Abstract
A device to store energy includes a phase change material (PCM), with a phase change temperature Tc, contained in a sealed container and constituting a storage core. A source to exchange heat with the PCM, at a temperature TA, to cause a phase change of the PCM. A recuperator to exchange heat with the PCM, at a temperature TB, to cause a phase change of the PCM in the opposite direction to the phase change produced by the source. A controller to control the heat flows between the PCM, the source and the recuperator. An apertured support in contact with the PCM in the sealed container and in thermal contact with the source and the recuperator.
Claims30
An energy storage device comprising:
- a load of a phase change material (PCM), with a phase change temperature Tc, contained in a leaktight container and constituting an energy storage core;
- a source to exchange heat with the PCM, at a temperature TA, to cause a phase change of the PCM;
- a recuperator to exchange heat with the PCM, at a temperature TB, to cause a phase change of the PCM in an opposite direction to the phase change produced by the source;
- a controller to control heat flows between the PCM, the source and the recuperator;
- and
- a perforated support, in contact with the PCM in the leaktight container and in a thermal contact with the source and the recuperator.
