The role of secondary refrigerants is expected to grow as the focus on the reduction of greenhouse gas emissions increases. The effectiveness of secondary refrigerants can be improved when phase changing media are introduced in place of single phase media. Operating at temperatures below the freezing point of water, ice slurry facilitates several efficiency improvements such as reductions in pumping energy consumption as well as lowering the required temperature difference in heat exchangers due to the beneficial thermo-physical properties of ice slurry. Research has shown that ice slurry can be engineered to have ideal ice particle characteristics so that it can be easily stored in tanks without agglomeration and then be extractable for pumping at very high ice fraction without plugging. In addition ice slurry can be used in many direct contact food and medical protective cooling applications. This paper provides an overview of the latest developments in ice slurry technology.
随着对减少温室气体排放的关注度不断提高，二次制冷剂的作用有望增强。当引入相变介质替代单相介质时，二次制冷剂的效能可以得到提升。冰浆在低于水的冰点的温度下运行，由于其有益的热物理性质，有助于提高多种效率，如降低泵送能耗以及减小热交换器所需的温差。研究表明，可以设计出具有理想冰颗粒特性的冰浆，使其能够轻松存储在罐中而不结块，然后在高含冰率下抽取而不堵塞。此外，冰浆可用于许多直接接触食品和医疗防护的冷却应用。本文概述了冰浆技术的最新发展情况。
