摘　　要：水合物蓄冷技术应用的关键是水合物的快速成核与生长。探讨了多孔介质、醇、电解质、表面活性剂、纳米颗粒等影响水合物结晶成核诱导时间、生长速度和蓄冷密度等关键因素。通过合适的添加剂制成乳液和纳米乳液,降低了水合物成核诱导时间,减少了水合物形成过冷度。纳米乳液中水合物可在静态系统中蓄冷。The key of hydrate cold storage technology is to promote hydrate nucleation and growth. The effects on hydrate crystallization nucleation induction time, the growth speed and storage density are studied with porous medium, alcohol, electrolyte, surfactants and nanoparticles in this work. Emulsion and nano emulsion are produced with additives. Nucleation induction time and subcooling of hydrate formation are reduced in emulsion and nano emulsion. Hydrate can form to store energy in a quiescent system in nano emulsion.
