Device for measuring the loading of a latent heat energy store using a copolymer mixed in with the latent heat store so that the transparency changes in a measurable fashion as latent heat is added or removed

摘要

Device (2) for measuring the loading of a latent heat store (1) with a heat-flow connection to a latent heat storing material (3). The device comprises a component of a thickening agent such as a copolymer the transparency of which changes with the latent heat loading state. The transparency is measured using measurement devices (4, 5). The copolymer etc. is mixed in with the latent heat storing material.
