摘　　要：相变流体由于在相变前后都能保持流动状态，可以像普通流体一样通过泵和管道系统输送。由于存在固一液相变，相变流体储能密度及输送密度远高于相同温差下的水，因此可以使循环流量大幅降低，从而降低循环能耗，实现节能。综述了相变乳状液、相变微胶囊、水合物浆在蓄能及潜热输送方面的研究进展，并对其发展前景进行了展望。Phase change fluid can keep it fluidity during the phase change period. So,it can be transported through pipes by pumps. Owning to the solid-fluid phase change, the thermal storage and heat transportation density of phase change fluid are much higher than that of water under the same temperature difference. For given a heat transportation quantity, the mass flow rate and the pump consumption for phase change fluid can be reduced greatly as compared with that for water. Research progress in phase change emulsion, microencapsulated phase change materials and hydrate slurry is also reviewed. Frathermore, the development of phase change fluid is prospected.
