Abstract (en)

[origin: GB2455748A] A latent heat storage device has an elastomeric container 1 to contain a phase change material (PCM) 2 containing nano-particle conductive powder, which may be carbon or aluminium, arranged in a containment vessel 3. The elastomeric container 1 may have walls arranged to be as thin as possible, maximising heat transfer, whilst being strong enough to retain the PCM, may be formed into square or circular chambers or may be a continuous tube sealed at both ends, folded, and inserted into the containment vessel 3. Heat exchange fluid 6 may flow through the vessel in a closed circuit, passing through gaps between adjacent tubes or folds of the elastomeric container 1, these gaps being restricted by thermal expansion of the PCM thus avoiding overheating. The containment vessel may provide the structural integrity for the device when the PCM has melted, have a sealed lid, insulated panels or walls and a plurality of compartments and different PCMs, the heat exchange fluid 6 being directed to different compartments in turn or selectively. The device may have several vessels 3, which may have different atmospheres, e.g. reduced oxygen.
