Latent-heat accumulator useful in a water heater, comprises a container with a first latent-heat storage material having a first melting temperature and a crystallization seed material having a second melting temperature

摘要

The latent-heat accumulator (1) comprises a container (2) with a first latent-heat storage material having a first melting temperature and a crystallization seed material having a second melting temperature of 45-55[deg] C for initiating a crystallization of the first latent-heat storage material, where the first latent-heat storage material indirectly contacts with the crystallization seed material and the first melting temperature is greater than the second melting temperature. The container is made of corrosion-resistant steel or steel with corrosion-resistant coating. The latent-heat accumulator (1) comprises a container (2) with a first latent-heat storage material having a first melting temperature and a crystallization seed material having a second melting temperature of 45-55[deg] C for initiating a crystallization of the first latent-heat storage material, where the first latent-heat storage material indirectly contacts with the crystallization seed material and the first melting temperature is greater than the second melting temperature. The container is made of corrosion-resistant steel or steel with corrosion-resistant coating. The crystallization seed material is a second latent-heat storage material, and is partially incorporated into the first latent-heat storage material as a related material accumulation without intermixing with the first latent-heat storage material. The first latent-heat storage material to the crystallization seed material is present in a ratio of 100:1 in the container related to the mass. Independent claims are included for: (1) a water heater; and (2) a method for manufacturing a latent-heat accumulator.
