Abstract

Se proporciona un calentador de agua de tipo de almacenamiento, que puede tener ya sea un aparato de calentamiento basado en combustible o eléctrico, con un sistema de control que incorpora un algoritmo de control que verifica el tiempo entre las demandas de calor y luego ajusta la temperatura de punto de ajuste del agua del tanque por consiguiente para disminuir los efectos de estratificación del agua debido a las demandas de calor periódicas, y también ahorra energía. Cuando el tiempo entre las demandas de calor consecutivas es menor que un tiempo de retroceso predeterminado, para un número de demandas de calor igual a un límite de retroceso predeterminado, un modo de retroceso se activa y responsivamente opera para reducir la temperatura de punto de ajuste por una desviación de retroceso predeterminada en el siguiente ciclo. La temperatura de punto de ajuste de control original se restaura una vez que el tiempo entre dos demandas de calor sucesivas es mayor que el tiempo de retroceso.
