20150188388 | FACILITY FOR TRANSFORMING HEAT ENERGY - The facility for transforming heat energy includes an energy-storage device including an HT vat containing a heat-transfer fluid HT in pressurized gaseous phase, a PCM vat containing a phase-change material, as PCM material, the PCM vat and the HT vat being positioned relative to one another such as to enable a transfer of heat energy between the PCM material and the HT fluid, a first electric generator connected to the HT vat by a fluid forward channel and a fluid backward channel, the generator generating power from a kinetic energy of the pressurized gaseous fluid, and a heat pump, transferring heat energy from a cold source to the energy-storage device in order to heat the HT fluid contained in the HT vat and/or to provide energy to the PCM material. The invention can be used for the general supply of energy, heat, domestic hot water or electricity of a building. | 07-02-2015 |
