9860118 This Small Business Innovation Research (SBIR) Phase I project will examine a novel retrofitable, high efficiency, variable capacity cooling system that uses the expansion/condensation cycle in a new way. Industry uses significant amounts of energy for air conditioning, water chilling, process cooling, and refrigeration. By using a novel refrigerant combined with an adjustable expansion device, system capacity may be incrementally increased by 30 to 50 percent on demand, while simultaneously achieving a 5-10 percent increase in energy efficiency. Phase I objectives are to identify suitable candidate refrigerants, assemble a bench-top test unit, and perform tests and cost analysis to establish feasibility. Candidate refrigerants will be identified using a systematic evaluation process. Bench-top tests will measure cooling capacity and energy efficiency with and without the novel improvement so that a direct comparison can be made. Performance and costs will be estimated for a range of cooling applications. The new technology could be designed in or retrofitted to cooling systems and would have wide application in all types of refrigeration, air conditioning, water chilling, and process cooling systems. Based on the size of current industrial, transportation, and domestic cooling markets, the potential market is $100 million to $1 billion annually for a new variable capacity cooling system.

9860118 这个小型企业创新研究 (SBIR) 第一阶段项目将研究一种新型可改造、高效、可变容量的冷却系统，该系统以新的方式使用膨胀/冷凝循环。 工业使用大量能源用于空调、水冷却、工艺冷却和制冷。 通过使用新型制冷剂与可调节膨胀装置相结合，系统容量可根据需要逐步增加 30% 至 50%，同时实现能源效率提高 5% 至 10%。 第一阶段的目标是确定合适的候选制冷剂，组装台式测试装置，并进行测试和成本分析以确定可行性。 将使用系统评估流程来确定候选制冷剂。 台式测试将测量有或没有新颖改进的冷却能力和能源效率，以便进行直接比较。 将对一系列冷却应用的性能和成本进行估计。 这项新技术可以在冷却系统中进行设计或改造，并将广泛应用于所有类型的制冷、空调、水冷却和过程冷却系统。 根据当前工业、交通和家庭冷却市场的规模，新型可变容量冷却系统的潜在市场每年为 1 亿至 10 亿美元。
