Resumen

CATHERINE, Quinton; WHEELER, Jacques; WILKINSON, Richardt  y  DE JAGER, Gerhard. Hot water usage profiling to improve geyser efficiency. J. energy South. Afr. [online]. 2012, vol.23, n.1, pp.39-45. ISSN 2413-3051.

This paper presents an intelligent hot water cylinder (HWC) (referred to as geyser) usage profiling system to provide peak demand side management and improve HWC efficiency in a typical household. The study highlights current control topologies used to improve geyser efficiency, as well as the design of the final geyser controller. The system consists of a PIC microcontroller used to determine individually based hot water usage profiles of the user. The controller then regulates the temperature of the geyser according to the demand profile developed. From the results it is apparent that by controlling the geyser temperature and thereby heat loss, savings can be made.

Palabras clave : hot water profiling; microcontroller; geyser temperature control.
