This Small Business Innovation Research (SBIR) Phase I project aims to incorporate nanoparticles and filtration membranes into vapor compression systems to improve energy efficiency. The approach is to identify nanoparticles with proper surface properties and suspend these nanoparticles in a surfactant type base material. This will not only enable the nanofluid with the refrigerant to improve the heat transfer occurring in the condenser of a typical vapor compression system, but also solve the problems such as sedimentation, cohesion and corrosion that happen with conventional heterogeneous solid liquid mixtures. A novel membrane system will be introduced to collect the nanoparticles at the outlet of the condenser and return the particles to the inlet of the condenser, thereby preventing particles from entering the compressor. The broader/commercial impact of this project will be the potential to improve the energy efficiency in vapor compression systems. There is a demand for high performance cooling systems used in medical devices, computer chips, residential appliances, industrial cooling and refrigeration systems. Nanofluids have been known for their superior heat transfer properties. The challenge is how to introduce the nanofluids into a vapor compression system, which is addressed by this project. The anticipated result of this project is about 10% reduction in energy consumption of vapor compression systems.

这个小型企业创新研究（SBIR）第一阶段项目旨在将纳米颗粒和过滤膜纳入蒸汽压缩系统，以提高能源效率。 该方法是识别具有适当表面性质的纳米颗粒，并将这些纳米颗粒悬浮在表面活性剂类型的基础材料中。 这将不仅使纳米流体与制冷剂能够改善在典型的蒸汽压缩系统的冷凝器中发生的热传递，而且还解决了传统的非均质固液混合物发生的诸如沉降、凝聚和腐蚀的问题。 将引入一种新型的膜系统，在冷凝器的出口处收集纳米颗粒，并将颗粒返回到冷凝器的入口，从而防止颗粒进入压缩机。该项目的更广泛/商业影响将是提高蒸汽压缩系统能效的潜力。 存在对用于医疗设备、计算机芯片、家用电器、工业冷却和制冷系统的高性能冷却系统的需求。 纳米流体因其优越的上级传热性能而闻名。 挑战是如何将纳米流体引入蒸汽压缩系统，这是本项目所解决的问题。 该项目的预期结果是蒸汽压缩系统的能耗降低约10%。
