20160061534 | Latent Thermal Energy System (LTES) Bubbling Tank System - For a latent thermal energy storage (LTES) system comprising phase change material (PCM) slurry, it is problematic to recover thermal energy by crystallizing out solid components from slurry mixtures. It is because the solidifying components form a solid layer of low thermal conductivity on the heat transfer surfaces making heat transfer inefficient. This invention allows an effective thermal energy recovery readily achievable by using gaseous or liquid bubbles of immiscible heat transfer fluid (HTF) in close contact with the phase change material (PCM) slurry mixtures. The circulating immiscible HTF, free of solidifying components, is used for releasing thermal energy through cold heat transfer surfaces to the heat users. A process comprising a multi-chamber LTES system has been devised for applications in the concentrated solar power (CSP) plants using a PCM binary slurry of Li | 03-03-2016 |
