The concept of octadecane wax impregnated wallboard for the passive solar application is a major thrust of the Oak Ridge National Laboratory (ORNL) Thermal Energy Storage (TES) program. Thus, ORNL has initiated a number of internal efforts in support of this concept. The results of these efforts are: The immersion process for filling wallboard with wax has been successfully sealed up from small samples to full-size sheets; analysis shows that the immersion process has the potential for achieving higher storage capacity than adding wax filled pellets to wallboard during its manufacture; analysis indicates that 75/degree/F is close to an optimum phase change temperature for the non-passive solar application; and the thermal conductivity of wallboard without wax has been measured and will be measured for wax impregnated wallboard. In addition, efforts are underway to confirm an analytical model that handles phase change wallboard for the passive solar application. 4 refs., 10 figs.
