Compatibility and durability of phase change materials (PCM) and packaging laminate films were tested in this study. The objective was to identify viable component materials for heat storage tube-sheets. The tube-sheets are the essential part of a patented latent heat storage device. The unique feature of the device is its offset arrangement of mass-producible units. The results of cycling tests on two PCMs and one laminate are presented in this paper. After more than 1000 accelerated cycles of charging and discharging tests, the tubes maintained operable stability and showed no sign of deterioration. The PCMs displayed the same temperature-time pattern during the entire cycling test. The packaging laminate was compatible with the PCM's and capable of maintaining satisfactory strength.
