Abstract
This study shows results of the experimental investigation of regularly structured Composite Latent Heat Storages. Common solid-liquid Phase Change Materials used as latent heat storages have a low thermal conductivity, which leads to high temperature differences inside large PCM volumes. This drawback is compensated by the combination with specially designed frame-structures made of aluminum to enhance the transport of thermal energy inside the regularly structured Composite Latent Heat Storage. A prototype is investigated experimentally on a test rig, where the heat load and temperatures are measured while the phase change process is observed optically. The results are compared to a solid block PCM heat storage.
