摘要: The present experimental investigation covers the construction of a LHTES (latent heat thermal energy storage system), which uses NaNO3 (sodium nitrate) as PCM (phase change material). unit is filled with 300 kg PCM. For transfer, vertically arranged bimetallic mono tube longitudinal fins used. increase flux into/from Thermal oil used transfer medium, it allows working temperature up to 400 °C. This able store 60 kWh and can be loaded power 200 kW. One part results presented in this paper was determination storable comparison data from literature calculations. Additionally, melting behavior measured sensors located at different positions over height unit. Finally, entrance medium changed top bottom could detected.
