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.
