)) medida en una zona de dicho depósito de almacenamiento (2) que, en relación con otras zonas, puede verse más influida por las variaciones de temperatura debidas a la entrada de agua fría, - a partir de dicha temperatura del agua (Tm) en la que dicha temperatura del agua (Tm) es el valor resultante de la media de una o más temperaturas (T; T1, T2) medida a diferentes alturas (S, S1, S2) de dicho depósito de almacenamiento (2).Method for the management of an accumulation water heater (1) in which the water is heated by a heating element (3) directed by a regulator (4), said method comprising - a first stage, during a sequence of cycles of extraction, - in which the information is acquired with respect to an extraction profile of said sequence of extraction cycles, said acquisition of the information being carried out during the first of said extraction cycles - a second stage, - in which assigns to the water temperature (Tm) the value of the extraction temperature (Tset.k) sufficient to guarantee said extraction to the use temperature (Tu), said value of the extraction temperature (Tset.k) being inferred from of the previous information acquired and considering said water temperature (Tm) representative of the temperature distribution within the storage tank (2) of said accumulation water heater (1 ) - in which the water temperature (T, T (tc)) is measured in an area of said storage tank (2) which, in relation to other areas, may be more influenced by temperature variations due to the cold water inlet characterized in that - said extraction profile is repeated substantially without changes in subsequent extraction cycles - said second stage is carried out before the time (tik) of beginning of each extraction (Pk) of all the extractions (n) included in each extraction cycle - said water temperature (Tm) remains lower or equal to the maximum set temperature (Tset.max) lower than dangerous values, and characterized in that - said acquisition of information in the extraction profile comprises calculating, for each of said extractions (k), - the start time of the extraction (tik,) - and the corresponding temperature decrease (ΔTk) - said calculation being performed only by processing the data obtained - from the measurement of elapsed time (t, tc), - from said water temperature (T, T (tc)) measured in an area of said storage tank (2) which, in relation to other areas , can be more influenced by temperature variations due to cold water inlet, - from said water temperature (Tm) at which said water temperature (Tm) is the resulting value of the average of one or more temperatures (T; T1, T2) measured at different heights (S, S1, S2) of said storage tank (2).
