Although water is a cheap and effective medium for thermal energy storage, other options are currently being studied,
to increase the storage density or to reduce the cost of the storage. The authors have been developing a system which
combines the advantages of stratified sensible heat storage and latent, phase change heat storage; i.e. a hot water
storage tank with stratification where a phase change material (PCM) is included into a spiral tube installed in the top
of the tank. The PCM used was a granular PCM–graphite compound of about 90 vol:% of sodium acetate trihydrate
and 10 vol:% graphite. This paper presents the results of an experimental investigation of the performance of the new
storage concept, and of a conventional hot water storage tank for comparison. The data are further analysed with
respect to the energetic and exergetic performance of the two systems.
The authors would like to acknowledge the companies
Lapesa S.A. and SGL Technologies for their collabora-
tion in this research. The work was partially funded with
the project ENE2005-08256-C02-01/ALT. Dr Marc
Medrano would like to thank the Spanish Ministry of Education and Science for his Ramon y Cajal research
appointment. |
