THERMAL STORAGE SYSTEMS (TSS) BY PHASE CHANGE MATERIALS (PCM) COMPRISING A DEVICE FOR EVALUATING THE TSS LOAD

摘要

"Thermal Storage Systems (SST) by Phase Change Materials (MCP), comprising a device for evaluating the load of the SST." CEA The invention relates to a Thermal Storage System (SST) by Phase Change Material comprising a tank (1) intended to receive an MCP (2), and a device for evaluating the level of charge of the SST, characterized in that the device for evaluating the level of charge of the SST comprises- a circulation system of a gas through the MCP (2) comprising: ∘ a device for injecting the gas (6) into the tank (1) in contact with the MCP (2) at a lower terminal (21), ∘ an outlet device gas (7) out of the tank (1) at an upper terminal (20), and a sensor (9) configured to deliver a measurement representative of the evolution of the pressure drop of the gas injected passing through the MCP (2) between the lower bound (21) and the upper bound (20) and depending on the crystallization state of the MCP (2) .The present invention will find its application in heat and / or cold networks, urban, rural or industrial as well as in the storage of solar energy. The invention may also find applications in housing, thermal transport outside networks (trucks, boats ...) and thermal management of on-board systems.
