| 摘要 |
The invention concerns a system for determining the charge level of a means for storing latent heat energy, said storage means comprising a reservoir partially filled with a phase change material of which the phase change is accompanied by a volume variation with a heat exchanger embedded in said material, said storage means being in a completely discharged state when the phase change material is substantially totally in a first state and in a completely charged state when the phase change material is substantially totally in a second state, characterised in that the system comprises: - a measurement fluid (4) intended to be poured into the reservoir (1) of the storage means, - means (5) for measuring the height of the measurement fluid in the reservoir, and - means for calculating the charge level of the storage means at a determined time in the operation of same, depending on the difference between the height of the fluid present in the reservoir when the storage means is completely discharged and the height of the liquid at said determined time. |
