摘要：The article presents the results and analysis of comparative tests carried out on a thermal storage wall modified with phase change material (PCM) in a selected time interval. These tests were carried out in real climatic conditions in external research chambers. The same transitional period has been compared, two consecutive calendar years, 2017 and 2018. The months of March and April were used for the analysis, which are characterized by large fluctuations of temperatures between day and night. Based on meteorological data for the Rzeszów-Jasionka station, the months of March and April are characterized by a longer period of sunshine and significant temperature fluctuations, which qualifies these months in the transition period for moderate climate in Poland. Selected physical parameters characterizing the influence of phase change materials on the thermal efficiency of a modified barrier were analysed. Analysis of selected parameters confirmed the repeated, beneficial effect of PCM on the stabilization of temperature in the internal space in selected research periods.
