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

该项目的更广泛的影响/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，以及监管机构的天然制冷剂。不幸的是，没有一种最先进的系统可以同时解决所有这些问题。工业/商业电池仍然负担不起，制冷成本占零售店的60%？S电费和设备制造商只是通过新的蒸汽压缩架构实现了逐步提高的效率。该项目引入了一种嵌入自然制冷冷却循环的储能技术，可提供负荷转移服务，并将商用冷冻机的电力购买量减少40%。更重要的是，它在没有政府激励的情况下实现了这一点，使用了天然的、接近环境的材料。这个小型企业创新研究(SBIR)第二阶段项目将研究一种利用水作为储存材料的能源储存技术，在一个延迟的冰点抑制制冷周期中使用水。该项目将侧重于10kWth系统的内部测试、第三方验证和商业演示。在低温制冷建筑中的成功整合需要以防滑/废热整合为重点的工业设计、为所需部件/系统修订提供信息的验证测试和示范，以监测、学习和修订技术，为扩大规模做准备。

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.
