冰/水浆潜热输送是建立节能空调系统的有效技术。Modak等人（2002年）报道了一种新的表面活性剂体系，在该体系中，冰颗粒的附聚得到了很好的控制，同时也得到了有效的湍流减阻。然而，该系统需要添加相当大量的氯化钠。本文提出了将两性表面活性剂与合适的无腐蚀性盐水组合使用来制备冰/水浆料。结果表明，新制备的冰/水浆体具有良好的冰粒分散性，与原有的冰/水浆体相比，其流动性有了很大的改善。由此获得的冰/水浆是有希望的，用于通过利用表面活性剂减阻和潜热输送的高效传热技术。
Latent heat transportation by ice/water slurry is an effective technology to establish the energy saving air conditioning system. Modak et al. (2002) reported a new surfactant system in which the good agglomeration control of ice particles was available, and effective turbulent drag reduction was simultaneously attained. However, this system needed the addition of a considerable amount of sodium chloride. In this paper, the combined use of zwitterionic surfactant with a suitable brine with no corrosive characteristic is proposed to prepare ice/water slurry. It is certified that newly prepared ice/water slurry shows a good dispersion condition of ice particles and the flowability of the slurry is much improved if it is compared with the previous ice/water slurries. The ice/water slurry thus obtained is promising for the use of the high efficiency heat transportation technology by utilizing surfactant drag reduction and latent heat transportation.
