A mathematical model for a rock-bed energy storage system has been developed for a solar-dehumid-ification lumber dryer and shown to give good correlation with experimental data. The drying rate of yellow poplar lumber was mathematically related to the collector area and storage size. A simple economic model was used to compare solar, solar-dehumidification, dehumidification, and wood-fired boiler drying systems.
