Experimental evaluation at pilot plant scale of multiple PCMs (cascaded) vs. single PCM configuration for thermal energy storage

The present paper provides on one hand, a literature review of the different studies available in the scientific literature where the concept of multiple phase change materials (PCM) configuration, also named cascaded or multi-stage, has been presented and on the other hand, an experimental evaluati...

Two PCM with melting temperatures in a temperature range of 150 e200 C were selected due to their high value of heat of fusion and compared: d-mannitol and hydroquinone.

Results showed that the multiple PCMs configuration introduced an effectiveness enhancement of 19.36% if compared with single PCM configuration as well as a higher uniformity on the HTF temperature difference between the inlet and outlet.The work is partially funded by the Spanish Government (ENE2011-22722 and ULLE10-4E-1305).
