Abstract
The temperature-history method, proposed by Yinping et al, is a simple andeconomic way to determine the main thermophysical properties of materialsused in thermal energy storage based on solid–liquid phase change. It isbased on comparing the temperature history of a phase-change materialsample and a sample of a well known material upon cooling down. In thispaper we describe a further developed evaluation procedure to determinecpand has temperature dependent values which was not the case in Yinping’s method,based on the same experimental procedure. Given the suitability of theseproperties to calculate thermal energy storage using these materials, the methodis proposed to present the results obtained in the form of enthalpy–temperaturecurves. A discussion about the errors produced by this method and anexperimental improvement are proposed too.
