SBIR Phase II: Regenerative Freeze Suppression for Thermally Bound Energy Storage Systems

该项目更广泛的影响/商业潜力包括缓解公用事业的高峰需求，降低零售商店的冷冻机运营成本，以及为监管机构提供天然制冷剂。不幸的是，没有一个最先进的系统同时解决所有这些问题。工业/商用电池价格难以承受，制冷成本占零售店的60%？的电费和设备制造商只是实现了新的蒸汽压缩架构的增量效率改进。该项目引入了一种嵌入在自然制冷剂冷却循环中的储能技术，可提供负载转移服务，并减少40%的商用冰箱电力采购。更重要的是，它实现了这一目标，在3年的投资回收期内，没有政府的激励措施，使用天然的，接近环境的材料。这个小企业创新研究（SBIR）第二阶段项目将研究一种能量存储技术，利用水作为存储材料，在一个时间延迟，冰点抑制制冷循环。该项目将侧重于10 kWth系统的内部测试、第三方验证和商业演示。在低温制冷体系结构中成功集成需要工业设计重点关注撬装/废热集成、验证测试以通知所需的部件计数/系统修订以及演示，以监控、学习和修订扩展中的技术。

The broader impact/commercial potential of this project includes peak demand relief for utilities, reducedfreezer operating costs for retail stores, and natural refrigerants for regulators. Unfortunately, no state-ofthe-art system simultaneously addresses all these issues. Industrial/commercial batteries remainunaffordable, refrigeration costs account for 60% of a retail store?s electricity bills and equipmentmanufacturers are only realizing incremental efficiency improvements with new vapor compressionarchitectures. This project introduces an energy storage technology, embedded in a natural refrigerantcooling cycle, that provides load-shifting services and a 40% reduction in commercial freezer electricalpurchases. More importantly, it achieves this at a 3-year payback without government incentives usingnatural, near ambient, materials.This Small Business Innovation Research (SBIR) Phase II project will investigate an energy storagetechnique utilizing water as the storage material in a time delayed, freeze-point-suppression refrigerationcycle. The project will focus on the internal testing, third party validation and commercial demonstrationof a 10kWth system. Successful integration within low temperature refrigeration architectures requiresindustrial design focused on skid/waste heat integration, validation testing to inform required part countreductions/system revisions and demonstration to monitor, learn and revise the technology in preparationfor scale up.
