摘　　要：选取在蓄能型制冷空调中常用的石蜡制备了质量分数为30％的相变乳液，研究了石蜡相变乳液的微观形貌、粒度分布、蓄能特性以及在蓄能空调中的应用与优势。实验结果表明，制备的3种相变温度不同的石蜡乳液微粒粒径均分布在1～10μm之间。在6℃温差下，单位质量石蜡乳液相变蓄能量是水的1．8～3倍之间。该类型乳液具有较高的蓄能密度，可作为制冷空调相变蓄能与输运介质，在降低循环流量和动力能耗，实现节能型蓄能制冷空调方面具有一定的应用价值。The experiment selected three kinds of paraffin material which had different phase change temperature and prepared RT phase change emulsion（30wt%）. The micromorphology, particle size distribution and energy storage char- acteristics of the three emulsion were studied. The application of the phase change emulsion in the energy-storage air condi- tioning was also explored. The results showed that the particles size was within the range of 1-10μm. The emulsions had a high heat capacity which was 1.8-3 times as high as that of water in a temperature difference of 6℃within the correspond- ing phase transformation temperature ranges. This type emulsion had a higher energy storage capacity and can be used as a latent heat storage or latent heat transport medium. The emulsions had extensive application value on energy saving.
