制备了一种新型相变乳剂（PCE），并用DSC法测定了其潜热。为了分析其在管道系统中传热的可行性，建立了实验系统。测量了PCE在湍流中的压降，讨论了石蜡浓度和流速等因素对PCE的影响。根据PCE的压力特性和潜热，可以得到相同管径和一定传热量下PCE对水的泵送耗电率。结果表明，与水相比，PCE的质量流量和泵送功耗大大降低。例如，在V=0.6m/s（20%和30wt%）时，降幅可达约73%。此外，结果表明，在一定的流速范围内，PCE为20wt%可以获得与PCE为30wt%几乎相同的泵浦功耗节省。最后对PCE在余热利用、电锅炉利用和太阳能利用等方面的应用进行了评述。
A novel phase change emulsion (PCE) was prepared and its latent heat was measured by DSC. To analyze its feasibility in heat transportation through a piping system, an experimental system was built. The pressure drop of the PCE for turbulent flow was measured and the effects of such facts as the paraffin concentration and flow velocity were discussed. According to the pressure characteristic and latent heat of the PCE, the pumping power consumption rates of PCE to water under the same pipe diameter and a given heat transportation quantity can be obtained. The results show that mass flow rate and pumping power consumption of the PCE decrease greatly compared with water. For example, the decrease can be up to about 73% at V=0.6m/s (20 and 30wt%). Furthermore, the results show that PCE of 20wt% can obtain almost the same pumping power consumption savings as PCE of 30wt% in a certain flow velocity range. Finally, the applications of the PCE in the area of waste heat usage, electrical boiler and solar energy usage were commented.
