Model to determine the State of Charge of water as a phase change material integrated in a household refrigerator

Description: The purpose of this paper is to provide an alternative approximation for the methodology of the estimation of the State of Charge (SOC) of a Thermal Battery that uses latent heat energy storage (LHS). For that, a commercial household refrigerator with phase change materials (PCM) was used as the studied device. As the primary use of the LHS system is to use the PCM to charge-discharge energy during phase change, the refrigerator would achieve constant temperatures, which can be modelled as steady-state. The hypothesis is that heat transfer model could be simplified, and the assumption of the PCM as a black-box can be made. If possible, the SOC could be determined by the use of energy balances. And hence, most of the complex aspects of the system could be avoided. Experimental results proven that the model was able to estimate a very good approximation of the SOC of the thermal battery during complete and partial cycles using a non-intrusive and easy methodology.
